If your experience is at all like mine, you entered your first fluid power job with little experience and understanding of hydraulics or pneumatics. Scarcer yet was an understanding of fluid power system design. Fortunately for me, I landed a job early in my career with a company that provided IFPS training and encouraged employees to get certified. Looking back now, I see clearly the value of those early training classes and fluid power certification. At my first job, I was eager to learn but most of my training was on the job. This training consisted of troubleshooting hydraulic issues on the manufacturing floor and hoping I could turn the right knob or move the right hoses to get the desired outcome. Frustration would often set in, but I did get a lot of handson experience with hydraulics. At my next job, certification training gave me an opportunity to gain an understanding of hydraulics and hydraulic systems. I learned how to read hydraulic schematics, troubleshoot systems, and perform preventative maintenance. This gave me the confidence to work with employees on the plant floor as well as customers needing help in the field. The other thing it gave me was a path to develop my skills. I got my first certification as a mobile hydraulic mechanic. Next, I successfully completed mobile hydraulic technician and specialist certifications. Now, years later as I take the reins as 2018 President of the IFPS, I believe we have a stronger message than ever to get out into the industry. I have long thought that fluid power training and certification offer a competitive advantage for individuals as well as companies. For individuals seeking a new job opportunity or promotion at their current company, fluid power certification shows a commitment to professional development, as well as demonstrating knowledge of the industry. Companies providing IFPS training and certification for employees can expect better quality, safer work environments and improved job satisfaction. As we enter this new year, please join me in promoting the IFPS by sharing your story about the value of fluid power training and certification. Engage in conversations with colleagues and share on social media. If you haven’t already, add your certification(s) to your LinkedIn account, your business card and your e-mail salutation. Finally, I invite you to get involved by joining a committee or joining us for one of our meetings this year. Together we can make a difference.

Much time is often spent looking for leaks and finding inappropriate end uses in an industrial plant in an effort to save money. But often overlooked is a key compressed air consumption right inside the compressor room itself. Desiccant air dryers can consume a surprisingly large percentage of the total air compressor output.


This malfunctioning air dryer eats 75% of the compressor output.


The compressed air coming out of an air compressor is normally 100 percent saturated with water vapor and is typically produced at significantly higher temperature than ambient conditions. If this air is allowed to cool in the plant piping, the water will condense out of the air, forming free water, which mixes with rust, scale, oil and dust in the pipes to form a sticky sludge that will ruin compressed-air tools and clog the pneumatic circuitry of compressed-air-operated production machines. Some sort of air dryer is needed to remove the moisture and reduce the dew point of the air well below ambient conditions. The most common style of dryer used for this purpose is the refrigerated type, which cools the air, separates its moisture and produces dew points of about 35 degrees F. But sometimes there is a need for instrument-quality air, or air that can be used outside in freezing conditions. If this is the case, the refrigerated dried air is unacceptable. A desiccant style dryer must be used.


Desiccant dryers use a material, most commonly activated alumina, to strip the moisture from the compressed air through an adsorption process, most commonly producing compressed air that is in the minus 40 degree range. When activated alumina is pressurized, it removes the water from the flow of compressed air until the material becomes totally saturated. The most common way to regenerate the desiccant material, removing this moisture, is to depressurize it to near atmospheric pressure and pass very dry compressed air through it. Once this is done the desiccant returns to a ready state for more drying. Obviously this cannot be done without disturbing the flow of compressed air through the dryer, so heatless desiccant dryers are designed to dry with one vessel filled with desiccant while regenerating another twin vessel. The dryer switches from one tower to the other every 10 minutes, alternately using each tower to dry and then regenerate. This regeneration takes between 15 and 20 percent of the dryer rated flow on a dryer operating with a fixed timer cycle. The purge is released through a muffler and is lost to atmosphere.


The last sentence is important: The regeneration purge takes 15 to 20 percent of the rated flow of the dryer. This means if the dryer is partially loaded, or much larger than the running compressor, the percentage of the purge flow compared to the actual compressed air flow produced by the compressor can be much higher than this nominal 15 to 20 percent. For example, if the dryer is only




50% loaded, the real percentage of the actual flow becomes 30 to 40 percent of the total. If only 25 percent loaded, then 60 to 80 percent of the total flow can be consumed.


This percentage can be reduced by using energy efficient dryer controls that turn off the dryer purge when not required, if the desiccant is not saturated after a normal timer cycle. A dew point sensor samples the air and only activates the purge flow whenever the dew point reaches a certain trigger level. This can greatly reduce the purge rate percentages and save energy. But these controls are sensitive to oil and water contamination and therefore need maintenance. Often calibration of these controls is not done, basically disabling an important energy savings feature. The dryer in the photograph is an oversized 250 cfm dryer that has a failed control. The 40 cfm purge flow it consumes makes up 75% of all the air the plant compressor produces.


