The Value of Connected Hydraulics

By Keaton Holappa, Applications Engineer, Connected Hydraulics & i4.0, Bosch Rexroth Corporation

»

WHEN PEOPLE THINK about hydraulics as a fluid power solution, many picture a hydraulic system from the 1960s and ‘70s that's noisy, hot, and oily, but also robust and powerful. Back in those days, mechanical and electrical valves were used to control a complete system or actuator with pure mechanical and electrical interfaces.

Commonly, these would be mechanically operated or solenoid valves controlled by buttons or switches and relay logic.

Then everything changed. With the rise of Industrial Automation, significant benefits for users of hydraulic equipment began to emerge. Efficiencies increased, production quality improved, and component lifetimes extended, but with this new technology came new problems.

Electronically controlled hydraulic systems are much more difficult to understand, support, and troubleshoot.

Traditionally electrical or mechanical, hydraulic control functionality includes several layers of hydraulic, electric, and software controls. Individuals working with these types of systems require additional knowledge than what is required for older systems. Companies that interact with modern hydraulic systems need access to these skilled individuals. Unfortunately, they are rare and more expensive to employ.

Thankfully, just as Industrial Automation solved some of the problems of traditional hydraulic systems, technology has recently emerged that is solving the problems of modern hydraulic systems. “Connected Industry” or the “Industrial Internet of Things” is the concept that manufacturing facilities, machines, and workers are all connected using computer networking technology, and in many cases, via the internet.

In a world with Connected Industry, digital products and services offer a variety of features that simplify the lives of industrial 4

equipment users. Common features include condition monitoring, self-configuration, and predictive maintenance, to name a few. These are incredibly valuable when applied to hydraulic systems. Individuals interacting with hydraulics don’t need an in-depth understanding of the system to operate and maintain it. Instead, simplified interfaces to the hydraulic system allow operators to focus on production, while maintenance personnel have an easier time planning and performing maintenance tasks.

This is the true value of the Connected Industry for hydraulics, or, Connected Hydraulics. As a manufacturing center that uses hydraulic systems, it can be costly when production is down due to a hydraulic maintenance issue, and perhaps equally costly to employ a skilled team of professionals to properly plan and perform maintenance tasks for this system. In the world of Connected Hydraulics, this is no longer an issue.

What if instead of a large team of experts, a “virtual technician” existed? This virtual technician would constantly examine all data points available in the system and inform the maintenance staff of exactly what and when upcoming maintenance was required for the system. Then, the maintenance team views a step-by-step process in Augmented Reality on how to solve the problem. Downtime could be predicted, planned for, and avoided, yielding massive monetary savings. While this all may seem a bit of a fantasy, these types of systems already exist in some industrial applications. Although we are still many years away from a fully Connected Hydraulics system, there are already early adopters who see the potential and are becoming more competitive in their markets from the benefits. 

High Efficiency Hydraulic Pump-Motors Employing

Partial Stroke Piston Pressurization

Presented by: Thomas Chase, Morse Alumni Distinguished Teaching Professor and Alissa Montzka, Research Assistant Institution: University of Minnesota

»

PURPOSE Most technology utilizing hydraulics involves pumps or motors. However, one of the challenges of hydraulic pump-motors is the issue of energy use when they are run at low output levels or low-displacement power. The Artemis Digital Displacement hydraulic pump has been the “gold standard” when it comes to offsetting low displacement with a high energy efficiency, but the device is expensive and not always the best option for specialized projects in the fluid power industry. The goal of Thomas Chase and his team is to develop an alternative to the Artemis device using hydro-mechanical control.

»

PROGRESS The project includes the use of a two-stage process: the 2D rotary valve pilot stage and the spool valve main stage. The pilot stage employs a 2 degree-of-freedom valve that allows the user to adjust displacement, switching from pilot to tank pressure.

Typically with the use of a variable displacement swashplate, a piston is subjected to high pressure for the entire power stroke. But when utilizing the partial stroke piston pressurization (PSPP) model in the team’s new pump, the piston is subjected to high pressure for only a fraction of the power stroke. The spool translation changes the stroke, ideally reducing compressibility loss when the pump starts the stroke late and the motor ends the stroke early.

With the PSPP, the user sees a reduction in slipper friction and piston friction, plus the valve plate is completely eliminated. With lower displacement in a PSPP pump, the team expects to see a significant increase in efficiency as well as other system components requiring less use, e.g., cooling systems.

Because most hydraulic systems are run at partial power most of the time, having a pump that is extremely efficient even when running at low displacement is beneficial to a lot of applications in fluid power systems like on-road and off-road construction.

»

NEXT STEPS When running the pump at about 0.27 displacement, the newly developed pump measures at approximately 55% efficiency. When the pump is running at 0.60 displacement, it measures at roughly 93% efficiency. With these results in mind, the team confirms they’re on the right track in developing the hydro-mechanical pump-motor that will lead to their final goal. However, despite the team’s satisfaction with the test efficiency rates, here are some of their plans to improve the efficiency going forward: fix the pilot line leakage, set the backlash timing with greater accuracy, and run the pump at a higher pressure rate.

After adding these adjustments, the team can ultimately determine if the use of a PSPP and discrete piston control using mechanical valving will provide the results they anticipate.  WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

AUTOMATED UNLOADING WITH THE RIGHT

CONCEPT

INJECTION MOLDED PARTS CAN HAVE

By Mike Tuohey, Regional Marketing Manager, Americas, Piab USA

SIMPLE, FLAT OR VERY COMPLEX SHAPES. ACCORDINGLY, THE ENDOF-ARM-TOOL (EOAT) MUST BE CONSTRUCTED IN AN AUTOMATIC UNLOADING PROCESS. THE REQUIREMENTS INCREASE IF THE PARTS TO BE REMOVED ARE TO BE CHROMED LATER. PIAB'S NEW DIVISION ROBOTIC GRIPPING SPECIALIZES IN DEVELOPING GRIPPING CONCEPTS FOR THE DIFFERENT LEVELS OF COMPLEXITY. WITH THIS APPROACH, THE OPTIMAL BALANCE BETWEEN QUALITY AND COST REQUIREMENTS CAN BE ACHIEVED FOR EVERY COMPONENT.

