OVER THE PAST 10 YEARS, as I have visited customer sites to review issues for leaks, engineering services, and reverse engineering of hydraulic and pneumatic. I have heard a growing number of customers and end-users voicing their concerns about how messy their equipment is, how costly hydraulic oil is to keep adding to reservoirs as it leaks and how expensive energy costs are to run pneumatic and hydraulic systems when such inefficiencies exist. The question is often asked, "CAN WE REPLACE THIS EQUIPMENT WITH SOMETHING ALL ELECTRICAL AND CLEANER? " I always respond by asking about their preventative maintenance programs. To me, these programs are like getting your annual physical exam with your doctor. If there is something wrong, it can be addressed and fixed before it gets too costly and messy.

All too often what gains a hydraulic or pneumatic system attention are the messes they create by poor maintenance and the high cost of upkeep. Both of these issues can be addressed and fixed by simple preventative maintenance programs that stop leaks and help keep energy waste at a minimum, not to mention the cost of hydraulic oils, utility bills, and the potential for hazards—slip, injection, and environmental hazards. Add all of this up and it just makes good common sense and safe practice to have your hydraulic and pneumatic systems scheduled for a yearly exam with the “doctor.” Treat your fluid power systems health just as seriously and continuously as you treat your own health.

Let’s keep our industry clean and under those radar screens that make customers and end-users ask about the alternatives. Together with a common sense approach and proper preventative maintenance programs and practices, we can keep people and the environment safe, and show our employers and customers that we, as industry professionals, take our fiduciary duty seriously.

Stay clean out there! 

THE DEMAND OF INDUSTRY 4.0 Industry 4.0 started the trend towards automation and data exchange in manufacturing technologies for a smart factory concept where we monitor physical processes in real time—in short, the computerization of manufacturing. Most notable of all these changes is the Industrial Internet of Things (IIoT), which is the integration of smart technology through interconnected sensors, instruments, and other devices networked together with computers, PLC’s, and network components. The economic benefit was clear – data collection, exchange, and analysis. The real benefit to most factories was the predictive maintenance piece and how to extend service life through maintenance and repair while reducing down-time and premature failures. Understanding the inner workings of an actuator became paramount to both safety and the function of machinery. As a result, industry grew closer to better solutions for position sensing.

IIoT AND THE AUTOMATION OF CYLINDERS

IN THE FLUID POWER INDUSTRY

By Linda Caron, Global Product Manager, Parker Hannifin

ADDRESSING THE PROBLEM Cylinders have been the workhorse of industrial machinery since the late 1700s. These devices are used to transfer energy through linear motion and have undergone significant change over the years, including methods of construction to reduce size, materials used to reduce weight, and advanced sealing systems to minimize leakage. Plus, the use of composites and special engineered materials increase life expectancy by reducing wear. Yet, one design challenge remains: how to best determine the position of the piston.

JANUARY 2020

Linda Caron is a Global Product Manager for Parker Hannifin Corporation in Factory Automation, Pneumatic Division, Motion Systems Group in Richland Michigan.

Caron is a CMSE®, Certified Machinery Safety Expert (TÜV Nord) and has held various roles over 27 years in both Fluid Power and within the electrical industry, serving global markets from oil and gas to the food and beverage industry.

Caron’s focus is on the IIoT space, network connectivity, and machinery safety.

HISTORICAL METHODS Many methods unfolded over the years on the topic of piston sensing (each industry wrought with its own challenges). The early days had no sensing capability. We were just happy the cylinder stroked and moved the load! Advancement took us to proximity style switches at a cost of about $300 a piece and had to be drilled into the head and cap of the cylinder. Applications requiring greater accuracy opted for the gun drilled LVDT whereby, a hollowed-out rod allowed for the insertion of a transducer. Quite an anomaly when you needed to rear mount with a clevis! Many methods were also utilized to sense displacement of pressure from the head or cap side of the piston to determine within reasonable accuracy the pistons location mid stroke. Reed switches were a cost-effective way to sense the piston with an embedded magnet on the piston itself. While cost effective, reed switches were limited to only end of stroke sensing. Smart technology demanded a better way.