In this case the air dryer has been oversized and is quite a bit larger than the 160 cfm air compressor it is matched with. The dryer was purchased at auction for a very low price, a real sweet deal. The compressor produces compressed air at 25 kW per 100 cfm so the dryer purge is costing about $8,400 per year at 10 cents per kWh, more than the purchase price of the dryer. The actual plant flow is only about 13 cfm, about 5 percent of the capacity of the dryer; therefore, with a working dewpoint control, the purge could be turned down about 90 percent after accounting for the required 15 percent purge flow. The savings for repairing the control (or replacing the dryer with a new one) would be about $7,560 per year. In this case the control repair was estimated to cost $3,000, something the plant maintenance personnel think is quite costly, but if implemented it would make the simple payback on the work about 5 months.

Three Part Series TRANSFORMING FLUID POWER: RETHINKING THE WAY WE APPLY FLUID POWER Presented by Dan Helgerson, CFPAI, Fluid Power Journal Technical Editor One of the most common misunderstandings about fluid power is the relationship between flow and pressure. It is hard to convince someone that increasing the pressure in a system will not increase the speed when the technician just finished increasing the pressure and things are going faster. Learn how thinking differently about flow, pressure, and energy can transform the way we apply fluid power.

hot blasting better protects powertrain components from damage, while increasing their cyclic loading capacity. Automobile manufacturers use shot blasting for metallic components, such as engine, chassis, and transmission parts that are subjected to high levels of stress in later use. For example, during the shot blasting process of shafts and pinions in the automotive industry, small abrasive blasting objects are projected against the surface to be treated at high speeds, using compressed air. This process generates a residual compressive stress, increasing the permanent strength of the material by up to 60 percent.


At the same time, the treatment enhances the material’s bending strength and corrosion resistance and expands its surface (such expansion is important primarily for bonding components).


Pneumatics plays a major role in the process, and, according to Martin Stolte, CTO at V+M Systems GmbH, a company specializing in shot-blasting systems, shorter air lines can provide improved system performance that saves energy. One method of shortening air lines in the industrial robots used for shot blasting is to have the valve positioned near the load. When an automotive manufacturer customer added the AVENTICS AV05 series to its list of approved components, the engineers at V+M Systems were able to integrate pneumatic control of the robot arm directly at the load due to the compact design and the light weight of the valve system from AVENTICS.

Unlike standard valves with a rectangular base plate and mounted valve, in the AVENTICS Advanced Valve (AV) family, the spool is arranged diagonally in the valve housing, reducing the volume of the valve on the base plate by approximately 45 percent. The valves in the AV series are also nearly 40 percent lighter because of high-performance polymers and a specially developed injection molding method.


Mounting the valve directly on the moving robot arm valve had no effect on the robot dimensioning, and, according to Stolte, this positioning resulted in reduced assembly time and costs when piping, lower compressed air consumption for users (thanks to a reduction in dead volumes), and an overall increase in the energy efficiency of the shot-blasting system. The integrated fieldbus connection and the input and output modules from the AVENTICS Advanced Electronic System (AES) can process analog and digital signals. As a result, V+M Systems can incorporate machine diagnostics via the valve system by reading in pressure switches via the integrated digital input module and transferring the machine status to the controller via the fieldbus.

NEXT GENERATION HYDRAULIC FLUIDS: High-Performance & Environmental Safety


By Josh Green, EnBio Industries

Selecting the right hydraulic fluid for an application is not always an easy task for a hydraulic system operator. When the application is ecologically sensitive, the selection becomes even more difficult, especially since there is no uniform set of tests that clearly indicate the fluid’s performance or the ecological effects if the fluid spills or leaks. In addition, there is much misinformation from companies and organizations pushing their own agendas. This often leaves hydraulic system operators to choose between sacrificing the environment for performance, or sacrificing performance for the environment.1


US Environmental Protection Agency (EPA) regulations dictate rules for fluid release, but the language in the regulations is still vague about what separates a real environmentally acceptable lubricant (EAL) and fluids that are just “good enough.” Testing is not always required for a product to be labeled as an EAL, which means there is not necessarily any proof that a fluid (base oil and additives) is any better than the mineral oil product it is trying to replace.2




Since traditional hydraulic fluids have been deemed a hazardous material, any reduction in their environmental footprint is seen as a major step forward. An example of this is the push for bio-based products. Although the base fluid in these products is fully biodegradable and offers several benefits, the base fluid alone will not last long enough to be cost-effective. As a result, the blending done or the additive pack included to increase performance decreases the environmental benefits.3


Fluid performance testing is conducted under ideal conditions, but does not look at how the fluid performs at the end of its usable life. Some products that state they are environmentally acceptable begin to breakdown quickly and performance degrades rapidly thereafter.4 These fluids can also have a large increase in toxicity as they degrade and become contaminated.5 These are just some factors that make users skeptical about the EAL options available on the market.