14

JUNE 2019

Plastic injection molded parts are used in a wide range of applications, ranging from simple flat geometries to highly complex curved geometries. The aim of manufacturing these components is to maximize the automation of the manufacturing process to minimize cycle times, reduce costs, and ensure consistent quality standards. The automatic unloading of finished components plays an essential role and places high demands on the design of the end-of-arm tools (EOATs).

With the acquisition of both SAS Automation and Feba Automation, Piab combines the best of two worlds of gripper construction and can offer both grippers based on standard

square profiles as well as on the basis of round profiles, depending on the component and the customer's request.

Rectangular profiles are preferably used in simple or flat component geometries, which are removed on the core side. At this form of removal, the demolding of the component from the tool is carried out via ejector systems. For removal, the component can be picked up from the ejector pins or ejector units with simple components, such as suction cups or folding fingers and sprue grippers. A fully automatic removal with sprue separation is possible.

The company’s gripper concept based on round profiles is ideal

especially for complex, geometry-strong components, such as those used in the automotive industry, i.e., for bumpers, which are removed on the cavity half (on the nozzle side). It allows greater flexibility in terms of the positioning of the components on the gripper.

The lower weight of the gripper protects the mechanics of the robot and reduces its susceptibility to interference. Correspondingly, higher payloads or the use of a smaller robot are possible.

"The matrix side gripper carries out the de-molding from the cavity half of the tool. In the meantime, the gripper must actively deform the component via gripper lifting

units and movable vacuum units in order to be able to mold it from the undercuts on the tool side.

In this case, stress whitening or scratches on A-surface of the component (the visible side of the part) must be avoided at all costs, as they continue to be more visible after further process steps, such as painting or galvanizing, and thus usually do not pass quality control processes," explains Rob Dalton, president of Piab Robotic Gripping Division in Xenia, Ohio.

As specialists in matrix-side grippers, Piab developed extensive knowhow to even remove parts with highly complex geometries from the mold without any damage.

A further specific requirement are extractions of components, which have to be galvanized—also known as chromed—later, because any mark and tiny scratches on the chrome surface would be immediately visible. Piab has developed a special gripper for the automated

removal of such injection-molded parts. This gripper docks to the injection molding tool via special centering units. Flocked contour pieces, which correspond to the negative form of the component, take the component carefully and gently. The component is held in the negative mold on gripper fingers that touch the component only on the non-viewing side. In this way, even the most sensitive, already processed components can be handled easily and automatically in consistently high quality.

“Generally, we develop each gripper specifically on the basis of customer needs, the robot type used and the requirements imposed by the component. We work closely with our customers and construct each gripper based on the tool and component data provided to us in the CAD system.

Depending on the size of the gripper, it is fully pre-assembled at our production site in Xenia, then completed and put into operation by our service technicians at the customer's site," describes Dalton of the implementation procedure for all gripper projects. 

Understand the Impact of Your Profit Per Sale Making Sure You’re Dedicating Your Resources to the Right Clients

By Jill J. Johnson, MBA

»

FEW ENTERPRISES TRULY understand the actual profits generated by the individual sales they make. Most metrics for sales effectiveness are monitored by reviewing top line revenue results. Yet the most critical determinant of ongoing business viability is understanding what revenue actually drops to the bottom line after all costs have been taken into account. You must understand what profit is generated by sales to each of your clients. Then consider the benefits and vulnerabilities the cumulative impact these

sales mean to your business. Knowing the breakdown of the profitability by the individual sales to your clients can have a significant impact on your ability to achieve your business goals.

1

UNDERSTAND THE IMPACT OF THE PROFIT PER SALE There are many expenses that go into determining profitability for a company. The same is true for determining the profitability of a sale.

Each sale has multiple components impacting

its final profit. You should consider your total cost of goods sold, including investments in promotion and delivery expenses. Factoring in the costs associated with the staff time required to generate a sale is a must, as well. Unfortunately, few companies consider all these expenses when developing their marketing and sales strategies.

Whether you are working on growing your business or you are struggling financially, the impact of the true profits generated by each individual sale takes on greater importance.

KNOW YOUR PROFIT PER CLIENT Frankly, not all clients are worth the effort to generate the sale. Sometimes your growth goals for your business mean you also are growing beyond clients you have historically served.

This transition period is a very vulnerable point for any enterprise. It is also very stressful because you might be wrong and wind up losing a client that could have provided even more revenue value if you had not been afraid to maximize your relationship.

Carefully study the costs associated with serving each client. Perhaps you have long-term clients you like personally, but if you have not taken the time to explore the costs of the sale, their value to your business may have changed dramatically over the years. Before abandoning these clients, try to identify options to trim your expenses without jeopardizing your quality. But it may be time to move on if they are not generating any real profit for your company.

5

MONITOR INDIVIDUAL CLIENT PROFITABILITY A complete review of the mix of your customers and sources of sales will reveal your potential vulnerabilities if market conditions change. It is not enough in today’s complex and competitive marketplace to look only at your total overall sales. If you have one customer that generates more than one-third of your sales, you are in an extremely vulnerable position if you lose that client to a merger, change of staff, or if it goes out of business. Controlling and monitoring your

client profitability and cost of sales allows you to take corrective action before your business’s survival is at risk. This takes on even greater importance if you are overly dependent on key clients for your profitability.

6

THE IMPACT OF PRICING ON PROFITABILITY A close companion to client profitability is understanding the impact of various pricing strategies on the perceived value of your goods and services, and how they intertwine

3

REVIEW YOUR CUSTOMER SEGMENTS REVENUE Using a target marketing approach to grouping your customers into similar client segments provides you with a more detailed understanding of what is working and what is not. The key to effective target marketing is to focus your sales activities and expenditures toward those type of customers who can best be served by your enterprise, who will stay with you over the long-term and who will generate solid profitability.

