25 Years of Fluid Power Journal By Paul and Lisa Prass

HERE WE ARE with 25 years behind us since our journey began creating and producing the best industry trade journal. As I write this for our 240th issue, I reflect on our teams’ journey. It has indeed been quite an adventure. In the early beginnings circa 1993, my then-fiancée Lisa Wertman and I spent a lot of time (months) refining the concept of developing an incredible publication for the Fluid Power Society, one that would strive to bring as much relevant news as possible to our industry’s readers. The publication was the brainchild of the Fluid Power Society, and at that time I was serving on the Board of Directors and Jim Morgan was the Executive Director. There were key members of the Executive Committee, notably George Nordenholt and Fred Brown, that developed a vision to create a new publication. Lisa and I had designed and created several membership directories for the Fluid Power Society, but weren’t quite ready when the Society asked us to start a magazine. I remember the day quite well. It was at the 1993 FPS Spring Meeting when the team delivered the charge to us. A multitude of emotions shot through us on that magical day in Orlando – excitement, elation, purpose, fear, and new beginnings. At that time, we had no clue about how to produce such a large publication and how it would be published several times each year. I remember the look of fear on Lisa’s face when I told her the first issue would need to be 56 pages (it actually turned out to be even larger at 72 pages). She and I had marketing experience and a love for printed materials. Myself from learning about printing at Warren Central Career Center in Indianapolis, and then in the marketing department at The Rexroth Corporation where I worked with outstanding men like Alfred Krug and Tom Frankenfield in developing data sheets, brochures, catalogs, trade show graphics, and more for the company. Lisa hailed from Rodale Press Inc., which at the time was the publisher of many magazines including Men’s Health and Prevention, where she worked before being hired at Rexroth to design their publications and advertisements. I remember the months leading up to our inaugural issue in January of 1994. There was a lot of work to be done, and there were countless people and fluid power companies that helped turn our vision into a reality. There are way too many people to name, but a sincere thank you to all on behalf of the IFPS! Of course, with any worthwhile endeavor, there were several challenges along the way. Some that were almost insurmountable and terrifying, although many people helped us through those times, two key people were Dave Prevallet and John Groot. As I view our nation today, it makes me even more thankful and proud to have worked with the men mentioned above. They have a tremendous amount of character and were always committed to making the publication work and wanted the best for everyone in our industry. Our team is honored to serve you, our readers, and we are ecstatic to be able to publish the Fluid Power Journal monthly this year! The magazine has had wonderful success for 25 years, and the next goal is to continue to produce the best industry trade journal month after month for the next 25 years and beyond. Thank you to the Fluid Power Journal’s readers, our advertisers, our supporters and The International Fluid Power Society!  4

Hydraulic Flanges Task Force Brings Change to ISO 6162-1 and 6162-2 By Robert Mackey, Manager, SAE J518 Champion, Lead Expert ISO TC131 SC4 WG2, MAIN Manufacturing Products, Inc.

ISO 6162-1/SAE J518-1 (Code 61) and ISO 6162-2/SAE J518-2 (Code 62) hydraulic flanges have been around for more than 60 years and are in common use around the world. After years of little change, new life has come to these standards. In the last few years, the standard was split into two parts: 1) metric screws were added, and 2) the 6,000 psi series has been extended to include the -40 (2-½ inches) and -48 (3 inches) sizes, as well as numerous other internal changes. In addition—a part 3, if you will—a very low-pressure flange has been added for a two-bolt. This work was done in the SAE Fluid Conductor and Connector Technical Committee, FCCTC, through the C2 (Hydraulic Hose and Fittings Committee), then taken up to the ISO working group once passed by SAE. These groups are working on two additional parts to standardize various in-line, elbow, and tee connector blocks. They are also discussing redoing the dimensioning of the standards to follow GD&T conventions. The C2 Committee is also looking at creating a new part (part 6) to help standardize higher-pressure flange fittings.

WWW.IFPS.ORG • WWW.FLUIDPOWERJOURNAL.COM

The task force is conducting a short survey as an aid in creating a new part to help standardize higher-pressure flange fittings.

  

Do you use fittings for the sizes and pressures above? Do you manufacture fittings for the sizes and pressures above? Do you know of any manufacturers of these fittings?

If you answered YES to any of the above: Who was the manufacturer? What sizes and pressures are manufactured or of interest to you? Is there any literature that could be shared with the task force? Is the fitting covered by a patent? What is the general application? Please send responses to the task force leader, Robert Mackey at info@mainmfg.com or call 800-521-7918. Any information and direction would be appreciated.

The hydraulics industry, especially the oil and gas market and the mobile market, have been moving to higher pressures. Several manufacturers are manufacturing hydraulic hoses, pipes and tube fittings up to and beyond 50 mm (2 inches) with pressures exceeding 56 MPa (≈8,000 psi). To further this work, we are conducting a survey to find flange style fittings that are currently being manufactured for use at pressures in the 56 MPa range and sizes from -24 (1-½ inches) to -48 (3 inches). If you would be interested in working on this task force, we are meeting in Louisville, Kentucky in September 2019. It will be sponsored by the SAE FCCTC and will include all FCCTC committee meetings, in conjunction with the USTAG to ISO/TC 131/SC 4, and the ARPM Hose Technical Committee meetings. Visitors are welcomed at all meetings and WebEx may be available if discussed beforehand. 