The next generation of hydraulic fluids must solve the problem of providing high-performance while meeting environmental safety requirements. EnBio Industries has produced a patented polyalkylene glycol (PAG) blend that is a next generation of hydraulic fluid. EnBio lasts twice as long as mineral oil products and three- to four-times longer than bio-based products. It also increases the efficiency of the pumps, thereby improving performance and lowering fuel/energy consumption. EnBio’s high performance is possible due to the following: a high viscosity index (VI) (ensures fluid stability throughout the operational temperature range of the equipment); no shearing (the viscosity will not change throughout the life of the fluid); minimal wear on equipment (over 80% less wear (Vane pump test) compared to leading fluids); no varnishing or creation of sludge within a hydraulic system; and a coefficient of friction roughly half of other fluid options. University testing of EnBio (Texas A&M; Penn State; University of Nevada, Reno: and Edison College) looking at all three environmental factors (toxicity, biodegradation, and bioaccumulation) concluded that EnBio’s formula has near zero impact on the

natural environment when a spill occurs under realistic conditions. Independent testing is needed as not all fluids can be tested in the same manner. For example, tests developed to review chemicals that solubilize in water, such as OECD 203, are meant to understand the effects of the solution on biological material (like fish).6 However, most fluids – like mineral oils – are not water soluble, and with a lower specific gravity actually float to the surface. The test results are false positives because the hydraulic fluid never actually entered the fish’s gills.7 Even among PAGs, EnBio is the only one that passes the biodegradation test OECD 301B across the entire product line.


The hydraulic system operator’s choice of a fluid must not only meet performance requirements and comply with regulations, but must also be cost-effective. Synthetics and environmentally acceptable fluids generally have a higher price than other types of fluids. However, the long-term savings, when key areas are considered, such as the costs of maintenance, wear and tear, equipment lifespan, and equipment replacement, can be highly significant; especially if the potential costs of a spill or leak are factored into the overall cost calculations. EnBio’s performance benefits allow for significant cost saving when compared against other options.


Fluid compatibility – especially with EALs – should always be checked. A small number of materials, such as Buna-S and pure urethane, do not perform well with EnBio. For non-virgin systems, the conversion is also important as PAGs are not miscible with other fluids, except other anhydrous PAGs. EnBio Industries assists customers throughout the conversion process. The EnBio Industries product line allows operators to use a fluid that will promote cost reduction, prevent environmental issues with near zero ecological impact, and increase performance, making EnBio the next generation of hydraulic fluid.

NFPA Members Inspire the Next Generation

Throughout the month of October, NFPA members opened their doors to expand knowledge about and improve general public perception of careers in the industry. Each experience was unique. Companies found it beneficial to establish relationships with educational institutions, and some took it a step further and connected with the local chamber of commerce and elected officials. Here is the variety of ways NFPA members worked to inspire the next generation this October: • Aggressive Hydraulics: Hosted an open house for students and parents to explore fluid power manufacturing and career options. Afterwards, the schools extended an invitation to speak with incoming students each trimester about manufacturing. Congressman Tom Emmer even stopped by for a tour. • Airline Hydraulics: Encouraged the community to come witness the fabrication of complex, engineered systems during their facility tour and greeted about 100 students and teachers.



• Balluff: Welcomed 120 visitors and showed them how sensors and automation work. College admissions reps came to speak to students and parents about various manufacturing degree programs. • Daman: Rotated three tour groups of 30 students and organized a check-in-to-win contest, which added to the day’s activities. • FORCE: Gave area high school students a tour of the facility and an overview of fluid power and its applications. Afterwards, students were challenged to notice where fluid power might be applied on their trip back to school. • Lanxess: Applied a two-pronged approach that included manufacturing site events and a video competition. Participating schools had a chance to win $5,000, $3,000, or $1,500 to buy equipment and supplies for their chemistry or science lab. • Moseys: Hosted 86 local area high school students in California. The company offers tours all year long, as well, for those that couldn’t make it on MFG Day. • Paragon Technologies: Collaborated with the Macomb County Economic Development

committee and educators and administrators, contributing to the county-wide mission of reaching 2,000 students on October 6th. • Woodward: Launched a new tour process where guides use a combination of iPads and video monitors as students make their stops across the manufacturing floor.

Three major government funding initiatives for fluid power research have so far come out of the fluid power industry’s successful partnership with the Center for Compact and Efficient Fluid Power (CCEFP). One is the hydraulic research program for off-highway vehicles at the Department of Energy. The second is the inclusion of soft robotics as a topic of interest in the Emerging Frontiers in Research and Innovation (EFRI) program of the National Science Foundation. And the third is the selection of the Advanced Robotics for Manufacturing (ARM) Institute by the Department of Defense as our nation’s newest Manufacturing USA Institute. With so much going on it’s easy for NFPA members to get lost in the alphabet and federal agency soup. That’s part of why NFPA recently joined ARM as a non-profit, supporting member, and why I recently attended its first member meeting in Pittsburgh. I wanted to learn more about the opportunities for fluid power research in ARM, knowing that something in the neighborhood of $80 million has been allocated for industry-led, university-supported research projects that will help commercialize technologies that support the growth of advanced robotics and automation in U.S. manufacturing. Prof. Eric Barth of Vanderbilt University, a deputy director of the CCEFP with a focus on human-scale fluid power technologies, has been a vocal presence inside of ARM since its initial formation. He has helped ARM realize that fluid power is an essential, and frankly not well-understood, actuation technology for collaborative robots in the manufacturing workplace. In its mission and strategy documents, ARM seems committed to the growth of collaborative robot technology, especially for the small- to medium-sized manufacturing industry; environments that have had a difficult time reaping the advantages of automation because of their relatively low lot sizes. Fluid power, especially with adaptive control systems, could better facilitate the rise of that technology in these spaces, and therefore fluid power represents an area that could receive research funding through ARM. But frankly, that won’t be easy. ARM has just released its first call for project proposals, and their focus will be on projects that help them achieve one of the following key strategic priorities: • Identification and packing of objects • Unloading and unpacking of objects • Transport and delivery through a complex, crowded floor WWW.IFPS.ORG • WWW.FLUIDPOWERJOURNAL.COM