4

EVALUATE INDIVIDUAL SALES PROFITABILITY There are two ways of looking at your sales profitability data. One is by the individual clients. The other is by combining clients using some specific target marketing components.

Grouping clients by similar characteristics makes it easier to identify trends in the data that you can use to assess the profitability of each of these major segments.

There are many options for grouping your customers into segments. For a B2B client, you could group them by their industry sector, number of employees, location, etc. For a B2C customer, you could group them by where they live, personal attitudes, age, family size, income level, etc.

If Client Segment A generates solid profits for you, but all of your marketing efforts are being devoted to Client Segment B who are barely breaking even, the choice is obvious. You must retool your marketing and sales activity to attract more prospects from Client Segment A. WWW.IFPS.ORG • WWW.FLUIDPOWERJOURNAL.COM

in attracting the customers who will buy from you. Engaging in discounted pricing strategies often attract customers who are buying from you based on price, not value. If you are in a service-oriented business, this can be a slippery slope. You may get clients who keep you busy, but who do not generate the profits you need to build a sustainable enterprise or build your net worth. It is a delicate balancing act, but one you must realistically consider given your business objectives.

7

THE IMPACT OF STRATEGY ON PROFITS You must also consider the financial consequences of your business direction and your vulnerability to setbacks. This assessment allows you to make better business decisions and to set a more realistic strategic vision for your organization. “Finding a lane” or picking your niche through target marketing must also incorporate a true understanding of the costs of reaching them, as well as their ability to add to your bottom line in a meaningful way.

FINAL THOUGHTS Reviewing the trend information for each of your major client segments is an approach that allows for high impact by revaluating the effectiveness of your sales and marketing efforts. It removes your emotions and relationships with your clients to allow you to be more detached in considering their influence on meeting your business objectives. They no longer become just people you like, but a bigger grouping of customer segments who impact your future costs and business growth. If you are not attracting the kinds of clients generating the profitability to move your enterprise forward, it is time to reconsider all of your sales and marketing efforts. 

THE ROAD TO CERTIFICATION

CERTIFICATION SUCCESS PROFILE AN INTERVIEW WITH WILLIAM HENRIQUES SOUZA IGNACIO, CFPHS, AND LUCIANO LIZARDO DE SOUZA GUIMARÃES, CFPHS.

22

JUNE 2019

William and Luciano from Brazil, two committed individuals who wanted to enrich their fluid power knowledge and then become certified. Together, they signed up for a review training class in the United States, secured visas, and booked airline and housing. Then, the class was canceled! When we learned of this cancellation and their situation, we made immediate arrangements to host the review training session at IFPS Headquarters in Cherry Hill, NJ. Tom Blansett, CFPAI, IFPS Technical Director, was flown in from Michigan to conduct a 2-½ day review training. At the end of the training, Luciano and William took the certification test.

The staff held their breath, along with William and Luciano! After spending time with these two dedicated individuals and learning different things about them both, we were extremely impressed with their fortitude. We were all rooting for them; how could you not?

The result: Not only were William and Luciano elated with their successful results, but the entire staff was thrilled as well. When Susan Apostle, IFPS Logistics Manager, learned that William and Luciano planned to have their first American Thanksgiving in a restaurant, she immediately invited them to her home where she and her family embraced their new Brazilian friends with a home-cooked Thanksgiving tradition, cranberries and all.

Here’s their story."

– Donna Pollander, ACA, IFPS Executive Director

HOW DID YOU FIRST BECOME INVOLVED IN THE FLUID POWER INDUSTRY? William: My first contact was an as Internal Representative at a recycling company while in Technical School. After this, I had a real immersion where I started working as a Maintenance Mechanic inside a metallurgy company, performing several activities related to hydraulics and pneumatics.

Luciano: I became involved in fluid power as a Technical Intern during Technical School at a big steel company with several hydraulic machines.

WHY DID YOU FEEL IT WAS IMPORTANT TO BECOME CERTIFIED IN YOUR POSITION? William: It was very important to support my duties as a Sales Engineer and to empower my career.

Luciano: The certification is a good way to prove your skills. If a professional works in fluid power industry, this certification is good for him.

HOW DID YOU PREPARE PRIOR TO TRAVELING TO THE U.S. AND AFTER YOU ARRIVED THERE? We studied the entire Hydraulic Specialist Study Manual provided by the IFPS, as well as other study materials. Prior to traveling, we found studying through Skype to be more convenient for both of us, and after arriving in the U.S., we studied together in the house where we were staying and participated in a review training session before the test.

WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

WHAT WERE THE STEPS INVOLVED IN OBTAINING YOUR CERTIFICATION IN THE UNITED STATES?

1

UNDERSTANDING IFPS

Luciano has been working at TCT Hidráulica with Mr. João Luiz Amorim, who has years of experience through hydraulics training in Brazil. Amorim has an enormous background related to maintenance practice, as well as a high knowledge of technical sources from the United States.

His dedication in his field has grown with a large technical library including several amazing books, magazines and information from all parts of the world. He told us about the International Fluid Power Society and its certification programs, and we motivated ourselves for the challenge.

2

Top: William and Luciano enjoyed their first Thanksgiving dinner in the home of Susan and Nick Apostle.

Left: Adele Kayser, Donna Pollander, Susan Apostle, William Ignacio and Luciano Guimarães

PLANNING TO STUDY

We earned a degree in Mechanical Engineering together, and after our graduation, we decided to start studying together.

We studied for the certification exam for at least 6 months every night during the week and some weekends too.

Even though we live 4 miles from each other, we decided to study through Skype. It was more convenient for each of us, and it is a really good idea for other people as well.

