INTERNATIONAL FLUID POWER SOCIETY

When I started CFC Industrial Training in 1990, we were known as Certified Fluid Consultants and commonly referred to as “CFC.” In 1999, my brother and I combined our two businesses and were known as CFC-Solar, again often referred to as CFC. Several years later, with the advent of the internet and search engines, we officially changed to CFC Industrial Training since we no longer did any training or consulting in the solar arena. I also searched the internet for the phrase “hydraulic training” and 40 pages later, we still did not show up. (However, we did show up on the first page if you searched for “solar.”) The reason I bring this up is because we knew a company that wanted to train us on how to use the internet to our advantage, but we just kept doing what we were used to. It was an eye opener to the hits and request for quotes we received when we finally agreed to the training in this area, changing our name, and understanding the search engine world and the value of keywords. I have been writing troubleshooting articles, as many as 20 a year, for 12 to 15 years. Most are the results of troubleshooting hydraulic systems for customers. Today, when it comes to hydraulic systems, it doesn’t surprise me to see the lack of knowledge many maintenance personnel have. Our hydraulic manufacturers and high-end distributors design high-end electro/hydraulic systems for their customers with no consideration of the customers’ maintenance personnel’s ability to understand, maintain and troubleshoot them. I feel the solution for our industry is to be more aggressive promoting machine specific training programs for the end user’s personnel. This can start by requiring machine specific training after the equipment is installed. It’s our feeling that suppliers and/or the end user should always include extensive machine specific training on any equipment they purchase. Recently, I was teaching at a school for a hydraulic distributors customer and during the class, I was asked to look at a very large front-end loader problem. The dealership for the machine replaced a 5-gear pump stack, a bank of directional valves, and still could not solve the problem of not having any pressure to lift the bucket. They invoiced the user approximately $25,000 and the machine was still out of service. The class and I studied the circuit drawing, checked a remote pressure control in the cab, and found a $6.00 spring was broken! I also owned a hydraulic repair shop in the ‘80s and up to 60% of the pumps we received were in good condition. They were removed due to a lack of pressure caused by a different problem. It was determined that the BP Horizon’s oil field disaster’s number one fault was lack of proper training. I think that over 50% of the hydraulic problems we resolve are a result of the maintenance's personnel lack of adequate training, rather than a lack of effort or ability on their part. Good training pays for itself in uptime and reduced replacement parts.

Investigation of Noise Transmission through Pump Casing

PRESENTED BY: PAUL KALBFLEISCH, RESEARCHER, DAN DING, RESEARCHER, AND MONIKA IVANTYSYNOVA INSTITUTION: PURDUE UNIVERSITY

PURPOSE The goal of the investigation is to account for the large simulation errors and the lack of sufficient experimental validation in an attempt to incrementally validate noise modeling techniques and understand the noise generation by swash plate type axial piston machines. In the process of investigating, the researchers aimed to develop a more robust in situ methodology of experimentally diagnosing and modeling the oscillatory energy with a positive displacement machine.

PROGRESS Resolving vibroacoustic problems involves impact testing that shows there to be high damping in regards to frequencies with high modal density. The higher the damping, the higher the forces of impact. Consequently, the higher the modal, the more accelerometers leading to dependent operational damping and full fluid film isolations. Therefore, the researchers examined the main frequencies of interest and what modeling method should be used. After reviewing which noise modeling technique was most important (analytical, numerical, energy-based or geometrical), the team, with omni-directional sensors such

as microphones and pressure sensors, determined how to bridge the gap between noise generation and perception within structural acoustics. From generation to transmission to propagation to radiation, then finally perception, automated spatial sampling revealed that the in situ methodology was the most beneficial technique to measure the source of pump noise.

NEXT STEPS With the final result supporting in situ experimental methodology, the analysis provided the team with a lot of information regarding the acoustic environment. While measuring more sound than any other experimentations in the past, the researchers discovered that the higher frequency sound is more broadband than other pump noise. This revelation was confirmed even in the presence of pump harmonics, 1-8 shaft order oscillations, and broadband transient spikes. The research team saw a clear indication that in order to measure pump noise to access how to reduce the noise, in situ methodology is the preferred method measurement process. For future iterations, the in situ methodology will fill the void in experimentally diagnosing and modeling the noise emitted by positive displacement machines that utilize pump casings.

Controlling

CONTAMINATION IN HYDRAULIC EQUIPMENT By Tony Noblit, Market Development Manager, Houghton International Inc.

In today’s world, more demands are being placed on hydraulic equipment and fluid with the trends of higher operating pressure, more compact systems, and the goal of extended hydraulic replacement intervals for components and hydraulic fluids. As a result, contamination control is of the utmost importance. System contamination can come in the forms of solid, liquid, and gas contaminants.

SOLID

LIQUID

GAS (AIR)

This can come from the manufacturer of the assembly of hydraulic equipment. Built-in contamination can be from metal chips from the machining of the components, welding residue, or rubber from cutting and hose assembly. External solid contamination in the form of dust and/or dirt can come from the environment. Contamination can also be introduced externally during maintenance or by adding hydraulic fluid. Many companies often ask: “How clean should the fluid in the hydraulic unit be?" The answer depends upon the hydraulic system itself. The recommendation is to set a target cleanliness for the hydraulic unit. Determine the hydraulic component used on the system that requires the cleanest fluid and set that as the system cleanliness target. For example, the hydraulic unit incorporates a proportional directional valve and the manufacturer of the valve recommends ISO 4406 cleanliness of 17/15/12, and it was established that the proportional directional valve requires the cleanest fluid. Therefore, set the entire system target cleanliness based on the values for the proportional directional valve. Solid contamination can be reduced by filtration. Once the target cleanliness for the system is established, work with your filter supplier to determine the filter that will attain the desired cleanliness and the proper placement of this filter. The key now is to monitor the target cleanliness. A reputable fluid supplier will provide hydraulic fluid analysis, including particle count. The key in particle count analysis is sampling. Be sure the fluid is representative of the fluid in the system. The best place to take a sample for analysis is from the return line ahead of the return line filter. Rinse the sample container two or three times with the fluid to be tested, and obtain a sample from the system while the system is circulating.