• Inspection of non-standard materials • Tracking and traceability of components • Manipulation of compliant materials: food, textiles, wire harness, composite • Surface treatment: sanding, painting, polishing The good news is that these priorities are application, not technology, based. They are the challenges that ARM’s industry members told them, through a roadmapping process, that they needed the most help with. ARM is now open to technology development proposals that will help them achieve these priorities. That at least doesn’t exclude fluid power from participating. The bad news is that although fluid power hasn’t been excluded, no specific preference for fluid power has been given. What will drive the selection of research projects is the quality of the proposals submitted, and the organizations doing the submitting must be the members of ARM – among which there are currently very few fluid power companies or fluid power-focused universities. At the ARM member meeting, I participated in a number of matchmaking sessions. These were meetings designed to bring potential research partners together for the purpose of formulating initial proposals to ARM. And these discussions were very encouraging. The ARM membership currently consists of a nice mix of manufacturing end-users, automation and robotic technology providers, and academics with relevant skills and lab facilities for the projects. The winning proposals will likely come from exactly such teams – a manufacturer with an automation or robotic challenge, a technology provider willing to take their systems to the next level, and a university partner to help house and advance the project. I was present when one such collaboration came together that included fluid power as one of its essential components. If fluid power is to receive research funding from ARM, the construction of more such collaborations is going to be necessary. Concept papers for ARM’s first project call were due in November, but they expect to be issuing new calls every six months or so. If there are any NFPA members (or University Education Partners) who are interested in helping out, or at least learning more, please contact me at or 414-7783351. Knowing that government support of fluid power research projects is currently our best way of ensuring the sustainability and growth of our industry’s academic infrastructure, I’m happy to play the matchmaker if I possibly can.

More than fifty committee members from all over the world attended. Ten U.S. experts from NFPA member companies that participate on various U.S. Technical Advisory Groups (TAGs), attended on behalf of the U.S. fluid power industry. The remaining delegates traveled from China, Japan, Belgium, Italy, France, Germany, and the United Kingdom. MEETING HIGHLIGHTS The Subcommittee (SC) on connectors is led by chairman Lou Moreiras (U.S.), a consultant for Parker Hannifin. The SC heard updates from each of the Working Group (WG) convenors and approved via resolution to revise the standard on fluid power systems for connectors and associated components having to do with nominal pressures. The committee also approved moving forward on a revision of a standard on the test methods for metallic tube connections in hydraulic fluid power connections. Ted Amling (U.S.) of Parker Hannifin is the convenor of the Working Group for methods of connecting hose fitting and tubes to connectors. The working group revised and published several ISO standards this past year, including standards on hydraulic hose assembly test methods and hose fittings with face seal ends. Work continues on projects revolving around test methods for tube connectors and 24-degree cone connectors. The SC on contamination control is chaired by Barry Verdegan (U.S.) of Cummins Filtration. This SC is focusing on a number of standards that will need revision as a result of a change in a test fluid for the calibration of automatic particle counters for liquids. Two interlaboratory tests are slated to begin in January. The committee also heard a presentation from one of the Chinese experts on regression techniques of automatic particle counters. The group encouraged the expert to begin a new work item proposal to begin the standardization process. In the Working Group on filter and separator evaluation, convenor Bruce Shane (U.S.) of Parker Hannifin led discussions about the protocol for an interlaboratory test on filter multi-pass test under cyclic flow conditions that will be conducted beginning in early 2018. CONTINUING THE DEVELOPMENT PROCESS NFPA members are encouraged to participate in fluid power industry standards development. Whether at the national and/or international level, your engineering expertise is needed • to help influence global technology; • give expert input; • be a part of the U.S. voice in an international arena. Contact Denise Rockhill at to learn how you can get involved.