HOSE REPLACEMENT

by measuring existing assembly to make a duplicate

HOW TO MEASURE HOSE ASSEMBLIES AND HOW TO MEASURE CUT-OFF LENGTH. Once the proper hose and fittings have been selected, the assembly can now proceed. Components, equipment and procedures will vary for all types. However, measuring, cutting and fitting orientation procedures are the same for the styles of fittings: • Permanent crimped • Permanent swage • Field attachable

AUGUST 2019

MEASURING HOSE TO DETERMINE HOSE CUT-OFF LENGTH: With some assemblies, the length must be within tight tolerances for proper installation. This is especially true for short, high pressure hose assemblies. If a hose assembly is shorter than the manufacturer’s recommended length, the likely result will be hose separation failure. NOTE: Before cutting the hose, make sure you understand the difference between cut hose length and overall assembly length (OAL). The hose cut length for a hose assembly is calculated by subtracting the cut-off factor (distance from the bottom of the ferrule or collar to the end of the fitting, dimension “C” in Figure 1). Typical length tolerance: Up to and including 300mm, ± 3mm (12”, ± 0.13in), up to 450mm, ± 5mm (18”, ± 0.19in), up to 900mm, ± 7mm (36”, ± 0.25in), over 900mm (36”) ± 1% of length.

Figure 1

Unless otherwise specified, assembly length shall be the overall length measured from the extreme end of one fitting to the extreme end of the other, except for o‑ring face seal type fittings which shall be measured from the sealing face. Where elbow fittings are used, measurement shall be to the centerline of the sealing surface of the elbow end. (The sealing surface of female flared elbow fittings shall be the centerline of the outer end of the cone seat.) See Figure 2 examples of OAL measurement on the next page.

Looking BACK/FORWARD

YEARS By Dan Helgerson, CFPAI/AJPP, CFPS, CFPECS, CFPSD, CFPMT, CFPCC

AUGUST 2019

WWW.FLUIDPOWERJOURNAL.COM â&#x20AC;¢ WWW.IFPS.ORG

A careful look at the last 25 years in the fluid power industry reveals both exciting and distressing news. We tend to look at the ground immediately in front of us and seldom lift our eyes to the horizon to see what may lie ahead. We often take action based on the immediate and the urgent, rather than by future potential and the important. We are restrained from taking risks because of the perceived consequences of failure. The “bottom line” has become the bottom line without a view to what will best meet the needs of those who rely on our products and designs.

LOOKING FORWARD In 2014, Peter Achten of INNAS BV, made a presentation about innovation to a group of leaders involved in the fluid power industry. He revealed that, in the area of commercially available hydraulic pumps and motors, there has been only incremental improvements during the past 25 years. This is not to say there are no improvements, but that the improvements have been minor alterations in existing technology. It seems that once a new technology has been embraced, it becomes the standard, and few can imagine any serious deviation from the concepts. Companies ride the success of the new technology with minor iterations to meet market demands. He pointed out that innovation comes in two forms: incremental and disruptive. A disruptive innovation is a product or concept that completely changes the landscape, disrupting markets and sometimes putting companies out of business that were not prepared for or receptive to the change. The disruptive innovation is usually followed by incremental innovations as the

realized or materialized.” This is what produces wonderful, disruptive innovations. For example, the iPhone was introduced into the market and had a disruptive impact all over the world. It was not asked for by the market, but it was imagined, developed, and introduced. The smartphone quickly replaced the mobile phone and had a major impact on the camera industry as well. Since then, there have been incremental innovations that will likely continue as the technology matures. The fact that there have been no “disruptive” innovations in fluid power for over 25 years should not be distressing. It should be exciting. It means that we will have an opportunity to embrace the new TWO KINDS OF INNOVATIONS technology when it comes, and it is coming. There are several, totally new concepts on the horizon. With hydraulics, there is the floating cup technology for pumps, motors, and transformers; Digital Displacement® pumps and motors; and the Variable Displacement Transformer. In pneumatics, there is load sensing, digitized control, and the pneumatic VDT. And there technology matures.