The second most common type of contamination is liquid, specifically water. This can be introduced by a heat exchanger leak, contamination from water-containing fluids such as water-dilutable metal removal fluids, or simply humid air. Water in a hydraulic system can cause reduced lubrication, corrosion of hydraulic components, and increased oxidation of the oil. Water contamination in fire-resistant hydraulic fluids is extremely detrimental. Water glycol-type fire-resistant hydraulic fluids (HFC) will reduce the viscosity of the fluid when contaminated with water. Hard water contamination will react with the lubrication additive package formulated in the water glycol fluid and form a white solid material. In estertype fluids (HFDU/HFDR) water contamination can cause hydrolysis. Hydrolysis is the chemical breakdown of a compound due to the reaction with water. This can cause the acid level of an ester to rise, which allows sludge and varnish to form and can corrode the hydraulic components. A reputable fluid supplier will provide an analysis to determine water contamination and other fluid conditions.

Contamination in the form of gas (air) can enter the system from a seal leak on the suction side of the pump. Improperly designed reservoirs, such as a lack of a baffle or the return line ported above the fluid level can also introduce air into the system. Gaseous (air) contamination can cause foaming of the fluid and pump damage due to cavitation/aeration. To prevent gaseous contamination, be sure pump seals are well maintained and in satisfactory condition in order to prevent the ingress of air. Be sure the reservoirs are properly configured with a baffle and the return line is ported below the fluid level. The reservoir should be properly sized to allow the fluid to rest, release air, and settle particles.

“HEART” of the

Hydraulic

By D onal d C. Krau

controlling contamination and keeping your fluids clean, you can extend the life of all the components in your hydraulic system, working together to complete the task. Installing filtration devices in strategic areas will allow the entire system to operate at peak efficiency. For the purpose of this article, I will focus on an area where there are two schools of thought about placing filtration before the pump.

The most important component in any system is the pump. It is the “heart” of the system. You can view it the same way you look at the human heart. What happens if our hearts stop? All body functions cease to operate. The same applies to the pump. What happens if the pump stops working? All system components cease to operate. Proper filtration is the first step in protecting the entire system’s operation. Here is where philosophies differ: suction filtration. Yes, you should have some suction filtration in place, and no, you shouldn’t. Glad we cleared that up! My preferred school of thought is “Yes!” Pumps are rugged and can take a lot of stress. The issue with protecting the pump is to keep out the bigger particles of contamination so as not to place excessive restriction on it. If you get too restrictive, then your pump will cavitate and you will have serious problems.

SEPTEMBER/OCTOBER 2018

STRAINING THE LINE Let’s look at two terms: 1) filtering and 2) straining. Do these two terms have the same meaning? Well, somewhat. When protecting the pump, I always refer to straining which, industry-wide, refers to approximately 200 mesh (74 micron) and coarser. This is the level at which pumps should be protected. Remember, the first component the fluid is going to pass through is the pump. Knowing the number 1 enemy of any system is contamination, your highest priority should be removing particles that are large enough to damage a pump. There are manufacturers who say there should be no filtration in the suction line, and there are manufacturers who say the opposite. Regardless, all pump manufacturers are concerned if designers, operators, maintenance personnel, and users place too tight of a filtration device in the suction line because it could wreak havoc with their pump. The bottom

line is if the pump goes down, the system goes down. By placing a suction strainer in the suction line, and keeping the level of filtration open enough so as not to cause cavitation, it becomes a win-win situation. Listed below are some good rules of thumb to follow in determining at what level of filtration should different types of pumps be protected. Figuring standard hydraulic fluid (150 SUS viscosity) at standard operating temperature (100°F), the suction line flow rate should never exceed 4 ft/sec. Piston pump • Low pressure: 250–500 psi—149 micron or 100 mesh • High pressure: 1,000–2,000 psi—74 micron or 200 mesh Vane pump • Low pressure: 250–500 psi—238 micron or 60 mesh • High pressure: 1,000–5,000 psi—149 micron or 100 mesh Gear pump • Low pressure: 250–500 psi—595 micron • High pressure: 1,000–3,000 psi—149 micron Keep in mind, these are general rules for typical applications. One thing that’s for certain is there WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

are many different systems with many different applications performing a variety of functions. Always consult a certified filtration specialist if you have any questions or concerns regarding your specific application and equipment.

TO BYPASS OR NOT TO BYPASS The next issue to consider is should the strainers have a bypass? That is, are there ever times that unfiltered fluid should be allowed to pass through the pump? The answer to that question is “Yes!” Especially if your system requires a cold-weather start-up. Before starting your system in the cold, ensure that you have a bypass in place to allow unfiltered fluid to pass through the pump. Start-up is a temporary event, and as long as you set the bypass in cold weather, there should be no harm to the pump. Trying to start it in the cold weather without a bypass may cause the pump to cavitate, creating larger problems. Another option for cold weather start-up is to oversize the strainer, which offers more surface area for filtration. This will reduce the pressure drop caused by restricted flow. You may even consider using a coarser filter (larger openings) than what is generally used. Take a look at each application’s total operation. Most suction strainers are available either with or without the bypass option. Some modifications may also be made when using more viscous fluids.

