PREPARING FOR

SUCCESS

The Hydraulic Specialist Certification Study Manual Update

By Denis Poirier, Jr., CFPAI/AJPP, CFPS, CFPCC, CFPHS, CFPIHM, Vice President of Certification, The Eaton Corporation – Hydraulics Group

A

dvancements in materials and manufacturing combined with the integration of electronics and software have made the hydraulics industry more complicated than ever before.

It can be a challenge identifying hydraulic professionals with the appropriate knowledge base for the tasks which lie ahead. Successful completion of the International Fluid Power Society’s Hydraulic Specialist fluid power certification can assist in this process. As an industry leader, in third-party certification, an IFPS fluid power certification is not just an individual achievement, but it communicates to others within the fluid power industry a certain level of competence.

Just as the process of applying fluid power has changed, so has our knowledge of how people learn. Put simply, not everyone responds to the same material in the same way. For example, some adults prefer to read in a typical textbook fashion, that is, they respond to the action of turning pages, using a highlighter, and writing notes by hand. Others prefer reading and making notes with an electronic document. In both cases, the transfer of information [the learning process] is limited by an individual’s ability to apply what they have learned from a single source of information; in this case, what they read. For many, this is the least effective method for learning.

IN RESPONSE TO THE CHALLENGES POSED BY SINGLE-SOURCE DELIVERY METHODS, THE IFPS IS PROUD TO OFFER ADDITIONAL PRODUCTS TO ENHANCE THE LEARNING PROCESS.

ANIMATED HYDRAULIC CIRCUITS

The first of which is the creation of animated hydraulic circuits. In this offering, every circuit in the Hydraulic Specialist Study Manual is displayed in color. Additionally, each schematic is animated showing the path of fluid flow and includes notes (bullet points), but is not narrated. These schematics can be purchased as one complete package and used in conjunction with the Hydraulic Specialist Study Manual to enrich the learning experience by bringing the schematics to life.

INTERACTIVE STUDY MANUAL

If having control over an immersed learning environment is more your style, then the Hydraulic Specialist Interactive Study Manual is for you. This fully interactive self-paced learning system uses audio narration in conjunction with animated schematics to walk you through the Hydraulic Specialist Study Manual one outcome at a time. Developed with the e-learning user in mind, this program appeals to the multisensory learner and can be used in conjunction with a printed study manual to expand on the information provided in text. Interactive practice tests and quizzes are also included.

INSTRUCTOR TRAINING SESSION

If those options do not support your style learning, another option would be to attend an instructor-led review session. This environment appeals to the maximum number of senses and works well for the majority of all learners. There are visual, textile, and audio stimulation. Additionally, you work with an Accredited Instructor, can ask questions, work through practice exams, and interact with others who may share the same experiences and challenges that you do.

This is typically the most effective method for knowledge transfer, and in many instances, this is also the most expensive option, as it can require both travel and time away from work. 

Regardless of your learning style, the IFPS is here to support you every step of the way as you work toward your goal.

CRDV, CRDV/S, and CRDV/S with WiFi

By Patrick Byce, Marketing Coordinator, Spartan Scientific

»

SPARTAN SCIENTIFIC, an American manufacturing facility located in Northeast Ohio, specializes and builds fluid control products within the automation industry. Spartan has learned through their many years of experience that, not only the automation industry, but all industries are constantly evolving. New ideas accompanied by new innovations and technologies are regularly assimilating into different types of businesses and manufacturers as efficiency, productivity, performance, and cost savings continue to stay at the forefront of nearly every industry.

Air Compressors are used every day within an incredibly diverse range of industries—industries that are all striving to be more efficient, proficient, and economical. Today, we see that air compressors are core components of engineering, manufacturing, construction, agriculture, mechanical work, factory assembly lines, transportation, and many more. A common characteristic of all air compressors is the natural accumulation of water. In fact, water accumulation contributes to a majority of problems and maintenance issues within many industries. Those who have experience in engineering and construction are likely to be aware of this.

One of Spartan Scientific’s first products developed was the Series CRDV, also known as the “Condensation Removal Drain Valve.” When Spartan Scientific came into existence back in 1987, they were fully aware of this age-old problem and understood what kind of consequences would transpire if the natural buildup of water began to overtake an air compressor and its air lines by not being drained frequently or correctly. By addressing the problem of excess water, the Series CRDV Condensation Removal Drain Valve dramatically improves the life of air compressor systems, which leads to increased efficiency, productivity, and cost savings. The Series CRDV makes it so that the water accumulation can be drained and removed at any point WWW.IFPS.ORG • WWW.FLUIDPOWERJOURNAL.COM

THEN AND NOW

within an air system, using a solid-state timer and a proven solenoid valve operator.

As technology has evolved, Spartan Scientific continued to make positive changes to keep up with their customers’ changing requirements.

The Series CRDV has proven to be a great product, but there were ways to increase efficiency even more. The Series CRDV will drain water build-up after a set amount of time, which means that certain conditions, such as low humidity, would generate much less water than normal to high humidity. This would cause the Series CRDV to open up and purge the compressor regardless of the amount of water present in the air compressor. Purging more often than necessary causes air loss within the compressor

system. Over time, air loss will add up and lead to a loss of substantial amounts of money.

