Hybrid Learning By Donna Pollander, ACA, CEO, International Fluid Power Society

THE IFPS HAS recently unveiled an innovative hybrid training initiative, and I’d like to share both its success and program specifics. This training is designed to equip professionals with the knowledge and skills required to obtain an IFPS certification. We’ve re-engineered traditional technical training by incorporating a blended learning approach, combining 42 hours of online instructor-led sessions with hands-on labs facilitated by instructors. The labs utilize a specially designed custom training kit to enhance the learning experience. The pilot program was launched through a collaborative effort with three fluid power distributors in Ohio: S.G. Morris Co., a subsidiary of Applied Industrial Technologies, Kraft Fluid Systems, and The Paquin Company. In a collective effort, they put all competition aside and joined forces to equip and empower 11 candidates with the essential tools to obtain the Connector and Conductor Certification. IFPS facilitated weekly online training sessions and collaborated with designated personnel onsite to facilitate practical laboratory sessions within their respective companies. IFPS now independently delivers this training to individuals and companies aiming to offer their employees a thorough review of the essential knowledge and skills needed to pass a designated certification exam. One of the key benefits of the new program is its flexibility. Companies can offer both the online and in-person training at a time of day that is convenient to them and either appoint specific individuals within their company who have the best experience to provide in-person labs/ training sessions or opt to have Accredited Instructor supported, virtual hands-on labs, allowing participants to reinforce what they’ve learned in a practical scenario. Other highlights include:

Comprehensive 42-Hour Training: The program offers an in-depth curriculum that covers essential aspects of fluid power mechanics, ensuring a strong foundation of skills and understanding. • Tailored Training Kit: IFPS has meticulously developed a specialized training kit tailored exclusively for this program. The kit will be shipped to you and includes state-of-the-art tools and equipment carefully selected to facilitate hands-on learning and practical skill mastery. • Virtual Instructor-Led Sessions: Participants will engage in 12 virtual sessions, each spanning 3.5 hours, conducted twice weekly. These interactive online sessions will be led by an IFPS Accredited Instructor who will provide guidance, address questions, and offer valuable insights to enhance the learning experience. • Hands-On Learning Labs: Part of the virtual sessions include Accredited Instructor supported hands-on labs, allowing participants to reinforce what they’ve learned in a practical scenario. These labs enable hydraulic mechanics to refine their skills, build confidence, and develop proficiency. • Session Recordings: All sessions are recorded for convenient review and reinforcement for the duration of the program and two weeks beyond. Participants have praised the program for its comprehensive content, flexible delivery, and the high level of support provided by the IFPS. In fact, the pilot program was so successful the same group of 11 candidates is currently engaged in a follow-up program, working towards obtaining their Hydraulic Mechanic Certification. The IFPS's new hybrid certification review training program is an excellent option for individuals and companies looking to improve their employee’s knowledge and skills, increase safety, enhance productivity, improve work quality, provide a competitive advantage, and potentially reduce costs. The program provides a flexible and convenient way to learn while still providing the practical, hands-on training essential for success in this field. For more information on the program visit https://www.ifps.org/news. With this program’s success and other training programs in the works, the IFPS continues to demonstrate its commitment to advancing the fluid power industry and the professionals who work in it! •

Overheating Problem on a Sand Core Production Machine By Robert Sheaf, CFPAI/AJPP, CFPE, CFPS, CFPECS, CFPMT, CFPMIP, CFPMMH, CFPMIH, CFPMM, CFC Industrial Training

Back in 2016, I wrote up a problem on a machine that made sand cores. See the original circuit attached. Everything seemed to be the same other than they had omitted the other circuits that ran a couple small cylinders that were not used any more. Lately, they started having overheating problems that needed to be corrected. The unit was located on a 300-gal reservoir, and they did not

have this problem with overheating until they removed the 2-small cylinders that were plumbed after the check located near the accumulator. Maintenance felt that the problem was with the main pump relief and solenoid valve #1 so they replaced both valves. This did not fix the problem. Unfortunately, they were not familiar with the Core Squeeze circuit thinking it could be the problem and asked for help. For the solution, see page 23.