What if you are still not sure what level of filtration to place in your suction line? You can contact a filtration specialist, as mentioned earlier, and keep these rules of thumb handy for reference. Remember to always consider collectively what type of pump is being used, the viscosity of the fluid, the flow rate, the system pressure, and the line size in your selection. The suction line is never a place for filtering (a term generally used for anything finer than 74 micron). Instead, it is normally a place for straining (coarser than 74 micron). Make sure your strainer is sized properly for the application. Suction strainers are not meant to be a system’s only defense against contamination. I have yet to hear a valid reason for not using suction strainers, provided they are installed properly. Filtration also needs to be installed in the pressure line and the return line. And don’t forget the filler-breather port or tank breather, because airborne particles carry destructive contaminants, too. It is also a wise decision to use a portable filtration device, like a filter cart, to clean and polish the fluid in

the system at scheduled intervals. If your pump manufacturer requires a certain level of filtration to protect the pump in order to maintain its warranty, by all means, follow their instructions.

THE BEST DEFENSE A familiar concept known to many is reactive maintenance. This is when you fix a problem only after noticing something has gone terribly wrong, but it is always best to remain one step ahead in servicing and maintaining your system at all times. My philosophy is if you don’t have time to do it right the first time, how are you ever going to find the time to fix it when it breaks? Take a proactive approach to ensure your hydraulic system’s proper operation and longevity. This includes careful system design, regular monitoring, fluid analysis, and preventive maintenance. Suction strainers serve one purpose and one purpose only: to protect the pump. A suction strainer is an inexpensive and effective investment that will safeguard the “heart” of your hydraulic system, and in doing so, prolong its life.

DEMYSTIFYING

CHEMICAL COMPATIBILITY OF SEALS AND FLUIDS By Lucy Heyduk, Material Development Specialist, and Tim McCulfor, Material Development Manager, Trelleborg Sealing Solutions

The chemical compatibility of a seal with fluids in a system is critical to obtaining a reliable, long-lasting seal. Unfortunately, the selection process can be extremely challenging, especially if based solely on chemical compatibility charts. Reactions between the polymers used in seals and the chemicals in fluids vary greatly. For example, certain chemicals “attack” polymers, breaking chemical bonds and degrading the polymers’ properties. In some cases, chemicals extract ingredients from the polymer, leaving it weak and/or lacking important functional properties. Other chemicals can permeate a polymer and cause swelling. This can be both an advantage and a disadvantage, further complicating seal specification. In all cases, it’s important to understand the effect chemicals have on seals and to choose a material that’s compatible with the chemical to be sealed. HERE ARE SOME CONSIDERATIONS FOR CHOOSING THE RIGHT MATERIAL FOR A GIVEN CHEMICAL SEALING APPLICATION: ELASTOMERS The broadest classification of polymers is between elastomers and plastics. We’ll first look at elastomers, which can be thermoplastic or thermoset.

SEPTEMBER/OCTOBER 2018

Thermoplastics are able to be re-melted after polymerization, so they are molded with a melt-processing operation such as injection molding of extrusion. Thermosets react or crosslink during molding, so they are usually compression molded or extruded. Elastomers are characterized by their elastic properties. With some exceptions, they are generally very resilient and excellent for seals that will come into contact with fluids. However, some elastomers are particularly prone to swelling (the fluid is absorbed by the material by diffusion), and others are prone to shrinkage (plasticizers and additives dissolve in the media and are extracted from the material). All these variables make the selection process quite complex, so you should work with an expert polymer or seal supplier to identify the optimum material for a given application. In general, the interaction between elastomer and chemicals follows the rule that like dissolves like. For example, most polar polymers dissolve in polar solvents and rarely dissolve in non-polar solvents (and vice versa). Thus, EPDM-based seals are not recommended for sealing in a system designed to hold a petroleum-based product (both are non-polar) where high swell is expected. Conversely, an EPDM seal is well suited for sealing a system involving water, which is polar.

Commonly applied in fluid power systems, as well as oil and gas applications, automotive manufacturing, and medical devices, EPDM seals are ideal for challenging applications. In fact, EPDM compounds are very useful for the oil and gas and related markets, as they provide outstanding resistance to high-temperature steam. The degree of swelling can be predicted using solubility parameters. If the sealed fluid has a solubility parameter close to that of the elastomer, the attraction will be high, resulting in swelling. The degree of swell decreases when the differential between the solubility of the elastomer and the surrounding media increases. The seal swells due to a diffusion gradient that is produced between the inside of the elastomer and the fluid outside. These define the elastomer’s rate and absolute swell. The absolute swell is defined as the amount of swell that occurs against time for a particular situation. No matter how thick the elastomer, it should never swell more than this particular amount within a specified timeframe. During specific tests, swell can be calculated, and in certain applications, a degree of swelling can be an advantage to the sealing function. This is a specialist area of seal specification, and such applications should be reviewed with an elastomer or seal supplier with a full understanding of this process and the compounds involved.

WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

SOME ELASTOMER TYPES COMMONLY USED IN SEALS AND THEIR CHEMICAL COMPATIBILITY BEHAVIOR: EPM/EPDM. A non-polar synthetic polymer, Ethylene-Propylene Rubber (EPM) is a copolymer of ethylene and propylene; Ethylene Propylene Diene Rubber (EPDM) denotes a terpolymer of ethylene, propylene, and non-conjugated diene. RECOMMENDED FOR:  Hot water and steam Brake fluids Alkalis and acids Ketones and alcohols Sunlight and ozone

NOT RECOMMENDED FOR: Petroleum oils Mineral oils Fuels

The chemical interaction between elastomer compound and media is called chemical attack. There are large numbers of chemical species that can degrade elastomers. The severity depends on the agent and the chemistry of the elastomer being attacked. The degradation may occur by the fluid attacking the polymer backbone itself (e.g., braking or forming additional cross-link or unsaturation) or by interaction with compounding ingredients (e.g., oxidation of fillers). The chemical attack will manifest itself by loss of mechanical properties, hardening, and surface degradation.