LOOKING BACK It is not the nature of most companies to crave disruptive innovations. We are more likely to try to maximize profits with what is common and comfortable than to take risks on a radical new idea or a new way of thinking. So it was in 1994. Large fluid power distribution companies were buying up relatively small, family-owned businesses and attempting to merge them together into cohesive organizations. These large companies were competing against each

other for a share of the fluid power distribution business, not to provide a better product, nor to increase efficiency, but to improve the bottom line. To be competitive, it would be necessary to reduce operating costs. The small companies that had been bought had serviced loyal customers by building hydraulic power units, designing and/or putting together pneumatic systems, and providing technical help. The new companies thought

it would be more efficient to centralize engineering and manufacturing. Distribution and manufacturing centers were set up, strategically located to provide quick delivery of components, using call centers staffed with people who would answer phones and write orders, and who needed very little knowledge of fluid power. Fluid Power Certification was neither a requirement for employment, nor necessary for advancement. The number of people who did application engineering was reduced with the idea that much of the engineering could be pushed back onto the component manufacturer. However, the same culture was permeating the industry at the component manufacturing level. The large manufacturers were attempting to grow by acquisition, buying up smaller, independent companies, and merging product lines.

...DISTRIBUTORS AND MANUFACTURERS ARE BEGINNING TO RECOGNIZE THE NEED TO HAVE CERTIFIED FLUID POWER PROFESSIONALS RESPONDING TO CUSTOMER NEEDS. THERE HAS BEEN A STEADY INCREASE IN THE NUMBER OF CERTIFICATIONS ISSUED BY THE INTERNATIONAL FLUID POWER SOCIETY.”

Some of the engineers from the smaller companies were not included in the mergers with the thinking that their skills would be redundant to the existing engineering staff. This caused a depletion of some of the expertise required to support the new product mix. At the same time, manufactures focused on larger OEMs because this would have the greatest impact on the bottom line. They geared their production to meet the demands of large quantities with a narrow product mix. Distributors found that products with high demand were having longer lead times and products with more narrow applications did not have strong support from the factory. Application engineering was being pushed down to distribution. The net result was that the end users were caught in the middle. If technical help was needed, the new distribution companies often lacked the depth of engineering skill to properly address the issue and the understaffed manufacturers were overwhelmed with requests for help from distribution. WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

This trend has continued, but distributors and manufacturers are beginning to recognize the need to have certified fluid power professionals responding to customer needs. There has been a steady increase in the number of certifications issued by the International Fluid Power Society. Ironically, the number of community colleges that are offering quality fluid power training is diminishing. This is not to say that there have been no significant innovations or changes in the industry over the last 25 years. On the contrary. One of the most remarkable changes in the industry has been the advances in electrical and electronic controls. In hydraulics, advancements in proportional valve technology has allowed these valves to replace a large portion of the market that was once dominated by servo valves. Proportional control of pneumatic components has had a great impact on the efficiency of pneumatic systems by providing infinite adjustment of pressure regulators and flow controls. Pneumatic valves have become much smaller without diminishing flow rates and so the energy to power the solenoids that drive pneumatic valves have steadily been decreased. What once required 4 Watts of power

There has also been a change in the demographic of those entering the field of fluid power. Programs like Lead the Way and FIRST Robotics have encouraged high-school students to enter fields of engineering with fluid power being a major draw. Young women who are interested in science and technology are being encouraged to pursue careers in these areas. As a result, more and more women are entering the field and taking leadership positions.

While the industry has a long way to go in the area of efficiency, the awareness of the need has grown steadily, and some remarkable products are coming into the market. The load sensing, variable displacement pump was an improvement to the pressure compensated pump. Then came torque limiting and power limiting pumps that allowed both mobile and industrial equipment to use smaller prime movers, which reduced installed cost as well as saving energy. The new

is now using as little as 0.1 Watts. Wireless controls of mobile hydraulics and pneumatic manifold systems have replaced delicate wiring. Manifolds have helped reduce the size of hydraulic control systems as well as reduced the number of potential leakage points. Pneumatic manifolds serve as communication hubs on an industrial fieldbus network, managing inputs and outputs for many devices in addition to the directional control valves. Venturi type vacuum generators have been redesigned to provide high vacuum levels with relatively low air pressure, typically under 3.5 bar (50 psi). The Internet of Things (Industry 4.0) is becoming very important, allowing predictive maintenance based on real time data. The technology improvements in variable frequency drives and vector drives have also helped to make more efficient systems. Relatively inexpensive, fixed displacement hydraulic pumps can be driven with vector drives, providing the exact flow requirements for the system. The same drives run air compressors, providing on-demand air.

digital pumps and motors are entering the market and allow computer controlled, nearly instant, pump and motor displacement control. A study by Oakridge Labs brought the industry to the attention of the U.S. Department of Energy (DOE) and led to the creation of the Center for Compact and Efficient Fluid Power (CCEFP) with grants from the DOE to develop more efficient components. In addition, the conferences on Energy Efficient Hydraulic and Pneumatic Components (EEHCP) looked for ways to produce more efficient systems that would incorporate the newly developed efficient components. As demand for smaller and lighter systems grew, especially in the mobile market, higher pressures are being used today than would have been considered 25 years ago. These higher pressures demanded better machining for tighter tolerances to reduce internal leakage. New hydraulic fluids, sometimes with special additives, that could maintain the appropriate boundary layers for lubrication were developed to meet the needs of the better machined components. The tighter tolerances also demanded better filtration and better means of determining fluid cleanliness. Studies were conducted to determine how clean the fluid would have

to be to prevent failure of various components. This is now known as the ISO Cleanliness code. It requires counting three reference sizes of particles: 4 µm, 6 µm, and 14 µm in a volume of fluid evaluate the cleanliness of that fluid. And lubricating pneumatic components has become a thing of the past. Another major change, and a matter of some consternation in the U.S., is the incremental move to the metric system. Quoting Richard Bullers, “We are moving into the metric system, inch by inch.” Due to more and more