Enabling a single robot to exchange end effectors during a manufacturing or assembly process, much as a human is capable of operating different tools, increases robot flexibility. When there are a multitude of applications that require tool-changing, automating this process translates into a significant reduction in expensive, non-productive tool-changing time. A case that illustrates the importance of Robotic Tool Changers involves the new, automated design-testing application at Schmalz, a company specializing in vacuum automation and ergonomic handling solutions globally. The first step in automating Schmalz’s proof-of-concept process included installing a large FANUC robot for material handling. Although the robot provided some initial benefits, tools on the robot still had to be changed by hand, and this manual process created downtime.

Box 6479, Fort Worth, TX 76115 V. 817/923-1965






Schmalz needed a tool changer suited both to the size of its 600 kg FANUC robot and the unpredictable loads of its customers’ test material, which could range from featherweight plastic sheets to extremely heavy automotive components. To meet this need, Schmalz added ATI Industrial Automation’s Quick-Change tool changers. Robotic tool changers are designed to function for millions of cycles at rated loads, while helping to maintain extremely high repeatability. An automatic robotic tool changer must possess physical characteristics that are at least equivalent to the robot arm itself. It must hold the tool securely - even if electrical power or the air supply fails. The ATI changer has a master plate mounted on the robot arm and a tool plate attached to the tool. The heart of the locking mechanism is an air-actuated piston on the master plate. The new Robot Test Cell at Schmalz includes one Master and three Tools mounted to different Schmalz Grippers–which can weigh up to 130 lbs. each before product is handled. With this new Robot Test Cell Schmalz can now design and test more custom solutions for its large variety of customers with a very broad variety of different requirements and can evaluate each customer sample more thoroughly in a shorter amount of time. The new test system is in line with the company’s sustainability goals as well since it is contained in a single work cell, and additional tools can be added quite easily to further increase productivity. Integrating the Tool Changer products gave Schmalz the ability to handle the variable payloads of customer material and seamlessly transition between each of the different Grippers in a single test run. If needed, multiple trials can be performed to narrow down and select the best equipment for the job. The Tool Changers have also provided an additional measure of safety by keeping employees out of the robot cell.

Solution to Previous Problem


Meter-out speed controls on single-rod cylinders cause the rod-side cylinder pressures to intensify higher than the cap end, which is normally the maximum pump pressure setting. If the cylinder develops a piston leak, it acts like a regenerative circuit, forcing rod-side oil to the cap end, speeding up the cylinder. We told them to close off the isolation ball valve on the cap end and shift the control valve to retract the cylinder. If it extends, the cylinder is leaking past the piston seals, causing this speed problem. VISIT FLUIDPOWERJOURNAL.COM TO VIEW PREVIOUS PROBLEMS.

Directional Valve Seals Failing I was asked to help inspect a 4" bore, 2" rod cylinder that had a 40" stroke and an 8" stop tube. It had a D05 size mounting pad machined into the blind-end cap of the cylinder with a steel tube connection from the rod cap to the blind-end cap. The cylinder shop had repaired this cylinder about 2 months earlier, and, at that time, the cylinder did not have a valve mounted on the D05 pad, and the customer could not tell them where it was leaking. So, they did a light hone, installed new seals, tested and returned it to the customer only to have it come back again for warranty repair. This time, however, it had a 3-position proportional directional valve mounted on it. The cylinder shop was told, “It leaks,” but again, the customer could not say where. The cylinder shop needed help to understand how to electronically stroke the proportional valve. They connected a pressure and tank line to the cap-end plate, and we connected our portable power supply and command generator, so they could stroke the cylinder electronically with the proportional valve mounted on it. Oil started leaking up through one of the mounting bolt holes when they reached about 200 PSI. They removed the valve and found that one of the O-rings on the valve had extruded and failed. All the mounting bolts were tight, and it looked like an easy fix. However, the cylinder came back again with the same problem 6 weeks later. What do you think is the problem?

This proportional control valve comes in sizes from 16 to 50mm and fits standard ISO 7368 and DIN 24342-cavity porting. Control areas provide 4 millisecond response time and can close the poppet under a high-pressure load. The valve has On Board Electronics. All you need to provide is a 0-10-volt command, which is proportionate to the position of the valve. No additional Amplifier Card is needed. The valve requires a 24-volt supply with a minimal electrical current of 3 amps per valve. It also requires a minimum pilot pressure of 40 psi. If voltage or pressure drops below the minimum requirement, the valve shifts closed to safe mode.


This series is designed as a point of use, two-stage filter that removes moisture and contaminates from tools and equipment. Each model offers a standard 5-Micron rating with lower Micron ratings available. Flow ranges of 15 SCFM to 2000 SCFM and pressure ratings of up to 250 PSI are available. Additional standard features include a built-in differential pressure gauge, which provides a visual indication of required maintenance, and a weep drain that allows for a continual discharge of moisture.




ecause air is a compressible fluid, controlling the speed of actuators is a unique problem. A pressurized air cylinder that is not under load will extend and/or return suddenly if the exhaust air is not controlled. This is often the case and is not likely to cause damage since most air cylinders are engineered with shock pads, or incorporate external stops on the cylinder rod to prevent the piston from bottoming internally against the head and cap ends. Unlike hydraulics, most pneumatic applications require full extension or full retraction without an intermediate position. It is necessary to understand the load dynamics that are present and to calculate the Load Ratio (LR) to achieve accurate speed control. This extra force, beyond the load force requirements, determines how fast the load can accelerate.