PLASTICS Plastics can also be thermoplastic or thermoset. Generally speaking, they are more rigid than elastomers, but their behavior can range from very ductile to brittle, and their chemical resistance varies greatly. The following are some plastics used in seals with descriptions of their chemical compatibility behavior. They all have good compatibility with water and oils. PTFE. Polytetrafluoroethylene (PTFE) has resistance to virtually all media. There are only a few chemicals in extreme conditions that can attack PTFE, including molten alkali

NBR. Nitrile Rubber (NBR) is considered the workhorse of the rubber industry. The acrylonitrile content (ranging from 18% to 50%) determines the elastomer’s fluid resistance. RECOMMENDED FOR:  Aliphatic and aromatic hydrocarbons Oils Gasoline Greases Hydraulic fluids

NOT RECOMMENDED FOR: Chlorinated hydrocarbons Ketones and esters

HNBR. Obtained by either partial or complete hydrogenation of acrylonitrile-butadiene rubber, the generic name for this substance is Hydrogenated Nitrile Rubber (HNBR). The main difference between HNBR and NBR is the highly saturated backbone that results in an improvement in resistance to heat and chemical attack. RECOMMENDED FOR:  Hot water and steam Oils and fuels

NOT RECOMMENDED FOR: Polar solvents Strong acids Chlorinated hydrocarbons

FKM. The chemical resistance of Fluoroelastomer (FKM) is determined by the fluorine content (ranging from 65% to 70% percent) and the type of monomers used. There are five distinct classes of FKM materials based on the types of monomers used in the polymerization process. RECOMMENDED FOR:  Aliphatic and aromatic

hydrocarbons Gasoline, gasoline/alcohol blends Chlorinated solvents

NOT RECOMMENDED FOR: Ketones Strong bases Amines

FVMQ. Fluorosilicone Rubber (FVMQ) is a modified silicone rubber that has many attributes of silicone rubber, but with improved chemical resistance. RECOMMENDED FOR:  Dilute acids and alkalis Petroleum oils Hydrocarbon fuels

NOT RECOMMENDED FOR: Alcohols Ketones Amines

FFKM. Perfluoroelastomers, sometimes called an elastomeric version of PTFE, are the highest performance group of elastomers. They have a fully fluorinated backbone and the broadest possible chemical resistance. Seals made from FFKM are used in extreme chemical environments like chemical processing and transportation, oil and gas, and semiconductor markets. Some grades are not resistant to steam, and some have reduced amine and base resistance.

metals, gaseous fluorine at high temperatures and pressures, and a few organic halogenated compounds. In addition, PTFE has a wide usable temperature range and low friction, making it a premiere seal material. As PTFE has no elastic capabilities, these types of seals are usually used in conjunction with an elastomer energizer or spring. Ensuring this combination of seal and energizer are fully compatible to system chemicals can be difficult and requires suppliers to have a full understanding of material properties. PEEK. Polyetheretherketone (PEEK) has excellent high-temperature properties and good chemical resistance. PEEK excels in high temperature steam, making it an excellent choice for oil and gas applications. UHMWPE. Ultra-high molecular-weight polyethylene (UHWPE) is extremely tough and has good friction and wear properties. It performs well in water-based fluids and most oils, but can be affected by some aggressive chemicals. FACTORS THAT CAN AFFECT COMPATIBILITY The temperature of the sealing application is an important consideration when choosing a sealing material. Both high and low temperature fluctuations change properties, so the polymer must remain flexible enough to seal at low temperatures while maintaining structural integrity at the highest exposure temperature.

Keep in mind that the temperature can also affect chemical resistance. Chemical activity increases with temperature, so a seal material that is compatible with a chemical at room temperature may be attacked at higher temperature. In a dynamic seal, frictional heat generation can cause the actual temperature at the seal interface to be higher than the bulk fluid temperature, so this can be an important consideration. Some seal applications have continuous contact with chemicals and others have only intermittent contact. Chemical attack is a time-dependent process—some materials can resist chemicals when exposed for a short time, but are not recommended for long-term exposure. CHEMICAL COMPATIBILITY CHARTS Chemical compatibility charts are useful to determine the generic susceptibility of general classes of polymers with certain chemicals. They are usually compiled from property-change data of test specimens immersed in the specific chemical. The testing may be done at different temperatures, but most charts just list results from room-temperature exposure. Thus, this information can help manufacturers rule out materials that are clearly incompatible, but determining the compatibility of a specific material-chemical pair for an application requires more research. In addition, compounds within a type can be engineered to resist chemicals specific to

an industry application. Although a type of material may, in general, not work well with a particular chemical, an engineered grade may. Working closely with an experienced seal supplier is perhaps the best way to ensure specification of a fully compatible polymer. The supplier will be familiar with their particular materials, have tested them for resistance, and have experience applying these materials in specific applications. Look for a seal supplier that fully understands the complexities of combining polymers with fluids. Ideally, the supplier will have experience using a specific polymer in the application you are working on so they can discern exactly how it will behave in that system.