Responding to this, the International Fluid Power Society is upgrading its study manuals, its certification exams, and its Math for Certification booklet to show all equations in both metric and U.S. Customary terms (see example in chart below). Yes, we have come a long way, and there are even greater advances on the horizon. Welcome to the future of Fluid Power!

COMPRESSED AIR SYSTEMS

Shop Compressors:

One or Two Units? By Ron Marshall, Marshall Compressed Air Consulting

Âť

WHEN PURCHASING SHOP compressors, do you buy one unit or two to make an energy efficient choice? The answer depends on the type of compressor chosen.

RECIPROCATING COMPRESSORS The traditional compressor type for small shops is the piston-style compressor. These units are great for automotive shops with very light loads with occasional peaks when large tools are used, but they have their drawbacks. Reciprocating compressors are noisy and usually run hot. In fact, this compressor type is typically not rated for continuous duty. This is because the cooling system is very simple, typically just a fan designed into the drive pulley, and a copper pipe with fins to cool the air. If these compressors

Figure 1: Duplex reciprocating compressors may be less efficient at full load, but are efficient at part-loads.

Stops Leaking

FlangeLock™ are heavily loaded for extended periods they will overheat, damaging the compressor internals and reducing the compressor capacity. A second compressor can be added, like the tandem unit in the accompanying photograph, but the two compressors must be carefully controlled so as not to allow one of the compressors to run continuously and burn out. This type of compressor is not very efficient at full load, but the design makes up for this failing in being very good at handling low loads. So this inexpensive-to-maintain compressor style would be a good choice for shops with low loads. One compressor or two would not make a difference in efficiency. SCREW COMPRESSORS Many shops choose screw compressors when they modernize their systems. These devices are quiet, run at any duty cycle, and can run at full load throughout the whole life of the unit if required. The cooling systems of these units are usually more complex and result in the compressors discharging compressed air at slightly above ambient temperatures, making it easier to dry the compressed air output, better eliminating moisture from the airstream. But the common fixed-speed type of screw compressor has a few disadvantages compared to reciprocating style. The maintenance costs are often much higher since the units are more complex and use specialty lubricants and filters. Also if installed with a normal-size storage receiver capacity, this compressor type can continue to run unloaded, wasting power, even when producing no compressed air. This can be a problem if one large compressor is purchased instead of two smaller ones. A typical screw compressor consumes about 35% of its full load power when unloaded, whereas a reciprocating compressor consumes no power. A larger-than-needed screw compressor installed in a shop environment can accumulate many unloaded run time hours of double the waste if the average flow is low. If this is the case, it pays to purchase two smaller compressors rather than one large one. And if a larger-than-normal storage receiver is installed with the compressor, a screw compressor can run in start/stop mode just like a reciprocating unit. Another solution might be to purchase a variable speed drive compressor which may eliminate unloaded run time altogether. 

Flow Transmitters Enable Remote Monitoring of Flow Meters – Even in Hazardous Areas By Chris Husson, Senior Design Engineer, AW-Lake Company

Early version of the flow meter

a scaling factor for the rate and total screens to show values. If mounted in a hazardous or dirty environment, the unit included a magnet that enabled users to change readouts between the rate and total displays or to reset the totalizer without removing the cover and exposing the sensitive electronics to the environment.

MANY INDUSTRIES IMPLEMENT flow meters to monitor the flow of liquids or gas during various operations to ensure accurate manufacturing processes while avoiding excessive costs. As some flow systems incorporate many flow meters, monitoring them can be labor intensive, taking hours for operators to travel to multiple locations and connect meters to get readings. Flow transmitters provide a continuous output of flow data that can be read by operators without the need for additional instrumentation. Some operate in hazardous environments, while others offer connection options to remote monitoring systems. AW-Lake Company even offers a batteryoperated version that works wirelessly. But in the early days, the only displays available for flow meters were panel mount units requiring an external AC or DC power supply. Understanding the market need for simpler meter-mount displays not requiring expensive wiring, AW-Lake introduced the RT-EX2 Battery-Powered Flow Display in the 1990s, the first battery-powered flow monitor mountable on meters and operable in remote areas where power was unavailable. Powered by a single D-cell Lithium battery with a four-year minimum battery life, the RT-EX2 offered long life and simple setup by entering

Moving from a monitor to flow transmitter

Monitor and program flow meters from a smart device

MOVING FROM A MONITOR TO FLOW TRANSMITTER Using customer feedback and advances in technology and design ideas from its engineering team, AW-Lake made significant design improvements to the original RT-EX2 and introduced a new version called the RT-10 Battery-Powered Flow Rate Transmitter in 2006. Improvements in the sensor input circuitry increased the allowable maximum signal frequency from 800 Hz to 3000 Hz, extending the range of turbine flowmeters for use with the flow rate transmitter. Where the RT-EX2 was just a monitor without any external signal connections, the RT-10 added a fiber optic output option, making it possible to send a 0-100Hz flow signal remotely. Also, a 4-20mA loop output option supported remote monitoring of the flow rate in addition to the local display. In applications where flow rates appeared erratic, an added gate time filter provided the option to smooth the flow rate display as well as the 4-20mA loop output signal. To maintain a long battery life with the improved functionality and additional options, a programmable sleep timer put the unit in a low power state when no input frequency or button activation was detected after the programmable sleep time

T H E N A N D N OW passed. To aid in preventative maintenance, the RT-10 also displayed a warning about low battery life so operators could schedule battery replacement at a convenient time rather than waiting until the battery died and the unit no longer worked. MONITOR AND PROGRAM FLOW METERS FROM A SMART DEVICE AW-Lake recently introduced its third generation of battery-powered flow monitors that mount directly on the meter with the RT-50. As many operators prefer to use smart devices in monitoring operations remotely, the

RT-50 Battery-Powered Flow Rate Transmitter offers Bluetooth capabilities to view readings and adjust the rate, total, reset, or time on a smart device. A graphical multi-line display and improved front panel user interface buttons simplify reading flow rate or total while programming units. When using Bluetooth connectivity, users can connect to the RT-50 from a smartphone or tablet to create a wireless flow monitor that works in the palm of a hand. Other enhancements include a 10-point linearizer that improves the accuracy of any flowmeter, especially for applications where meters are used outside of their published

Incorporating wireless sensing technology

specifications. Units also are programmable to store total values at a set time of day. A battery backup of totalizer values assures that data is not lost when replacing the battery. INCORPORATING WIRELESS SENSING TECHNOLOGY WITH AW-LAKE FLOW METERS Many flow systems utilize a network of flow meters that requires wiring or daisy chaining a network of instruments by cable to a large interface panel. Cabling can cause a cascade of issues costly to repair. Using radio frequencies or Bluetooth communications, it is now possible to connect multiple sensors and flow meters into a secure mesh network that can be accessed remotely by personnel. Data from flow meters is extracted by a radio- or Bluetooth-enabled node and transmitted to a central gateway, which can interface with local WiFi networks to provide real-time flow data on demand. Working with its sister company SignalFire Wireless Telemetry, AW-Lake can combine its flow transmitters with integrated wireless nodes that intuitively connect in a secure mesh for safe, real-time flow monitoring on the go. 

NOAH SANTONI OF Richardson, Texas, is the winner of the 2019 NFPA Robotics Challenge Scholarship. The scholarship program received 76 applications this year and helps build awareness of fluid power benefits and careers among high school students. This scholarship program awards $40,000 ($10,000 per year for four years) to a high school senior who participates in a FIRST® Robotics or National Robotics League Competition Team and uses fluid power in the competition robot. The money awarded may be used to study engineering at any accredited technical college or university in the United States. Noah will be using the scholarship to pursue a degree at Case Western Reserve University in Cleveland, Ohio. Noah already has a background in a number of engineering-related activities: I live in Richardson, Texas (a suburb of Dallas) and I went to Jesuit College Preparatory School. My hobbies include reading, board games, 3D printing, 3D design, and robotics. I chose to attend Case Western Reserve University because of the mid-sized student body, its plentiful research opportunities, and its incredible maker space on campus. On top of that, its focus on strong academics and excellent engineering program creates an environment I think I will thrive in. I participated in FIRST Robotics for all 4 years of high school. I was a member of Team 2848 for 3 years, playing in the finals in 2017 and winning the Dean's List award in 2018. In 2019 I helped create Team 2714, a brand new Dallas area community team. We won two industrial design awards and made it to the championship. This scholarship will allow me to go to Case Western and release a lot of the financial pressure on my parents and me. Not only will it let me focus more heavily on school work, but it will also allow me some breathing room over the next four years. This year, fluid power was the reason my robotics team was successful as our two mechanisms that scored points required fluid pressure. Additionally, fluid power was the easiest way to accomplish the FIRST Robotics Competition challenges. It ensured that my team moved on to the championship. Going forward I want to learn more about and explore hydraulic systems, as FIRST does not allow those in their competition.

Action Challenge Grant Helps Promote In-Demand Careers

THE NFPA EDUCATION and Technology Foundation awards grants of up to $500 per year to middle and high schools to help facilitate hydraulic and pneumatic instruction that introduces students to fluid power technology and career options. Schools can apply for these grants annually, and they can be used either for classroom activities or to help cover the costs associated with participating in the Fluid Power Action Challenge event. Here is what one of many grant recipients had to say about the grant’s impact:

“The teacher and students at Alcoa High School are really grateful for the funding received from the NFPA. We were able to purchase functional mini hydraulic arm construction kits for our introductory advanced manufacturing course. This course is helping to promote in-demand careers in advanced manufacturing in our area, and the funding you provided allowed us to reinforce course standards relating to fluid power in a fun, hands-on format! We had around 65 students participate in our advanced

manufacturing courses this school year… The primary student outcome was that students were able to learn concepts while being able to build a fully functional hydraulic arm. We would definitely do this activity again.”

To learn more about how your company can help support these grants or help facilitate a Fluid Power Action Challenge event in your area, please contact Stephanie Scaccianoce at sscaccianoce@nfpa.com.

VACUUM PICK & PLACE

DIRECT FOOD & DRUG CONTACT By Dane Spivak, Davasol Inc.

The food and medical industries hold themselves to higher standards than most. Over the years, many of these manufacturing standards have been adopted at the corporate, national, and global levels with the purpose of providing the consumer consistent and safe-to-use products. Vacuum pick and place involving direct food or drug contact is a familiar manufacturing process applied around the world. The following article shares techniques to design successful vacuum pick and place systems while adhering to industry requirements.

Like most applications, the first instinct is to select a vacuum cup that will create a good seal and allow for a confident grip on the part. However, given the cup will be in direct contact with a product to be ingested, we must first find the appropriate credentials to allow for safe contact. The Food and Drug Administration (FDA) is an agency based in the United States that is responsible for public health by assuring foods are safe, wholesome, sanitary and properly labeled.1 The FDA compliances have grown globally due to the large amounts of imports and exports throughout the world, and therefore many companies practice

their policies. Other agencies and policies exist though the FDA is most popular and relevant particularly in North America. The standard for suction cup material is FDA 21 CFR 177.2600. The primary need for FDA compliant vacuum cup material is, first, to ensure it is safe, and second, to allow for only a minimal amount of material to be leeched off the cup and onto the product. The maximum allowable amount of leeched material for approval is iron dust

Figure 1 – Metal filings inside vacuum cup

extremely low, which would be deemed virtually non-existent. The go-to material for food grade cups is silicone, which is used in most applications. But be careful, just because a cup is made of silicone does not necessarily mean it is FDA compliant. Manufacturers of vacuum cups often list FDA cup material compliant models. Users 40

AUGUST 2019

may request the FDA material compliance certificate from the manufacturer for verification. Silicone cups are often white or red in color though many other colors exist. White tends to be the color of choice for direct food contact though the cup color does not determine its suitability for FDA contrary to what is believed. Depending on the product, certain colors are chosen to be able to distinguish between the cup and the food. For example, a green cup would not be ideal to pick cucumbers. A red color would be better suited so the cup can be seen and identified should a piece fall off the machinery. On the subject of cups or pieces of a cup falling from the machinery, it is important to identify the situation quickly and locate the unwanted cup pieces. Product recalls happen on a regular basis, and in food and medical, it can very well be the cause of a vacuum cup getting lost in product packaging. There have been instances where millions of dollars’ worth of food products are recalled. A common solution to avoid this problem is using metal detectable vacuum cups. These are vacuum cups where iron dust is incorporated inside the compound as shown in Figure 1.

Figure 4

At some point after the pick and place process is complete, all products are run through a metal detection device. Should a cup piece, or any metal component for that matter, trigger the detector, the product or product package can be identified and dealt with accordingly. Conveniently enough, silicone cup materials can be metal impregnated and meet the FDA compliance as well. The result is a metal detectable FDA compliant silicone cup, which is a popular choice among users and machine builders when dealing with vacuum pick and place applications for direct food contact. Depending on the organization, the tool and other surrounding components may also require these characteristics even though they are not in direct contact with the food. For that reason, these parts are often made of specific materials to meet manufacturer’s needs as well. Stainless steel being the leading and obvious choice of material. Figure 2 shows a vacuum tool in stainless steel that uses food grade metal detectable vacuum cups. Stainless steel also offers

Rotary Vane Pump

washdown resistance, which is often needed in unpackaged areas of the food manufacturing process. Now that we have checked off the list of standards, we can move on to designing a system to pick and place the food or medical goods. The nature of these product surfaces tends to be curved, uneven, or rough, so selecting an appropriate vacuum cup to create a good seal is essential. For these reasons, bellows vacuum cups are more common than flat cups. Bellows refers to the fold(s) in the cup that allow for height and angular compensation, as well as a protruding sealing lip. Figure 3 shows a single bellow vacuum cup sealing against a wafer bar. The bellow allows the cup lip to deform to the wafer surface, which offers a good seal. Figure 3 demonstrates the use of a typical 10mm single bellow vacuum cup, though many different shapes and sizes of cups exist.

Figure 6 – Relief valve installed on blower and relief valve on its own with adjustment screw WWW.IFPS.ORG • WWW.FLUIDPOWERJOURNAL.COM

Venturi Generator

Some with many more bellows that offer additional height and angular compensations; others with varying lip and web thicknesses providing different sealing capabilities. Choosing the best vacuum cup by eye can be difficult. To ensure the proper selection is made, testing is recommended for confirmation of a secure product grip. Vacuum pumps or generator units work in conjunction with the vacuum cups to create a seal on the product. Selecting the pump type and size determines how the cups interact with the food and overall system performance. Typical vacuum generation units in the food and medical industries are venturi generators, vane pumps, and regenerative blowers. Examples are shown in Figure 4. Considering many food products are lightweight with irregular surfaces, vacuum flow is the key performance feature. Vacuum flow is the rate at which air is removed

Figure 5 – Cup gripping swiss roll

Regenerative Blower

from the vacuum system. Higher flows can help cups engage in a better seal and also compensates for other leakage present in the system, such as porosity or cups that are not sealed altogether. Vacuum levels are what determines the lifting force a cup can provide, but without the right amount of flow to create a good seal, the vacuum level could remain at zero. When dealing with lightweight products, higher vacuum levels of 24”Hg (80% vacuum) are not needed and sometimes undesirable. The higher the vacuum level, the higher the exerted pressure the product experiences. This can be detrimental to the food surface by leaving a mark or causing damage. Figure 5 shows a multiple bellows vacuum cup lifting a swiss roll. The lightweight swiss roll has a delicate surface, and therefore a low vacuum level is used for this application. Regenerative blowers, sometimes referred to as side channel blowers, are a popular choice for vacuum pick and place in direct food contact applications. Blowers provide relatively high flows while using little energy and generate low-to-middle ranged vacuum levels, precisely the performance needed for the reasons described in the previous paragraph. Blowers are usually coupled with a vacuum relief valve whose primary job is AUGUST 2019

to relieve pressure in the blower should it climb too high (Figure 6). This is accomplished by allowing atmospheric air to bleed through the relief valve and back into the pump. Most relief valves are adjustable, which can offer the user flexibility as the relief valve can be metered to change the maximum allowable vacuum level. To add to its versatility, some blowers can also use variable frequency drives to increase or decrease the flow and vacuum levels. Venturis and vane pumps are also used in food pick and place applications. When comparing similar power rated units, they offer less flow, but higher vacuum levels than blowers. These units are better suited for applications where the product is heavier, and the surface is easy to seal against. Venturis use compressed air to create a vacuum and are not good at generating flow at higher vacuum levels. They are

also usually designed to reach vacuum levels of 24”Hg (80% vacuum) or higher. Vane pumps are electrically powered liked blowers, but do not operate well under approximately 21”Hg (70% vacuum). Lower vacuum levels can cause unwanted vibrations and oil leaks. Vane pumps can be quite large and provide high flows, but not nearly as efficiently as blowers. Comparable performance graphs are shown in Figure 7. The food and medical sectors certainly have high standards and expectation of quality products. All for justifiable reasons. This article covered methods in vacuum pick and place to meet the needs of the industries while providing a technically sound solution. Standards are constantly changing by company and geographical location. Professional help should be sought to ensure the appropriate solution is implemented. 

New Problem

Cable Puller Motor Speed Problem

By Robert Sheaf, CFPAI/AJPP, CFPE, CFPS, CFPECS, CFPMT, CFPMIP, CFPMMH, CFPMIH, CFPMM, CFC Industrial Training

A CONTRACTOR FOR a power and light company was hired to pull new wires and cable needed for a new plat of homes being built. The hydraulic puller unit incorporated a small gas engine and pump assembly to rotate a hydraulic motor with a rope attached to the cable they were pulling. The unit would pull enough cable to reach the next power pole plus extra to reach the ground. They would stop the pulling, disconnect the rope from the cable, thread the cable over the next pole, and down to the puller that was moved to the next position. The pump would recharge the accumulators (only one shown on the circuit), while the unit was moved to the next position. The accumulator and pump would wind the rope up at a constant speed based on the accumulator’s flow control setting. On one of the pulling cycles, the motor speed increased to a high rate decelerating down to a slow rate. The team checked the accumulator pre-charge and re-adjusted the flow control several times and the motor would still start off at a high speed and ramp down to a slow speed. Any idea what is causing the problem?

olution to the previous problem: Piston pump keeps failing on a large shear

When a shoe on a piston is pulled or worn off, it normally is an indication that there is a high intake vacuum or high case drain pressure. Since the pump grenaded again and the intake vacuum was fine, it had to be due to high-case pressure. The team was told to remove and inspect the case drain line where they found pieces of the old failed pump piston shoes partially blocking an elbow fitting, causing high-case pressure that pulls the shoes off the main pistons.

Developing a Liquid Piston Gas Compressor/Expander

for CAES and CO2 Sequestration

Presented by: Perry Li, Professor and Deputy Director of CCEFP, University of Minnesota

PURPOSE The goal of Perry Li’s project is to develop a prototype of a reciprocating high pressure (~200bar), high efficiency, liquid piston gas compressor within 18 months of the September 2018 start date. The prototype could be used for projects related to industrial gas preparation, grid scale Compressed Air Energy Storage (CAES), and carbon dioxide for sequestration or reuse. Due to global climate change, there’s been a significant shift toward renewable energy. However, not all renewable energy is consistent, creating a dilemma for energy suppliers. To address the abundant, but intermittent challenges of renewable sources, companies often rely on “non-renewable” plants that supplement the energy supply from renewable sources during peak demand. The team is aiming to develop a grid scale energy storage device to replace peaker plants that will increase revenue and stabilize electrical grid frequency.

PROGRESS The process of creating an air compression/ expansion component is met with the challenge of how to address energy loss. The team tackled the isothermal emissions as an attempt to reduce energy loss and were met with positive results. To increase this power expansion significantly the team learned that they needed to increase the heat transfer, using a modified version of the first law of thermodynamics.

Li and his team discovered that with the use of liquid piston compressor/expander with porous media, you can increase the heat transfer rate. This liquid piston compressor/expander allows the device to make heat transfer more efficient and piston trajectory more controllable. When comparing the effect of porous media, the team reviewed the system with various sizes of the liquid piston compressor/expander chamber. During the tests, adjustments to the distribution of heat transfer in porous media, the shape of the chamber, and the flow trajectories dramatically affected the performance and efficiency, supporting the team’s original strategy. In a realistic heat transfer model, the optimal flow can be adjusted over time, leaving an improvement in power density three times more efficient than before. Several tests demonstrated a consistent increase of 92% efficiency across multiple cases adjusting porosity, flow rate, and chamber design.

NEXT STEPS The plan moving forward is to make the liquid piston gas compressor/expander more operable by developing a prototype that can be reusable. The team’s target is a 5kW prototype design with a compression time of 1-2 seconds. To do this, Li and his team will focus on valve design, liquid piston sensing and control, and dead-volume management.  WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

MEETING THE CHALLENGES OF

exceeding expectations, and creating value for medical providers, practitioners, and patients. There are many challenges that manufacturers face when designing a custom solution and it’s important that both the customer and the manufacturer have an open line of communication, with complete transparency, throughout the design and development process. Communication, or lack thereof, can dramatically drive up material, labor, and engineering costs, extend a projects timeline or release schedule, and most notably, can cause an increased probability of failure. According to the U.S. Food & Drug Administration, “each year, the FDA receives several hundred thousand medical device reports of suspected device-associated deaths, serious injuries, and malfunctions.” Malfunctions can come from a number of different variables, and don’t necessarily derive from a fluid power component or an isolation valve. However, the FDA and other governing bodies that control the medical market, focus on and pay close attention to malfunctions, failures, and other types of issues. After reading this quote from FDA.gov, Phil Muntean, chief engineer of Spartan Scientific, explained that “Any device or any media within a valve that can potentially come in contact with the human body necessitates additional approvals or adheres to additional standards. When discussing a new project where we’ll be engineering a custom solution, we keep in close contact with our customers and end users in order to execute any additional testing that may be involved either by our manufacturing facility or by an outside source.” Other ways to ensure an engineered solution has followed the correct testing procedures using the most up-todate testing parameters is to gather information through market research, competitive research, or related predecessor solutions. According to the Department of Commerce, “the United States represented about 40% of the global medical device market in 2017 and the medical industry is responsible for approximately 2 million jobs located in the U.S.” The future for manufacturers looks light a bright one, but creating value is mandatory for companies in this competitive market. To survive, manufacturers and companies alike will need to overcome future challenges pertaining to the issues like the emergence of IoT Technology, more innovative product design and product quality, regulatory compliance, and approvals. 

MEDICAL

Processing Manufacturers By Pat Byce, Marketing Coordinator, Spartan Scientific

Over the years, the medical and analytical markets have regularly undergone positive developments and technological advancements. These devices and processes are often made up of numerous components from various manufacturers throughout the world and have a direct relationship with the advancement of the medical and analytical industries. Fluid power and the ability to control a media, such as a gas or liquid, has remained a fundamental principle of medical and analytical technology. More specifically, isolation valves also known as media separated valves are frequently used in today’s medical industry and are found in many different processes and devices, mostly because of their simple functionality, cost effectiveness, reliability, and repeatability. To understand the vital role that isolation valves play within medical markets, it’s important to understand the idea behind isolation valves and to recognize that “one size fits all” does not apply. An isolation valve is used to control the flow of a media, while ensuring WWW.IFPS.ORG • WWW.FLUIDPOWERJOURNAL.COM

the media remains isolated or separated from any contaminants or hazardous materials that could potentially cause a device failure, or even worse, put something or someone in danger. Examples of common medical medias include blood, plasma, dialysate fluid, steam, disinfectant fluid, CO2, oxygen, and water. Different media types can, and usually do, belong to different applications, which in turn requires additional variables to be considered such as valve functionality, physical size requirements, actuation or response times, seal or diaphragm materials, dead volume, and/or life span.