Determine the Appropriate Solution to

Control Air Cylinder Speed EQUATION

LR =

Factual • 100 Ftheoretical

LR = Load ratio% Factual = Actual force required to balance load lb. Ftheoretical = Theoretical force produced based on pressure and bore size at cylinder lb.

The load ratio should never exceed approximately 85%. The lower the load ratio, the better the speed control, especially when the load is subject to variations. To get a constant speed, the load ratio should be approximately 75% or less. If accurate speed control is required or load forces vary widely, 60-70% should not be exceeded, perhaps no more than 50% in vertical applications. A positive speed control is obtained by throttling the inlet or exhaust air of the cylinder by means of a speed sontroller, which is a combination of a check valve, to allow free flow towards the cylinder, and an adjustable throttle (needle valve). Metering out is a common method for controlling double acting cylinders. This is not to say that air cannot be metered into a cylinder to control velocity. However, unless a constant restrictive load is being moved, the cylinder will lurch as air pressure builds to the requirement of the load and then the air expands suddenly in the cylinder, dropping the pressure, only to repeat the process and lurch again. In some instances, the cylinder speed can be adversely impacted by the resistance created by the tubing and valving connected to the cylinder. To prevent the restriction of flow from delaying




While increasing the supply pressure may cause the acceleration rate to increase, it is done at a higher energy cost. Acceleration requirements need to be evaluated, and when slower acceleration will work, then slowing the acceleration will save energy costs.

the response time of the cylinder, a quick exhaust valve may be employed. The quick exhaust valve connects directly to the cylinder port and allows for a large volume of air to exit the cylinder quickly to prevent dampened response times. The rpm of air motors, on the other hand, is commonly controlled by the pressure at the inlet. Many air motors power constant loads, so it is as effective to regulate the inlet pressure as it is to provide a restriction at the inlet or outlet that wastes power needlessly. Fig. A illustrates a double-acting cylinder mounted vertically with a load hanging on the cylinder rod. If the flow controls (1.1 & 1.2) were to be reversed for “meter-in” control, the load would drop suddenly when the solenoid valve is signalled to lower the load. “Meter-in” flow control would cause uncontrollable lowering and a hazardous condition. Notice there are flow control valves in each cylinder line of the circuit to control the velocity. Each flow control valve allows air to pass freely in one direction and to be restricted in the other. As the valves are configured in the circuit, shifting the power valve to raise the load allows free flow of air through the check valve to the rod end of the cylinder to lift the load. The flow from the cap end is restricted back through the control

Investigation of Noise Transmission through Pump Casing


PURPOSE The goal of this research is to model the transmission of vibrations from a swash plate type axial piston pump through the pump’s casing to the generation of acoustic noise in the surrounding environment. The desired result of this research is to gain a better understanding of noise generation and transmission in axial piston pumps and to create a comprehensive model of an axial piston pump’s noise emission. This computer- based model can be used for the predictive design of pumps, including pump housing and valve-plate design to reduce airborne noise generation.

PROGRESS Using a generic structural acoustic process, a pump’s oscillatory energy was organized into three domains—hydraulic, vibration, and acoustic—and a task was formulated for each domain. Task 1 (hydraulic) was to measure pressures to validate the current hydraulic model, task 2 (vibration) was to preliminarily perform experimental modal

analysis, and task 3 (acoustic) was to experimentally characterize the sound field using a custom made robot. So far, the experimental results have supported that pump harmonic frequencies below 5,000 Hz are the dominant frequencies of audible noise. To better interpret the spatial distribution of noise, it was decided to minimize the reflection of pressure waves by covering the expose concrete floor in the semi-anechoic chamber. Additionally, a new hemispherical measurement grid was created in order to take advantage of its geometric symmetry that required new robot speed and a taller robot stand. Major improvements were also made to the sound chamber in order to raise the shaft height and improve the acoustic qualities. The modelling method is being revisited, and custom-vibration modelling software is being developed.

NEXT STEPS The remodeling of the sound chamber will be completed, and the experimental modal analysis will continue.

Methods for Stopping a Linear Pneumatic Actuator’s Movement in Mid-stroke By Richard Bullers, SMC, CFPPS


machine operator defeats a guard and reaches his hand into a machine to reset a part in a nest, but misjudges the speed of the press. Does the pneumatic actuator driving the tooling cause a serious injury or were other steps taken to stop the actuator in time? As you can imagine, stopping and holding a pneumatic actuator in mid-stroke can be an important design feature. Application examples include positioning a part in more than one location, preventing a machine crash in the event of a fault, or including a redundant safety function in a machine. If you are unfamiliar with the methods, functional considerations, performance, or safety aspects of stopping and holding a linear pneumatic actuator in mid stroke, this article can serve as a starting point for making the right decisions based upon realistic performance expectations.