3

PREPARING FOR TRAVEL

We scheduled our vacations to coincide with the best test date available. After this, we booked the plane tickets and a home in Philadelphia, PA, close to the review training and test location.

4

TAKING THE TEST

We participated in a review training session for 2-½ days, and on the third day, we took the test.

CERTIFICATION EMPOWERS OPPORTUNITY

WOULD YOU ENCOURAGE OTHERS TO BECOME CERTIFIED? AND WHY? We encourage all professionals who work with fluid power to become certified. Certification is very serious, and the manuals created by the IFPS with Tom Blansett, CFPAI, have a good methodology for passing the information along in an easy-to-understand approach, thus you take in more knowledge and skills. Plus, the certification is widely recognized in all countries, creating new opportunities for the certified professionals.

WWW.IFPS.ORG • WWW.FLUIDPOWERJOURNAL.COM

HOW HAS YOUR CERTIFICATION HELPED IN YOUR CURRENT ROLE IN WAYS YOU DID NOT ANTICIPATE? The certification process has provided us with a lot of knowledge about hydraulics and created new opportunities in the companies where we work. 

With certification for Hydraulics, Pneumatics and Electronic Controls Professionals, the International Fluid Power Society strengthens and advances professional careers in the fluid power workforce through our work in education, training, and certification. The IFPS is committed to promoting the advancement of technology and professionalism of the fluid power & motion control industry through Training, Education, and CERTIFICATION.

This year, 52 teams made up of over 200 local middle school students worked to design and build a fluid power mechanism in three hours before competing against each other in a timed event. The goal was to see how many objects each team’s fluid power mechanism could pick up from one platform, rotate, and place on another platform in a two-minute period.

Event sponsors Eaton Corporation, FORCE America, Price Engineering, and Waukesha County Technical College (WCTC) also provided six teams of engineers to evaluate the students’ mechanisms and present awards in five categories.

Starting this year, the Action Challenge is also part of a new, larger education pathway that the NFPA debuted in Waukesha, the

NFPA Curriculum Grant Awarded to University of Missouri

»

THE NFPA EDUCATION and Technology Foundation has awarded a $25,000 Curriculum Grant to the University of Missouri for a project titled “Fluid Power Case Study Development.” The project will be aimed at developing three dynamical case studies to supplement the Fluid Power System Dynamics and Control mini-book. The three case studies will include robotics, aircraft, and excavators. All three case studies will involve three components: system analysis, design, and control.

The Fluid Power System Dynamics and Control mini-book, written by William Durfee, Zongxuan Sun, and James Van de Ven in the Department of Mechanical Engineering at the University of Minnesota, attempts to combine very practical topics with more theoretical aspects of fluid power systems design. A number of calculation examples exist in the book, such as power calculations, fluid bulk modulus estimates, and Reynolds number evaluations.

However, the mini-book does not have a case study where all of these things come together to build a system that is For further information used in the real world. on NFPA’s Curriculum The goals of the proj- Grant program, contact ect are to develop three Carrie Tatman Schwartz case studies that incor- at (414) 778-3347 or porate the existing text ctschwartz@nfpa.com. and to show students how to implement the equations in a larger scope. The direct impact will be to make the mini-book more applicable to the practicing engineer and the inquiring student. In a sense, it will provide the student with a capstone experience for learning.

Through its Curriculum Grant Program, the NFPA Foundation awards grants to universities to develop, replicate, or disseminate high-quality, high-impact undergraduate level fluid power curriculum. The program objective is to create awareness and engage undergraduate engineering students in fluid power, and engage engineering faculty in the development and teaching of fluid power.

So far, three curriculum grants have been awarded to professors at Lawrence Technological University, Ohio University, and Western Michigan University. The resulting curriculum has been posted in the Fluid Power Curriculum resource library and is available to any university professor who would like to teach fluid power to undergraduate mechanical engineering students.

CASE STUDY

BUCKET TRUCK IDLE REDUCTION FOR PG&E

By Jill Santos, Marketing Director, Duryea Technologies

THE PROBLEM In conventional utility service trucks, the buckets, outriggers, and other accessory loads require power from a parked vehicle’s engine for an average of 4-5 hours per day while workers maintain power lines. The remainder of operational hours are typically spent on the road.

According to the EPA, a work vehicle with a weight classification of 7-8 tons will emit an average of 5.5 grams of NOx and 152 grams of CO per hour,1 as well as consume 0.85 gallons of fuel per hour while idling.2

50

JUNE 2019

Duryea supplied the right BLDC electrohydraulic motor solution for Pacific Gas and Electric’s Hybrid Fleet Program.

This issue is especially critical in California, where, in addition to having stringent air quality standards, fuel prices are consistently amongst the nation’s highest.3 PG&E, one of the nation’s largest utilities, has invested in new solutions to help its California fleets reduce emissions4 and operating costs. Its initial efforts included procurement of over 800 hybrid bucket trucks sourced from a major commercial work truck OEM and built to its specifications.

SAME HYDRAULIC PERFORMANCE, LESS FUEL 36V SolidSlot Triple Stack BLDC Motor with Pump

Duryea Low-Voltage Electro-Hydraulic Power Unit

THE CHALLENGE In the hybrid fleet, an electro-hydraulic power unit must efficiently power the truck’s accessory loads while the engine remains off during power line work.

To prevent quick depletion of the low-voltage LiFePO4 battery pack, careful selection of the motor for the electro-hydraulic power unit was critical.

Duryea designed its line of SolidSlot brushless motors to maximize performance at low voltage. These motors are field-proven for idle-reduction and other batterypowered applications. The winding-free stator architecture is durable and efficient.

• 36V nominal, 270A • 24V (2,700rpm) • 11.3kW (15HP) • 12V (1,300rpm) • Flow up to 8pgm • Operated at 42V, 24V, and 12V with • Pressure up to 3,000psi LiFePO4 battery • 36V (4,000rpm) • 8 gpm Other Standard Options Available or Engineered-to-Order Visit www.duryeatechnologies.com or call 484-277-7137 for more information.