However, the safety engineers wanted to increase the margin of safety and asked to increase the emergency volume by 50%, but there was no room in the building that housed the hydraulic system for more accumulators. My friend was tasked with finding a solution. Here is an equation you might want to add to your toolbox. p1 p1 %V = 100• p2 p3

(( )-( ))

%V is the percentage of an isothermic accumulator volume that will be available when the pressure relationships are known, regardless of the size of the accumulator. p1 is the precharge pressure, p2 is the minimum pressure requirement, and p3 is the maximum pressure of the accumulator.

My friend discovered that, by increasing the maximum pressure of the accumulator, he would increase the available volume. He changed the accumulators from those rated to 21 MPa (3045 psig) to ones that are rated to 35 MPa (5075 psig). The existing pumps and electric motors were able to handle the increase in pressure and so there were very few changes needed to the hydraulic circuit.

WWW.IFPS.ORG • WWW.FLUIDPOWERJOURNAL.COM

By increasing the accumulator pressure to 35 MPa (5075 psig) he was able to increase the available volume by more than the 50% required (from 34% to 52%) without needing to put an addition on the building. It was deemed a great success.

But was this the best thing for the customer? Think about this for a moment. Even though we do not have all the details, we can still do some analysis based on the %V in the chart. A new ride begins every 10 minutes. The ride lasts about 6 minutes using 300 lpm (79.25 gpm). It then stops and people get off. Once they are all off, the new customers get on with the exchange taking 4 minutes. Then the ride starts again. In the event of a loss of power, the ride must safely come to rest, requiring 17% of the accumulator volume which is 136 liters (35.9 gallons). The average flow rate is 300 liters x 6 minutes / 10 minutes = 180 lpm (47.6 gpm). As all the cylinders return to the safe position, the accumulator pressure must not drop below the minimum pressure of 12 MPa (1740 psig). Using the equation:

Equation

Q•p K

Metric

P = Power in kW Q = Flow rate in lpm p = pressure in MPa K = 60

US Customary

P = Power in hp Q = Flow rate in gpm p = pressure in psig K = 1714

The average power required for the ride is 180 lpm x 12 MPa / 60 = 36 kW (47.6 gpm x 1750 psig / 1714 = 48.6 hp) The original system maintained at least 123 liters (32.5 gallons) of stored energy to return the whole system to a “rest” position. If the maximum amount of stored volume is 34% of the accumulator volume, then there would never be less than 18.7% remaining for emergency use. ACCUMULATOR SIZING (ISOTHERMIC) METRIC Solve For

Looking at the chart, we see that the lowest “demand charge” from the power company. The pressure in the accumulator during normal coolers will require more energy to remove the operation would be 15.69 MPa (2275 psig). The heat from the system. The heat generated in the average pressure would be midway between hydraulic fluid due to the high pressure drop the highest and lowest pressures of the working between the accumulators and the system accumulator.

This means that 123 liters must be Solve For Available Volume available at a minimum of 12 MPa or 1,476 l/ MPa units of energy (UE). The engineers wanted Base Unit 1 to increase the requirement to 2,214 UE. Precharge Pressure 9.6 Whoa, whoa! Wait a second! What is all this (Gauge) about “units of energy (UE)?” Minimum Pressure Bear with me for a moment.

Maximum Pressure Power is produced as the energy is released 2,587 (Gauge) at a rate of speed. For our purposes, we only % Volume 26% need to consider the stored energy as it relates Atmos MPa 14.69 to the work being done. If there are 100 liters stored at 21 MPa (26.42 gallons at 3,045 psi) there will be the potential The average pressure will be (16.9 MPa + 35 energy of 2,100 l/MPa (80,449 in.lb). 10 liters at MPa) x 0.5 = 25.95 MPa (3763 psig).