To combat this problem, Spartan Scientific developed the Series CRDV/S in 2008. This enhanced drain valve took the same underlying principle of draining water build up, but made it so that the process would not cause a compressor system to undergo unnecessary air loss. The key component within the Series CRDV/S is its self-learning mode that will open the valve to drain only when it senses the presence of water. Other features of the CRDV/S include a 24-hour self-cleaning cycle, status indicator lights for easy maintenance, and an environment-resistant design.

In 2019, Spartan Scientific will be releasing an enhanced and more evolved version of their Series CRDV/S. This version is a WiFi-enabled drain valve that uses IoT (Internet of Things) technology. When asking Spartan Scientific’s Chief Engineer Phil Muntean why IoT technology would be an important feature to potential consumers, he explained: “It’s the freedom.

There are no boundaries and you don’t have to be restricted to your facility to monitor any of your equipment. You can be at home sitting in your living room watching television and view real-time data that tracks any type of unusual behavior or inconsistencies that your systems might be experiencing. Imagine receiving an email or text message alert, sent directly to your phone, that notifies you that your system is acting erratic or that it may need your attention soon. The IoT CRDV/S drain valve will be able to prevent problems before ever happening.”

The idea of IoT technology might be new to some, but manufacturers, businesses, and organizations alike are using IoT technology in a diverse variety of industries to operate more efficiently with higher cost savings and to better understand their customers, which in turn will enhance customer service, improve decision-making, and increase the value of their business.  JANUARY 2019

Filler BREATHERS Filter

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

I

once worked at a blow-molding facility with 16 hydraulic power units. The units had been made back in the 1960s, purchased at auction, then returned to “like new” condition.

The “like new” condition was that of the original design which produced a lot of heat. The heat made the seals brittle, creating leaks and requiring a continuous effort to keep the reservoirs “topped off.”

Each reservoir had a filler port with a cap on it. In the interest of convenience, the maintenance team would often leave the fill port uncovered. Fluid was transferred from a 55-gallon drum to a 5-gallon pail. The technician would then bring the pail and a funnel to the reservoir and pour the fluid into the fill port.

Now, most of us know that the major cause of failure in our fluid power systems, both hydraulic and pneumatic, is contamination.

Back in 2008, there was an article in Fluid Power Journal titled “Let’s Keep It Clean.” It is hard to “Keep 8

filter to receive the transferred fluid.

In either case, no unfiltered fluid enters the reservoir.

However, many users of hydraulic equipment are untrained and unaware of the hazards of using unfiltered fluid. Small reservoirs are usually made with one fill port, so it is the only location for adding fluid.

Similar to the blow-molding facility, little attention is paid to pre-filIt Clean” when a major source of tering the fluid.

A The International Fluid Power well-designed hydraulic system Society encourages the industry will include assurance that only to recognize the need to properly properly filtered fluid is added to filter the fluid added to the reserthe reservoir. This may be by means voir.

This might seem like a

nitpicky nuance, but the difference in connotation is important. If an untrained maintenance person is given the instruction to fill the new reservoir, it would only seem reasonable to use the part called the Filler/ Breather as the location to add the fluid. Removing the cap would reveal a nice, shiny mesh screen and, without proper training, it would seem only logical that adding fluid here would prevent any bad stuff from getting into the reservoir.

When there is provision for properly adding fluid through the return filter, accurately referring to the device as a Filter/Breather may discourage someone from using the wrong location as the fill point. When this is the only opening to the reservoir, having a Filter/ Breather forces the question as to where and how the fluid is added.

To achieve certification as a fluid power professional, a candidate must properly identify and describe fluid power symbols. The Filter/Breather must be properly recognized and not described as a Filler/Breather.

Many excellent manufacturers still market their Filter/Breathers as Filler/Breathers because this is familiar to the industry, and it does define the location where the filter is to be installed. But for clarity and consistency, it would be best to describe them as Filter/Breathers. 

A CUSTOMER OF ours bought a machine that had a damaged cylinder that needed to be replaced. The rod was bent, and they ordered a replacement cylinder with a larger diameter rod thinking it would eliminate the original problem.

The machine was put into production and worked well with one exception.

Each time they stopped the cycle for more than 15 seconds, the cylinder started to drift out causing a potential safety problem. The cylinder supplier shipped them a replacement cylinder, Any idea what but the problem persisted. The circuit was confirmed to could be causing be correct and matched the machine hydraulic set-up. the problem?

olution to the Previous Problem: Large Punch Press Cylinder Stutters On Downward Extension

S

The stutter problem with the 600-ton cylinder on extension was caused by loss of pilot pressure needed to keep the pilot-operated directional valve shifted. The ram would fall fast enough to almost “run-a-way from the pump” supply flow. The spool would unshift allowing pressure to build up, then the spool would fully shift starting the spool cycle to repeat.

They added a counterbalance valve on the rod side with an external pilot and 4:1 pilot ratio and it solved the stutter problem. They also changed the directional valve spool to a blocked “P” and “B” with “A” port connected to the tank to hold the ram in the up position when stopped.

7 Habits

to Take Your Workplace Culture to New Heights

By Elizabeth McCormick

“Winning is a habit. Unfortunately, so is losing.” – Vince Lombardi

»

YOUR BELIEFS DICTATE your behavior and your behaviors create habits that determine your destination. You’re either going towards greatness or obscurity; there is no neutrality to your momentum. So where are your habits taking you?

Leading your organization towards a specific destination or goal is like being a pilot of a passenger airplane – wherever you go, your company goes. There isn’t an auto-pilot setting for you if you expect to take your team to greater heights.

If you find yourself and your organization stuck, or you’re ready to rev up your engine to soar higher, it may be time to engage your discipline and do the difficult things that other leaders may not do.

Here are seven habits that can help you take your organizational culture to new heights:

1. HOPEFUL EXPECTATIONS Whatever you look for is exactly what you will find. If you expect to find problems, you will. If you expect your team to discover creative solutions, exceed their potential, come together as a team and support you, your vision, and your company goals – they will. A positive mindset is the first habit you need to cultivate and grow a winning mindset. Without it, you will fail to see what’s possible.

10

JANUARY 2019

Action Plan: When faced with a new idea, prospect, or proposal (especially in a meeting with your team), always communicate the positives first. Encourage and engage your team members to participate in developing new ideas.

Cultivate innovation by asking them to spell out the pros and cons of their ideas. Then, when they’re ready, empower them to run with it.

2. ELIMINATE MULTITASKING Just because you’re busy, doesn’t mean you are productive. When too much emphasis is put on multitasking, it could lead to miscommunication, mistakes, frustration, and unmet goals. It’s not about how much you can multitask, it’s about knowing which task can multiply your results.

Action Plan: Remove all distractions, then decide which task needs your attention and work on it until it’s done. This works for meetings too. Put your devices away and give your full attention to your team. Before you know it, they will follow your lead.

3. INTENTIONAL KINDNESS Many people have experienced random acts of kindness, but it’s time to be more intentional in showing kindness to yourself and your team members. Become more aware of how you can encourage others, add value, meet the needs you see, and extend grace whenever needed. As you do, you’ll begin to see that spread throughout your organization and beyond.

Action Plan: Set up a charity of the month.

Assign a 12-person committee with each member taking ownership of one month.

Some ideas include collecting winter coats and canned food, walking as a team in a fun run or 5K fundraiser, hosting a blood drive, adopting a highway, or spending a day with Habitat for Humanity. Encourage involvement by participating full out.

4. GEAR DOWN In today’s world, it’s tough to find time to think, yet that’s one of the more critical elements of success. Studies show that intentional down-time improves productivity, energy, and results. Don’t fall for that top-speed mentality or you’ll eventually run out of fuel. Schedule some time to gear down.

Action Plan: Prioritize some non-negotiable time on your calendar just for you. Create a distraction-free space where you can clear your mind and unplug from everything. Start with just 10 minutes if that’s all you have, but just start. You’ll be amazed at the clarity and productivity you’ll experience as a result.

5. HIDDEN OPPORTUNITIES Being proactive is one of the hidden opportunities that leaders often miss. Instead of waiting to see what the day holds and reacting to that email, phone call, or situation, a more strategic approach is to determine responses before calamity strikes.

Action Plan: Along with your yearly planning meetings to fine-tune the company’s vision and goals, be strategic about anticipating potential problems. Have an “Anticipation Meeting” with the goal of creating contingency plans and ask each department to develop a “what if” list, WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

along with solutions. This type of strategy allows you and your team to be more creative in your problem-solving abilities while in a calmer state than an emergency allows.

6. TALK IT OUT Make it a habit to communicate openly with your team and allow them the opportunity to take part in the conversation. When communication is lost, your teamwork and productivity will suffer right along with your company’s goals.

Action Plan: No one likes to be kept in the dark. Be clear in meetings about expectations, goals, and their command structure.

You can also set a time where everyone knows your door is open to talk for topics that need to be dealt with one-on-one.

7. SHARE THE LOAD Establish a habit of sharing the load. Delegating important tasks is another way you can honor and empower your team to take on new responsibilities that help to sharpen and show off their strengths.

Action Plan: Encourage a company culture where employees at all levels have the chance to share their ideas, talk about what they do, and possibly mentor new up-and-comers in your organization. When leaders at all levels take ownership of the company vision and goals, there’s no limit to what you and your organization can do.

When you choose winning habits by believing in the potential of your team, looking for the best in others, extending kindness, and creating space for them to give back, share ideas, and lead, you provide the jet fuel to ignite their creativity as you empower them to discover new levels of success. Don’t be satisfied with the status quo – make winning a habit so you and your team can soar to new heights. 

A COST-EFFECTIVE ALTERNATIVE:

Adjustable End Position Stops

Multiple-Position Pneumatic Linear

SLIDES

Guided/Supported Saddle

By Carey Webster, Engineered Solutions Manager, CFPPS, PHD, Inc.

P

neumatic linear slides are used in a wide range of applications throughout many industries. Guided and supported linear motion is the foundation for many of these applications. Over the years, the requirement for flexibility and more productive devices has led to the need for multiple-position linear slides, but providing multiple positions with a pneumatic linear slide can be a tricky proposition.

There have been numerous products introduced using pneumatic servo technology with some success. The compressibility of air, potential contamination issues, and high cost have limited the success of these pneumatic servo systems.

Another more popular alternative is to use electrically driven linear slides using a belt or ball screw drive and servo or stepper motors.

14

JANUARY 2019

Shock Absorbers Built into the Saddle

Adjustable Retractable Pneumatic Stops

This technology has been widely adopted, but comes with a higher initial investment than a pneumatic linear slide. One cost-effective alternative is a pneumatic linear slide using adjustable built-in pneumatic stops to achieve very accurate multiple positions.