“Single acting” cylinders incorporate an internal spring for automatically returning or extending them to a home position and are not used for positioning, but may provide an ancillary function such as driving a shot pin into a lock. Avoid them for positioning, but consider them for complementary functions. A type of double acting actuator that is ideal for stopping in mid-stroke is known as a “locking cylinder”. This type of actuator incorporates an internal mechanical lock to hold the rod in place once cylinder motion has stopped.

Consider the following questions and answers when selecting a linear pneumatic actuator that must be capable of stopping anywhere along the stroke. 1. WHAT TYPE OF LINEAR ACTUATOR SHOULD I USE OR AVOID? Selection of the correct actuator is a critical part of the process. The term actuator encompasses many types of pneumatic drives, including single acting cylinders, double acting cylinders, rotary actuators, air chucks or grippers, and air bellows. The focus of this article is on double acting cylinders where air is supplied and controlled to both sides of an internal piston. Actuators that have inherent leakage due their construction are avoided. Leakage makes it virtually impossible for an actuator to hold a specific position after it has been stopped. Examples include “band cylinders” and vane type rotary actuators.

2. HOW MUCH LOAD IS APPROPRIATE? An overloaded actuator will be more difficult to control or stop and will also be subject to accelerated wear or failure. Manufacturers use different ways to answer this question, but one method used to quantify load is with a “load ratio”.* Load ratio for purposes of this article is: LR = (actual force/theoretical force) X 100% The actual force is the weight of the load, friction, and any other external force the actuator has to overcome. The theoretical force is the force produced by the actuator as pressure pushes against the cross sectional area of the piston and is commonly represented by the formula: F = P X A where F = force, P = pressure, and A = cross sectional area of the cylinder For linear actuators use a load ratio of 50% or less. Lower load ratios generally improve stopping performance. For example, a cylinder exerting 500 lb. of force would use a load of 250 lb. for a 50% load ratio. A 150 lb. load on the same cylinder would represent a 30% load ratio. 3. WHAT TYPE OF STOPPING PERFORMANCE CAN I EXPECT? Realistic expectations of what can be accomplished with the methods described take into account the following facts: • The compressibility of air prevents stopping an actuator with precision. Expect the cylinder to overrun a stop point and do not expect to be able to repeat a stopping at a specific point each time. • All elastomer seals used in pneumatic components have some level of leakage that will increase with wear. Expect the actuator to “drift” away from the point it stops over time unless a mechanical lock is also used to hold it in place. Do not expect a pneumatic actuator to hold position for extended periods of time by only using the method of trapping pressure with elastomer seals. • Not every factor affecting performance can be anticipated. Sizing of the actuator and components in the pneumatic circuit is theoretical. Actual performance requires validation through testing of the circuit under actual working conditions. Expect the results to vary. • Lower actuator speeds and load ratios will improve stopping performance.

METHODS USE OF A CLOSED CENTER DIRECTIONAL CONTROL VALVE Directional control valves send pressure to the port on one side of a double acting cylinder while allowing the opposite side to exhaust to atmosphere. They will have a minimum of two positions for the internal valve spool that will shift from one position to the other to either extend or retract a pneumatic actuator. A 5 port, 2 position valve is abbreviated as a “5/2” valve. A number of directional control valves will have three positions with the center position providing a specialized function. Springs on each side of the valve spool force it into the center position when no energy is being applied to shift the valve spool. A “closed center” valve blocks pressure at all ports in the center position and will trap it between the valve and actuator. This stops the actuator’s movement. “Rubber seal” valves that have a lower leakage rate are used. Avoid any valve described as “metal seal”. When a closed center valve is used, a method of safely relieving pressure from between the cylinder and directional control valve is prudent. A method of residual pressure release, such as use of a double check valve, needle valve, and 2 port, 2 position valve (abbr. “2/2”) is used in Fig 1. PILOT OPERATED CHECK VALVES A check valve only allows flow in one direction. A pilot operated check valve (abbr. “P.O. check”) stops the flow of air in one direction, but if a pilot signal is present, the valve will allow flow in both directions. A P.O. check is sometimes combined with a speed control and designed to connect directly to an actuator port or may be offered as a pair in a stand-alone assembly. When two P.O. checks are connected directly to an actuator’s ports and use a circuit that exhausts both pilot signals, they will stop an actuator in *Depending upon the manufacturer and type of actuator this relationship may be expressed as a “load factor” and use different values. WWW.IFPS.ORG • WWW.FLUIDPOWERJOURNAL.COM

either direction. For this purpose the lines providing the pilot signals to the P.O. check valves are integrated into a circuit using an “open center” (also called “exhaust center”) valve. An open center valve allows both cylinder ports to exhaust to atmosphere when no energy is being applied to shift the valve spool (Fig 2). A single P.O. check can be used for “drop prevention” when an actuator is oriented vertically. If air pressure is lost the load will be stopped when the signal to the P.O. check is exhausted (Fig3).