Now, back to the problem. In the original 36 kW / 77.9 kW = 0.46 or 46%.

actual amount of energy needed was 246 liters at 12 MPa (65 gallons at 1740 psi) or 2,952 l/MPa (113,100 g/psi), an excess of 51%.

What if it were possible to take all this extra energy and convert it into useful work? It is possible and is very simple. Enter the Fixed Displacement Power Controller (FDPC). (You probably know it as a rotary flow divider.) Now hang on, this is going to get weird. We will use the FDPC as a flow augmenter/pressure reducer. It will have two inlet ports and a combined outlet port that will lead to the amusement ride. The inlet to one section will be connected to the accumulators and have a displacement that is twice that of the other section. The smaller section will be ported to the reservoir. The net result is that whatever flow is being directed to the amusement ride, 66.7% will be taken from the accumulator and 33% will be drawn from the reservoir. The pressure leaving the FDPC will be 66.7% of the accumulator pressure.

The net result is that the available volume will effectively increase by 50%. 274 liters from the accumulators and 137 liters for a total of 411 liters with an output pressure of 14 MPa. Check it out. 274 liters + 137 liters = 411 liters. 274 liters x 21 MPa = 5,754 l/MPa. 411 liters x 14 Pa = 5,754 /MPa. The amount of energy units is exactly the same. When all the cylinders are fully extended, 123 of the 411 liters are used but only 82 liters are drawn from the accumulator, leaving 192 liters available for emergency use.

The accumulator pressure drops to 17.17 MPa (2,490 psi). The UE available are now 3,297 l/ MPa (126,990 g/psi). 123 liters x 12 MPa or 1,476 metric UE (56,538 US UE) are needed for emergency use. An additional 82 liters (21.7 gallons) will be taken from the accumulator leaving 110 liters at 14.5 MPa (29 gallons 2,102 psi), more than enough to bring the ride to safety. By thinking in terms of Units of Energy (UE) and rethinking the use of the common Fixed Displacement Power Controller (FDPC), the amusement park could have gained the extra fluid available and saved on their energy bill. The heat load would have dramatically less, reducing damage to the fluid, seals, and hoses. •

UNDERSTANDING BASIC TYPES & APPLICATIONS OF ACTUATORS

November 2023

WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

LINEAR ACTUATORS

ylinders may be single acting or double acting. Single acting cylinders exert a force due to air pressure only in one direction. Springs or gravity provide force in the opposite direction. Single acting cylinders have some advantages over double acting cylinders. Spring-retracted and spring-extended air cylinders require pressure to only one end. Therefore, the piston requires only a unidirectional seal. If the cylinder is a spring-retracted type of cylinder, the rod bearing may not include a seal. Since the directional control valve is required only to pressurize and vent the same port, a three port rather than a five port directional valve may be used. The air in the opposite end of the single acting cylinder is vented with a breather. Single acting cylinders have only one port to control speed in both directions. Without meterout capability on the spring side, the single acting cylinder cannot resist overrunning loads. Double acting cylinders have pressure applied alternately to each side of the piston and therefore have a bidirectional piston seal, such as a double cup seal, a double lip seal, or an o-ring, which seals in both directions. A typical double acting cylinder has a single rod protruding through the rod end of the cylinder. Double rod cylinders have rods that protrude from each end. Double rods would allow the cylinder to move loads in either direction with the same force for a given pressure, pushing or pulling. Double acting cylinders also come as tandem units, meaning they have more than one piston.