ANNUAL SAVINGS* *Estimates based on EPA and Office of Energy Efficiency and Renewable Energy data and the following assumptions:

THE SOLUTION The OEM’s hybrid system packager chose a Duryea SolidSlot® Triple Stack 36V motor with integrated Duryea electronics coupled to an industry-standard 7cc SAE A 2 Bolt 5/8-9T spline gear pump. This yielded the most efficient and power-dense electro-hydraulic power unit available for the application. 

• 4 hours a day of line work per day while the engine remains off • 260 days of operation per year • A fleet size of 800 bucket trucks • Average gas price of $3.25/g

Toggle mechanisms are used where high locking forces are required. Die casting machines, injection molding machines, and coining machines all make use of toggle mechanisms. There Fig. 3-5 A Cylinder Used to Operate a Toggle Mechanism are three methods of creating toggle force. They are single lever, For a single lever the upward force of the toggle can be calculated from the tangent of the angle double-lever anchored, and double-lever scissors.

the toggle reaches the vertical overcenter position, the cylinder must be mounted so that its axis is perpendicular to the toggle when the toggle is at the overcenter point. If the cylinder is not perpendicular when the toggle is at the overcenter point, it will be acting at an angle to the load and its thrust into the toggle will be reduced.

Trelleborg Launches Extrusion-Resistant Elastomer Seal for Demanding Static High Temperature High Pressure Oil & Gas Sealing Environments

»

TRELLEBORG SEALING SOLUTIONS announces the launch of the new XploR™ S-Seal and XploR™ FS-Seal that have been developed for demanding high pressure sealing environments, such as those found in oil & gas down hole tool applications.

Combining the benefits of integral support components with the flexibility of an elastomer seal, the XploR™ S-Seal and XploR™ FS-Seal are custom-engineered, spring-energized seals that offer the maximum extrusion resistance necessary for demanding high temperature and high-pressure (HTHP) sealing environments within oilfield applications.

Sealing is achieved by controlled deformation of the elastomer element. Optimal stress distribution throughout the elastomer body is modeled through finite element analysis (FEA) to ensure high performance sealing as well as long seal life. Extrusion resistance is created when the specially designed spring provides support to the rubber, but the seal is still flexible enough to allow easy installation.

The S-Seal and FS-Seal can withstand pressures up to 103.4 MPa (15,000 psi) and temperatures up to +177 °C (+350 °F). The seal materials are certified to NORSOK, NACE, API and Total standards. www.oilandgas-seals.com

Transforming OUR THINKING ABOUT: ENERGY UNITS AND THE COST OF CONTROL

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

DRIVING WITH THE BRAKES ON

I had a friend in college who lived in the city and was accustomed to driving aggressively in city traffic. He had been complaining about the fact that the brake pads on his car did not last very long and he thought the dealer might be selling him inferior products. One day, as I was driving behind him, I noticed that his brake light never went out. When I asked him about that, I found out that he drove with one foot on the accelerator and one foot on the brake. This provided great response time when doing the “bob and weave” in traffic, but did nothing to provide long life for the brake pads or improve 56

his fuel mileage. There was a direct cost to his control system in the form of increased maintenance and fuel charges.

We are taught that there are three things that we control in our fluid power systems: flow, direction, and pressure. Of these three, directional control has the least impact on energy.

It is usually understood that flow is required for velocity and pressure is required for force.

We tend to separate flow and pressure in our thinking and design as though flow control is the only requirement for velocity. We need to understand that velocity control is power

control. The velocity of a load, whether angular or linear, requires both pressure and flow, or in other words, power.

There is a certain quantity and flow rate of energy units that must be supplied to an actuator in order to make it move to do work at a specified rate. With pneumatics, these units are compressible while the hydraulic units are relatively incompressible. In both cases, a volume of pressurized units must be used to move an actuator. Once direction is determined, it is the flow rate and pressure that determine the amount of power directed to an actuator.

WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

Hydraulically, with a fixed displacement pump that has been sized to control one actuator, the motor or cylinder velocity is fixed and only the pressure varies with the load. There is a higher pressure for acceleration, and then a lower pressure to maintain velocity. With both pneumatics and hydraulics, the available pressure must be set higher than the pressure for velocity in order to accelerate the load. Once the target velocity is reached, some type of power limiting must be employed to limit velocity.

When there are multiple actuators under varying loads, or with a single actuator with varying loads and velocities, the energy source—be it an air compressor, an accumulator, or a pump— must provide the needs of the actuator with the greatest pressure requirement.

Consequently, each actuator must have its own velocity control. The most common way to control the velocity is to use restrictive orifice type flow controls. The orifice is considered the means to limit the flow, which it does, but only because of the pressure loss. The power directed to the actuator is a combination of flow and pressure. We know we need the flow and so it is assumed that the only adjustment to the power is to reduce the pressure. The net result is that we design our fluid power systems to be

controlled like my friend’s car. There is more power available than is required to do the work and so we “drive with the brakes on.”

A restrictive power control in a circuit could be a needle valve, a flow control, a pressure

compensated flow control, or a pressure reducing valve. A proportional directional valve and a servo valve are also restrictive power controls as they are simply electrically controlled variable orifices, and are, by definition, energy consumers. With all of these, there is more energy upstream of the restriction than is required downstream and the excess energy is consumed by the frictional loss through the orifice. For many of us, this is understood to be simply the cost of control.

The Variable Displacement Transformer (VDT) replaces the restrictive power controls when there is a variable flow source. This could be a variable displacement pump, an accumulator, or an air receiver. The VDT provides the necessary resistance at the outlet of the actuator, not as a restriction, but as energy units that drive the transformer. One outlet of the VDT directs regenerated flow to the actuator inlet at source pressure, while the other outlet directs flow to low pressure, either atmosphere or the reservoir.

The energy units drawn from the source are only those needed to power the load.

For example, compare the velocity control by a pressure compensated flow control (PCFC) (Fig 1) with velocity control by a VDT (See Fig 2 on next page). The power source is a pressure

The common PCFC limits the power to the motor by adding a resistive load (putting the brakes on) of 9.95 MPa. The excess energy units are dissipated as heat. The pump supplies the full 77.5 lpm at 20 MPa, consuming about 26 kW. Using the VDT (Fig 2) the same effective pressure is needed but it is obtained differently. A resistive load of 9.95 MPa is applied as the 77.5 lpm exhausts from the motor. Instead of dissipating the resistive energy as heat, the flow and pressure are used to drive the transformer, directing 38.54 lpm to join the flow from the

pump. The pump de-strokes, supplying only 38.96 lpm at 20 MPa, about 13 kW; precisely the flow of energy units needed by the motor.

In this application, the VDT provided velocity control without wasting energy.

It is time to think differently and stop driving with our feet on the brakes. ď Ź

Clean Break, Flat Face, or Double Shut Off?

HOW do you know which fluid connector to use for your application?

By Jan Abel, Senior Marketing Communications Manager – North America, Staubli Corporation

Quick release couplings should provide an easy-to-use, fast and reliable method of connection and disconnection that performs faultlessly through many connection cycles.

Although most connectors are designed to be leak-free both in the connected and disconnected state, many specific applications also need to guarantee no spillage at all (for example, connectors used in cooling circuits for electronics or circuits containing hazardous substances). Other applications in less sensitive environments or on circuits containing harmless materials allow for a limited amount of spillage on disconnection.

Frequently circuits may need to be connected with fluid left in the line, avoiding the time and cost of purging the system. Other applications need to maintain the integrity of the circuit, preventing any ingress of air or contaminants. Fortunately, there are designs of quick connectors that satisfy each of these diverse and challenging requirements.

Spillage is often a misunderstood feature of quick connectors. A double shut off design 60

JUNE 2019

connector will not prevent a limited amount of spillage on disconnection. This is due to the gap between the valve on each side of the connector (plug and socket); whatever liquid or gas occupies the space between the valves will be the volume spilled on disconnection. For many applications even this limited degree of spillage would be unacceptable and a quick connector that avoids this problem completely is required.

FLAT FACE CONNECTORS PROVIDE THE SOLUTION. Flat face connectors are designed to ensure that the plug and socket faces match together closely. There is no space between them for any liquid or gas to be retained, and consequently, no spillage occurs on connection and disconnection. This type of connector without any space between plug and socket can be more difficult to connect than the double shut off version. However, there are several ways of overcoming this by modifying the internal design of the connector, such as the flat face connectors, rendering it as easy to connect as double shut off versions.

Flat face connectors also maintain circuit integrity on connection and disconnection. The close fit between plug and socket faces removes any space for air or other contaminants to enter the circuit, even when connecting or disconnecting with fluid left in the line.

Single shut off couplings are typically used on compressed air circuits where complete depressurization of the tool side is required to ensure safety, as well as for those circuits where a completely unvalved system is required.

The facility to make a connection with fluid left in the line brings major advantages to many applications where normally the circuit would need to be drained or purged prior to disconnection, then re-pressurized/re-filled afterwards.

Typical applications range from the brake lines on F1 Race Cars and the quick replacement of radiators on military vehicles to robot arm tool changers in the automotive sector and mold connections on injection molding machines.

There are many factors that may determine the type of connector selected. These include: the space envelope available, whether the WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

connection is made manually or automatically, mechanical considerations such as temperature, pressure, frequency of operation, and how quickly the connection must be made.

Many hydraulic circuits may retain residual pressure in the circuit after the planned operation has been completed. This can cause significant problems with connecting especially where standard hydraulic connectors have been used. Standard connectors do not incorporate a pressure relief mechanism that will depressurize the circuit to allow connection to be made easily and securely.

HYDRAULIC FLANGES AND COMPONENTS HYDRAULIC FLANGES AND COMPONENTS AND COMPONENTS "Serving Industry for 57 years"

THERE ARE RANGES OF CONNECTORS AVAILABLE WITH IN-BUILT PRESSURE RELIEF SYSTEMS PROVIDING THE SOLUTION. A central relief valve automatically opens on connection, safely releasing the volume of fluid necessary to allow the backward movement of the valve, permitting easy connection.

The connector is undamaged and the circuit integrity is maintained.

Selecting the appropriate quick connector calls for evaluation of many parameters in the planned application, which requires experienced engineers who are trained to fully consider all aspects of the applications and are skilled in evaluating the combination of requirements. They will provide advice from the design stage onwards on the most suitable connection solution for any application to ensure excellent performance, long-term reliability, and minimal maintenance. 

If positive hydraulic locking systems and actuators had middle names, they would be “Productivity” and “Safety.” In this article, we’ll explore the distinctive features of positive hydraulic locking systems and actuators, as well as their unique capabilities.

HOW DOES A HYDRAULIC ACTUATOR WORK?

A hydraulic actuator is a cylinder or fluid motor that uses hydraulic power to control or move a mechanical device or system with either linear or rotary motion. It requires a directional control signal from a valve, and a hydraulic source of 64

energy. Since fluid pressure is highly non-compressible, it can be transmitted instantly and can hold force or torque constant without needing more fluid or pressure. It is especially effective for large forces and high speeds.

HYDRAULIC LOCKING SYSTEMS

Typical locking systems lock when power is applied Hydraulic cylinders use liquid as their energy source, which is non-compressible. There are two main types of cylinders: spring or gravity return (with liquid on one side of a piston, and a spring or weight supplying energy on the other), or double-acting (liquid on both sides, one side with higher pressure to actuate the valve, opening or closing it).

VE

Hydraulic locking cylinders typically have emergency stop or “e-stop” features designed to go into effect when power is lost. These locking systems can feature a mechanical lock manually set at a particular location along a rod, or an automatic locking feature, or both.