HARD STOPS The most accurate way to stop a pneumatic actuator in precisely the same location each time is with a hard stop. This can take a number of mechanical forms, including stops that can be moved into and out of position as needed. A critical factor in using hard stops is determining the amount of kinetic energy generated by the actuator’s terminal velocity and mass being moved and the ability of all components to safely absorb this energy. Use of slower speeds or deceleration technology such as a shock absorber may be required to prevent machine damage or a hazardous situation.

Force balance by lowering pressure with a check type regulator to balance the equation F=PXA. Used when the load is constant. F = Force P = Pressure A = Area

STOP VALVES A 2/2 valve that allows air flow in both directions is also called a “bi-directional” valve. By using air pilot signals to operate a pair of 2/2 valves connected to the actuator ports the actuator can be stopped when the pilot air is exhausted. This is similar to the type of logic illustrated in Fig. 2, but with the advantage of being able to use other types of directional control valve function than “open center”. FORCE BALANCE A “pressure center” 5/3 valve is used for a force balance circuit. This type of valve sends pressure to the A and B output ports simultaneously. The flow path in a pressure center valve forms a circuit loop from one side of the piston through the valve and back to the other side of the piston. For this reason an external force can move the piston rod unless an equal force is created on the opposite side of the piston as a counter balance. A “check type regulator” is used between a 5/3 pressure center valve and the side of the actuator piston that is exerting too much force for


counter balance. A check type regulator allows air to flow back through and around the regulator when pressure to the regulator is exhausted. As pressure is reduced, the force is reduced. When the force on each side of the actuator piston is equalized, the actuator will stop. This type of circuit logic is often used with locking actuators which require the actuator to be fully stopped before a brake is applied to prevent scoring of the piston rod and accelerated wear. A force balance can also be used with standard actuators; however, any change in the load also requires a compensating change in pressure to hold the actuator’s position. A force balance circuit also ensures that “back pressure” is present when the directional control valve is shifted to continue the extension or retraction of the cylinder. “Back pressure” is the pressure in an exhaust flow path that ensures a smooth and controlled restart of cylinder movement. If pressure is introduced to one side of the piston while no “back pressure” is on the other side of the piston the cylinder rod and load may “shoot out” with little or no control resulting in a high speed impact at end of stroke. Damage or injury can result from high speed cylinder impacts. In a “locking cylinder” circuit a 5/3 pressure center valve and check type regulator are used to achieve a force balance while a separate valve is used to operate the lock mechanism. These valves are operated sequentially so the lock mechanism is not being applied during piston movement.


PERFORMANCE For better stopping accuracy reduce the volume in the pneumatic circuit by locating the directional control valve as close to the actuator as possible. The use of precision regulators may help with repeatability if trying to stop the actuator in the same location each time. Consider leakage in the circuit as inevitable and do not rely upon elastomer seals alone to hold an actuator’s position for prolonged periods of time. Ensure the cylinder is correctly sized for the load and there is sufficient flow capacity for the directional control valves, tubing, and other components. Contact the manufacturer of the components or a certified fluid power pneumatic specialist if you do not have sizing information When a higher level of stopping accuracy is required, but use of a hard stop is functionally prohibited, consider an alternate technology such as air/hydro systems, hydraulic circuits, or electric actuators SAFETY Never employ a cylinder stopping method without redundancy, (in particular a mechanical lock) when a hazardous situation may result from a component failure in the circuit. It’s no different than crawling under your car. You don’t depend upon the elastomer seal alone in the hydraulic bottle jack (cylinder) but place a jack stand (mechanical lock) to prevent a crushing hazard. Pressure trapped within the pneumatic circuit is considered a potential safety hazard. The circuit design must account for the controlled release of trapped energy to avoid unintended consequences. The startup of an actuator after stoppage should account for the safe introduction of pneumatic energy back into the machine to prevent any unplanned motion, shoot out of piston rods, or sequence mistiming that could result in machine damage or a hazard. Always perform a safety analysis. Use a recognized safe machine design methodology such as ISO standard 13849-1. If unfamiliar with these practices, seek assistance from qualified professionals.

The Demo Expo’s education program features extensive learning opportunities with leading industry experts on the latest safety, regulatory, operational and technological issues affecting the utility and construction industry.


Association of Equipment Manufacturers (AEM)


The field demonstration concept was developed in 1964 to help solve an equipment evaluation and communications problem. Illinois Bell invited 12 trencher manufacturers to demonstrate equipment in the same field, on the same day in the summer of 1966. The show was recreated on a more formal basis and continued to grow in 1969 and 1972. Manufacturers of many kinds of equipment from across the country were invited to turn the farmland near Elburn, Illinois, into a productive 3-day utility equipment show. The event moved to DuPage County Fairgrounds for 1975 and 1977, and eventually grew to such a level that Illinois Bell could no longer manage it. The show was turned over to a professional management firm in 1978 and moved to Kansas City for the 1979 show, and Louisville, Kentucky, starting in 1987. AEM provided industry direction, and in the late 1980s became the show’s owner and producer.