If the pistons are hooked together on the same rod but in two pumping chambers, they work in tandem to exert greater force. If the two pistons are not on the same rod, the rods can work in opposite directions, for example, to provide four positions with various combinations of extension and retraction strokes. These Fig. 1-4 Single Acting Cylinder are shown in Figures 1-6 and 1-7. One major advantage of double acting cylinders is the meter-out capability to stiffen cylinder movement and resist overrunning loads. Double acting cylinders also offer more possibilities in system design, because they can be used as single or tandem units. Rodless actuators are sized based upon the characteristics of the load they are carrying, operating speed, and actuator orientation. The center of gravity of the load, in relation to the center of the sliding block they are connected to, will impart both static and dynamic load moments Fig. 1-5 Double Acting Cylinder to the bearings used in the actuator. A static load moment is the force exerted at a distance on the bearings when there is no motion. Dynamic load moments are imparted during motion events and are strongest at acceleration and deceleration. These load moments will be on the X, Y, and Z axes and are designated as pitch, roll, and yaw. The collection of the correct data to properly size a rodless cylinder is necessary to ensure the static and dynamic forces on the bearings in the actuator are not exceeded. Data would include the operating pressure, stroke time, mass of the load, geometry of the load, dimensional relation of the load to the center of the rodless actuator’s sliding block, and actuator orientation.

ROTARY ACTUATORS

(MOTORS AND LIMITED ROTATION)

Air motors and limited rotation actuators use compressed air to generate torque and provide rotary motion. An air motor can operate in both directions continuously while a limited rotation actuator typically rotates only 359° or less with the limit typically being 270°. Limited rotation actuators are described in Outcome 3.17 and sizing air motors is explained in Outcome 3.11. There are several reasons why air motors may be selected over an electric motor for a given application. Some of these reasons are:

Fig 1-7 Three and Four Position Cylinders

Air motors generally produce less heat than an electric motor.

They can be operated in a volatile environment.

The speed of air motors can be easily controlled with simple flow controls.

Some disadvantages of air motors when compared to electric motors:

Air motors can be stalled at full torque without damage to the motor internals.

Speed control is not as accurate.

The torque output of an air motor is easily regulated by varying supply air pressure. The power density of an air motor is typically greater than that of an equivalent.

If an air supply source is not available then the cost to apply an air motor is higher compared to an electric motor. Depending on the cost of electricity, an air motor’s operating cost may be higher than an electric motor.

WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

There are many different designs of air motors available for selection depending upon the application. As with hydraulic motors, these are classified as high speed, low torque motors or low speed, high torque motors. Some of the most common designs of air motors used are rotary vane, axial and radial piston, turbine, and gerotor. Two other designs are used primary for special applications – V-type and diaphragm air motors. Axial piston motors are used to provide high torque and accurate control at low speeds. They are also capable of generating high starting torque. Radial piston motors are used when there are very high starting loads as they produce the highest starting torque of any motor design. Both radial and axial piston motors require lubrication either supplied in the form of forced lubrication or using lubricated air. Radial piston motors must be mounted in a horizontal position to ensure adequate lubrication is present. Rotary vane motors are used for low to medium power output applications. Their simple design and compact size make them ideal for use in portable power tools. They have a higher power density than comparable piston motors. While there are vane motor designs that can operate with non-lubricated air, the motors most commonly found must use lubricated air and are less sensitive to mounting orientation than piston motors. Gerotor motors are used to provide high torque at low speed without needed additional gearing. The low inertia of the internal rotating group provides for instant starting and stopping or change in direction. The design of the gerotor motor prevents coasting or being back driven and may eliminate the need for an external brake.

WWW.IFPS.ORG • WWW.FLUIDPOWERJOURNAL.COM

Turbine motors are designed such that there is a minimum of internal friction and thus require little lubrication. They are typically used where the application requires very high speed, but the starting torques is low. These are commonly applied to dentist drills or as starters for jet engines. They are more tolerant of contaminates in the air than other motors due to their design. Operation of a turbine air motor involves a nozzle that guides and meters air to a turbine wheel/rotor. The nozzle changes high-pressure, low-velocity air flow to a low-pressure, high-velocity air stream directed against the turbine wheel to cause rotation. The overall efficiency of a motor is determined by the ratio of the actual output power to the theoretical output power. The highest overall efficiency air motor is typically a turbine design due to the lack of sliding parts contact which result in internal friction and lower the efficiency. The theoretical torque output for an air motor of given displacement is a function of the differential pressure. This means that torque theoretically does not vary with a change of speed. In actual practice, as air flow increases through the motor, pressure losses in the inlet and outlet lines along with internal leakage consume a greater portion of the air supply. In practice, torque reaches its greatest value shortly beyond zero speed and drops off rapidly until it reaches zero at the maximum rated speed of the motor at no-load. The maximum torque the motor can produce under load is referred to as the starting torque. Typically, this is about 75% of the rated stall torque. It takes more torque to start a motor rotating under load than to keep it running. If the load on the air motor exceeds the starting torque capability, the motor will not start to rotate. •