The idea of incorporating built-in adjustable stops on a pneumatic linear slide does not fit every application, but is effective where 3 to 5 adjustable positions are needed. The example presented in this article is a saddle or carriage-type pneumatic slide using a built-in rodless cylinder as the drive mechanism. The

load-carrying carriage is supported and guided by a built-in precision rail bearing assembly.

The adjustable stops attach to the slide and are locked in place via hardware that engage tee slots in the body of the linear slide. The stops are retractable and are pneumatically extended to stop the saddle whenever the position is required in the application. Retraction of the pneumatic stop allows the linear slide to move to the next required position. Multiple stops can be installed on the saddle slide depending on the number of positions required. Built-in hydraulic shock absorbers in the saddle are used

WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

to help decelerate the saddle at each mid-stop.

Adjustable end position blocks can be used to shorten the overall stroke if required.

Consideration must be taken for load and velocity used with this type of linear slide. It is advisable to review all application information provided by the manufacturer of any pneumatic linear slide. The attitude (horizontal or vertical) of the slide is an important factor of the application. When linear slides are used in a vertical attitude, the effect of gravity on the load must be considered. Many manufacturers have sizing software available to confirm that the linear slide will perform in each specific application.

One advantage of this type of multiple-position pneumatic linear slide is the positional accuracy provided. Because this uses a positive pneumatically powered mechanical stop, the accuracy and repeatability is much better than that of a slide using pneumatic servo technology.

Typically, the repeatability is 0.0016-inch of the original position.

Switches can be used to provide an input signal to various types of programmable controllers or logic systems to indicate the linear slide is in each position. These can be propriety switches designed to fit into the linear slide body or commercially available proximity switches.

Valving is an important consideration when applying a multi-position linear slide. This type of unit not only requires a directional control valve for the linear slide, but also requires a directional control valve for each intermediate stop. The type of valve used and the manner in which each valve is plumbed is critical to the function of the linear slide.

The multi-position linear slide needs to be controlled by center pressurized (pressure center) or equivalent-type valves. Failure to maintain pressure on both ports of the linear slide when releasing the stopped saddle assembly can cause it to rapidly accelerate upon release of the pneumatic stop. This rapid acceleration can cause physical injury to personnel and/or damage to equipment.

Most linear slides use back-pressure on the exhaust side of the slide piston to regulate saddle speed. Presence of adequate back-pressure is critical when the saddle, stopped by the pneumatic stop actuator, is released. If air opposite of the pressurized side of the slide piston is exhausted to ambient pressure before the saddle is released, the saddle

can rapidly accelerate to high velocity before enough back-pressure can build to regulate saddle speed. See pneumatic circuit diagrams in Figures 1A and 1B for the best method of plumbing a multi-position linear slide.

The concept of using a pneumatic linear slide with pneumatic stop actuators provides a simple alternative to electrically driven slides or pneumatic servo slides. The use of hydraulic shock absorbers in the saddle provides deceleration capabilities at each position.

The greatest limitation is the practical number of positions. This concept works extremely well, but there is the ‘law of diminishing returns’ as a user adds more and more mid-positions. The application makes sense with 3 to 5 total positions. More positions may be added depending on the total travel of the linear slide. The designer must consider the additional complexity regarding the number of directional control valves required and the costs associated with those valves and plumbing for each position.

A pneumatic multi-position linear slide using pneumatic stops is a great solution and provides the designer with cost-effective alternatives to traditional types of linear slides. 

COMPRESSED AIR SYSTEMS

Compressed Air Maintenance:

Stop, Look, and Listen

By Ron Marshall

»

STOP. LOOK. LISTEN. These are important words of advice if you want to keep your compressed air system running in a trouble-free manner, and at the lowest possible cost.

The key to a successfully running system is careful observation of various important parameters and conditions in the compressor room and in the facility. So often the attention paid to an air compressor or system is during a reaction to a problem, but the trouble-free operation of an air system requires proactive maintenance and constant repair.

This leak was found during a quiet down time while it was consuming 25% of the compressor capacity.

Let’s discuss these points: STOP – Shutting off your compressed air system during nights and weekends, or during non-productive periods saves energy. Turning off your air compressors allows a quiet time where you can observe some potential trouble for your compressor and your pocketbook. It is good to observe how fast the system pressure drops when the compressor is turned off. An immediate drop of 5 psi or more signals a high pressure drop in dryers, filters, and piping. You may need to do something to reduce compressor operating costs. A very slow pressure drop a few seconds after the compressor turns off shows your level of leaks and the relative size of your storage receivers. If your system pressure crashes more than 20 psi in a minute, with no production machines running, you may have high leakage or a lack of proper system storage.

LOOK – This is a pretty tall order, but look in the compressor operating manual and find the maintenance requirements. Observe the compressor hour meters and see if you have been changing lubricant and filters in a timely manner. In air compressors, the lubricant receives harsh treatment, worse than typical machinery. Changing lubricant regularly is very important, or you risk future mechanical problems. Check all filter indicators and pressure gauges to ensure no high pressure differentials exist. Observe condensate drains—the drains in the compressor, receivers, air dryer, and filters. These need to be working to ensure high quality air enters the 26

Ron Marshall is owner of Marshall Compressed Air Consulting, a company that specializes in compressed air efficiency assessments.Visit www.compressedairaudit.com Join the LinkedIn discussion group: Compressed Air Efficiency plant. Also, check the general compressor room area. Clean any high levels of debris that may restrict ventilation or get caught in compressor ventilation passages. Ensure primary filtration, if included in the room ventilation system, is clean and free of restrictions.

LISTEN – A big driver of compressed air costs is system leakage. Starting in the compressor room, listen for leakage just after the compressor has been turned off. Are big leaks robbing you of your compressor capacity?

Then, with the compressor back on, walk through the plant during quiet times of non-production listening for leakage, making sure to note leakage points for later repair.

Often 30% or more of compressed air costs will be caused by leakage. Best bet is to purchase an ultrasonic leak detector and use it regularly to keep your leakage levels under 10% of your compressor capacity or lower.

Properly following this advice will help keep your compressed air system running in a reliable and cost effective manner.  WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

Meet a Fluid Power Scholarship Winner - Allison Potts

»

THE NFPA EDUCATION and Technology Foundation recently awarded $2,000 scholarships to students pursuing fluid power technology fields of study. Here’s one of the winners, Allison Potts.

She is continuing her studies at the College of Central Florida, pursuing an A.S. degree in Advanced Manufacturing Specialization. We asked Allison about winning the scholarship.

WHY DID YOU CHOOSE TO LEARN ABOUT FLUID POWER? I was exposed to this field at an early age. Growing up, I had a vision of how things worked. I didn’t realize it until later I would be fascinated with fluid power.

Watching the pressure gauge to give me an idea of how much power is being pushed through to make something move is amazing. The physics in this is mind-blowing.

WHAT ARE YOUR CAREER ASPIRATIONS? I want to be able to explore my knowledge by owning my own controls business. When my father retires, I plan to take over his business and continue working with controls. There are machines I will be working with that use fluid power and I look forward to it.

WHAT TYPE OF FLUID POWER JOB DO YOU HOPE TO GET AFTER YOU GRADUATE? I hope to work with machines that have fluid power in them. My goal is to help customers improve the quality of their machines for better production.

KaeLeigh Grace Photography

WHAT DOES WINNING THIS FLUID POWER SCHOLARSHIP MEAN TO YOU? Winning the scholarship means I am doing something right with my future. I had no idea I would choose this career because I wanted to be a zoologist when I first graduated from high school. Now I know what kind of career I will be following. I enjoy working with a team of intelligent people, and I hope to expand our knowledge and use it to make a new invention of some kind.

The 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 on the scholarships, contact Carrie Tatman Schwartz, Workforce Development Manager at ctschwartz@nfpa.com.

Energy Efficient Fluid Power Discussed at Off-Road Vehicles Research Workshop

By Eric Lanke, NFPA President/CEO

»

I RECENTLY ATTENDED a workshop at the Argonne National Laboratory to discuss strategies for increasing the energy efficiency of off-road vehicles. The workshop was hosted by the U.S. Department of Energy (DOE) as part of its new $10 million research funding program dedicated to the same cause. I was joined there by more than 80 representatives of fluid power components manufacturers, fluid suppliers, OEMs, research universities, and other national labs. It was an impressive gathering!

The goals of the workshop were clearly laid out: • Identify

the barriers to cost-effective, highefficiency off-road vehicles. pre-competitive research topics that • Identify

The practical use of real-time feedback on component or fluid performance to drive more efficient system control was near the top of this list, with the acknowledgement that more inexpensive and reliable sensors would be needed to make such an objective possible. and use advanced fluids that can • Develop

increase energy efficiency. As hydraulic fluid becomes more and more technically advanced, the co-development of those fluids with the components that they will work with was seen as critical. Examinations of wear on traditional components could provide insights into the smart materials or coatings necessary to produce components better aligned with new low viscosity grade and high viscosity index fluids. energy density of fluid power • Increase

energy storage to facilitate cost-effective hybridization. Hydraulic accumulators beat electric batteries when it comes to power density, but not when it comes to energy density. To better close this gap, explorations into non-traditional energy storage technologies were recommended, as well as reductions in the size and weight of traditional accumulators.

Finally, there was a long discussion on the need for an objective way to measure the impact of any or all of these ideas on system efficiency. Knowing that the off-road vehicle market contains hundreds of vehicles with thousands of different duty cycles, the development of a standardized duty cycle

was dismissed in favor of a few elementary metrics for systems, components and fluids that incorporate both steady state and dynamic conditions. For example, standardized metrics could be developed for torque and speed from rotary output in steady state, ramp up, and ramp down conditions. It was believed that such a set of metrics could allow the comparison of different architectures and components without linking it to a specific mission profile.

What the DOE decides to do with this input remains to be seen, but we are expecting a full report from the workshop by the end of the year, and, probably a broad agency announcement for new funded projects shortly thereafter.

All of this matters because it is through federal programs like this that the academic careers of fluid power faculty and graduate students can best be supported.

These are the people who are and who will be teaching fluid power to the next several generations of undergraduate engineering students – students that our industry seeks to hire and whose fluid power skills will make or break the next several generations of fluid power products. NFPA played a role, but it was the Center for Compact and Efficient Fluid Power (CCEFP) that did the hard work necessary to get such a program launched within the DOE. The least we can do now is stay engaged and to help ensure that the available funding goes to industry-relevant projects.

LINEAR DISPLACEMENT TRANSDUCERS STRONG, TOUGH AND RELIABLE

Take on the Most-Demanding Applications

By Blake Cawley, Product Manager, AMETEK Factory Automation

The importance of automation is greater than ever, as is the role played in automation by linear displacement transducers (LDTs). Today’s industrial challenges often involve pounding, continuous vibration, high pressure, extreme temperatures, and relentless cycling. LDTs have proven to provide accurate, reliable, absolute position feedback under extreme conditions in the most-demanding industrial environments, while, at same time, delivering value, easy set-up, and flexibility.

A

range of automation solutions can provide accurate, continuous position feedback, but LDTs incorporating advanced magnetostrictive technology can provide precise, accurate, and absolute non-contact position feedback down to one-micron resolution. The technology itself is not new, nor is it rocket science. However, most importantly for many industrial applications, it is extremely rugged.

LDT sensors can be packaged to survive the most hostile industrial environments, while performing reliable, repeatable, and accurate linear measurements.

Magnetostrictive technology relies on the same physical principles that allow motors and generators to operate. This is basically how it works. In the head of the LDT is circuitry that generates a pulse of current that is sent down a special ferromagnetic (magnetostrictive) wire inside the sensor’s 32

protective tube or extrusion. Outside the tube is a movable magnetic target. When the pulse interacts with the magnetic field, it generates a torsional twist that travels along the length of the wire at a fixed rate of speed that can be precisely measured.

The position of the magnet can be determined by measuring the time between the launch of the current pulse and the arrival of the torsion strain pulse. No direct contact is involved, and, along with that, absolutely no wear on the sensing element.

While many linear automation solutions provide accurate continuous linear position feedback, the

most traditional approach uses an analog signal feedback to an analog input module or drive.

Analog signals are limited by the resolution of the sensor and the input module. In addition, signals are prone to degrade over long cable runs, and each axis needs its own dedicated cable.

LDT users have overcome those shortcomings with Synchronous Serial Interface (SSI) sensors. SSI LDTs can provide serial-clocked output of binary or Gray code positional data with one-micron resolution regardless of stroke length of the sensor or the length of the cable run. The displacement value, or position, is encoded into

24-, 25- or 26-bit formats and transmitted at high speeds.

Synchronization in a closedloop system is relatively easy. A clock-pulse train from a controller is used to shift out sensor data. One bit of position data is transmitted to the controller for each clock pulse received by the sensor. Absolute position data is updated continually by the sensor and converted by the shift register into serial information. SSI LDTs can interface seamlessly with virtually any programmable controller that can communicate with an SSI device.

One disadvantage is the modules typically can’t handle more than two axis per module, and each axis requires its own cable.

Among the most recent technical developments are networked LDTs that provide non-contact feedback and one-micron resolution, while offering maximum installation flexibility and ease of use in highly demanding networked industrial applications. These include pulp

and paper, steel mills; lumber and forest products equipment; primary and secondary metals processing, such as stamping, roll forming and die-casting; tire and rubber, plastic injection-molding; and material handling machinery.

LDTs typically find application in a broad range of industries that require a machine or a piece of equipment to move in a linear fashion and feedback to automate it.

LDTs are available in two package styles: the traditional Rod Style package suitable for installation into hydraulic cylinders and the Profile Style that incorporates similar electronics, but houses those electronics in an aluminium extrusion for ease of mounting.

Some Rod Style transducers are rated for up to 30 Gs of vibration and 1,000 Gs of shock, and are available in a wide range of outputs, allowing them to interface with a variety of host controllers.

The choice of style depends on what works best for an application.

Rod Style transducers, for example, are preferred for hydraulic cylinders because of the LDT’s ability to withstand operating pressures up to 5,000 PSI that at times can spike to 10,000 PSI. For an LDT to operate properly

These linear transducers use magnetostrictive time-based position sensing in which a pulse is sent down a magnetostrictive wire in a specially designed waveguide.

The interaction of this current pulse with the magnetic field created by a movable magnet assembly produces a torsional strain pulse on the wire. Which travels at sonic speed along the wire.

in a hydraulic cylinder, it must be prepped to accept a Rod Style transducer. The cylinder piston must be gun drilled with a 12.7mm (half-inch) bore and the end cap machined to accept a linear transducer. A magnet also must be added to the cylinder’s piston.

On Clevis style cylinders, there is typically no room to mount a traditional Rod Style transducer.

In this instance, there is an embedded-style transducer package that totally encapsulates the LDT inside the cylinder, protecting it from outside conditions and making it resistant to contaminants and other hazards. This compact housing LDT is the ideal for agricultural,

construction, and mining equipment and commercial vehicles.

LDTs also have become smarter.

Many models are now field configurable for output type, zero position, counting direction, position and velocity format, and resolution.

Some, more-sophisticated sensors can even support wide ranging power supplies (7VDC to 30VDC), so the same unit can be used in both stationary and in mobile applications. These wide-ranging power supply capabilities allow newer linear transducers to be backward compatible with older generations that need a +/-15V bipolar supply. Diagnostic LEDs also have been added to aid with

The movable magnet’s position is determined with precision by measuring the time between launching the current pulse and the arrival of the torsional strain pulse.

troubleshooting, and standardized cables, such as 12mm Euro-style cord sets, are available as an option, helping to reduce installation costs.

Automatic gain, or AGC, was introduced years ago to help compensate for different style magnets found in hydraulic cylinders. On power up, most sensors are now able measure the strength of the magnet and automatically adjust its internal signal lengths to match the user’s installed magnet. This is a benefit in hydraulic cylinder applications in which the brand of installed magnet is a different from that of the sensor.

Linear displacement transducers have proven their value over the years by delivering reliable position measurement for a broad range of applications. Furthering their application in industrial automation has been the ability of LDT makers to design and build sensors that meet and exceed customer expectations in the harshest and most-demanding circumstances.  JANUARY 2019

the world of high-speed factory automation, speed is everything.

Manufacturing processes require fast cycle rates to increase output and overall production efficiency.

This article discusses strategies to implement in vacuum pick and place applications to minimize production cycle times. There are many contributing factors with some more effective than others. However, as we all know, every fraction of a second counts.

In

VACUUM PICK AND PLACE

HIGH-SPEED CYCLE TIME REDUCTION

By Dane Spivak, and illustrations by Daniel Pascoe, Davasol Inc.

Figure 1: Vacuum cup compression distance

VACUUM CUP SELECTION The most important part of vacuum cup selection is determining a model that offers an adequate seal to safely lift the product. If this is achieved, the following cup characteristics are to be considered in cycle time reduction – cup style, material, and internal volume.

The style of a cup will determine how long it takes for the product being gripped to meet with the datum point inside of the cup. Or in other words, the time it takes for the cup to compress under vacuum.

Figure 1 compares a flat-ribbed cup to a multiple bellows cup. As indicated by the arrows, the distance the cups must compress before meeting its datum point (the internal base of the cup) is drastically different. The lesser this distance, the less time it takes for the cup to compress.

The reverse effect of compression can also disturb cycle rates. Commonly referred to as material memory, the cup deforms under vacuum, and when vacuum is released and the product is dropped, there is a time consideration while the cup returns to its original state of rest.

34

JANUARY 2019

Figure 2 shows two cups with the same compression distance.

The foam cup on the right has poor material memory compared to the rubber cup on the left. This means the foam cup needs more time to return to its original state to start the cycle.

The internal volume of a vacuum cup determines how much air needs to be evacuated to achieve the desired vacuum level. Since the lip diameter of the cup is directly related to the lifting force, the first step is to size the diameter of the cup correctly to lift the parts securely.

Ideally the smallest diameter of cup should be chosen to reduce the inner cup volume. Next, we look at the inside of the vacuum cup and how much volume of air it contains. Again, ideally, we would like to reduce this volume as much as possible. Reverting back to Figure 1, the flat cup on the left is preferred to the bellows cup on the right.

Conveniently enough this aligns with the compression aspect of the vacuum cup previously discussed.

So what can we conclude from the aforementioned? When selecting a vacuum cup for a high-speed

Figure 2: Vacuum cup material memory

Figure 3: Typical cup, vacuum valve, and pump circuit

application, it is best to use a small, flat, low-volume cup with good memory.

VACUUM VALVE LOCATION In a typical vacuum pick and place application, the vacuum valve is located somewhere between the cup and pump to turn vacuum on or off as demonstrated in Figure 3.

The valve location is critical to the pick and drop speed of the product.

Assuming the pump is running constantly, the vacuum line between the pump and the valve acts as a vacuum reservoir and “recharges” the vacuum line when the valve is closed. This volume, which we will refer to as V1, is important as we will see in the following analysis. When the valve opens to allow vacuum to be applied to the cup, the air from the valve to the cup lip is the volume of

WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

air to be evacuated. This is the other important volume, which we will re refer to as V2. The sum of volumes V1 and V2 will be referred to as VT. To decrease cycle rates, the goal is to have a high ratio of V1/V2. A larger volume of V1 will allow for a more efficient vacuum reservoir to evacuate V2. A smaller volume of V2 results in less air to be evacuated with the assistance of V1. Not only that, the V2 volume is related to the drop speed as well. The smaller the volume in V2 means less air to reintroduce and consequently less time to release the part. To further increase the release (exhaust) speed, a pulse of compressed air can be applied during the exhaust cycle.

Back to the V1/V2 ratio, let’s apply the ideal gas law to this concept and see how it affects the vacuum level.

As shown in the above calculations, we see that when the V1/V2 ratio increases the initial vacuum level of the system is higher when the valve opens. This means that the overall vacuum level is higher and the pump needs to remove less air to achieve its highest desired vacuum level. The result is a quicker reaction of the cup and reduced time to meet faster cycle rates.

Vacuum flow, typically measured in cubic feet per minute (CFM) in North America, is the volumetric rate at which air is removed from a system. Flow is different from vacuum level. Vacuum level is the result of removing air from a system, which creates a pressure lower than atmospheric. Usually relatively high vacuum levels are easy to achieve, but getting to that vacuum level as quickly as possible is dependent

when the pump initially starts to run. However, the ACFM ratings, actual cubic feet per minute, is often more important to the overall performance of the pump.

The ACFM ratings are flowrates at different vacuum levels (lower atmospheric pressure).

Figure 4 compares a regenerative blower curve to that of a venturi. Both units have Both units have comparable SCFM

pT x VT = p1 x V1 where p is pressure (vacuum level) and V is volume p1 x V1 p1 x V1 pT = _______ = _______ V1 + V2 VT where pT is the vacuum level when the valve is open to the cup

Let’s consider two scenarios with different volumes while the pressure is constant. We won’t use units for simplicity. Arbitrary numbers have been chosen below.

p1 = 10; V1 = 5; When V2 = 5,

V1 =1 V2

10 x 5 =5 5+5 V1 =5 When V2 = 1, V2 10 x 5 pT = = 8.3 5+1 pT =

Figure 4: Regenerative blower and venturi vacuum flow versus vacuum level

Another quick note about vacuum valves. The cycle speed of the valve itself and flow capabilities will provide different results.

Quicker cycled valves and flows which match the pump performance are critical. Flow will be discussed in further detail in the coming sections.

CHOOSING YOUR PUMP It’s well known that vacuum generation units are key to the performance in any system, and it is no different in high-speed applications. Popular pick and place pumps include vane pumps, regenerative blowers, and air powered venturi generators. There are many more options but, in all cases, related to cycle time, the area of focus is vacuum flow.

WWW.IFPS.ORG • WWW.FLUIDPOWERJOURNAL.COM

on the flow. Higher flow pumps will achieve the final vacuum level sooner and decrease the cycle time.

All vacuum pumps have published flow ratings though these listed numbers can be interpreted differently. Specific types of pumps will result in different flow performances, even if they have the same listed value in literature. Let’s continue using the CFM units previously defined. Most flow ratings listed in data sheets or catalogs are associated with the pumps SCFM rating. This is the standard cubic feet per minute measurement, which is correlated to the pumps flow performance at standard temperature and pressure. In our case, this is an ambient temperature of 68°F (20°C) at an atmospheric pressure of 14.7psia (0.1 MPa)

ratings of 80SCFM though the curves demonstrate that ACFM values create a substantial gap. If we consider the values at 12”Hg, we can see that the blower offers around 50ACFM, while the venture only provides 10ACFM. The blower is pulling an additional 40CFM. We conclude that the blower provides shorter evacuation times to reach vacuum levels between zero and 18”Hg. What we learned from this analysis is that the listed ratings of pumps provide limited information. The flow vs vacuum level curve should be understood to truly maximize cycle speed.

Although they may not be the ideal type of vacuum generator for high-speed applications, venturis are often implemented in pick and place. Venturis consume JANUARY 2019

35

compressed air to generate vacuum and are used for their low cost, low weight, and application simplicity.

As shown in Figure 5, a vacuum cup is often close-coupled to the venturi for point-of-use generation. Single-stage venturis offer quicker pick speeds than multistaged units. This occurs because multi-staged units have multiple stages that the compressed air must travel through as the name suggests. Single-staged units have one stage, and therefore, react faster.

Venturi reaction speed also relies on the pneumatic plumbing arrangement. A smaller volume of compressed air that must travel to reach the venturi will take less time to initiate vacuum generation. As with the vacuum valve, the pressure valve should be mounted as close as practical to the venturi.

Vacuum cylinders are quick reacting. The cylinder has a maximum stroke, but if the cup seals against the product anywhere through the piston stroke, it will instantly retract, resulting in cylinder cycle times of fractions of a second.

SIZING PARTS We’ve touched on vacuum flow and CFM ratings in this article and its importance to pick up speed. This concept is applied throughout the vacuum system

VACUUM CYLINDERS The vacuum cylinder is a product that is generally not well known though it can offer many benefits, particularly in high-speed applications. Vacuum cylinders are used to provide vertical positional movement of vacuum cups often referred to as the z-axis travel.

They can often replace pneumatic and electric cylinders and use the existing vacuum source from the cup to power the cylinder. Figure 6 breaks down the function of the vacuum cylinder step by step. <1> The vacuum cylinder is at rest with the piston rod retracted in the up position <2> When vacuum is applied, the piston moves downwards (extends) until the vacuum cup, which is attached to the piston via the connection thread, seals against the load to be lifted <3> Both sides of the cylinder are now equalized, and the internal spring retracts the cylinder rod to its original position holding the part securely <4> When vacuum is turned off the part is released from the vacuum suction cup

with every component from the pump vacuum port right down to the vacuum cup. All other interconnecting components, fittings, and hose should be sized accordingly to the pumps performance.

Figure 7 shows a table of vacuum flow through orifices of different sizes. Each component of the vacuum system should be sized so the appropriate amount of flow can be handled. If one portion of the system restricts the flow, it affects everything downstream from that point. One weak link can cause

significant effects. Tubing or hoses should be chosen so that their flow rating is equal to or greater than the flow rating of the pump. Note that when vacuum lines or components are in parallel, the flow capacity can be added together.

Other factors potentially decreasing flow performance are having unnecessary long lines or sharp turns in fittings and hose. Straight through flowing parts and smooth flowing vacuum lines are always a benefit. Lengthy hose can result in frictional flow losses and vacuum level drops.

CONCLUSION In this article, we’ve covered a few strategies to reduce cycle times in vacuum pick and place applications including cup selection, vacuum valve location, pump choice, vacuum cylinders, and sizing components. These strategies are a technical guide to assist in understanding fundamental principles. Each application is unique and should be studied independently to find which solution is the best fit. 