We Make Valve Automation Easy!

Automated Valves from Stock Built, Tested, Shipped - Same Day

NEW METHODS Continuous position sensing (CPS) has become popular today for outstanding performance to price. Available in digital or analog, these sensors are inexpensive and easy to install (with no cylinder modification) Environmentally, they are resistant to ingress, shock, vibration, and stray magnetic fields. The robust nature of this simple cost-effective product has made it a leader in machine technology.

Instead of end of stroke, you can now adapt continuous positioning sensing from 32mm to 256mm (1.25” to 10”). CPS can be used anywhere and are very commonly sourced for industrial machinery. Simply plug them into an IO-Link master for easy real-time feedback on the network. This offers a tremendous advantage over the traditional linear positioning technologies. Safety is also enhanced for those applications where feedback of piston position is critical to indicate a safe, at rest or mid position of an actuator.

Compact On/Off Valves

High-Cycle Ball Valves

For Lower Pressure Water, Oil, Gas, and Steam OEM’s, integrators, and factories all over the world are turning to Assured Automation’s compact on/off valves and high-cycle ball valves to improve machine reliability and increase productivity.

ic OptimizerTM

Flange Mounted Relief Functions CONCLUSION Now we can find the position of the piston and communicate with it quickly, easily, and with little cost. Coupled with the benefits of decentralized machine design and IO-Link technology, CPS enables a smart factory to be quickly born with easy integration and little cost. The average factory is easily adaptable with these types of components to be IIoT compliant or at least to know when their cylinder is in a safe position before starting a secondary operation. Most new cylinders are available with incredibly short lead times (often same day shipping) while new technologies like CPS provide incredible advantage for predictive maintenance, easy upgrades and enhanced safety. 

New Problem: Ram Falls on a New Installation

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

Âť

A NEW PRESS was installed in a factory that makes steel bumpers for over-the-road tractors. The hydraulic power unit was supplied by a local hydraulic distributor that would only control the main ram supplied by the press manufacturer. The factory had a central system that would control all the auxiliary actuators on the press.

When everything was assembled on the plant floor and commissioning was started, they found that the main ram would not stay up in the neutral position. No matter what position the ram was stopped, it would fall to the fully extended position. They also lost pump pressure.

The power unit builder assured the customer that they tested the unit with one of their cylinders laying on their shop floor and it functioned well, extending and retracting as designed.

Any idea why the ram falls in the neutral position?

S

olution to the previous problem: Pressure-reducing Valve Would Not Reduce The Pressure

When pressure reducing valves adjustment knob is hard to turn, it normally is due to the spring chamber seeing hydraulic pressure. This pressure is also an additive to the spring adjustment setting. When we inspected the unit, we found the pressure supply and return connection were plumbed up backwards.

Energize the Field of Pneumatics

SMART-SENSOR NETWORKS, OPTIMIZED ELECTRIC AND PNEUMATIC ARCHITECTURES, CONFIGURABLE DEVICES, AND IIOT ARE THE TRENDS HAVING THE GREATEST IMPACT.

Four technology trends have amplified the importance of pneumatics in automated systems.

These developments have given this low-cost source of motive force new life and are evolving pneumatics for service in the 21st century. The four trends are:

MODULAR MANUFACTURING WITH CONFIGURABLE DEVICES

INTELLIGENCE OPENS THE DOOR TO GREATER PRODUCTIVITY

HIGHPERFORMANCE INTEGRATED ELECTRIC AND PNEUMATIC ARCHITECTURES

INDUSTRIAL INTERNET OF THINGS (IIOT)

One of the issues concerning pneumatics today is the difficulty of collecting device data. However, now with the application of low-cost intelligent sensor networks such as IO-Link, it’s feasible to accumulate data from pneumatic devices. Assured data acquisition increases control and ensures better overall performance. Furthermore, a new class of valves – intelligent valve packs – feature integrated microsensors for pressure and flow. Data from microsensors provide new opportunities in adaptive control that were simply not practical before the digital revolution. The application of intelligent devices will continue to support and further pneumatic solutions.

WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

FUNDAMENTAL ADVANTAGES ENSURE THE STAYING POWER OF PNEUMATICS

Modular manufacturing offers a solution that lowers overall cost and lead time for new lines.

Compressed air systems are low-cost compared to electrics, as well as simple to install, commission, and maintain. When compared to electric actuation, pneumatics provides a higher force density per form factor.

Pneumatic actuation operates at high speed, and is the solution of choice for harsh environments where dust, dirt, moisture, washdown, or explosive particles or gases are present. All of these factors make pneumatics relevant for automated systems.

Intelligent sensors and the latest control, communications, and motion technologies enable IIoT.

MODULAR MANUFACTURING AND DEVICE RECONFIGURATION REDUCE THE COST OF NEW MANUFACTURING LINES Shorter product lifecycles place cost pressure on manufacturers due to the enormous capital and resource expense of specifying, purchasing, and installing production lines for every new product. Modular manufacturing offers a solution that lowers overall cost and lead-time for new lines.

In modular manufacturing, each module in the system is dedicated to performing one or two simple production steps – for example, screw driving, part insertion, or adhesive application. By arranging relatively simple and low-cost modules into a unified line, the product is manufactured one step at a time. Smart conveyors enable modular manufacturing by routing workpieces to the appropriate module for a required step. When a line is decommissioned, modules and conveyors can be reconfigured and reused, which leverages the original investment and decreases implementation time.

Modular manufacturing is one of the foundational concepts of Industry 4.0.

Intelligent pneumatic valve packs also contributed to efficiencies in modular manufacturing. Intelligent valve packs change functionality via downloadable software apps. For example, an intelligent valve pack can change its function via software from a 2-2 valve for a robotic vacuum gripper to a 3-2 valve for a mechanical gripper utilizing the same valve-pack hardware. Or that same valve pack could be reconfigured for flow control of cylinder speed or for minimization of energy consumption during the extend and retract stages of actuator movement. Every module with reconfigurable devices, such as intelligent valve packs, becomes more flexible.

Intelligent valve packs change functionality via downloadable software apps.

UNIFIED ELECTRIC AND PNEUMATIC ARCHITECTURES OFFER OPTIMUM PERFORMANCE Suppliers have invested in the development of controllers and other hardware and software that seamlessly integrate pneumatics and electrics within a high-performance motion architecture. These systems feature the latest developments in Remote I/O that not only help drive intelligence deeper into the machine, but also improve pneumatics performance by allowing valve terminals to be located nearer to actuators for faster response time.

Remote I/O also makes installation and troubleshooting easier and less time consuming. Mixed electric/pneumatic motion systems are not new. What is new is the application of the latest control, communications, and motion technologies within the overall control architecture.

ABOUT THE AUTHOR

IIOT GATEWAYS ARE ESSENTIAL FOR GAINING THE ADVANTAGES OF INTELLIGENT SYSTEMS Intelligent sensor networks; high performance, unified electric/pneumatic control architectures; and modular manufacturing are the building blocks of IIoT. State-of-the-art IIoT gateways bring these three pieces of technology together and provide a secure interface to cloud computing. Once an IIoT gateway is added to a system and dashboards are created, authorized personnel can access operation data for use in predictive maintenance, faster issue resolution, process optimization, and energy minimization.

With cloud computing, the organization becomes more fully integrated, responsive, and efficient. Data from deep within the process, supplied by intelligent sensors, can lower the incidence of unexpected machine stoppages. As artificial intelligence costs come down, adaptations to the environment as presented by cloud analysis will become even faster. A cornerstone of these IIoT-based systems will be machines that blend the advantages of both electric and pneumatic motion within an intelligent unified architecture. 

Case Study

IMPROVING ASSEMBLY for Fluid Power Components

By Jim Kressler, Director - Facilities, Bosch Rexroth Corporation

Manufacturing fluid power components such as valves and manifolds requires a lot of flexibility to accommodate different customer requests in an efficient manner. To help achieve this goal, Bosch Rexroth recently implemented a new MultiProduct Line (MPL) that combines automated and manual systems with Industry 4.0 (i4.0) technology that connects operators, machinery, and parts to make 34,500 different product variants. The result has been a significant increase in productivity, coupled with invaluable experience gained in the deployment of forwardthinking “Factory of the Future” technologies.

Employees use the ActiveCockpit to meet for 15 minutes at the beginning of every shift to review the previous day’s data and plan out the day accordingly.

26

JANUARY 2020

MANUFACTURING EXECUTION SYSTEM The manufacturing execution system (MES) is centrally located in the plant and is responsible for collecting, filtering, and continually displaying production data. Since the MES is consistently running, it plays a crucial role in managing the MPL by providing operators and managers with immediate status updates from all areas of the line. The MPL uses the company’s ActiveCockpit technology to visualize production data from every corner of the plant on a single 65” screen.

Employees can also access the information from mobile devices, laptops or tablets.

Since operators and managers can access the information from anywhere in the plant, ActiveCockpit can alert them of a problem, allowing them to take corrective action no matter where they are, reducing downtime and minimizing error. Employees use the ActiveCockpit to meet for 15 minutes at the beginning of every shift to review the previous day’s data and plan out the day accordingly. ActiveCockpit’s built-in functionality includes the ability to run meetings, including attendance, record and store meeting minutes, and send the notes to absent attendees. ActiveCockpit is also configurable for unique applications.

RADIO FREQUENCY IDENTIFICATION TAGS Industry 4.0 involves automated technology to support the worker in his or her everyday tasks. The key to effectively doing this is customization. Each worker on the MPL has a name tag with an embedded Radio Frequency Identification Tag (RFID). The individual workstations throughout the MPL are programmed

to read the RFID tags and adapt the workplace to their skills and preferences. This includes ergonomic initiatives such as height-adjustable benches to providing instructions based on the worker’s level of experience. The RFID tag can connect with workstations to initiate material requests or assembly instructions on behalf of the worker, allowing employees to focus on creating high-quality products.

Using RFID tags, the company ensures that each employee can work in a space designed specifically for his or her needs, increasing worker productivity and comfort. The same technology that customizes employee work processes also assists with identifying the product variants as they come down the line.

All products made on the MPL have a unique identification tag. As the products move down the line, the product’s RFID is closely monitored by the production control system to trigger replenishment of components when necessary. Additionally, product carts are identified by RFID tags and alert automatic guided vehicles (AGVs) to automatically pick up materials for the next production cycle.

LIGHT GUIDED SYSTEM Once the workstation has identified the worker with the personalized RFID tag, the instructions for assembling the current product are beamed onto the station with a light guided system (LGS). Since the workstations are customized to the individual, the LGS displays the instruction with the level of detail appropriate for the worker’s level of experience.

When executing an assembly task, the highest WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

The MPL mixes automated and manual systems with technology that connects operators, machinery, and parts to make 34,500 different product variants.

risk from a quality perspective is whether the right component makes it to the right spot at the right moment in the assembly operation.

To combat this challenge, the light guidance technology is equipped with a camera and sensors to confirm that operators move forward with the operation per the specification. If the camera detects that the operator is about to use the wrong piece in the wrong sequence, the LGS prohibits movement further in the instructions when it senses the inaccuracy. With its built-in scanners, the LGS has the ability to read the RFID tags of products, activating the instructions for that product to be displayed.