CANFIELD CONNECTOR DEVELOPS CUSTOM DESIGN FOR

CONVEYANCE TECHNOLOGY

By Todd Harmon, Vice President, Canfield Industries

ountless industries across the United States rely on conveyor belt systems. Modern manufacturing and logistical operations depend upon efficient conveyance systems operating in the background both day and night. Conveyor systems are utilized to quickly transport goods of every sort, from raw materials in factories to finished goods on store shelves.

The OSV

November 2023

These vital components of modern industry are designed and built by conveyor system manufacturers who have the task of helping their customers move product in a way that is both quick and efficient. A large piece of this puzzle is using modern technology to ensure that products are not damaged or lost as they move down the line. A lack of proper control for conveyance systems produces a cascading negative effect to the operations of the entire system involved. Without precise control, operators within a conveyance system may experience inconsistent spacing, misalignment, or even a product jam. This can result in damage to the product, costly downtime, and delays. Products traveling erratically may even result in safety issues for personnel or a missed deadline for customer deliveries. All in all, proper automation for conveyor systems is vital in modern day industrial operations and requires careful harmony of sensor technology and valve integration for conveyance control. This need for reliable automation led one manufacturer of conveyance systems to reach out to the

experts at Canfield Connector for help in designing a system with the ability to effectively sense and control the flow of product for their end users. Canfield Connector was challenged with development of the optical portion of the design to supply an electrical output to trigger a pneumatic signal. Using the in-house capabilities of design, board manufacturing and injection molding, Canfield Connector developed a custom optical solution that adapts directly to the customer's conveyor channel. Canfield Connector then partnered with Spartan Scientific, a division of Canfield Industries, to produce this optical sensor and valve combination that would be named the OSV, Optical Sensor Valve. Spartan Scientific used their design team to develop a custom valve body that allowed the entire device to mate with the electronics and again attach to the customers conveyer. The team at Spartan designed an innovative solution for the OSV that also allowed the valve to mate with additional units downstream in order to ensure proper product flow all throughout the system. WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

How the OSV Works The concept behind the OSV is a simple use of optics that trigger pneumatics. The optical sensor sends a beam of light to a reflector up to six feet across the conveyer bed. Within the electronic circuit there is an adjustable dwell setting that allows the user to make adjustments to their specific requirements. This adjustment controls the length of time a package is permitted to sit in front of the optical sensor. Once the beam in broken and the dwell time is exceeded, the electronics control the pneumatic valve which then sends an air signal to the previous bed of the conveyer. This signal pneumatically raises the roller system off the drive unit by using small puck like cylinders, stopping the movement of any product in the previous zone. A valuable component of this design is a hallmark for many of Canfield’s projects for their customers worldwide: a retrofittable design. Making the OSV retrofittable to the customer’s product brought immense value in both time and cost. The customer was able to use

existing hardware and also service and upgrade existing installations. Creating an easy to install product is a consistent win for those who are looking for a solution that works well with systems already in place.

A Product of Communication The OSV was a result of careful collaboration between Canfield Connector and the customer, as well as collaboration with Spartan Scientific. This process required a deep commitment to listening to the needs of the conveyor belt manufacturer and to understand the intricacies of the problem. By beginning with a thorough assessment of the manufacturer’s operational requirements, the engineers at Canfield Connector were able to begin designing a solution that would marry innovation and practicality. The OSV came as a result of intentional partnership between the team at Canfield Connector and the experts at Spartan Scientific. This customer-centric approach led to a custom-built product to help this customer guarantee precise control of product by means of modern electronics control and valve technology.

The OSV with Patch Cord

Cutting edge advancements are moving our world forward in every way, especially in areas that may be behind the scenes for most of the population. When moving forward requires electronic control and valve technology, Canfield Connector and Spartan Scientific will work to bring the innovative solutions that a changing world requires. •

Here is the solution to Figure It Out on page 5 In all the years I have been teaching, it still amazes me that most technicians don’t understand the function of solenoid valve #1’s function. The 1000 PSI main relief valve is of the pilot operated design and if the “Vent or X “port is directed back to tank, the relief opens and the only pressure attainable is caused by the 25 to 50 PSI bias spring. This circuit relies on the pressure switch signal to load or unload the main relief by controlling the Solenoid valve. If the Pressure switch is set too high, the relief never releases, causing high pressure oil to flow to tank creating excessive heat. Adjusting the pressure switch lower solved the problem.

UPSKILLING IN

FLUID POWER

By Ian J. Ford, Senior Product Manager, CFC Industrial Training

Why We Work

“

What gets you out of bed in the morning?” Let’s face it, this question is a cliché and veiled attempt at finding out what motivates us. What really gets us out of bed? Our jobs. By the sweat of our brow, we exchange physical labor and mental acumen for our pay. Though the snooze button is a stalwart ally, we need to work. It is necessary – and meeting that necessity is good for us, good for our families, good for our communities. The abilities each of us possess can contribute to net gains. Those productive gains can extend far 24

November 2023

beyond the web of our own relationships. Even the mundanity of button-pushing, is a noble effort if done with the right attitude and sense of purpose. The simplest of tasks can have meaning and contribute to the sum of human enterprise. We get out of bed to do good work. Our work must be effective though. If you are button-pushing on a machine that is off, what does that avail? The more capable we are and the more skills we have, the more valuable our work. Not just for our own sense of purpose, edification, and satisfaction; but also, for the

positive effect one’s skilled labor can provide for an employer, organization, or community. A skilled workforce is perhaps the most valuable asset an organization can have. One could argue, competent employees outweigh equipment, intellectual property, and even capital as a strategic asset. We often see this exemplified in dramatic stock market swings when key employees depart a publicly traded company. This may make one think, “Would I cause a stock market swing if I depart?”. You may laugh at such a ponderance, but if it is asked

the mega-stadium to the steel mill; the humming hero that is an HPU is energizing a tried-andtrue technology that serves as the workhorse of manufacturing and so many other applications. You name the sector, fluid power is there, and usually in no small capacity. Somewhere along the line, fluid power is a tool we use to get the job done. However, it takes a competent team to keep that workhorse running full-bore. As such, the fluid power professional is an integral member of many operations’ workforce.

was exemplified seldomly as a method of power transmission. This is the crux of the matter: new hires, and often many seasoned technicians and maintenance personnel, are deficient in core fluid power concepts and best-practices. The workforce should be the most valuable

Is the Average Hire Competent in Fluid Power? Despite the overwhelming prevalence of fluid power, to many seasoned mechanics, it remains a ‘dark art’ (forgive the diabolical term). A task as simple as changing a hydraulic hose, for example, requires adherence to some important best-practices. As of July 2023, the ASE (The National Institute of Automotive Service Excellence) had 221,933 individuals with some degree of certification. As of this writing, the International Fluid Power Society (IFPS) has 5,581 individuals with some degree of certification. This is not to make an apples-to-apples comparison in certification, these are different disciplines indeed. Rather, we see that although almost a quarter million individuals can be considered certified mechanics or technicians, their capabilities with hydraulic or pneumatic componentry and systems cannot be verified. Conversely, of course, the IFPS-certified individuals provide great confidence to an employer or organization that they have at least some degree of fluid power knowledge and capability. With the aforementioned prevalence of fluid power in industry, this perhaps illustrates the rarity of readily hirable fluid power professionals.

Fluid Power Skills Gap

with humility and sincerity, what an excellent and introspective self-enquiry! Does my work really make a difference? Am I satisfied with what I can contribute? Do the people I work with and for value my work?

Fluid Power is Everywhere Let us consider the pervasiveness of fluid power in the workplace. It is next to impossible to think of a good, commodity, supply chain, utility, or nearly any form of production or service that does not utilize the ‘power’ of fluid power. From the county fair to the dump truck,

WWW.IFPS.ORG • WWW.FLUIDPOWERJOURNAL.COM

Many candidates for the industrial workforce may consider themselves mechanics, or in some capacity may even be certified as such. However, when it comes to fluid power componentry, equipment, and systems, these prospects and new hires are often confronted with an unexpected skills gap. The unique physics involved in fluid mechanics are not exceedingly complex in concept, but they are much less known. Do you recall learning about simple machines in elementary school? Screws, levers, pulleys? Do you recall in high school studying Ohm’s Law? Working with a multimeter in shop class or a lab? Or even simply studying static electricity, grounding, and other fundamental electrical concepts? What about Pascal’s Law though? Perhaps you were exposed to fluid mechanics, and hopefully so. It is likely though, that fluid power

asset to an organization. When it is not, it is usually due to size or lack of capability, and the ramifications can be painful. On-the-job training or ‘upskilling’ becomes imperative, and the return on investment and time-spent is invaluable to productivity. The fluid power professional becomes just that with training. Whether you are an individual looking for a job, or an organization needing to improve employee proficiency and bring new hires up to speed, the skills gap must be bridged. Obtaining the qualifications needed to contribute as a worker with aptitude is simply essential. We train for safety. We train for productivity. We train for efficiency. We train for the bottom line.

For Safety Contrary to the old adage, “ignorance is bliss”, when it comes to working with heavy machinery and powerful hydraulic systems, “ignorance is dangerous”. If for no other reason, familiarity with how fluid power systems behave is integral from a safety standpoint. Even when power is seemingly removed from a system – motors off, pumps off, valves deenergized; trapped pressures can still be present. A generic shop safety class rarely touches on the nuances of hydraulic and pneumatic systems. Asphyxiation, injection injuries, lock-out/tag-out – all important topics. What about outrigger cylinders on a hot summer day? Or utilizing accumulators for emergency power? Even basic familiarity with fluid mechanics and the various componentry in a fluid power circuit puts a technician in a safer situation. The more one understands about the system, the less likely an accident occurs.

November 2023

For Productivity and Efficiency If “knowing is half the battle”, the battle is half-won with proper fluid power skills training. Hydraulic systems are extremely robust, powerful, and can be quite efficient. Maintaining them in peak operating condition requires a knowledgeable team. Fluid cleanliness, leak prevention, proper replacement and installation of conductors and connectors; are just some of the most basic items on a maintenance check list. Proper sizing and installation of wear items such as filters and changing them at the proper intervals is a simple first-line defense against very preventable issues in a system. If a task as simple as this is neglected or performed improperly, productivity can drop. An easily combatted problem such as fluid contamination can lead to defective part production, slower cycle times, wasted material, increased power consumption, amongst other costly and deleterious effects on whatever job one is trying to accomplish. If a maintenance technician of 5 years has faithfully replaced the 10 micron filter with a 10 micron element that has a Beta ratio of 20, when it really needed to be 200; that may be the cause of significant issues in the system. It doesn’t matter how fastidious the technician was in performing the task at regular intervals, the element was wrong. The consequences in productivity and efficiency over the years were probably severe, but entirely avertible. Even the best employees can cause costly problems in a hydraulic system if not armed with a bit of knowledge.