Much attention is given to these critical filter the system is by filtering the air passing through the filler breather into the reservoir. Many filler breathers feature an integral air filter element choices, but placing focus on the prevention of contaminant ingression installed into the cap (Figure 1). into the hydraulic system is also important. Filler breathers provide multiple means of reducing contaminant ingression, which is a key to maintaining the ISO cleanliness codes required for the long-term health of a hydraulic system. Filler breathers are present on nearly every hydraulically operated Open cell foam is the most common choice of air filter media. Filtrasystem. As their name states, filler breathers serve the critical dual function levels of open cell foam range from 40 micron in lower cost versions tions of providing a fill location for filling and topping off the fluid and down to 10 micron nominal for many applications. This foam filter acting as a tank breather device, allowing air to flow in and out of the material is often chosen for its long operational life and air filtration reservoir. However, a wide array of options exists to tailor filler breathers properties while still maintaining low airflow restriction. It is worth to meet the unique requirements of a given hydraulic system. Often noting that other media types are also available, including phenolic cellulose, for improved particulate removal that Figure 1: Filler can provide air free of particulate down to 1 micron at up breathers that to 99% removal efficiency. feature an integral Another type of even more specialized filler breather foregoes the internal filter material and instead incorporates a air filter element installed into the cap mounting location for either direct or remote mounting of a spin-on filter. combine compact Spin-on filter filler breathers allow for greater media area, size with a good increased contaminant capacity, and the ability to replace ability to maintain the filter media without replacement of the cap assembly. air exchange rates These specialized filler breathers are well suited for heavily and filtration levels contaminated environments with high levels of particulate required by most in the surrounding air.

It is important to consider the operational environment, space constraints, system cleanliness level requirements, and other filtration within the system when selecting a filler breather.

Valves Control Air Flow and Contaminant Ingression

Figure 2: Common filler breather configuration vs the specialized spin-on mount. The spin-on filters used on these filler breathers are often the same units applied to hydraulic return line filtration.

Filler Breathers as a Fluid Fill Location Serving as a fluid fill location is another important function of filler breathers. When adding fluid to a hydraulic reservoir, many opportunities exist to introduce contaminant into the system. The fluid being added to the reservoir may contain contaminant that was introduced during transport or storage. In addition, some hydraulic systems operate in dirty environments where any number of contaminants can collect on the reservoir surface and around the filler breather. Most mobile applications suffer from variable operating conditions and are particularly susceptible to intrusion during filling. If care is not taken, these contaminants can fall into the reservoir when the cap is removed, or if an operator neglects to replace the cap. Many filler breathers have baskets that provide a basic level of protection by both filtering the oil being added and catching contaminant that may fall into the filler opening when the cap is removed. When selecting a basket for a given application it is important to consider the strainer material, filtration level, fluid viscosity and anticipated fill rate. Low cost versions of these baskets are made of plastic while more robust versions use expanded metal or perforated steel baskets with various length options generally ranging from 4 to 12 inches long. These materials provide a very coarse filtration level removing only large, macroscopic contaminant. Stainless steel wire mesh liners may be added into the perforated steel baskets to improve filtration levels down to 75 micron. Baskets that provide better filtration levels also are more restrictive to flow, often requiring a longer basket to accommodate the same fluid fill rates as a shorter basket with a lower degree of filtration.

WWW.IFPS.ORG • WWW.FLUIDPOWERJOURNAL.COM

The third method to reduce contaminant ingression does not involve filtration, but rather valves. Filler breathers without airflow valves allow uncontrolled venting 24 hours a day, even if the system is not in operation. This allows for an even greater opportunity for both particulate and moisture ingression into the system. A pressure/vacuum valve (Figure 3) located in some filler breather caps serves multiple functions including controlling the airflow and the contaminants it carries into the reservoir. A pressure/vacuum valve only allows air to pass into the reservoir as the reservoir oil level is dropping, for example, when cylinders are extended. When the oil level is constant, the valve remains closed, thereby blocking virtually all contaminant during that time. As oil levels in the reservoir rise during transient operations, the pressure/ vacuum valve holds pressure in the reservoir, which also helps to limit unnecessary venting and contaminant ingression. This valve also serves the important role of maintaining positive pressure at the pump inlet and reducing the likelihood of pump cavitation. The three modes of preventing contaminant ingression (oil filtration, air filtration, and air flow control) are important and often overlooked benefits of selecting a high-feature and high-quality filler breather. Selecting a filler breather that includes these features matched specifically to the system, as well as its operating environment ensures long-term improved system performance with less downtime.

MCCORMICK PLACE • CHICAGO, IL

The largest manufacturing exposition and technology conference is taking over McCormick Place in Chicago, Illinois, starting Monday, September 10 through Saturday, September 15. One of the most highly anticipated trade shows in the industry, the International Manufacturing Technology Show (IMTS) will feature more than 2,400 companies exhibiting from 117 countries.

SEPTEMBER/OCTOBER 2018

The trade show’s sponsor, the Association For Manufacturing Technology (AMT), played host to the third largest number of registrations at the McCormick Place complex in 2016, and they hope to top that number this year. If successful, this will be made possible by the conference organizers, who are dividing the exhibitors into pavilions curated based on industry, technologies and solutions. The configuration will help facilitate better networking and increase the dissemination of ideas across a variety of perspectives in each area of focus. Attendees will not only get to listen and learn, but also share, explore and collaborate. IMTS attractions are another reason why thousands of manufacturing industry professionals attend this biannual event. From AMT’s Emerging Technology Center to the Miles for Manufacturing 5K, the conference endorses exercising the body as well as the mind while sharing ideas and insights with a cavalcade of exhibitors over the six-day event. The largest conference dedicated to global manufacturing technology in the Western Hemisphere, IMTS is determined to have every participant leave with more insight in what is working, what isn’t working and what’s to come. One of the most anticipated attractions of the 2018 IMTS expo is the Smartforce Student Summit, a program designed to engage students and teachers from elementary to post-secondary school with potential career ideas and a look inside the manufacturing technology industry. New advanced technology showcases, learning labs, and hands-on challenges are designed to spark the next generation of makers in robotics, generative design, Industrial Internet of Things, and much more.

COMPRESSED AIR SYSTEMS: THE MATHEMATICS OF EFFICIENCY By Ron Marshall

% Power

You may wonder why people say compressed air is the most expensive and inefficient utility in a facility. By doing some research and looking at simple ratios, it is easy to find out why. Let’s consider an air tool that outputs one horsepower to a device connected to its shaft. If you look at the manufacturer’s specifications you might find that the tool will consume about 25 cfm of air at an output of one horsepower. Since a typical air-cooled screw compressor consumes about 20 kW for every 100 cfm, this 25 cfm will consume about 5 kW. This is the equivalent to range from 6 to 7 hp of air compressor capacity while running at 100 psi. This shows the conversion efficiency of the compressed air medium. The air compressor consumes about 6.5 times as much power than is delivered at the tool. But the calculations don’t stop there. The conversion efficiency just discussed is for a

Let’s assume pressed air system rather than wasting valuable an average loading of 40%, we can see from and expensive compressed air through excessive purge. Figure 1 that with a typical storage receiver size of one gallon per cfm compressor output, the compressor consumes 80% of its nameplate power while outputting only 40% of its air, twice its full load power ratio. This makes the conversion efficiency 13:1. And regarding leaks, often a typical facility will have leakage rates from 20 to 30% of all the compressed air produced. For this example, let’s use 25%. This means you must make and pay for extra compressed air to feed the air tool, costing about 25% more power. The conversion ratio is now 16:1. As pressure drops in the system, air dryers, filters, piping, connectors, and hoses adds up to a typical 20 psi pressure loss. With compressed air at about 100 psi, this extra pressure costs about 10% more than the original lossless system we originally considered. And the higher pressure causes the leakage in the system to consume about 18% more air. The conversion efficiency is now up to 18:1 What does all this mean? Instead of consuming from 6 to 7 hp to deliver one horsepower of power to the air tool, a typical system might actually cost from 18 to 20 hp to deliver one horsepower at the shaft of an air motor. This is why compressed air is called a costly utility.

WHAT CAN BE DONE TO IMPROVE THINGS? HERE ARE A FEW TIPS: • Consider using direct drive electric tools where ergonomics and safety allow. This is especially important for tools that run all the time, with many operating hours per day. • Properly maintain your air tools. Internal wear causes internal leakages that can greatly increase the air consumption and decrease the power output. If your tool needs to be lubricated, make sure your personnel know how to do this. • Choose more efficient air compressor types, if you must run a screw compressor, often the best choice is one that runs in start/stop duty or uses a variable speed drive to control the output. This gives much better conversion efficiency than a load/unload unit with small storage. • Reduce pressure losses by properly sizing compressed air piping, oversizing filters, dryers, regulators, air fittings, hoses and connectors. After doing this, reduce the discharge pressure of the compressor to save power. • Fix your leaks by maintaining a leakage detection and repair program in your facility. A properly maintained system will have leakage CIRCLE 423

10th Anniversary of Action Challenge Finishes Strong Thanks to Members, Education Partners With the support of our membership and education partners, the Fluid Power Action Challenge event introduced almost 2,000 students to fluid power technology in 2018 and its tenth year of operation. The origin of the Action Challenge began with Steve Rogers of Mechanical Kits LTD. In an interview with Steve, he told me about his background teaching high school science, math, and technology before moving on to work as a Senior Lecturer at the University of Nottingham and a Senior Curriculum Officer in the UK. With his experience in education he realized that, “students learned and understood conceptual knowledge at a deeper, more meaningful level when they used their hands as well as their heads to learn.” When his family moved to Toronto, he started his own business to “support STEM (science, technology, engineering and math) education in North America, an opportunity to continue to develop learning materials consistent with my hands-on philosophy.” Soon after, he was approached by the Canadian Fluid Power Association to develop a Fluid Power Challenge for middle school students in 2005. In 2008, NFPA’s President and CEO Eric Lanke became aware of the event and partnered with Steve Rogers and MSOE’s Tom Wanke to pilot a successful challenge in Milwaukee’s suburbs. “NFPA’s mission is to strengthen the fluid power industry,” Eric Lanke said. “Workforce development remains the most challenging issue that our member companies face. Accordingly, NFPA’s efforts drive programs that support a pathway that increases the number of educated fluid power technicians and engineers. Action Challenge events, organized and sponsored by our members and education partners, provide a platform

for our country’s youth to learn about fluid power for the first time while developing an increasingly important skill set. Notably, it also allows for our member companies to connect directly and create long-lasting relationships with the school systems in their communities that produce the next generation of students with potential to elevate the fluid power industry.” NFPA embraced the events and began engaging the membership in the activities. The Action Challenge requires students to design and build a fluid power device that solves an engineering problem. The scenario changes annually. Event organizers connect twice per year to discuss accomplishments, opportunities, and the modifications necessary to improve the next year’s program and provide the best resources for students. “Two thousand students participated in fluid power challenges,” Steve Rogers said. “Their experiences informed them of the fundamentals of fluid power through ‘hands-on’ learning and gave them insight into possible high school courses in STEM education, as well as career possibilities in the fluid power industry. It’s a great project and owes a good deal of its success to its design, the many NFPA sponsors, and staff of NFPA.” Thank you to NFPA members for your support of the Fluid Power Action Challenge and for presenting the opportunity for students to learn outside of their textbooks. Thank you for helping students relate realworld skills to their coursework, for creating awareness about fluid power technology and the industry, and for demonstrating to students and educational systems that fluid power provides rewarding careers.

NFPA CONTINUES ENDORSEMENT OF MANUFACTURING DAY 2018 The National Fluid Power Association recently registered for the second year in a row to endorse Manufacturing Day℠ (MFG Day), which this year will take place Friday, October 5. MFG Day is a celebration of modern manufacturing through nationwide events for schools and the public at local manufacturing companies meant to inspire the next generation of manufacturers. Many NFPA members participate in the annual celebration. NFPA supports events like these both through our own programs and by promoting programs that align with our objectives, like MFG Day. “NFPA member companies report that workforce development is ranked highest among the industry’s challenges,” said Eric Lanke, NFPA President and CEO. “As a result, one of NFPA’s primary strategic priorities is growing the fluid power workforce. Initiatives like Manufacturing Day demonstrate to students the benefits of choosing careers in the industry. MFG Day allows students to witness the same positive company cultures that advocate for creation, innovation, and aptitude that I see when I visit our members’ facilities.” Traditionally, MFG Day has consisted of facility tours. However, NFPA’s Student Career Connections program allows for other options as well, including: Employee Q&A: Engineers explaining to students what “a day in the life” is like, how they got into the industry, etc. Team Project: Engineers work with students to help assemble a fluid power classroom kit. By engaging in this program, members can share their expertise with students, promote their companies and career opportunities to the local community, and make meaningful connections with educators. NFPA members interested in getting involved with any of these options or with their own ideas for a MFG Day event should contact Stephanie Scaccianoce at sscaccianoce@nfpa.com. CIRCLE 427

ISO STANDARDS AWARENESS FOR FLUID POWER PROFESSIONALS

REVISIONS TO ISO 11171: A calibration of automatic particle counters for hydraulic fluid power liquids By Barry Verdegan, Ph.D., Research Fellow, Cummins Filtration Inc. and ISO/TC 131/SC 6 chairman

Hydraulic fluid cleanliness is critical to the overall reliability and efficiency of hydraulic systems. The fluid is both a lubricant and a power-transmitting medium. Reliable system performance requires control of the contaminants in the fluid. Liquid automatic particle counters (APC) are used to measure the concentration and size distribution of the contaminant particles in operating systems and to determine the contaminant removal characteristics of filters. Individual APC accuracy is established through calibration. ISO 11171, Hydraulic fluid power – Calibration of automatic particle counters for liquids is a standard calibration procedure for APC that is used for determining particle sizes and counts. The primary particle-sizing calibration is conducted using NIST SRM 2806x suspensions with particle size distribution certified by the United States National Institute of Standards and Technology (NIST) for particle sizes 30 µm(c) and smaller, and using polystyrene latex spheres at larger sizes. ISO 11171 also provides for a secondary calibration method that uses suspensions of NIST RM 8631x or ISO Medium Test Dust conforming to ISO 12103 Part 1, which are independently analysed using an APC calibrated by the primary method. ISO 11171 establishes minimum APC performance specifications, including the APC coefficient of variation (COV) of sample volume, COV of flow rate, resolution, and particle counting accuracy. The operating limits of an APC, including its threshold noise level, coincidence error limit, and flow rate limits are also determined. Since ISO 11171 was adopted in 1999, particle size has been reported in

NEW units of µm(c). In 2016, however, ISO 11171 was modified to also permit reporting size in units of µm(b), referring to the use of SRM 2806b for calibration. The alternative means of reporting particle size and provision for mathematical conversion of µm(b) to µm(c) sizes is a response to a shift in particle size that occurred when SRM 2806b is used for calibration. The size shift is only an artifact of uncertainty in particle size distribution data obtained by SEM, but has significant practical implications for the industry. A revision of ISO 11171 is currently underway by Technical Committee ISO/TC 131 Fluid power systems, SC 6, Contamination control to address these practical concerns. Changes being considered in the revision include:

In parallel with the revision, an international interlaboratory test is being conducted to determine repeatability and reproducibility using ISO 11171 to generate data to be used by NIST, to certify SRM 2806d as a consensus standard, and to generate data used to verify the counting accuracy. The round robin has been delayed because primary candidate material for SRM 2806d is not yet available. The testing will begin as soon as candidate material meeting NIST specifications becomes available.

NEW PROBLEM

Injection Molding Machine Not Up To Speed

LOAD SENSE SET TO 400 PSI

I was asked to help a student of ours with an injection molding machine that had trouble with the Extruder/ Injection unit motor running slow. They originally were able to get the speeds needed to shoot a good product. I was told the products they were running the past 3 to 4 months ran well, but they used a lower extruder motor speed. They tried to run a different product (which ran well on this machine in the past) that required a higher injector speed. However, when they programmed in a higher speed, the machine would not deliver the higher speed even though the throttle valve was wide open. They replaced the radial piston motor with a new one and checked the case drain flow on the relatively new pump. They also planned to order a new proportional throttle valve. While inspecting the hydraulic system, we noticed 400 TO they had replaced the pump at some time in the past 2000 PSI because the entire system had slowed down, which fixed the problem as far as they knew. Any idea why they could not get the higher speeds?

Solution to Previous Problem

ROTATING STAGE’S HYDRAULIC MOTOR KEEPS LEAKING SOLUTION

A large number, more that 50% would be my guess, of all Geroler type motor do not use a case drain. Typically, the output port of the motors goes back to tank with little back pressure. The case drainage leaks into this low-pressure port and keeps the case pressure at a low level greatly reducing the wear on the shaft seals. The regenerative spool and meter out flow controls require an external case drain since both ports see high pressure at the same time. VISIT FLUIDPOWERJOURNAL.COM TO VIEW PREVIOUS PROBLEMS.

TAILORING COMPREHENSIVE

TO MEET YOUR NEEDS By Peter Skoog, Technical Manager Fluid Power and Grease, Quaker Chemical Corporation

The primary functions of a hydraulic fluid are to: 1. Transmit force 2. Lubricate moving parts 3. Dissipate heat (cool moving parts and other components) 4. Seal clearances between parts

Solid contamination interferes with the first three functions. First, it interferes with power transmission by blocking or plugging small orifices in pressure relief valves and flow control valves. Second, solid contamination can alter the cooling process by plugging heat exchangers and by building up in the reservoir. Both of these conditions reduce the heat transfer needed to give maximum system performance and fluid lifetime. Most importantly, solid contaminants have a negative effect on the lubricating properties of the hydraulic fluid. Solid contamination comes from different-sized particles. Very fine particles (silt) that are smaller than the components mechanical

clearances can collect in fine tolerances and block the flow of hydraulic fluid into the small spaces between moving parts. This physically limits the amount of lubrication going to a specific component. Silting can also limit the movement of components like valve spools. Larger contaminants – particles that are roughly the size of the mechanical clearances in a piece of machinery – cause the most damage in a hydraulic system. These particles cause abrasive wear and tear across the moving surfaces in a component. This damage increases internal leakage, lowers system efficiency, and generates heat. The higher the system pressure, the more problematic abrasive wear becomes. Large, solid particles cannot work their way into fine clearances to cause abrasive wear, but do present problems. These particles can block lubricant flow between moving parts. They also tend to jam pumps valves and motors. These conditions all highlight the need for good filtration (contamination control) in a hydraulic system. When selecting a filter or replacement element, it is important to address the following questions:

What type of oil are you filtering? Where will the filter be located? What is the required cleanliness level of that specific system? Are there existing problems that need to be addressed? Mineral oil is far and away the most widely used hydraulic medium. One can easily find information on the filtration, care and maintenance of this type of fluid. The following discussion will be limited to specialty fluid like fire-resistant hydraulic fluids and bio-based or biodegradable fluids.

ANHYDROUS (WATER-FREE) FLUIDS Anhydrous fluids (HFD-U), whether they are synthetic or based on a naturally occurring base stock, can be treated very much like mineral oil when selecting filter media. Synthetic, as well as cellulosic media, can be used with these fluids. However, because the fluids are synthetic and will vary in chemical composition, it will be necessary to check the compatibility of the filter

WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

medium, seals, and adhesives used in the filter element with the fluid that has been selected. Both the filter manufacturer and fluid supplier should be able to provide guidance in the fluid selection process. Water-free fluids are normally used in high pressure or high-heat environments. These severe operating conditions will require fine filtration. The chart to the right offers some guidance: Attaining high fluid cleanliness requires a plan. Simply putting fine filters with high beta ratings (β • 1,000) in a system may not produce the desired results as filter consumption might be excessive. Sometimes staged filtration – using finer and finer filter elements – may be required. Filtering fluid from its shipping container into the reservoir will aid in meeting a cleanliness objective. A side benefit of instituting a filtration program is increased fluid life. Wear debris particles have a high surface area and can act as catalysts in fluid degradation. Removing wear debris slows the chemical breakdown of synthetic and natural hydraulic base stocks.

sludge formation and bacterial growth so filtration is less problematic. As with water glycol fluids, filter media must be compatible with alkaline water solutions.

CONCLUSION A comprehensive filtration program can be tailored to meet the needs of any fluid and will fit all operational environments. Hydraulic fluid filtration offers equipment owners and users an opportunity to extend component life, increase production time, and reduce costs.

WATER-BASED FLUIDS Water glycol hydraulic fluids (HFC) are the most widely used and well-known water-based hydraulic fluids. These fluids are true solutions composed of soft or deionized water, a polyglycol thickener, glycol, and an amine-based additive package. Being a true solution, it is virtually impossible to remove major fluid components and additives with standard filtration. Water glycol fluids can be filtered down to 3 microns absolute (β3 > 1000) without damaging the fluid. Because HFC fluids rely on an alkaline pH (water glycols typically have a pH > 9.0) to inhibit rust, filter media must be compatible with alkaline water solutions. Synthetic media like fiberglass is preferred. If cellulosic media (paper) is used, it has to be resin impregnated to fix the filter’s pore size. Untreated cellulose or paper filter media will swell in the presence of water. The swelling shrinks the pore size and may give the indication that the filter is plugged when, in fact, the filter media is not compatible with the hydraulic fluid. High water content fluids (HFA) can be classified as either soluble oils and micro emulsions (HFA-E) or water dilutable synthetics (HFA-S). The effects of filtration on these two different fluid types can be drastic. The classic mineral oil containing fluids (HFA-E) have a tendency to coagulate wear, dirt or ingress particles to form a greasy cake of particles. These fluids also have a tendency to grow bacteria and build up greasy lumps resulting from interaction with water hardness. In coal mining, the oil present in the emulsion tends to absorb coal dust, which can result in dispersed masses or sludge that is difficult to filter. This can present issues for a coal mining operation where the requirements for fluid cleanliness are increasing, and improper filtration can corrode and plug filters, as well as shorten the expected lifetime for valves and cylinders.

CYNTHIA ESHER RETIRES FROM MCAA The Measurement, Control & Automation Association (MCAA) announced the retirement of Cynthia Esher on June 30, 2018, after 40 years of service. Esher has been involved with the MCAA or its predecessor organization, the Scientific Apparatus Makers Association, since 1978, and was named president of the MCAA after the organization’s name change in 1994. Esher was instrumental in moving the MCAA away from writing standards and changing the dues structure, which doubled the size of membership for the organization during her tenure. Teresa Sebring has succeeded her as MCAA president. www.themcaa.org