Static applications (during loss of power, the lock prevents machinery from falling on operators and equipment): In some locking systems, when the pressure is cut, a piston rod passes through a cartridge and internal springs push on an over-the-center mechanism to lock the piston. The mechanism clamps the piston rod, holding the cylinder.

Dynamic applications (stopping the movement of machinery): In spring-loaded locking devices, the spring’s release allows movement of a piston. Piston displacement in turn allows clamping into a locked position.

INSPECTION VEHICLES: ACTUATOR + BEAR-LOC POSITIVE LOCKING SYSTEM From the Super Bowl to the nation’s borders, inspection vehicles are in demand. You’ve probably seen them—maybe even been a passenger—as the x-ray toting mechanical arm of an inspection vehicle passes over other vehicles of all shapes and sizes. Inspection vehicles obviously serve areas where security is a critical need. Chances are the hydraulic actuator that safely lifts and locks the inspecting arm is a York Precision actuator and Bear-Loc. In preparation for the 2019 Super Bowl LIII in Atlanta, Customs and Border Protection (CBP), a division of Homeland Security, actively scanned all vehicles entering the stadium. The York Precision hydraulic actuator moved the inspection arm, and the Bear-Loc assured that the inspection arm did not drop, protecting both persons and vehicles, and allowing the inspection vehicle to successfully complete its mission.

HYDRAULIC PRESS: BEAR-LOC POSITIVE LOCKING SYSTEM The presses in plastics injection molding machines produce the vinyl parts of the vehicles we all drive.

Tragedy strikes if a press brake fails because it can crush and kill its operator. If a press brake relies on hydraulic pressure to remain locked, loss of pressure represents a life-threatening danger. Safety issues with this mission-critical manufacturing process can mean costly fines, perhaps even close down operations.

That could never happen with the Bear-Loc positive locking system because it locks when pressure is removed. Whether pressure is lost on command or by accident, the Bear-Loc engages automatically, providing a reliable, positive, fail-safe lock. Workers can safely operate and maintain the presses.

for the rod to be stroked with minimal resistance.

Load capacities are determined by three factors: diameter of the rod, amount of pressure used to release the lock, and length of the lock.

APPLICATIONS THAT BENEFIT FROM POSITIVE LOCKING

Virtually any application that requires linear force can benefit from the use of a hydraulic cylinder system, and its strength and efficiency are unmatched by any other system. For example, a Bear-Loc and actuator can have pulling or holding power up to 4 million pounds and an operating pressure of up to 5,000 psi. Standing or static applications can range from presses that do injection molding or forging to compactors to testing such as fatigue and flight or aerodynamic simulation. Mobile applications can include inspection vehicles, construction and mining equipment, and more.

To better understand the power and safety features of the positive locking system, let’s look at a few case studies with varying conditions below.

AUTOMOTIVE CRASH TEST WALL: BEAR-LOC POSITIVE LOCKING SYSTEM It’s a scene nobody ever wants to see: a fully loaded 80,000-pound tractor trailer hurtling straight at you and your vehicle.

With its crash test wall, a leading U.S. automaker recreates the scene using crash dummies.

Their rigorous vehicle testing saves countless lives. Of course, the effectiveness of the test requires that the crash wall doesn’t budge. What keeps the crash wall from moving? York Precision’s Bear-Locs.

Four Bear-Locs were installed 30 years ago.

Recently, the customer purchased a fifth BearLoc to serve as a “round Robin” unit to further extend product life. We asked the lead engineer to explain: Why Bear Locs? “The need was for large holding power. We also like Bear-Locs’ fail-safe reliability. The infinitely variable position makes it easy to adapt to different projects. The moveable section of the wall has 90° impact and can turn 30° in either direction, then lock into place.”

He adds that the original engineering team who specified the locks, likely chose Bear-Locs over mechanical pinning.

BASIC VACUUM PUMP SELECTION

By Daniel Pascoe, President, Davasol Inc.

There are many factors to consider when selecting a vacuum pump.

This article explains the fundamental differences between three common vacuum pump technologies and offers the user a better understanding of those differences.

More often than not, a vacuum user will replace an existing vacuum pump with the exact same type of pump they have used before. Of course, if this vacuum pump works, then all is well, right? Possibly. However, just because the vacuum pump works for the application doesn’t necessarily mean that was the best pump choice.

The age-old saying “If it’s not broken, don’t fix it” is a common route to take, and understandably so.

But if you have the opportunity to improve your system, due to a new installation or faulty pump replacement, then this is the time to get a better understanding of what is actually required of the new pumping equipment.

Let’s compare some obvious pump technologies with each other based on typical performance metrics, as well as the comparative advantages and disadvantages of using one type of pump over another.

FIG. 1

ROTARY SLIDING VANE

In general industry, rotary sliding vane pumps, as shown in Figure 1 and Figure 2, are very popular, offering the user a good vacuum flow choice ranging from only 1CFM to beyond 1000CFM. There are two fundamental choices of rotary sliding vane pumps: oil lubricated (Figure 1) and oil free (Figure 2).

This description is self-explanatory, but one should be chosen over the other for one primary reason. If you need a higher vacuum level, then choose an oil lubricated pump. If you don’t need a high vacuum level and 27"Hg (which is the same as -90kPa, 100mbar(a), 76Torr, or 76mmHg) is adequate, then do not use a lubricated pump.

You might ask why don’t you use a pump that is capable of a high vacuum level, but use it at a lower one?

A typical oiled vacuum pump requires a higher vacuum level to stay lubricated. Oil is “pulled” through the vacuum pump under the vacuum. Therefore, if you are using an oiled pump at a consistently low vacuum, particularly below 20"Hg, lubrication of the pump will be poor, possibly resulting in damage or even seizure.

Another reason is that at a lower vacuum level, an oiled pump could possibly start to “smoke” from the exhaust. This is because the amount of air passing through the pump at a low vacuum level is greater than what the pump’s internal air/oil separator is rated for. Consequently, excessive oil vapor is forced through the filter and creates an oil mist or smoke at the pump exhaust.

Just because you found an old oiled pump that isn’t being used doesn’t mean it should be. Understand what vacuum level you will generate before selecting a pump.

Don’t forget that it’s not the pump that determines the final vacuum level, it’s the application. If your application is sealed or dead headed without any external leaks from the atmosphere, then the pump being used will generate its maximum design vacuum level. However, if your system is not airtight—and most aren’t, such as vacuum cup lifting of cardboard cartons—then the pump may not reach its final design vacuum level.

If a vacuum system is not generating as high a vacuum level as it was the day before, it’s rarely the fault of the pump. Any air entering the vacuum system will decrease the final vacuum level being pumped down.

So rotary vane pumps—oil free models (not lubricated)—can be used in the majority of applications requiring a 20-27"Hg vacuum degree. Some examples include vacuum cup lifting, paper sheet conveying, end-of-arm vacuum grippers, universal vacuum tooling, and carton palletizing.

Oiled or lubricated vacuum pumps should be selected for applications where a higher vacuum level is needed, such as vacuum packaging of meats, cheese packaging, vacuum packed foods and similar products, degassing of liquids, adhesive curing, vacuum clamping, vacuum plastination, and vacuum molding. A typical maximum vacuum level of an oil lubricated rotary vane pump would be in excess of 29"Hg. However, using "Hg as the measurement unit is not appropriate as this is a differential vacuum level measurement. In

FIG. 2

WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

higher vacuum level applications, an absolute scale such as mmHg or mbar(a) should be used. Most oil lubricated models will achieve an absolute pressure of 0.5mmHG or 0.5Torr. Some models, designed specifically for high vacuum process applications, achieve absolute pressure in the region of 1x10-2mmHg (0.01mmHg).

DIAPHRAGM PUMPS

Diaphragm pumps, as shown in Figure 3, are normally associated with lower flow vacuum applications, such as standalone medical devices or dental surgeries. Although able to generate vacuum levels in the region of 28.5"Hg, they have a lower flow rate capability, compared to rotary vane pumps, topping out at about 4-5CFM. This is due to the oscillating pumping motion of the diaphragm. A rotary vane pump can spin incredibly fast and has a high surface speed (flow rate) at the vane tip. The reciprocating nature of a diaphragm pump might also be undesirable to the user in respect to the pulsating sound emitted.

However, many DC motor diaphragm pumps are ideal for mobile equipment as well as low voltage standalone machinery. The compact size of the diaphragm pump and DC motor option lends itself to mobile equipment in particular. The diaphragm membrane and pump head is available in a host of materials to aid the user application. Diaphragm pumps are often used in gas sampling applications where the pump “sucks” air in, then “blows” it out to be analyzed or tested with zero contamination of the media. This is not possible with rotary vane pumps due to oil contamination and vane wear particulates in oiled and dry pumps respectively.

REGENERATIVE BLOWERS

Regenerative blowers, as shown in Figure 4 and Figure 5, sometimes referred to as side-channel blowers, particularly in Europe, offer very large vacuum flow rates per kW motor power used compared to rotary vane pumps due to the high-speed impeller design. However, the final vacuum level achieved could be regarded as poor by some, particularly compared to diaphragm and rotary vane pumps.

Yet, the vacuum level is certainly not as crucial in vacuum lifting and material transfer applications as the vacuum level does not have to be very high. A single-stage regenerative blower as shown in Figure 4, has a typical maximum vacuum level of about 6-8"Hg, although some manufacturers offer 2- or 3-stage models with final vacuum levels in excess of 21"Hg. Figure 4 and Figure 5 show a single and a 2-stage model respectively. Notice the position of the exhaust port, which visually indicates whether the pump is single or 2-stage.

Regenerative blowers offer an operation that is virtually maintenance free except for the occasional bearing changes. When used in conjunction with the correct accessories, such as an inlet filter and vacuum relief valve, which bleeds air into the blower inlet to prevent “over vacuum,” these units offer many years of service. It is important to remember that just because a blower can generate a vacuum of 18"Hg does not mean it’s designed to do so.  This article is intended as a general guide and as with any industrial application involving machinery choice, independent professional advice should be sought to ensure correct selection and installation.

Founder of Aerospace Giant Invests in PIRTEK Orlando

»

ROBERT KHOURY, co-founder and retired CEO of B/E Aerospace, Inc., acquired PIRTEK Orlando in February and has appointed his former director of operations to run the longtime Service & Supply Center.

“We’re very excited about this business and we’re looking forward to expanding it here,” said Walter Alfaro, general manager, who will be running PIRTEK Orlando’s day-to-day operations at 1820 S. Division Ave. “Companies that use hydraulic equipment benefit from our service regardless of economic conditions, making this business stable and largely recession proof.”

The PIRTEK center has been in Orlando for 16 years.

Like Khoury, Alfaro comes to PIRTEK from B/E Aerospace, a $4.2 billion company where he served as director of operations and director of facilities during his 24 years there. Alfaro’s tenure at B/E Aerospace entailed supervision of 120 employees, oversight of maintenance, and management of an area that included a 157,000 square-foot equipment facility. Much of the equipment under his supervision contained hydraulic elements.

Among the center’s prominent regular customers are such area attractions as SeaWorld, as well as contractors involved in large-scale roadway construction, Alfaro said. “They’ve been very happy with our service and with our presence here,” he said. “It’s been extremely positive working with them.”

The only franchise brand of its kind in the United States, PIRTEK USA specializes in hydraulic and industrial hose services. PIRTEK technicians at locations throughout the country are available 24/7 to provide onsite repairs to hydraulic and industrial hoses. PIRTEK boasts more than 400 franchise locations in 23 countries around the world, including 84 in the United States. www.pirtekusa.com