For the Bottom Line Do we dare extrapolate the cost of improper equipment maintenance and operation? Ultimately, skill gaps are expensive. When confronted with downtime or ‘wrench time’, an inoperable system is not contributing to

November 2023

whatever work needs to be done. Let us consider some possible scenarios. Building upon an example of contamination due to improper filter specification, imagine that the contamination damaged a piston pump beyond repair. A pricey replacement. Perhaps the pump is obsolete, and the original manufacturer is out of business. Now the team must also specify an adequate replacement. Does the team have the ability to type and cross the old pump with a modern one? The lead time on new componentry in today’s day in age, can be frustratingly drawn-out. Then take into consideration what is necessary to properly start-up the retrofitted system. What if downstream equipment encounters problems? The team replaces an entire solenoid-operated directional control valve to later find the cabling for the command signal had been severed amidst the retrofit work. Improper troubleshooting can be extremely costly, especially when the stress of an inoperable system is looming overhead. Throwing money at swapping out components is seldom the answer. Just as blindly turning adjustment knobs to get the machine to ‘just work’ is naïve and dangerous. A trained fluid power professional knows how to specify and install replacement components. They know to inspect seals and O-rings, to torque bolts properly, and so many small and simple practices that can prevent much grief and expense. They know to maintain and reference pertinent documentation on components, and the system as a whole. Skills training, even for two or three days, can instill core concepts that remain long after.

Hands-On Skills Training Fluid power skills training is the sure-fire way to bolster the workforce. If we are to contribute and have meaning in our day-today - competency is key. Hydraulic training is best taught hands-on, just as it would be encountered in the real world. Concepts such as pressure vs. flow ‘click’ when exemplified in a demo circuit. Examining take-apart and cutaway components reveal the inner workings of parts and aids in the understanding of their operation. It also easily displays areas potentially affected by wear and/or contamination. Hands-on labs can illustrate concepts such as Sequence Circuits, Meter-In/Meter-Out, and Accumulator Power; preparing the worker for these operations in their own equipment. With determination, the fluid power student can progress from new hire to IFPS-certified in rapid fashion, all whilst on-the-job. Continuing education and ‘upskilling’ keeps the worker engaged in the industry, progressing in the workforce, and all-in-all a valuable contributor.

Education Technologies In the modern workforce, especially when confronted with rapid turnover and the retirement of senior staffers, we must secure our access to essential information. Relying on the ‘tribal knowledge’ of a senior maintenance supervisor is precarious. As the wisdom of trained and experienced team members departs, often the remaining members are left with insufficient or nonexistent data. Documentation and information are essential. Incorrect or partial documentation is, perhaps, just as detrimental as none at all. Even skilled technicians can be adrift without accurate prints. So, capturing ‘tribal knowledge’ and reverse-engineering equipment becomes an essential part of continuing education. As new workers hire in, they can reference critical information quickly, and become familiarized with equipment faster than ever before. Documentation, photography, prints, video, all aid in capturing critical system data in a lasting way. The opportunity to continually learn and share crucial information with staff is an incredible advancement. The technology is readily available and should be utilized. Pairing such education technologies with hands-on training is all the more advantageous, and a scheduled learning and development program can be formed to upskill workers.

Empowering the Fluid Power Workforce Learning and development is often an afterthought. When the going gets tough, a worker reflectively looks for modes of improvement. A company may reactively train a team when a deficiency in personnel appears. However, training should be thought of as an investment, and a comprehensive learning and development program leads to compounding interest on that most valuable asset; an empowered workforce. We must view training and education as a tool for advancement, not remediation. If we want our work to be more than a paycheck. If we want our team members to be more than automatons. Each of us must strive to improve ourselves. We can continually grow as fluid power professionals; collaborating to most effectively wield the awesome technology that is fluid power. When we then turn in after a hard day’s work (or a hard day’s night for you third-shifters), do we feel accomplished? Did our work really do something, even if small? No matter how indirectly, did our job today contribute to our family and community? We who work in fluid power, from the new hire restocking a spill kit, to the senior engineer, should be able to confidently answer, “Yes, and tomorrow we will do all the better.” • WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG
