Bioreactor Market Size Worth Over $470mn By 2023: Fermentor

Bioreactor market size is estimated to exceed USD 470 million by 2023 and is likely to grow at a CAGR of over 18% from 2016 to 2023.

Low operational cost accompanied by minor requirement for maintenance and monitoring compared to traditional ones is anticipated to drive industry demand. In addition, low energy consumption coupled with simplicity in culturing of marine microorganism namely algae is likely to propel the industry demand for this system over the several forthcoming years. Single use bioreactor market size is likely to exceed USD 500 million by 2023.

Intense growth potential of biologics industry is likely to offer massive growth avenues to the industry participants over the forecast period. Furthermore, lack of availability of sterilized sensors is anticipated to hider the industry growth. Low volume capacity of these systems is likely to challenge the industry demand for bioreactors from 2016 to 2023.
  • Bioreactor manufacturer
  • fermentation tank
  • GMP Fermentation system

  • The bioreactor market can be segmented on the basis of product, molecule, cell, technology and end use. On the basis of product type it can be segregated as recombinant proteins and monoclonal antibodies. Based on cell type, the industry can be segmented into bacteria, mammalian cells as well as yeast. Mammalian cells are anticipated to be the fastest and largest growing in the industry. The spur can be subjected to higher effectiveness of biomolecules exhibited by mammalian cells.

    On the basis of technology the industry can be segmented into wave-induced motion SUB, stirred SUB and single use bubble column bioreactor. Wave-induced motion SUB sector is anticipated to account for the major share and is expected to grow at the highest rate over the forecast period. On the basis of molecule the industry can be segregated into vaccines, monoclonal antibodies (MAbs), gene therapy, recombinant proteins and stem cells. Based on end user the industry can be segmented as R&D department and bio pharmaceutical manufacturers. R&D can be further segregated into biopharmaceutical manufacturers, CROs and research institutes.

    Vendors are anticipated to expand the range of options offered along with the flexibility of systems, facilitating users to experiment with different amalgamations of bioprocessing components. Proliferating R&D through commercial production and pilot-scale, mixing & matching systems in order to find the best solution for a particular application is expected to fuel the industry over the several upcoming years.

    Bioreactors that contain disposable bags are proficiently used in the medical sector instead of the ones with culture vessel made of glass or stainless steel. As pharmaceutical companies manufacture diverse drugs using the same facility without negotiating the quality of the product produced and thus operates in various successive batches. For such scenarios, the disposable bioreactors are the preferred ones. As these reactors does not require any additional sterilization or cleaning work.

    Portable bioreactor from MIT produces medications, vaccines on-demand

    Imagine a cross between one of those multi-color retractable pens and an epi-pen. But instead of colors, the device would have different medications. Now combine this with a tiny, droplet-sized sweatshop full of obedient single-celled organisms genetically engineered to produce those medications, and you've got what a team from MIT just published in Nature Communications: A new project, with funding from DARPA, that has demonstrated the ability to synthesize multiple medications on-demand and as-needed using yeast. The discovery could soon revolutionize our ability to deliver medicine after natural disasters or to remote locations.

  • scale up bioreactor
  • scale down bioreactor
  • small scale bioreactor
  • Let's stick with the metaphor of an epi-pen. First, the user presses the actuator, which mixes a chemical trigger into a culture of engineered Pichia pastoris cells. Upon exposure to certain chemical triggers, the cells are programmed to produce a protein: in the report, the team used estrogen β-estradiol, which caused the cells to express recombinant human growth hormone (rHGH), and also methanol, which induced the same culture of yeast to make interferon. By controlling the concentration of the chemical trigger and the population of P. pastoris, the team demonstrated that they could make their device produce a dose of either interferon or rHGH on command. To switch between products, they just pushed another button on the microbioreactor, which flushes out the cell culture with clean, sterile fluid.

    What Need to Pay Attention When Using a Electric Wrench?

    Electric wrench is a tool to tighten the bolts which to the power supply or battery powered wrench. Electric wrench is mainly used in steel industry installation, and used to install steel structure high strength bolts. The high strength bolts are used to connect steel contacts, usually occurs by way of a bolt group.
    Introduce the attentions in use of electric wrench:
    1, Pull electric wrench force should be uniform and soft, absolutely do not use short, impulsive force to turn. Because the tug will produce an impulse, at the stop force moment, the screw or bolt may have been twisted too far.
    2, Contaminants can interfere with accurate torque values. If parts or screw has the pollutant, then we will not get the correct torque value.
    3, Friction is a common phenomenon, but there are two aspects of the role of good or bad. The good news is keeping parts together; the bad news is that in the tightening, it may lead to erroneous results. A mechanic hand tight connection with only 10% - 20% for tension, and in many cases, 40% - 50% of the torque is used to overcome the friction between the bolt head and the parts of, along the screw bolt and a screw hole of the spouse thread surface also produce additional friction. So when tightening the bolts, all these friction factors and other factors should be taken into account.
    4, Tighten the screw thread on the injury or obstacle of the nut or bolt, to pay attention to the need for additional torque through the damaged parts of the site to be added to the recommended torque value.

    What is A Piping Expansion Joint

    An expansion joint is installed in piping systems for a couple of reasons. Not only can they be used to absorb vibrations and shock, they can also be used to relieve anchor stress, reduce noise, and compensate for misalignment. Certain expansion joints are also designed for thermal expansion in very hot applications.

    Expansion joints allow pipes to move in three different ways:
  • Axial compression or extension
  • Lateral offset
  • Angular deflection
  • They typically come in three different materials to cover a variety of applications.

    Metal - Metal expansion joints are mostly used in applications where thermal expansion is an issue. When the temperature of the pipe increases, the metal expansion joint compresses to compensate for the movement, taking stress off the anchors and the pipe. A metal expansion joint is a prime example of how to handle expanding hot pipes.

    Rubber - Rubber can be used for thermal expansion, and it also absorbs vibration and shock waves extremely well. That's why this type of expansion joint is great for minimizing the transmission of noise, vibration from other equipment to protect equipment like pumps. They also work as shock absorbers to minimize trauma caused by water hammer, pressure surges, and seismic events (not that we get a lot of earthquakes in Wisconsin...).

    Braided - Braided stainless hoses with flexible or metal liners aren't technically an expansion joint, more of a flexible connector. They work well in high pressure and temperature applications requiring vibration dampening or pipe misalignments.

    These are often used on pumps and other equipment to help eliminate thrust load on the equipment nozzles due to thermal expansion. Eliminating that load is critical to pump performance.

    Braids provide lateral an angular movement. They also absorb vibration rather well.

  • Which Factors to Consider When Selecting a Valve

    Aloyco Stainless Steel Gate ValveChoosing a valve for a certain application isn't a beginner's task. Sometimes an incorrect valve can be selected if you aren't careful. So, what do you need to know to begin your search for the right valve?

    Know Your Process Conditions

    Without knowing or sharing the process conditions, the wrong type of valve could be selected. For example, a customer requests a globe valve without sharing their process conditions. Unknown to our engineers, the customer's application needs a large capacity of flow that would perform better with a butterfly or ball valve. Problems might arise in the future with the capacity of the globe valve. This is why it is critical to know the process conditions. A valve can only be guaranteed when all of the process conditions are known!

    Identify your Valve Function

    You must know how your valve will function in your application. Is it normally open? Normally closed? Do you need to use it to control flow? Is it a 2-way, 3-way, or multipurpose valve? We can help you identify your valve function if you are unsure. Knowing the process conditions of the valve is crucial.

    If you're still not sure how to select a valve, contact us! Our experienced engineers are happy to help you find the proper valve for your applications.

    Do You Know Which Time Need to Change A Load Rope

    Safety should be your primary consideration when it comes to handling lifting equipment. When you do not practise adequate care to minimise risk elements, you put your life and others' lives at risk and this is the last thing that you will want to be affected with. Fatalities at work sites are commonly caused by dropped loads and needless to mention, such incidents can be attributed to the use of excessively worn load chain and ropes. While timely inspection and maintenance can prevent mishaps, the fact is that even a little bit of negligence can reverse situations and cause irrecoverable damages.

    UK law requires companies to inspect above the hook equipment every 12 months whereas the equipment that is used more intensely should be examined on a frequent basis. It is quite easy to inspect load chains and a visual inspection on a daily basis may help you notice the danger signs. Check if the diameter of the rope looks worn. While this is one of the most obvious signs, you should look for other signs such as splintering and kinking. If you spot a minor splintering, monitor it regularly so that you can prevent an imminent accident. If the splintering appears to be substantial, you need to replace the existing rope with a new rope.

    When it comes to inspecting chains, you need to adopt a slightly different approach. The lower inside half of the chain link is subjected to most wear and tear as this is the area that faces the maximum amount of pressure. Excessive wear is often attributed to the lack of lubrication to the inner sides of the links. There can be a lot of doubts and questions during inspection which may put you in a "change-not change" dilemma. The best way to deal with such scenarios is to eliminate your doubt completely. Change - if you think that this will reduce risk, save lives, and give you peace of mind.

    When searching for a reliable supplier for a new load rope, regardless of the manufacturer, size or complexity Cranes-UK are the UK's premier crane servicing company offering nationwide support, installation and global supply of crane components, give them a call or visit their informative website for further details.

  • Which Major Considerations Need to be Considered When You Buy A Winch

    With the cost of a winch ranging from 100 pounds to thousands of pounds, you may find it hard to select a winch that not only suits your budget, but serves your purpose as well. There are a few major considerations that one should take into account when you purchase a winch so that you feel good about your investment at the end of the day. Think about your intended usage before you determine how much winch you exactly need. You also need to have knowledge about the purpose and safe use of winch accessories. As a rule of thumb, winch rating is calculated by multiplying the gross load weight by 1.5. The product indicates your minimum winch size. However, this is just the minimum rating and there may be situations that may demand your winch capacity to be exceeded. Hence, you should carefully determine usage before you make a choice.

    Secondly, your choice of winch motor should also be determined by the frequency and intensity of use. Light duty winching and permanent magnet motors work well together whereas heavier and more frequent winching will demand the use of a Series Wound winch. Hydraulic winches are an appropriate option if you winch throughout the day regularly and beyond any electrical winch's capability. The weight of the winch may be one of your primary considerations and the dimensions of your winch may also influence your choice as well as the orientation of which it is mounted and the rope deploys. Winches may come with an Integrated or Remote Solenoid Pack and each option has its own set of advantages, including their ability to reduce the space required to mount the winch.

    Read the manufacturer's warranty thoroughly to be aware of the warranty coverage time and other terms and conditions. Consider serviceability as a vital decision-making criterion as you need to ensure that you find a service centre whenever you need it most. You will surely not want to spend your time hunting down hard to find replacements of broken parts after the warranty period expires.

    The Industrial Mixer Is Noisy! What's Wrong?

    A noisy industrial mixer is usually not a healthy mixer. If you're hearing abnormal noises coming from your mixer, there is probably a larger underlying issue. Let's go over a few common culprits and their respective fixes.

    LOOSE FOUNDATION BOLTS

    Mixer foundation bolts should not be vibrating, shaking, or visibly loose. If they are, you might have a weak mounting structure or loose hold down bolts. To fix this, first inspect the mounting point of the reducer. If you find loose bolts, tighten them as necessary. Otherwise you might have an unstable mounting structure that needs to be reinforced.

    BEARING FAILURE

    If you can't find any loose bolts or a problem with the mounting structure, you should check your bearings. Bearing failure can occur when the bearing is overloaded or isn't getting enough lubricant.

    Check the rated capacity of the reducer and make sure you're not overworking the bearing. If the capacity is in check, you might need to replace the bearing. When the bearing is replaced, be sure to clean and flush the reducer and fill with recommended lubricant.

    INSUFFICIENT LUBRICATION

    If the level of lubricant inside the reducer is not properly maintained, your industrial mixer will make noise. It is important that the mixer itself is sufficiently lubricated. Be sure to check the lubrication level and adjust to recommended level.

    It is also important that the correct lubrication is used. If the wrong lubrication is being used, flush it out and refill it with the correct lubricant as recommended.

    Noise is your industrial mixer's way of telling you something is wrong. Pay attention to its subtle (and sometimes not so subtle) queues, to correct the issues and ensure your mixer gives your process the best mix for a long time to come.

    EastMachinery Tell you Why Choose a Positive Displacement Pump

    The decision to choose a positive displacement pump over a centrifugal is not always a clear one. They each have very different behaviors and if not familiar with them, it may be difficult to understand how a positive displacement pump could fit into your process.

    Positive displacement pumps are a more efficient choice than centrifugal pumps in some situations. If any of the conditions or applications below are in your process, a positive displacement pump should probably be used.

    1, HIGH VISCOSITY

    Centrifugals have issues pumping viscous liquids, becoming very inefficient at even modest levels. Positive displacement pumps, on the other hand, have no problem moving thick liquids.

    2, LOW FLOW

    Oftentimes, a centrifugal pump is run off its BEP when a lower flow is desired, much to the pump's detriment. If you read our previous post "How To Read a Centrifugal Pump Curve", you'll recall that running a centrifugal off its BEP can cause excessive energy consumption, damage to the pump, and overall poor performance.

    A positive displacement pump, however, is well suited for these conditions, providing constant flow of fluid at a given pump speed.If you're trying to get the pressure or flow you need by operating a centrifugal pump off its best efficiency point (BEP), a positive displacement pump may be a better choice.

    3, METERING

    Positive displacement pumps are an ideal choice for metering applications. They deliver constant flow, allowing them to easily meet process requirements. Some common types of positive displacement pumps used for metering are:

  • Peristaltic
  • Gear
  • Diaphragm
  • Plunger
  • Piston
  • 4, HIGH PRESSURE REQUIREMENTS

    Positive displacement pumps are excellent for applications that require high pressure, with some models producing over 1,000 psi (2,300 ft). Due to the positive displacement pump's design however, if kept in operation against a closed discharge valve, it will continue to build pressure until the line bursts, the pump is damaged, or both.

    5, SHEAR SENSITIVE LIQUIDS

    Centrifugal pumps generally operate at higher speeds when compared to positive displacement pumps. the higher speeds can shear liquids, making centrifugal pumps a poor choice for liquids like tomato paste and latex paint. Positive displacement pumps operating at lower speeds can be more gentle on products, and are usually preferred in these types of applications.

    Centrifugal pumps and positive displacement pumps behave very differently. Understanding their behaviors can help you be sure to choose the right one for your application.

  • Failed Mechanical Seal Puts Cold Storage Facility Hot On The Trail For Solution

    A company specializing in temperature-controlled warehousing and logistics for the food industry recognized an issue concerning a failed mechanical seal on a Goulds 3196 ammonia pump. Being that ammonia pumps are critical to maintaining temperatures at a cold storage facility, identifying the problem and appropriate solution was dire. In conjunction with the facility's Maintenance department, the engineering and service teams at Crane Engineering worked tirelessly to troubleshoot and identify the right solution. 

    This cold storage facility has two primary pumps used to maintain temperature throughout the facility. One of these pumps experienced catastrophic seal failure less than one year after it was replaced by the customer. To make things worse, the other critical pump wasn't doing much better as it slowly leaked as well. The customer was in a tough situation as it was now June and the weather was really starting to heat up – making it even more difficult to maintain the cold temperatures. Time was running out.

    Instead of simply installing a new seal, the team at Crane Engineering made the decision to troubleshoot and determine why the customer-installed seal failed in under one year. Oftentimes there is an underlying cause for seal failures, especially when they happen within a short period of time. It was determined that seal selection was not the issue, this style of seal is commonly used across the cold storage industry and is widely accepted due to its reliability.

    THE SOLUTION

    The pump was disassembled by Crane Engineering's service team in Kimberly, Wisconsin. The condition of critical parts was assessed to determine if replacing the seal would fix the problem. With a number of components showing significant wear, it was determined that replacing the seal would only be a temporary solution, as the worn components directly impact the overall reliability of the seal.

    A Crane Engineering Account Manager also noticed the seal's piping plan wasn't ideal as it sloped in the wrong direction with tight 90 degree elbows instead of gentle slopes. A proper pipe installation method was discussed and necessary changes were made to ensure adequate lubrication.

    THE RESULTS

    The pump repair and installation took a total of two days. A number of causes for the shortened seal life were found, and necessary components on the pump were either repaired or replaced. Since then, the pump has operated flawlessly, and the facility came out with a greater depth of knowledge on the subject. Root cause analysis of the failed mechanical seal helped to ensure maintenance personnel could extend the life of their pumps minimizing costs associated with repeated mechanical seal failure.

    To be continued - A Few Simple Principles Guide You To The Best Seal Flush Plan

    --- To be continued

    3. External Flush

    The external flush method is used when it's desirable to isolate the seal from the pumped fluid. However, if you do not have a suitable flushing liquid available or if diluting the pumped fluid with the flushing liquid is unacceptable, this is not an optimal solution. This method consists of a minimal flow of a clean, relatively cool liquid (usually water) from an external source injected into the seal gland flush connection at a pressure higher than the pump seal chamber pressure. The external flushing liquid flows past the seal and into the pump, mixing with the pumped fluid. Usually a flushing liquid pressure of about 10-15 psi above the pump seal chamber pressure is sufficient.

    Flow rates of about 0.25-0.50 gpm are typical, but any positive flow is probably adequate unless there is a need for a specific flow rate to keep the seal temperature at a desired level. A restriction bushing or lip seal can be installed at the seal chamber throat to minimize the flush water flow. A control valve, gauge, and flow meter should be installed in the flushing liquid supply line to provide the control functions necessary to set and monitor the flushing liquid supply, with the flow meter being the most important so that a positive flow of flushing liquid into the pump can be confirmed.

    An external flush can perform several functions:
  • Flushes damaging solids away from the seal
  • Isolates the seal from the pumped fluid
  • Cools the seal
  • Carries away seal generated heat
  • But, it also has its disadvantages:
  • Additional costs
  • Potential problems may occur when diluting the pumped fluid
  • Possibility of seal failure when the flushing liquid supply is interrupted by system failure or human error


  • 4. Induced Closed Loop Circulation System

    Not common, but may be recommended when it's necessary to control the temperature at the seal to a level different than the pumped fluid. It can only be used with a seal that has special circulating features. The seal must be equipped with a device that generates some circulation flow (basically a small impeller) and piping in and out of the seal chamber through a heat exchanger. In most cases a bypass flush with a heat exchanger would be the more reliable method to obtain the same results, but an induced closed loop circulation system can be used to reduce the heating/cooling load since only a small amount of liquid contained in the seal chamber is circulating through the heat exchanger.

    If you are considering an induced closed loop circulation system contact your local seal supplier to come up with the best system design.

  • A Few Simple Principles Guide You To The Best Seal Flush Plan - EastMachinery

    Are you Tired to watching your money spiral down the drain from mechanical seal repair or replacement? A few simple principles can guide you to the best seal flush plan for your installed mechanical seal, allowing the seal to operate in an environment that generates optimal seal life yet minimizes costs from water usage and product dilution. Today, we'll identify 4 flush piping plans for single mechanical seals and how they work. In future articles, we'll dive into double mechanical seals and packing, so stay tuned!

    1. No Flush

    Can only be used if the pumped fluid is clean, does not exceed the temperature limits of the seal, is compatible with the seal components, and is in no danger of vaporizing or solidifying when exposed to the additional friction heat generated by the seal. If this plan is used, a tapered or self-venting seal chamber is highly recommended.

    2. Bypass Flush

    This method is used when the pumped fluid is clean, does not exceed the temperature limits of the seal, and is compatible with the seal components. It's not recommended if the pumped fluid contains solids that could adversely affect the seal or if the temperature of the pumped fluid exceeds the maximum temperature for the seal.

    Normally, this method consists of piping run from the pump discharge to the flush connection on the seal gland, providing flow from the pump, past the seal, and back into the pump through the seal chamber throat. It can also be piped from the flush connection on the seal gland back to the pump suction, which would result in the flow going the opposite direction and can have the added benefit of lowering the operating pressure at the seal. If warranted, accessories such as a heat exchanger or pressure reducing orifice can be installed in the piping.

    A bypass flush provides circulation flow past the seal faces to carry away seal generated heat, so the seal operating temperature will stabilize at the temperature of the pumped fluid. This method is simple, reliable, and inexpensive. It does not result in product dilution and is the preferred seal flush method unless there is a specific reason not to use it.

  • EastMachinery Tell you Why Get Low Flow and Pressure From A High Pressure Pump?

    Every facility manager knows that he or she could be held at least partially responsible for periods of reduced productivity and increased downtime. But what happens when a critical high pressure pump doesn't meet performance expectations? Leveraging the skills and expertise of the Crane Engineering team, one manufacturer solved this problem.

    The Manufacturer's Challenge

    A food manufacturing plant in southern Wisconsin specializing in the production and packaging of carrots, corn, mixed vegetables, peas, potatoes, and stew vegetables installed high pressure pumps to supply water to the plant for clean up after a long day of production. The main purpose of these pumps was to supply enough flow and pressure to hoses placed around the plant for cleaning and pressure washing work areas. After these pumps were installed, they still weren't seeing enough flow and pressure to all of the nozzles and hoses placed throughout the plant. This was a problem that needed to be addressed.

    The company was running three (3) Roto-Jet high pressure pumps in parallel to supply flow and pressure to the plant. Many food manufacturing plants, including this one, use fixed flow orifices on the discharge of the pump to protect it from running off the curve and destroying the pump, which could be detrimental in terms of maintenance costs and unscheduled downtime for the company.

    Why A Fixed Flow Orifice Is Not Appropriate

    Using the fixed flow orifice on the discharge of the pump causes a significant amount of wasted energy and places limitations on the capacity and production of the pump.

    In coordination with the facility's maintenance department, it was decided to provide a long-term, more substantial solution by removing the orifices and sticking with the standard size discharge. The team at Crane Engineering then sized, selected, and installed a pressure regulating valve in the discharge of the pump with a controller to regulate the valve. This allowed for full control of the high pressure pumps, while increasing flow rate and discharge pressure throughout the plant. Problem solved!

    Benefits of the Pressure Regulator and Controller Setup

    Using the pressure regulator and controller setup versus the flow orifice helped to increase productivity, and also ensured consistency across the board for higher flow rates and pressure for which the pump was initially designed.

    How A Paper Mill Found the Right Mechanical Seal for A Pulper - EastMachinery

    Is there anything tougher to seal than a bottom entering pulper? Rotors on these machines take a beating from market pulp bales and recycled material, causing large radial shaft deflections. Traditionally, seals have been packed, allowing for leakage, loss of product, wet floors, and thousands of dollars wasted on downtime and gearbox repair.
    The maintenance department at New Page decided they weren't going to take it anymore. The leaking seal on "Slab Broke Pulper" was simply costing them too much. They determined that the seal they needed would have to be fast and easy to install, very low maintenance, and withstand the heavy shock and vibration that occurs during normal operating conditions.
    New Page decided to install a John Crane fully split mechanical seal with compression ring rubber bellows. The rubber bellows would add flexibility and shaft deflection so angular misalignment and run outs were tolerated.
    The mechanical seal they chose accepted:
    • Radial shaft movement of 0.125"
    • Shaft run out up to 0.020"
    • Stuffing box waviness up to 0.030"
    • Axial end play up to 0.060"
    • Out of squareness box face to the shaft of up to 0.100"
    • Temperatures up to 180° F
    • Pressures up to 80 psig
    • Speeds up to 1,800 rpm
    The maintenance team at New Page placed bets on the number of days the mechanical seal would survive, confident the harsh operating conditions would cause it to leak.
    But it never did.
    Fast forward 21 years. The maintenance team is again looking at "Slab Broke Pulper" to investigate an issue concerning pulp break-up. They inspect the unit and find that the same John Crane seal installed in the early 90s remained, and still, no leaks.
    Crane Engineering Account Manager Bob Linder, and Service Technician Dave Holtz, along with two of the mill's maintenance people, rebuilt the seal and promptly put it back into service on "Slab Broke Pulper". Two years later, and despite a bent shaft, the mechanical seal continues to perform against leakage, saving the mill thousands in rebuilt gearboxes and time spent re-packing stuffing boxes.

  • 5 Things You Must Know for Sizing a Pressure Regulator, Correctly!

    A pressure reducing regulator is commonly used to manually control pressure of a liquid, gas or steam. Choosing the right regulator for your application can be challenging. There are 5 variables required to size any pressure regulator and properly calculate Cv: upstream pressure, downstream pressure, flow range, temperature and fluid type. We define each variable and talk about why it's crucial to sizing a pressure regulator.

    Please note: Cv is a coefficient of flow for valve sizing. It's used to quantify valve flow performance and can vary with both size and style of the valve or regulator. Once you calculate the required Cv range, you'll know the valve or regulator is sized correctly to handle the actual flow.

    1. UPSTREAM PRESSURE

    Supply pressure or Inlet pressure. This is the pressure upstream of the regulator. This pressure could be coming off of a main header at 100 psi. If it is a higher pressure, such as 1,000 psi, and your goal is to regulate a much lower pressure, less than 100 psi, then a second regulator may be required to knock down the pressure in two stages: one high pressure regulator and one low pressure regulator.

    2. DOWNSTREAM PRESSURE

    Outlet or Control Pressure set point or range. This is the pressure downstream of the pressure reducing regulator. The pressure levels are what you are attempting to control. It could be a specific pressure point, like 30 psi, or a range of 5 to 20 psi. The difference between upstream and downstream pressure is called a "pressure drop" or "pressure differential".

    3. FLOW RANGE (minimum, maximum and normal)

    It's a good idea to size the regulator at a minimum of 3 separate points in order to get a range of flow requirement. This gives you a safety factor, so the regulator is not over or under-sized.

    4. TEMPERATURE (minimum and maximum)

    Temperature can affect the required Cv. Note that temperature does not affect Cv nearly as much as pressure and flow.

    5. FLUID TYPE

    Determine what fluid is going through the regulator. Is it liquid, gas or steam? What are its properties? Understand that sizing formulas are different for each type of fluid. For example, the formula for critical pressure drop is different than non-critical pressure drop for gases. For steam, you must know whether it's saturated steam or super heated (higher temperature).

    Lubrication, Bearing Design Considerations in Medical Technology



    Lubricant selection may be the specification most overlooked by designers and engineers. Bearing life depends on proper lubrication in terms of both type and amount. In many cases, miniature and smaller instrument bearings are lubricated once for the life time of the device. Thousands of greases and oils are available that are designed to function in a variety of conditions and environments.

    Operating temperature is the primary consideration when selecting a lubricant. Temperature directly impacts the base oil's viscosity, which in turn impacts the ability to support loads. In the world of medical devices, bearing lubricants are subjected to sterilization, temperature extremes, high speed rotation, saline wash down or irrigation, chemicals and reagents, blood, and radiation.

    Lubricant selection not only depends on the operating conditions the bearing will face, but may also be subject to regulatory requirements. Manufacturers of medical devices are often required to use what are known as food-grade lubricants, which are broken into categories based on the likelihood they will contact food.

    H1 lubricants are food-grade lubricants used in food processing environments where there is some possibility of incidental food contact. H2 lubricants are used on equipment and machine parts in locations where there is no possibility that the lubricant or lubricated surface contact food. Finally, H3 lubricants, also known as soluble or edible oil, are used to clean and prevent rust on hooks, trolleys, and similar equipment.

    Due to the wide array of products, price and availability, both a lubrication specialist and the bearing manufacturer should be consulted before making a final lubricant selection.

    Bearing Design Considerations in Medical Technology as Bearing Materials



    All bearings should be manufactured using rings produced from high purity material. For most medical applications, martensitic stainless steel, similar to AISI 440C, is recommended and often required due to regulatory requirements. This material, which can be specified differently depending on its manufacturer, provides for good corrosion resistance and has fine, evenly dispersed carbides which result in lower noise and vibration levels than 440C. This type of stainless steel is very desirable, particularly in high speed devices.

    Nitrogen enhanced martensitic stainless steel is also available, and while it is more expensive it offers up to 5 times the corrosion resistance when compared to traditional "440C type" materials. Other benefits of this material are very low noise levels, extended fatigue life due to its fine structure that contains smaller chromium nitrides (as opposed to chromium carbides) and a high resistance to corrosion resulting from exposure to blood.

    In some cases, balls produced from ceramic materials, such as silicon nitride, can prove beneficial. Ceramic balls are light weight, highly polished, non-magnetic, exhibit high hardness, and resistant to attack from most liquids and chemicals. Ceramic balls greatly improve the high speed capability of the bearing. Bearings made of steel rings and ceramic balls are commonly called hybrid bearings. While ceramic balls have an impressive list of beneficial characteristics for bearing applications, they are not a "cure all" medicine. Due to the high hardness of the ball, contact stress is increased so fatigue life is compromised. So, when the typical failure mode is characterized by fatigue, it's usually best to stick with steel balls.

    Retainers, or ball separators, are typically produced from a 300 series stainless steel. In high speed applications, it is often necessary to use a plastic or phenolic resin "snap-in," or crown, style retainer. For very high speeds, an angular contact bearing with a full machined retainer is recommended. These types of retainers provide increased stability at higher speeds.

    Phenolic resin cages have a porous structure and can be impregnated with oil for additional lubricity. Some of the plastic materials, such as polyamide-imides, contain additives such as graphite and Teflon for additional lubricity in emergency running conditions. A wide array of lightweight plastic material are available, which, can handle temperatures up to 500F and are autoclavable.

    An autoclave is a device used to sterilize surgical tools, dental drills, or other devices by subjecting them to high pressure saturated steam for around 20-30 minutes depending on the size of the load. This is a common practice that can have a negative impact on the bearing materials and lubrication.

    Bearing Grease Consistency White Paper in Eastmachinery

    Bearing grease consistency can greatly affect the performance of the bearing and consequently the performance of the mechanical device or product.

    Most people are familiar with the term "viscosity" as the measurable consistency of oil lubricants.  However, the average person probably does not know what the equivalent measurement for the consistency of grease (hint: it's not viscosity). Bearing grease consistency is measured in "penetration levels".

    Eastmachinery Bearings has created a mini white paper which covers the topic of "Bearing Grease Consistency".  In it the following topics are covered:

    Grease Penetration Definition
    How is Unworked Penetration Measured?
    How is Worked Penetration Measured?
    Comparing Worked and Unworked Penetration
    Channeling Grease Characteristics
    Grease Consistency Plays Role in Preventing Fretting Corrosion

    New Seals Protect Bearings from Harsh Environments - Eastmachinery

    Eastmachinery Bearings LLC now offers specially formulated rubber seals with unique geometries to protect 6000, 6200 and 6300 series ball bearings from moisture, wash-down chemicals, mud and dirt. Applications include outdoor environments, lawn and garden equipment, snow blowers, pumps and compressors, pulleys and idlers and rollers and conveyors.

    Bearings are filled with a special grease lubricant, featuring synthetic base oil with a lithium complex thickener. The grease contains additives to protect against wear and corrosion, and can withstand temperatures from -40°C to +150°C (-40°F to +302°F). The sealed bearings meet ABEC 1 tolerances per A.B.M.A. standard 20, and have modified internal clearances that allow for easy interference fitting of both rings if desired.

    A 6203 bearing, for example, could be treated with this sealing and lubricant technology and the nomenclature would be referred to as 6203-2RES. Other bearing specifications for a sealed 6203-2RES remain the same: bore diameter (17mm), outer diameter (40mm), width (12mm), static load capacity (1,070 lbs.), dynamic load capacity (2,150 lbs.), and maximum speed (9,000 rpm).

    Spherical Bearings in Eastmachinery about Accommodating Misalignment

    Spherical bearings come in many different types to accommodate a wide variety of applications. What all of them have in common is the ability to accommodate misalignment from mounting or shaft deflection.
    Spherical Ball Bearings
    Spherical Roller Bearings
    Spherical Plain Bearings
    Spherical Rod End Bearings
    Spherical Ball Bearings
    More commonly known as Self-Aligning Double Row Ball Bearings, spherical ball bearings are designed to work in applications where severe misalignment exists whether from mounting or shaft deflection. The concave raceway of the outer ring in combination with two rows of balls operates over a wide range of contact angles. Furthermore it aligns itself correctly with the shaft and assembly without causing undue stress on the rest of the bearing assembly. Noteworthy is that the self-aligning ball bearing has the lowest friction of all rolling bearings, which enables it to run cooler even at high speeds. Furthermore, the design allows for easy mounting and dismounting.
    Spherical Roller Bearings
    Spherical Roller Bearings are designed to work in applications where severe misalignment exists whether from mounting or shaft deflection and with relatively heavy radial loads and some axial loads in either direction. They are also extremely resistant to shock loads and their self-aligning feature allows full capacity loading despite shaft deflection. They are very similar in purpose to Self-Aligning Double Row Ball Bearings, except the Spherical Roller Bearings are designed to be more robust by carry heavier loads but at lower maximum speeds.
    Spherical Plain Bearings
    Spherical Plain Bearings (also known as “Spherical Plane Bearings” “Spherical Ball Bushing Bearings” and “Ball Bushings”) are spherical bearings that have an inner ring with a sphere convex outside surface and an outer ring with a correspondingly sphere, but concave inside surface. Their design makes them particularly suitable for bearing arrangements where alignment movements between shaft and housing have to accommodate, or where oscillating or recurrent tilting movements must be permitted at relatively slow sliding speeds.
    Spherical Rod End Bearings
    A Rod End is spherical bearing that consists of an eye-shaped head with integral shank forming a housing and a standard spherical plain bearing, or a spherical plain bearing inner ring, or a spherical plain bearing inner ring and a sliding layer between the bore of the head and the inner ring. As the name implies, they are used at the end of rods and have either a male or female thread for mounting.

    Eastmachinery Bearing Design Considerations for the Food Processing Industry - Seals

    In the fifth (and final) portion of our examination of bearing considerations in the food processing industry, we will be taking a closer look at seals. In food processing plants, bearings are continuously exposed to liquids and various types of particulate debris. Sealed or shielded bearings are the best option for keeping foreign debris out of the interior of the bearing and keeping lubricant in.
    The most common bearing seal material is a nitrile rubber. This type of seal is typically Buna-N bonded to a steel insert. The seal is fixed into a groove in the outer ring. The maximum operating temperature is 240° F. This type of seal makes contact with the inner ring providing better protection in contaminated environments than a metal shield. However, this results in an increase in torque and reduces the maximum speed capability of the bearing, but in almost all cases is a design tradeoff that improves the product life.
    Certain lubricants and chemicals react with rubber. Aside from the Buna-n and nitrile rubber material, other materials are available for higher temperatures and chemical resistance. These include FDA approved silicone rubber seals that can handle a maximum temperature of 400° F and Viton that has good chemical resistance and a maximum operating temperature of 400° F.
    The seal construction can greatly improve its ability to function in extreme environments. Seals can be shrouded in metal, such as stainless steel or galvanized steel. Often called slingers, this type of seal is often found on mounted bearings and the metal shroud helps protect the rubber from abrasion.
    The portion of the seal that contacts the inner ring of the bearing is known as the seal lip. Seals can be designed as single, double or triple lips. The seal lips flare out where the contact the ring provides effective protection against lubricant loss and wet or particulate contaminants. Triple lip seals provide the most protection, but also increase rotational torque substantially compared to single lip designs.
    When lower torque is a design requirement, a non-contact rubber seal based on the labyrinth effect can be utilized. These seals function by creating a path the fluid or debris must navigate in order to penetrate the seal. In bearings, this is typically just a groove in the inner ring. A contact lip seal can be used very effectively in combination with a labyrinth design to provide excellent protection and low torque.
    Teflon and glass reinforced PTFE seals are an excellent material choice in food processing applications. They have outstanding chemical resistance, high and low-temperature capability and exhibit less torque than rubber seals. However, depending on the type of bearing and their construction, these seals are not as robust and can be dislodged if hit directly with a high-velocity stream of fluid.
    Keep in mind, the seals found on most types of bearings are not designed for immersion and fluid penetration will eventually take place. They offer excellent protection from particulate contaminants or a fluid splash and wipe down situation.
    In the food processing industry, bearing life is a major factor contributing to uptime and reliability. The environments bearings encounter in these applications are extremely harsh. Bearings are selected based in operational loads and desired life, but designers must also give careful consideration to protecting bearings from corrosion and contamination and maximizing lubricant life.
    As evidenced, there are a wide range of bearing options to take into account for optimal application performance. Food processing engineers and designers are advised to consult a bearing applications specialist for assistance with calculating environmental factors, load capacity, bearing life and attributes.
    Due to the wide array of products along with price and availability, both a lubrication specialist and the bearing manufacturer should be consulted before making a final lubricant selection.
    There are a wide range of lubrication options to take into account for optimal application performance. Food processing engineers and designers are advised to consult a bearing applications specialist for assistance to best navigate these regulations.