NEXEED PRODUCTION PERFORMANCE MANAGER In contrast to the MES, which is mainly utilized for administrative documentation, the Nexeed Production Performance Manager (PPM), a software solution developed by Bosch Software Innovations, is installed in the MPL to monitor manufacturing processes. The PPM is designed to help users to visualize data in real time and has the capacity to track the many sensors integrated into the MPL, allowing it to measure features such as temperature, flow, pressure, vibrations, torque, sounds, and other operating characteristics. Like the MES, the PPM is customizable to a plant’s unique application.

With the PPM, users can apply pre-determined thresholds, or “rules,” to the data to ensure the plant is running efficiently. If a “rule” is crossed, the PPM can automatically issue a ticket and alert an appropriate employee with the right qualification and responsibility to deal with the affected machine for an immediate resolution. For example, if the PPM senses that hydraulic filters are clogged and the data shows performance levels below the threshold of a properly functioning filter, an alert is automatically issued to ensure quick action to address the problem. The ultimate goal is to get ahead of the maintenance process, minimize downtime, and ensure the equipment is always performing at its peak. In conjunction with a maintenance support system, the PPM can also provide diagnostics and recommend the ideal repair strategy from its knowledge database to maintain continuous operation.

being utilized on the MPL is available for other companies that want to implement i4.0 in their own operations. The technology we added to our multi-product line is exactly what we needed to meet our objectives. Plus, we’ve gained invaluable firsthand experience with connected technology’s ability to enhance productivity and efficiency in assembly operations, parts supply, worker guidance, and quality control. 

INTRODUCTION

In fluid power systems, valves are commonly used to control the tools and output of machines. Many models, sizes, and types exist to offer numerous control capabilities. Vacuum shares this same concept where valves are primarily used to turn a vacuum on and off, or to relieve and maintain pressure. The following article is a general overview of vacuum control valves and their use in manufacturing production facilities.

Figure 1: 2/2 (2-way) normally closed spring return vacuum valve

2/2 AND 3/2 TYPES

The most popular vacuum valve models are 2/2 and 3/2 (2-way and 3-way). The first number represents the number of ports and the second indicates the number of valve positions. Ports/positions notation is the standard designation to identify the basic functionality of a valve. For arguments sake, let’s consider all valves in the following content to be spring return as they are by far the most common in vacuum applications.

2/2 valves have two ports and two positions. The 2/2 model can be thought of simply as a “stop and go” valve. In one position, the valve is closed and vacuum is OFF, and in the other position, the valve is open and vacuum is ON. If the rest position of the valve is closed, the valve is referred to as normally closed (NC), whereas normally opened (NO) is the opposite. A normally closed unit requires the valve to be energized to open and turn the vacuum on. The choice of NC or NO is usually decided based on safety requirements of the system. During a power loss, the valve rest position is key to determine how the system will react. Figure 1 shows a typical 2/2 valve and its symbol. An example of a 2/2 valve application would

be turning the vacuum on periodically to increase the vacuum level in a storage tank.

3/2 valves have three ports and two positions. They turn the vacuum on and off just like the aforementioned 2/2 valve, but there is a third port to exhaust vacuum from the application. If we consider a normally closed 3/2 valve, the vacuum source is closed off while the application is open to atmospheric air. If the valve is energized, it changes positions so that the vacuum source is connected to the application and the exhaust port is blocked off. If we then de-energize the valve, the vacuum source is shut off and the application opens to the exhaust. During this transition, atmospheric air is introduced to the application and the vacuum decays. The normally opened version would have the reverse conditions.

Figure 2 shows two 3/2 valves and their symbols..

Direct acting and pilot assisted actuators will be covered in the following section. An example of a 3/2 valve application would be using vacuum cups in a pick-and-place system where vacuum needs to be applied to the cups to lift the part, then exhausted to release.

WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

DIRECT-ACTING VS PILOT-OPERATED ACTUATION

Vacuum valves can be direct-acting or pilot-operated. Direct-acting valves are energized and switch positions using energy solely from the powered solenoid. Pilot-operated valves use assistance from compressed air to shift valve positions.

Direct-acting types are typical for smaller valves where a relatively smaller coil can be used to shift valve positions. If the energy required to change positions is reasonably low, the power from the solenoid alone can be used. As valve size increases, the energy required to shift positions increases. Particularly under vacuum since the suction pressure is applying a counter-pull force on the actuator. The larger the actuator area, the more vacuum force is applied, and the more energy is required to overcome it.

Therefore, as the valve size increases, a larger coil is needed or another means of energy can be introduced to allow the valve to shift positions. This is where the compressed air pilot assistance is required.

To counter the vacuum and spring force applied to the actuator, compressed air is used as the energy source to push the actuator to change positions. This design allows for a reduction in coil power. Refer back to Figure 2. It shows two 3-way valves, one is direct-acting and the other has an external air pilot as the motive force.

SIZING A VACUUM VALVE

The first step in selecting a valve is to ensure it is vacuum rated. Depending on the internal design and actuation capabilities discussed previously, a valve may or may not be capable of working under a vacuum. Valve manufacturers provide pressure ratings and will generally state if a valve is compatible with a vacuum.

It is tempting to choose a valve based on its port sizes to match the surrounding components in the system, however it is not necessarily an ideal approach. Vacuum valves should be sized according to their flow ratings to ensure the flow is not being restricted. For example, it is counterintuitive to use a single valve with a flow rating of 10CFM if the pump is producing 30CFM just because the port sizes are equal and convenient. However, using this same example, three valves in parallel will manage 30CFM and allow full efficiency for the selected components. The circuits shown in Figure 3 demonstrate this design approach. Alternatively, a single 30CFM valve would also be acceptable.

WWW.IFPS.ORG • WWW.FLUIDPOWERJOURNAL.COM

Figure 2: Direct-acting and pilot-assisted 3/2 (3-way) vacuum valves

Figure 3: Vacuum valve circuit designs with restricted and efficient flows

Valves specifically designed for a vacuum should have much larger orifices compared to a pneumatic valve. Because of the higher pressures generally associated with standard pneumatic valves, a relatively large pressure drop may still provide an adequate flow. Vacuum valves have a maximum pressure differential of less than one atmosphere.

An acceptable restriction in a standard valve may be too great for a vacuum application, drastically

limiting vacuum flow. This is due not to the port sizes, but the internal orifice within the valve. A typical direct acting pneumatic ½” ported valve will have a 2mm orifice, whereas the same valve configuration for a vacuum will have a 12mm diameter orifice. That’s a surface area multiple of 36 (3.14mm² vs 113mm²).

VALVE LOCATION

The vacuum valve separates the upstream and downstream volumes in a system, so its location affects the performance of the application.

If we consider an application with a fixed pump

position, a vacuum valve installed closer to the application will result in quicker cycle times. (Refer to Figure 4.) To increase the application speed, the goal is to reduce the volume on the application side (V2) so there is less air to evacuate. This also means there is less volume to exhaust, which further reduces cycle time as well. Additionally, the volume between the valve and the pump (V1) acts as a vacuum reservoir so by decreasing the application side volume (V2), the pump side volume (V1) is increased acting as a larger vacuum reservoir.

Placing the valve closer to the application can be advantageous in high-speed vacuum systems such as pick-and-place in the packaging industry, where rates can be over 100 cycles per minute. On the other hand, the valve location in slower systems can prove to be insignificant, such as slow vacuum pick-and-place palletizing machines where only 5 cycles per minute is required.

RELIEF VALVES

Figure 4: Vacuum valve locations

The concept of a vacuum relief valve is quite simple. When the vacuum level is high (low absolute pressure), the valve opens and allows atmospheric air to bleed into the vacuum system to maintain a steady or lower vacuum level. Relief valves are often used in conjunction with regenerative blower pumps to prevent them from going into “over pressure” and overheating, but can also be used for general-purpose vacuum relief. One example would be for gripping a delicate part with a vacuum cup. If high-vacuum level pressure causes damage to the part, the vacuum relief valve can be used to meter and lower the maximum vacuum level. Relief valves are often factory preset, but many have an adjustable mechanism to change the pressure relief setting. Figure 5 shows an example of a relief valve.

CONCLUSION

There are many types, designs, and purposes for vacuum valves and selecting the appropriate model can have a major impact on the application.

This article reviewed concepts and strategies to help guide the reader to a better understanding of vacuum valves in general. Each application is unique and professional assistance should be considered when selecting a vacuum valve. 

When you hear the term “automation” your mind immediately jumps to visions of the future. How can fluid power technology that has existed for hundreds of years be part of something that is considered cutting edge?

In 1648, French physicist Blaise Pascal introduced Pascal’s Law. The law states that a pressure change at any point in a confined incompressible fluid is transmitted throughout the fluid such that the same change occurs everywhere. In 1795, Joseph Bramah patented the first hydraulic press in England. This was the beginning of the Industrial Revolution.

Today it is difficult to imagine a world without cylinders as fluid power is used to produce a large amount of power using pressurized fluid.

Some industrial applications include: • Loading/Unloading • Packaging • Welding • Painting • Lifting

Air Cylinder

Hydraulic Cylinder

When heavy loads are required, hydraulic cylinders offer higher force and coupled with electronic technology, the cylinder is programmable to accuracy and resolution within .001 of an inch.

It’s common to see hydraulic, pneumatic and electric cylinders working in unison to provide the best of all worlds.

Hydraulics are chosen in heavy duty applications where air cylinders are typically chosen for medium duty, low-cost applications. Electric cylinders are also used in lighter duty applications, such as food processing where speed, cleanliness and accuracy are crucial.

Three of the most common cylinders used in robotic applications are pneumatic, hydraulic and electric. Take a look at the pros/cons for each type below.

AIR CYLINDERS

PROS: Allows for greater speed; limited with control and stability.

CONS: Complete system requirement to operate a cylinder can be costly.

HYDRAULIC CYLINDERS

PROS: Plenty of power where stability and high force is required: best for harsh environments.

CONS: Requires regular maintenance. Leakage is the most common issue that can be controlled with maintenance.

ELECTRIC ACTUATORS

PROS: Clean, strong, and quick; has accurate positioning/control.

CONS: Limited in force compared to air and hydraulic cylinders.

Can be expensive with complex designs, not suited for all environments.

Although electric actuators were expected to dominate the fluid power industry, hydraulic and pneumatics have made significant performance gains to remain competitive.

The National Fluid Power Association (NFPA) provided an estimated breakdown of cylinder market share for Air vs Hydraulic. It’s also interesting to take a look at how hydraulic cylinders vary across industrial and mobile applications.

When specifying a type of actuator, take into consideration the load to be moved as well as the speed. At the end of the day, the application, budget, and environment will play critical roles in choosing which cylinder type would be the perfect match. When in doubt, explore the many caveats with an experienced engineer to ensure your project is successful.  WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

Updates to

ISO 8426 An ISO Standards sub-committee journey to rigorously study and recommend best methods for determining the displacement of a pump

By Jose M. Garcia-Bravo, Ph.D., Jack L. Johnson, and John Montague

»

SINCE 2018, A GROUP of fluid power volunteer experts has been diligently researching the various methods available for determining the volumetric flow delivery of a pump from experimental data. Two common available standards used for finding the volumetric displacement of a pump are the ISO 8426:2008 standard and the SAE J745-2009-06.

The former normative produces diverse values of the displacement at various shaft speeds, and the latter produces different displacement values at various pressure levels.

The aim of the 8426 standard is to produce a single numerical value which represents the volume of fluid displaced per shaft revolution. Multiple articles authored by fluid power academics have highlighted the inaccuracies incurred when using the current ISO 8426:2008 standard. [1-5] Moreover, the authors of this article recognize, as others have pointed out, [3],[6] that the pump or motor clearances within the unit are affected by pressure, and the compressibility of the fluid make the effective displacement of the unit a non-constant value.

This is now especially true for pumping devices that rely on partial compression of the WWW.IFPS.ORG • WWW.FLUIDPOWERJOURNAL.COM

fluid chambers such is the case of digital displacement pumps. Setting those observations aside, and for the practical purposes of the ISO 8426 standard, the derived capacity or derived displacement is defined as a single scalar value obtained from steady state measurements.

Members of a technical group revising this ISO standard are now considering the definitions and methods presented in various academic papers, [7],[8] to extend the definition to improve the accuracy of the derived displacement.

The Toet method[7] considers the derived displacement to be a value found after regressing the slopes of the flow versus shaft speed at zero pressure, while the Wilson method[8] characterizes the displacement as the slope of the linear fit for the rate of change of the flow versus shaft speed conditions of the hydraulic unit.

The revising group is now conducting tests using real data from diverse pumps and motors to test the original standard, the two aforementioned methods, and a fourth method that synthesizes the Toet method to one single step using linear regression analysis. As of today, two complete sets of data measurements have been completely processed using all four methods producing results that confirm that the 2008 version of the standard produces inconsistent results, and that the Toet and Wilson methods produce comparable results within 2% from each other for one case and less than 1% for the other.

The study will continue with the inclusion of more real machine data from diverse

manufacturers and designs. At this point, from the preliminary results obtained, the single step method seems to produce consistent results when compared to the other proposed ones, with the added advantage of considering the various effects of the operating parameters, including the pressure-viscosity and the pressure dependence of the pump or motor, as well as being able to accommodate the analysis of the data without the need to sort it, hence allowing for the design of experiments that can randomly produce test data, a highly desirable feature for the creation of true and more meaningful independent statistical samples.  REFERENCES: [1] Post, W.

Manuli Hydraulics launches HydroRope range for grab applications

»

WHEN SELECTING A hydraulic hose for most normal applications, the tensile strength of the hose is not usually a critical determining factor. However, in certain specialist applications, such as the hydraulic grabs used in diaphragm wall building operations, tensile strength can make a huge difference to the operational life of the hose. For this reason, Manuli Hydraulics has developed HydroRope, a 42 MPa premium hydraulic hose with specially enhanced tensile properties making it ideal for use in these situations.

Manuli Hydraulics focuses the design, manufacture and supply of fluid conveyance solutions, components, and associated equipment for high pressure hydraulics, refrigeration and oil and marine applications. The company has over 2,000 employees, with manufacturing facilities located throughout the world. The global sales and marketing headquarters are located in Manchester, United Kingdom. www.manuli-hydraulics.com 38

PIRTEK USA expands in metro Houston

»

PIRTEK USA NOW has five locations spread across metro Houston with the opening of PIRTEK Baytown and PIRTEK Pearland. PIRTEK is the leader in providing hydraulic and industrial hose replacement sales and services to industries including construction, marine, manufacturing and equipment rental.

PIRTEK Pearland is a mobile-only location. The mobileonly, Tier 2 model, allows the franchisee to reduce startup costs by keeping the inventory in a small warehouse or storage facility and leasing two vehicles. In three years, Tier 2 owners typically transition the business into Tier 1, a fully staffed Service and Supply Center location.

Both PIRTEK locations are positioned near port industries, which are expected to be a significant source of business. “Having the port nearby means there are plenty of industries that use hydraulic hoses,” said Dean Akin, who with his wife, Lisa, owns the two new Houston locations. “In addition to that, there’s ongoing construction, especially when you consider the hurricanes that come through here so often. Most of the business is typical of what PIRTEK provides, and there’s plenty of it.” www.pirtekusa.com WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG
