Not All Training Is Created Equal By Denis Poirier Jr., CFPAI/AJPP, CFPHS, CFPCC, CFPIHM, Eaton Corporation Hydraulics Group
»
CERTIFICATION CAN BE defined as “a benchmark that validates a minimum level of understanding through academic and performance-based testing.” Certification is at the foundation of the International Fluid Power Society. The society offers multiple certifications designed to satisfy an array of industries. If you work in hydraulics, pneumatics or electronic controls, IFPS has a specialist certification for you. But the number one conversation I have is not about attaining certification; rather it’s about the training required to attain certification. Some people believe that attending a review session will pull them through the certification process. But a review is not an all-inclusive training session. The purpose of a review is to hone your test-taking skills, refine your ability to efficiently navigate supplemental testing resources and enrich your understanding of complex material. To achieve those goals, an individual must understand the content before attending the review. As a degreed professional in the field of adult education, I can tell you that training is the most complicated part of the certification process. In many instances, organizations embrace training at the core of their business. Leadership and management alike rely on training to satisfy company requirements, human resource standards and system mandates. We use training to satisfy sales force requirements, personal development and equipment certifications. Training is the power that cures all deficiencies. But not all training is equal; neither are all training outcomes equal. If we take a high-level view of training, we can categorize it into three basic groups: broadcast, facilitation and technical. In the broadcast format, information is delivered to promote a level of awareness. This works best with large groups in which minimal or no interaction with the audience is required. Information is transmitted to the student, but feedback from the student or the instructor is not transmitted. In the facilitation format, a facilitator guides the session. Role playing and scenario-based classes might be used in conjunction with coaching. Two-way communication is encouraged, group participation is often a requirement, and feedback is provided throughout the course. In the technical format, an instructor leads the class through defined course objectives. Specific outcomes are used for academic assessment. Methods include solving multistep mathematic equations, reading schematics and interpreting engineering drawings. Performance-related objectives may include detailed disassembly and reassembly of components and exercises to evaluate proficiency in critical skills. Each of these three groups is considered training. If you are a decision maker who influences those seeking certification in the fluid power industry, it is important to select the proper training delivery method for the talent you wish to develop. This seems like common sense, but many times individuals are sent by management to a review session without the proper level of training. Managers are then disturbed when their employees don’t pass the test for certification. (Continued on page 5) 4

(Continued from page 4) If you embrace online training, you should understand that developing electronic content is expensive. One hour of basic e-learning content that includes graphics, limited interactivity and simple testing has a median cost of $9,000 to $11,500 per hour. Content that includes dynamic media, custom graphic interfaces, an increased level of interactivity and complex testing has a median cost of $26,000 to $38,000 per hour. More advanced content carries a median price tag of approximately $100,000 per hour. When you consider these numbers, electronic training methods become a quantity of scale. If a company has 75,000 employees, it is easier to accept a median content development price of $30,000 dollars per hour. But if your company has 100 people, the conversation changes dramatically. Electronic delivery of training content can be as effective as instructor-led training if both methods use the same design principles. If you use multiple forms such as simulations and videos in your online training material, then you need to use those same support materials in an instructor-led classroom if you want the learning experience to be equal. Reading a PowerPoint presentation in a conference call should not be valued as equivalent to an instructor-led session in which full instructor engagement is available. Additionally, recording a PowerPoint session and classifying it as e-learning does not change the level of engagement. There is more to consider. Let’s say the training delivery method is electronic, such as a web-based session, but you discover that you are not maintaining the full engagement of the participants. You can bet that your students are trying to multitask. It is scientifically proven that the brain cannot perform multiple complex tasks at the same time. When someone is multitasking, that person is not engaging in those tasks at his or her full potential. Another important consideration is the quality of the instructor conducting the session. If that person has distracting mannerisms, unnatural voice inflection, poor speech or anything else distracting to the participants, it will be a barrier to learning. Not all training is equal, but certification can be a rewarding experience. Proper planning with the right blend of training and resources can yield a measurable return in performance and self-confidence. If you are a decision maker, I encourage you to understand the needs of your employees before selecting a training method. It can dishearten employees who do not certify because of the training method you’ve selected.

New Problem Strange Noise When Starting a Hydraulic Motor By Robert Sheaf, CFPAI/AJPP, CFPE, CFPS, CFPECS, CFPMT, CFPMIP, CFPMMH, CFPMIH, CFPMM, CFC Industrial Training
»
A STEEL MILL reported a strange noise at one of several hydraulic motors driving a roll on a rolling mill. The hydraulic power supply was in the basement of the steel mill. The hydraulic motors on all the driven rolls were bent-axis piston motors with a manifold block mounted on the motor containing two cross post reliefs. The control valves were mounted on valve stands in the basement along with the main pumps. The noise was only on one unit at the roll. Maintenance told me that one hydraulic motor was “gurgling” on start up. After a few minutes it would quite down and seem fine. However, each time the mill was stopped for more than a few minutes, it would happen again. They replaced the motor but still had the same problem. One mechanic thought it might be caused by a new hose they had installed before the noise problem, but it looked like a good assembly. There was no sign of oil leaking from any plumbing connections to the motor, which could allow air to enter when the unit was shut down. Any idea what was causing the noise?

S
olution to the March 2020 problem: Main Relief Valve Keeps Coming Apart in Manifold
This problem was a difficult one to resolve. The manufacturer of the screw-in relief has a great reputation for building a high-quality valve. When checking with the manufacturer, they told the company to check the bottom of the drilled port for the relief on the manifold and that it should contain a small shelf that the cartridge nose would rest on. When they inspected the drilled manifold, they found the OEM of the dumpers had purchased a standard 2-valve manifold without a relief port. They drilled and tapped the port for the relief valve but did not realize the shelf at the bottom (the nose support) was necessary. They replaced the complete manifold with one properly drilled for the relief valve. See illustration.

In marine applications, water can play havoc with fluid reservoirs By Michael Degan, Editor

Saltwater was The fishing vessel was able to continue operations and avoid frequent entering the hydraulic fluid on a 75-meter (245 foot) purse seiner expensive oil replacement. through a seal leak, rendering the net hauler out of commission. Faced Hy-Pro’s V1 and V1S Vac-U-Dry vacuum dehydrators (VUDs) are with frequent fluid exchanges (at a cost of $9,300 plus disposal) and especially compatible with marine applications. The V1 was specially substantial lost profits from downtime for replacement of the seal, the designed for a military application, a littoral combat ship’s pitch control, vessel owner was in desperate need of a solution. said Kevin Close, vice president of sales for Advanced Fluid Systems, Through fluid analysis, the owner found that the 1000-liter (265-gallon) which distributes the V1. reservoir of ISO VGA 32 hydraulic fluid contained 28564 ppm of water. “The challenge with marine is that, because of the saltwater, there are If the ppm could not be reduced below 200, the fluid would inevitably more frequent filtration changeovers,” Close said. “This is common with have to be replaced.

The V1S ran for 10 days, with samples for But the V1 is ideal for numerous marine applications and works for analysis drawn on days 1, 3, 8 and 10. “anything from pitch control to general motor actuator applications.” The V1S reduced the water content in the hydraulic reservoir to a level The V1 is essentially a kidney loop to help keep the oil clean and dry. where the net hauler was functioning properly again even before reaching “It plays on the physical property of water,” said Richard Trent, a Hy-Pro the 150 ppm target. Breaking down the numbers, the V1S removed at least regional sales manager. “Water will turn to vapor at a lower temperature 26.5 liters (7 gallons) of water, and even more depending on ingression. when it’s under vacuum. The goal is to heat the fluid to a temperature of between 140 and 150 degrees F. Then that fluid is exposed to a vacuum of 24 to 25 inches of mercury, and at that temperature and vacuum, Estimated Water Removal Time by Model 100 water will vaporize. The water vapor is pulled off by moving air, which 90 is used to create the vacuum. The lubricant itself falls to the bottom of V3 V5 80 the chamber, where a hydraulic pump pulls it out, pumps it through a 70 V10 particulate filter, and sends it back to the reservoir.” 60 The V1 differs from other dehydrators on the market in two ways, V15 50 Trent said. V20 40 The first thing, “is the amount of air we actually move. You’ve got to V30 30 V45 create the vacuum in the vacuum chamber and still have a high enough 20 V60 air flow to get those vapors out of the vacuum chamber. The fluid is warm 10 coming out of the heaters into the chamber.

have a PLC option, but our opinion is, let’s make a machine that’s simpler for people to troubleshoot than one with a PLC. With ours, you can troubleshoot it and just buy the individual parts that you may need to replace inside the panel from time to time.” Trent said the V1 has many marine applications. It works “anywhere water is getting into a lubricant. Vacuum dehydration will remove not only the free water, but it’s the primary technology that will remove dissolved water as well.” It does this while preserving helpful additives. “Vacuum dehydration has the ability to break the bond between the rust inhibitor and the water molecule so that you’re not running at 100% saturation. You can drive water content down to 20% of saturation, which means now you’ve got a lot of free rust inhibitors that are free to do their job within the fluid itself.” Another marine application of the VUD is on ships, said Mike Flick, Hy-Pro field technical rep. “When a ship is in port, the propeller shaft rests on the seal. The seal then gets crushed a little bit. That allows the water to ingress in and the oil to leak out. The idea is to clean and dry the oil so it doesn’t ruin the hydraulic lubricating equipment or the bearings on the shaft.” The difference between the V1 and other Hy-Pro VUDs is size. “The V1 runs at 1 gallon per minute. It’s for smaller applications. We also make the V1S, which is specifically for ships and has a lower center of gravity. The standard VUD would be for larger reservoirs, maybe 800 or a thousand gallons,” Flick said. Besides the V1 and V1S, Hy-Pro makes eight other models that treat increasing reservoir sizes. But they all work on the same kidney-loop principles. One unwanted result of the process that can occur is the creation of foam, Trent said. “You have to be careful about how you handle the fluid
transitioning into the vacuum in the chamber. When you pull that vapor out, air can go back in, and that can cause foam. “Most of the time foam occurs when a large amount of water comes through and you vaporize all that water at one time. We have a function on our machines called a foam sensor. When it senses the foam, it energizes a valve that opens the vacuum chamber to atmosphere. So it gets an in-rush of air from the atmosphere to knock the foam down. If you’ve got a bad lubricant where the anti-foam additive is gone, then you have to work with the foam, and the foam sensor will allow us to do that too.” The technology’s been around for a long time, Trent said, “but it’s not a technology that a lot of industry is aware of.” Left: Hy-Pro’s V1 vacuum dehydrator Right: Hy-Pro’s V1S vacuum dehydrator

Oilgear Products for Subsea BOP Systems Oilgear recently released two prodOilgear also released a new directional valve ucts for blow-out preventer systems in for BOPs designed for extreme conditions in subsea applications. the deepest ocean floor environments. The Oilgear’s subsea all-hydraulic boosting and regulating system (BARS) needs no electronics or special control features. The BARS unit allows drilling contractors to use the full working pressure in existing subsea accumulators, effectively storing the extra energy required for optimal use of the blow-out preventer (BOP) system. The proprietary intensifier pumps boost the pressure from the surface to a maximum of 7,500 psi to provide accumulator supply pressure. When the BOP control system has a demand for fluid, the high-flow regulator on the BARS unit regulates the pressure back down to the maximum working pressure of the control system. Because the operation of the BARS unit is fully hydraulic, no electrical signals are needed. Once fluid is supplied to the inlet, or consumed from the outlet, the BARS unit will begin to operate until a system equilibrium is created. The benefit for drilling contractors is that the unit maximizes the pressure capacity in accumulators without increasing the pressure of the existing piping and hydraulic system. The BARS unit can be retrofitted onto any BOP stack and is simple to install. It bolts onto the BOP and easily connects with only three hoses. The unit is a fraction of the weight and cost of adding more accumulators. The BARS unit is available in various pressure and flow-rate configurations, and it can accommodate all BOP fluid types.
high-performance SPM valve provides critical function control for subsea BOPs thousands of feet below the ocean surface. The valve is sold as an aftermarket replacement component that can drop into existing BOP platforms and fits into nearly every OEM system available. Oilgear’s engineers designed the SPM valve to operate consistently in extreme subsea conditions. The valve seats are designed with Oilgear’s proprietary hard-seated design. They can withstand higher pressure and more cyclic loading than current SPM valve seats. The unique seat design and high strength of the hard seats allows the SPM to handle water hammer and pressure
spikes from BOP functions. The seats are also strong enough to handle a full 5,000 psi in the pilot circuit. The low crossover flow design has a metered valve opening that reduces interflow out of the vent during shifting, reducing energy and shock in the system when the SPM shifts. The use of electro-polished, corrosion-resistant materials means the valve won’t prematurely corrode in the harsh seawater environment. The one-piece design has fully replaceable poppets, and its seats do not require lapping or special processes to be leak free.

Dear IFPS Associate-
Let's Stay Home
»
DURING THIS UNPRECEDENTED time, the IFPS is making every effort to keep our ship sailing smoothly. However, I ask for your patience with any orders you may place over the next few weeks as state restrictions mandate a modified in-office work schedule. By now, everyone should be very aware to socially distance ourselves from others. To embrace this unfortunate new-norm, the IFPS has instituted a number of new initiatives including a free, Online Study Group for the Hydraulic and Pneumatic Specialists Certifications. This could be a perfect time for you to start preparing for a Certification test or gathering recertification professional development points.

The Challenges of Hydraulics in
By Michael Degan, Editor
As head of Subsea Automation Systems at Bosch Rexroth, Alexandre Orth is fascinated by the ocean. “What fascinated me when I started in this field was: I learned that we know more about space than we do about the ocean depths. . . . The sea floor is as difficult for us as going to the moon.” Orth should know. He designs undersea equipment for marine applications, equipment 18

such as a new subsea valve actuator made to withstand the harsh conditions of the ocean floor with limited maintenance possibilities (see article on page 34). From an engineering standpoint, the challenges associated with subsea equipment are numerous, Orth said. Saltwater, which is very corrosive, is the first problem. Also, down to a depth of about 100 meters where the light reaches, crustaceans such as barnacles can grow in or on the equipment and cause problems. The distance of the equipment from the shore presents challenges. For example, oil and gas
platforms are often situated far from the coast, often by 100 kilometers or more. It is difficult to bring equipment to them, and the logistics are complicated. Some operations can be up to 4000 meters deep with pressures more than 400 times that above the sea. Finally, if something is not working, it is very difficult to “go have a look.” Consequently, the operations must be remotely controlled. Undersea applications must rely completely on the automated systems. “As a control and automation engineer, there is no better challenge than that,” Orth said. But this is where the ruggedness and reliability of fluid power come in. Orth said hydraulics is uniquely suited to the environment and the conditions in which the undersea applications function. “You have extremely heavy loads, and [with hydraulics] you have the advantage of power density. You can increase the hydraulic power and reduce the size of the equipment. When you think about transporting a machine hundreds of kilometers and laying it down on the seabed, you need a big crane [using hydraulics] to do that. “Another advantage is that hydraulics can be integrated with the ambient pressure, so you can use sea pressure, and there’s no need to make a special housing to protect the hydraulic equipment from the high pressure. This reduces the size of the equipment. Normally digital electronics cannot withstand the high pressure; they are damaged by it. They need a special housing with thick walls to withstand the pressure. With hydraulics we don’t have this problem.” In a typical hydraulic system, Orth explained, “there is a tank for the fluid, a pump with controls on top and an actuator. In our case, we open the tank and throw everything inside, and the only thing outside the tank is the actuator itself. So the hydraulic fluid is protecting the hydraulic equipment against the sea conditions. The whole system is swimming in the fluid, and this helps compensate for the high sea pressure. “This tank is a little bit stronger than normal. We use a membrane that lets the seawater pressurize the hydraulic fluid. So the hydraulic fluid is always at least the same pressure as the sea pressure. But we like to have a little overpressure, so our tanks have an added spring on this membrane, increasing the internal pressure. The hydraulic fluid is always 1 or 2 bar above the seawater pressure. And we always have a positive overpressure on the sealing on the outside walls. “The pump only needs to provide the relative pressure, not the absolute pressure.“ Getting projects to the ocean floor has its own problems. The machine is transported by ship, then laid down with special cranes and WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG
winches. Special control systems are needed, unique to the undersea environment. Engineers Orth said, because the sea floor is fixed, but use environmentally friendly fluid in a closed-systhe sea surface is moving. Hydraulic systems tem design to protect the sea environment. This article is based on the episode of the The challenge for the engineers, Orth said, Fluid Power Forum podcast posted on Feb. 3, are also normally used to get the machine to the ocean floor, helping to compensate for “is to think about all this before the equipment 2020.

Operators conduct a controlled descent to protect the machine. A normal descent speed is five meters per second. “The most critical times are at the beginning and the end,” Orth said. “The most control is needed when the machine is submerging below the surface, and then when it approaches the seabed.” With the corrosive effects of saltwater, protecting the hydraulic system is key. The manufacturer could use a special type of stainless steel, but this drives up the cost. Instead, they use normal steel with a special coating that manages the corrosion. “The coating is unique to the subsea environment,” Orth said. “Managing corrosion on the sea surface is more critical than on the sea STANDARD COM PON E NT floor.

Another example of high-reliability design is application of a redundant drive system. “With wind farms,” he said, “you can perform normal maintenance so there is no reason for redundant design.” The control system is another challenging design step. “The challenge with subsea systems is that everything is controlled topside. There’s a lot to be thought of up front because the normal Free Engineering Assistance trial-and-error approach is not possible.” for Custom Designs The designers face stringent requirements about reliability and safety. “We tried industrial electric controls with very low power demand, [but] we decided to stay with automotive electric controls.

IFPE RECAP:
Looking to the Future in an Uncertain Present

MAY 2020
rganizers said it set a registration record, but concerns about the coronavirus hung like a cloud over the 2020 ConExpo/Con-Ag & IFPE trade show, held March 10-13 at the Las Vegas Convention Center.
The International Fluid Power Exposition show ended a day early. It had been scheduled to conclude on Saturday, March 14. But citing increasing travel restrictions, especially affecting international attendees, organizers ended the show on Friday. Even the weather contributed to the damper, as two days of storms passed through Las Vegas, knocking out the city’s usual tepid sunshine. A number of companies pulled out of the show in the weeks before the opening, including some of the biggest in the industry. Parker Hannifin, Eaton, Danfoss and Bosch Rexroth all withdrew their exhibits and stayed home. Other firms that stayed away included Hallite, API Heat Transfer/TTP, and Mack Truck. With growing concerns about COVID-19, show management worked closely with the Las Vegas Convention and Visitors Authority and the Southern Nevada Health District to make sure exhibitors, vendors and attendees were provided with heightened cleaning services and hand sanitizers to help reduce the spread of germs. Organizers also encouraged a no-handshake policy, advising attendees to use fist or elbow bumps when greeting each other. Organizers said registrations for the show totaled more than 130,000 people. At the conclusion of the show, cancellations from international attendees totaled less than 1%. In general, most exhibitors said they experienced slow but steady foot traffic throughout IFPE, which carried on with its purpose: bringing together industry segments in fluid power, power transmission and motion control to display the latest in new technologies and products, share knowledge, network and buy equipment.
WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG
Every three years, IFPE focuses on the latest innovations, product advances and expert insights to equip engineers and manufacturers to increase efficiency, contain costs and improve the performance of their hydraulic and pneumatic systems and applications. According to IFPE Show Chairperson David Price, Global Marketing Manager of HydraForce Inc., “The crowd was much better than expected under the circumstances and, most importantly, the right buyers were on the show floor. We were very pleased with the strong showing from the 300- plus exhibitors at IFPE 2020, and we are looking forward to the 2023 show.” Standout moments of the week included the unveiling of a 3D-printed statue of a female construction worker to acknowledge the growing role of women in the industry. Placed in the Tech Experience area in Silver Lot, the statue stood on a ten-foot base and rose an additional 19 feet high.
The show also saw the first-ever Fluid Power Hour, an IFPE-wide opportunity for extra networking with decision makers and visibility for exhibitors. Other highlights of the week: • U.S. buyer attendance increased 8% from the 2017 show, and total buyer attendance improved by almost 5%. • Overall contractor and producer attendance grew by 14%. • Six out of seven attendees served in a decision-making role. purchased a record-breaking 75,622 tickets for education • Attendees sessions, a 46% increase from the 2017 show.
The next IFPE trade show is scheduled for March 14-18, 2023, in Las Vegas.

Lone Star Fluid Power Action Challenge Draws in 20 Students
»
TWENTY MIDDLE SCHOOL students recently participated in the Lone Star College Cy-Fair at The Cypress Center’s second annual Action Challenge, and a professor there had this to share about the student experience: “The most relevant outcome for the students was that they learned what to think about when redesigning after testing and failure… We took the opportunity to discuss with them the reasons for this and what they could do to improve their design, teamwork, and preparation to be more successful next time.” – Professor Lone Star College Cy-Fair
Many thanks to the National Society of Black Engineers for sponsoring this event. The Fluid Power Action Challenge is an event that allows middle school students to learn how to plan, think critically, work together on a team and compete against each other to solve an engineering problem using fluid power. Students begin the program by learning about the basics of hydraulics and pneumatics. They work in teams as they experiment and
design their own unique machine and compete against their peers at a timed event. The Action Challenge introduces them to careers available in the fluid power industry and creates an environment where failing is OK, because it’s the best way to learn and succeed.

2019 U.S. Fluid Power Product Exports Summary Released
»
U.S. FLUID POWER products exports reached a record high of nearly $6.6 billion in 2019 despite a declining domestic fluid power marketplace and the uncertainty caused by unstable trade policies and tariffs throughout the year. While very little changed in 2019 concerning major trade partners and leading U.S. fluid power product exports, the results of the recently released 2019 Foreign Trade Report reveal consistent industry trends. U.S. fluid power exports in 2019 continued a consistent growth trend over the last 10 years, narrowly surpassing 2018 with 0.2% growth. While our two top U.S. fluid power exports trade partners did switch places, as did Japan and Australia, there wasn’t much change to the top trading partners. The top five partners represent over half of the industry’s exports at 56% while the top ten trading partners represent 73%. The remaining 27% of our exports is divided among 182 other countries. Export data also typically doesn’t show much change when it comes to U.S. exports by fluid power product type. “Parts of actuators and motors” dropped a couple spots, but that is the only change of note. The top five fluid power products represent 60% of all U.S. fluid power product exports, while the top ten represent almost 90%. All the data used to generate the graphs and information above can be found in NFPA’s 2019 Foreign Trade Report, an exclusive benefit of NFPA membership.

Hydraquip Hosts First Fluid Power Action Challenge
Smart Hydraulics. Easy Business. Precise, Flexible and Safe Load-holding valves type CLHC-C
Âť
HYDRAQUIP RECENTLY LAUNCHED their first Fluid Power Action Challenge at The Colorado STEM Academy earlier this year. Eighteen students participated in this middle school competition. The goal of the Action Challenge is not only to introduce students to the concepts of engineering and learning by experimentation, but also to show them the value of teamwork and project management. After learning about hydraulics, pneumatics and the Challenge scenario on Workshop Day in October, student teams spent several weeks prototyping machines that rotate and lift objects while documenting their solutions in their project portfolios. The teams came together again in January and were provided an identical kit of supplies to recreate their unique device and compete against their peers. In addition to sponsoring the event, Hydraquip provided judges that evaluated each of the teams in several categories and kept score as teams used their machines, seeing how many objects they could move in the allowed time. Many thanks and congratulations to Hydraquip for joining the community of Action Challenge Champions that work to support these events.

Meet Fluid Power Scholarship Winner Cole Rickerson By Amy Zignego, Workforce Program Manager, Fluid Power Scholarships
»
THE NFPA EDUCATION and Technology Foundation has awarded $2,000 scholarships to students pursuing fluid power technology fields of study. One of the winners, Cole Rickerson, attends Texas A&M University and is enrolled in the Industrial Distribution Engineering program. We asked Cole about winning the scholarship.
WHAT DOES WINNING A FLUID POWER SCHOLARSHIP MEAN TO YOU? Winning the Fluid Power Scholarship is a huge blessing to me. As a student who is paying through my tuition on my own, this allows me to focus more of my time on my studies instead of working while classes are in session. The scholarship will relieve a huge portion of the stress that incurs with paying my tuition. WHY DID YOU CHOOSE TO LEARN ABOUT FLUID POWER? I chose to study classes related to the fluid power industry because of the relevance to my current job. I currently work for Nalco Water working with increasing pump efficiency, as well as moving water from point A to point B. This scholarship goes hand in hand with what I am currently doing. WHAT ARE YOUR CAREER ASPIRATIONS? WHAT TYPE OF FLUID POWER JOB DO YOU HOPE TO GET AFTER YOU GRADUATE? My current career aspirations are to become an engineer for Nalco Water. I am currently interning for them and I have decided that it would make a great job for me outside of college. Within the company I would like to become a manager of accounts.
The NFPA Foundation’s goal is to help individuals enrolled in high schools, technical colleges, and engineering schools pursue their interests in fluid power. For further information about the program, contact Amy Zignego, Workforce Program Manager, at azignego@nfpa.com.

Inserta® is pleased to announce the upcoming introduction of Duplex Filtration Assemblies for the operation of parallel filters. When one filter needs to be replaced or serviced, the inlet diverter valve is used to select the opposite filter for continuous operation. The assemblies will be provided in inlet and outlet sets. The inlet assembly contains a selector valve, while the outlet assembly contains check valves to prevent back flow through the unselected filter. The captive flanges on both the inlet and outlet assemblies may be rotated to accommodate both vertically and horizontally oriented filter flange patterns. Different size, or even SAE Code, flanges may be provided for filter connections so long as the maximum working pressure of the nominal size assembly is not exceeded. The assemblies may be configured for either bottom or top filter head geometries. Mounting plates are standard. Both the inlet and outlet assemblies provide three degrees of axial and rotational freedom to accommodate manufacturing tolerances in the filter flange pattern locations and mounting planes. The Inserta® Duplex Filtration Assemblies are of steel construction.

new hybrid concept
Subsea factory concept illustration with courtesy of DNV GL
The subsea valve actuator can save costs in electric infrastructure alone (power cable, transformer, frequency converters, etc.) versus electromechanical actuators, for example.
for Actuating Subsea Valves By Alexandre Orth, Head of Subsea Automation Systems, Bosch Rexroth, and Amadeu Placido Neto, Bosch Rexroth Test Engineer
A new deep-sea actuator promises around-the-clock operation with little or no maintenance and no hazards for people or the environment.
34
MAY 2020
B
osch Rexroth’s subsea valve actuator (SVA) provides up to SIL3 safety, consumes up to 75% less energy and is designed for 25 years of operation. The SVA boasts an external pressure 300 bar and is compatible with a saltwater environment, 24-hour operation 365 days a year, and promises a 25-year lifetime with little or no maintenance. Operational safety is especially important for underwater systems that produce oil and gas, to protect people and environments. Additionally, protecting the sea from the pollution that intentional leakage of hydraulic fluid causes is now also a key priority. The SVA uses the best of electromechanics and hydraulics in a compact unit for deep-sea applications. Multiple undersea wells may be controlled from a central location. Each well has its own control facility
or plant. This type of system is known as a “subsea tree.” Each branch controls the production of its respective well via multiple process valves. The process valves are actuated by the SVAs, which in turn, receive their electrical control signals from the actuator control modules. When required, they must safely close the respective process valve in every operating state, even during power failure.
Self-contained axes with a hydrostatic drive The SVA provides an energy-efficient and safe alternative to the previously used hydraulic or electromechanical actuators. SVAs are self-contained modules with their own closed fluid circuit. A variable-speed motor drives a robust hydraulic pump, which generates flow for the cylinder WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG
movements. Without an external power supply, a safety valve with a mechanical spring ensures that the cylinder also changes safely into the fail-safe position if the power fails. The cylinder, which opens and closes the well valve, can also be actuated externally by an underwater robot via an override. All key components of the drive train are installed redundantly. Altogether, SVAs provide safety on four levels with the redundant controls, the fail-safe spring and the intervention options from outside. The benefits are especially clear when the solution is compared with the current state of technology. The vast majority of underwater actuators used around the world are still based on conventional hydraulics. This common structure has proven its durability and long-term safety over the past 50 years. However, operators still want to reduce the effort needed because conventional hydraulics require big, central hydraulic power units above water. These supply the actuators with fluid via lines, known as umbilicals, that can be kilometers long. At a working depth of 3,000 meters, several hundred liters of fluid accumulate in the lines alone. This is in addition to the demand for additional hydraulic accumulators and directional valves required for a complex subsea control module. As the first alternative, equipment suppliers tried to set up electromechanical solutions. These only need to be supplied via power cables and connected to the actuator control modules via a data line. However, because they have no external mechanical intervention options for adjustments, electromechanical solutions have safety-related disadvantages. Due to their lower power density, they also require bigger housings and electrical batteries. The design results in high friction, causing mechanical wear on the power transmission and reducing the required 25-year operating period. For these reasons, electromechanical solutions are at a critical disadvantage for subsea applications when a fail-safe emergency closure is needed.
A cutaway view of the new hybrid subsea valve actuator, which combines electromechanics and electrohydraulics in a compact unit for deep-sea applications.
The subsea valve actuator promises to provide an energy-efficient and safe alternative to traditional hydraulic or electromechanical actuators.
Self-contained industrial axes as a standard
Up to 75 less energy consumption
%
The SVA combines the benefits of both hydraulic and electromechanical solutions and eliminates the existing disadvantages. The decentralized fluid circuit means the topside hydraulic power unit, subsea hydraulic control module and kilometer-long umbilical cords are no longer required for the fluid. The SVAs only require a power supply and a data line, like the electromechanical actuators. WWW.IFPS.ORG • WWW.FLUIDPOWERJOURNAL.COM
Hydraulic pumps generate the flow rate for the wear-resistant hydraulic gear. As a control principle, Rexroth uses a displacement system here, which regulates the flow rate with low friction from out of the rotation speed. This simplifies the design because proportional valves are not required and significantly increases energy efficiency. Compared with the purely electromechanical actuators, SVAs consume up to 75% less power at peak performance. Considering all the actuators used to operate a subsea field properly, the SVA can provide a huge cost saver for the electric infrastructure, such as power cables, transformers, and frequency converters. The motors can be configured considerably smaller with the same adjustment force of the actuators, which in turn saves installation space and costs. As part of its condition monitoring capabilities, built-in sensor technology continuously records the operating states within the actuator and reports them to the higher-level master controller. Trends can then be analyzed, allowing deviations to be identified and solved early.
For more information, visit www.boschrexroth-us.com.
Within the SVA, there are 2 bar of overpressure at every depth because of the redundant pressure compensation system. This prevents the penetration of saltwater and the need for large housings with a pressure-neutral design. Rexroth only uses underwater cables, even within the axis. All electrical components are also encapsulated. Rexroth’s deep-sea specialists used the principle of self-contained axes for industrial applications when developing the SVA. Where required, Bosch Rexroth has made modifications to the components for deep-sea use at depths up to 6,000 meters. The system and core components also meet the special requirements of different classification societies for marine, offshore and subsea use. Working closely with leading equipment suppliers and operators, the SVA developers used the latest simulation technology for the “proof of concept” and built prototypes for field trials. This innovative drive technology combines the best of electromechanics and hydraulics to help ensure safe and reliable conveyance technology on the seafloor, making the vision of an “all subsea factory” a reality sooner.

RG GROUP, a group of distribution and manufacturing companies headquartered in York, Penn., in March announced a partnership with AutoGuide Mobile Robots, a supplier of high-payload autonomous mobile robots (AMRs). AutoGuide’s autonomous mobile tuggers and forklifts are used in industrial and warehouse material handling. The modular products are not manufactured as a retrofit kit to an existing piece of equipment but as a stand-alone platform. Working without limiting infrastructure, a SurePath guidance system deploys vehicles without using magnetic tape or RFID tags. Some models travel up to four miles per hour, while the non-contact collision avoidance system keeps their human counterparts safe. “The addition of AutoGuide Mobile Robots provides a significant new product category to expand our service offerings to both manufacturing and distribution/logistic market segments,” said Rich Freeh, president and CEO of RG Group. “The AutoGuide AMR will add a heavy payload capacity to fill out our expanding industrial automation business segment. We are excited to announce AutoGuide is joining RGIA so we can continue to offer our customer base the premier global brands available today for automation solutions.” “RG Group has been successfully implementing AMR technology, transporting up to 1,000 kg payloads in our respective markets for three years,” said Patrick R. Gross, VP of automation and robotics. “With the addition of AutoGuide as a partner, we will be able to help customers with much heavier payload requirements who are looking to reduce fork truck traffic in their facilities. AutoGuide is already being adopted by some of the largest logistics and automotive organizations in North America. This is a sign to us that we have picked the right long-term partner for our business. AutoGuide has committed to releasing new products in the very near term that will solve big customer challenges, such as automated truck loading and unloading. We are very excited about this new technology and the new partnership.” For additional information, visit www.rg-group.com or contact info@rg-group.com.
