The Aging Standard

By JR (Jon) Rhodes, CFPECS, CFPAI, President of CFC Industrial Training

» WHILE

LEADING

A recent hydraulic training class that involved sizing and standards, one of the participants was frustrated with the system specifications. The participant inquired as to why the fluid power industry lacks standards compared to other industries. The math associated with sizing system attributes is riddled with the duality of imperial (U.S.) and metric measurement scales. This adds complexity to already challenging circumstances. In class, I struggled to quickly provide a meaningful answer to address these frustrations. I explained the big question as to how we’ve arrived at our present circumstance with many detailed answers.

In 1975 when I was in the 2nd grade, President Jimmy Carter appeared on my tube-type Magnavox TV and said, “The United States will convert to the metric system.” I filled up my gas tank, bought some milk, and checked my tire pressure this morning in the most imperial manner. This is not a fluid power-specific issue, as it poses a challenge for many other industries also. Prior to globalization, regional organizations developed standards specific to their global regions and industry requirements. This regionalization was prevalent in

the early days of fluid power and its effects are still wide-reaching today. Of course, there are 231 cubic inches in a gallon and 5,280 feet in a mile; how dare you pose such a question! In Europe, the U.S. customary Olde English imperial measuring systems are loathed. This seems a bit ironic, as Europeans frequently use the bar widely as their “invented” measure of pressure. (100,000 pascals = 1 bar). I’ve also seen the use of cubic decimeters (1 cubic decimeter = 1 liter). No system will ever be perfect, but the verdict is in, and the metric system is superior.

The International Standards Organization (ISO) Technical Committee 131 leads the perpetual journey for a global, unified standard for our industry. They are the preemptive organization for fluid power global standards. At last check, they had 238 developed standards and 31 new standards still under development. The National Fluid Power Association (NFPA) represents the North American market in the Technical Advisory Group (TAG), along with 16 other associations around the globe that form the governing ISO Standards Committee for fluid power. Organically, the use of U.S. customary measurements is slowly declining. ISO standards are driving new applications of fluid power systems to be purely metric. Standardization is about more than just units of measure. It drives the advancement of the industry by providing guardrails for safety and commerce.

Adhering to a single standard can greatly simplify the use of fluid power while removing

the barriers in education that help us apply products and systems. The complexities of fluid power systems are increasing as we continue to push forward. As the industry applies new devices and technology, guiding standards must accompany these technologies for standard communications and performance ratings. Applied and implemented standards for safe operation, interchangeability, and serviceability will help remove unnecessary frustrations and attract top talent into the industry. New technologies that increase efficiency and autonomy will become impossible to service and difficult to sustain without improved standardization.

At each step in the process of becoming an impressive industry, fluid power has advanced through the many organizations and associations that provide guiding standards. In the U.S., the Society of Automotive Engineers (SAE) is still an impressive, influential global institution. The fluid power industry continues to be greatly influenced by the North American market. While the argument of U.S. customary versus metric systems will most surely continue, our progress toward achieving global standardization must not be stifled. Top-down, the need for improved efficiency and safety in our industry exists. It all starts with a common set of engineering practices and compliance. It's important to remember that standards are only worthy if we adhere to them.

» A CUSTOMER HAD a system that required the vertical cylinder to accelerate at different speeds caused by different models of steel bumpers they were forming. They could adjust the cylinder's force remotely but had to climb under a table to adjust the downward speed. They found that both speed and cylinder's tonnage adjustments for the different-sized bumpers decreased their scrap.

The customer decided to fully open the meter-in flow control on the valve stack controlling the downward speed. They installed a line-mounted valve next to the pressure control to increase the operator’s convenience and safety, as well as reduce the time to convert die changes.

The counterbalance valve was located next to the valve stack and the outlet of the new flow control was plumbed directly to the cap end of the cylinder. However, they had problems with the cylinder’s downward stroke shuddering and had to adjust the counterbalance valve to eliminate the new problem.

Any idea what caused the new problem?

CUSTOM

ORDERING CUSTOM HYDRAULIC CYLINDERS

By Sebastien Lajoie, Cylinder Engineering Manager, Bailey International

KEY CONSIDERATIONS

The heart of hydraulic systems lies in their ability to efficiently transfer power through the movement of fluids. This capability depends on the quality and precision of system components. Among these, custom hydraulic cylinders stand out for their ability to significantly enhance system reliability.

In the diverse world of hydraulics, adopting a one-size-fits-all approach falls short. While standard cylinders might suffice for general applications, custom hydraulic cylinders tackle specific challenges head-on and elevate system performance. By opting for custom solutions, you guarantee your hydraulic system is perfectly aligned with the unique demands of your application. This allows for improved efficiency, an extended lifespan, and lower maintenance costs.

Custom hydraulic cylinders are engineered to cater to unique operational loads and specific usage cycles, designed to thrive under challenging environmental conditions. In scenarios where installation space is at a premium, a custom cylinder can be ingeniously designed to perfectly fit the confinement. Conversely, for applications that demand high-pressure functionality, custom cylinders can be developed using robust materials and designs capable of withstanding the most rigorous conditions. These cylinders can be

equipped with special seals, coatings, or other modifications to improve durability in extreme temperatures, corrosive environments, or other harsh operational conditions.

The process of designing and manufacturing custom cylinders involves close collaboration between the client and the manufacturer. A partnership ensures that every aspect of the cylinder, from its dimensions and material selection to its sealing and mounting configurations, is optimized for the application at hand. By considering a project's specific requirements and constraints, manufacturers can deliver custom hydraulic cylinders that meet and exceed expectations, providing a competitive edge in efficiency and reliability.

OPTIONS AND SELECTIONS

Selecting the right material significantly impacts a cylinder’s durability, resistance to environmental factors, and performance in

various applications. Among the common materials used are steel, stainless steel, and aluminum. Each offers distinct benefits and presenting certain limitations.

Steel stands out for its exceptional strength and durability, making it an excellent choice for hydraulic cylinders in heavy-duty industrial applications. A steel cylinder can withstand high pressures and harsh operational conditions. However, steel's susceptibility to corrosion is a notable drawback. This issue can be addressed through the application of protective coatings or by opting for stainless steel in environments where corrosion is a concern.

Stainless steel is renowned for its superior corrosion resistance, an attribute that makes it particularly well-suited for use in environments that are either very moist or where the cylinder might be exposed to corrosive chemicals. Stainless steel also maintains an elevated level of strength and durability. Nevertheless, these advantages come at a cost, as stainless steel is more expensive than its standard steel counterpart. This cost factor may influence the material selection process, depending on budget constraints and specific application requirements.

Aluminum, with its lighter weight, presents an advantageous option for applications that

prioritize reducing weight without significantly compromising the cylinder's integrity. Its inherent corrosion resistance further enhances its appeal, particularly in applications where environmental exposure could degrade other materials. Although aluminum may not match the sheer strength and durability offered by steel and stainless steel, its performance is more than adequate for many applications, especially those where weight considerations are paramount.

The cylinder and bore size are critical factors that must be defined to ensure the cylinder's efficacy in generating the requisite force and movement. These parameters play a pivotal role in the functionality of the cylinder in its specific application. The bore size of a cylinder directly impacts the amount of force the cylinder can exert. A larger bore size allows greater force generation, making it particularly essential in heavy-duty applications where substantial force is required. This is due to the area of the piston being larger. According to the basic principle of Force = Pressure × Area, a larger area yields a higher force output for the same pressure.

Likewise, the stroke length of a cylinder determines the distance the piston can travel

from its fully retracted position to its fully extended position. Be sure to consider the space constraints of the system to avoid choosing a stroke length too long, which could lead to an inability to install the cylinder or

avoid complications such as insufficient force generation, which could render the cylinder ineffective for its intended use, or inadequate movement range, which could limit the functionality of the system.

CONSIDERATIONS

Of course, customization extends beyond size and material. The following factors can enhance the performance and integration of the cylinder with your system:

• Mounting Options: Different applications might require specific mounting configurations, such as flange, trunnion, or clevis mounts. Custom mounting guarantees ease of installation and optimal alignment with other system components.

• Seals and Bearings: The choice of seals and bearings affects the cylinder's performance, especially in high-pressure or high-temperature environments. Customizing these

components can enhance durability and reduce the risk of leaks or failures.

• Port Configurations: Custom port configurations can simplify hydraulic system plumbing, reducing potential leak points and optimizing fluid flow.

For Procurement Managers, aligning the ordering process with strategic goals is vital to ensure timely and cost-effective delivery. It’s vital to establish clear communication channels with manufacturers to share detailed specifications and timelines. Working with a reputable supplier can streamline this process.

FUTURE TRENDS IN HYDRAULIC SYSTEM DESIGN

The field of hydraulic systems is continuously evolving, with advancements aimed at improving efficiency, sustainability, and performance. Staying on top of these trends can help engineers and designers make informed decisions when ordering custom hydraulic cylinders.

• Smart Hydraulics: Integration of sensors and IoT technology in hydraulic

cylinders is becoming more prevalent. These smart cylinders can provide real-time performance data, helping during predictive maintenance and when reducing downtime.

• Eco-Friendly Materials: There's a growing emphasis on sustainable materials and manufacturing processes. Opting for eco-friendly materials without compromising performance is an emerging trend.

• Advanced Coatings: Coatings that enhance corrosion resistance and reduce friction are advancing, contributing to longer lasting and more efficient cylinders.

Ordering custom hydraulic cylinders requires a thorough understanding of specific application needs and factors that influence cylinder performance. By focusing on material selection, size, customization options, and aligning procurement strategies, it’s a guarantee that the custom cylinders chosen will optimize system reliability.•

Optimizing Vacuum Applications A FRESH PERSPECTIVE

By Daniel Pascoe, Davasol Inc

» VACUUM TECHNOLOGY, INCLUDING pneumatics and hydraulics, offers a wide range of component choices and system integration methods. Unlike its counterparts, vacuum technology has fewer component manufacturers and resources, making informed selection and integration more complex. As a result, end-users often depend heavily on the expertise of their local distributor or supplier’s sales representatives, who may only be experts on their own firm’s brands. Let’s explore alternative approaches and often-overlooked options for optimizing vacuum applications. The goal is to provide a more effective and cost-efficient solution for the vacuum end-user.

Rethinking Replacement Parts in Vacuum Applications

When users seek vacuum components, the most common request is for direct replacements of existing parts. While this approach is straightforward, it may not always be the best option. Consider the case of a manufacturer using silicone vacuum cups to handle molded plastic components at 49°C

(120°F). While silicone is a common choice, other materials such as nitrile rubber (NBR) may perform just as well, offering cost savings given that NBR is less costly.

Similarly, dimensional differences between suction cups can cause hesitation in switching suppliers. If a competitor’s cup is slightly longer, (Fig 1), the user should assess whether machine stroke adjustments can accommodate the new part. If the cup connection differs from the original (dimension F), replacing the cup fitting with the new supplier’s suction cup may be a viable solution using familiar threads, such as 3 mm or 6 mm (1/8 or 1/4NPT). This occurs often at a cost offset by long-term savings and improved supply chain options.

Evaluating Vacuum Venturi and Pumps

Beyond vacuum cups, selecting the right vacuum venturi or pump requires careful consideration. If a venturi requires replacement, the easiest choice is to find an exact match. However, this is not always optimal. Factors such as mounting configurations and vacuum flow capacity should be evaluated before settling on a replacement. For instance, an existing venturi with a 500 lpm (18 cfm) airflow may have been initially oversized for the application. The reasons for this are numerous but often a “That should do it!" attitude leads from the front.

A smaller unit might reduce compressed air consumption without sacrificing machine performance. In applications requiring extended vacuum hold times, integrating an energy-saving venturi automatically shuts off the compressed air supply when a stable vacuum level is reached. This can significantly lower operational costs. Fig 2 shows this energy savings kit setup installed on a vacuum generator.

Vacuum pump selection follows similar principles. Users often request the same pump specifications they have been using for years, without considering advances in pump technology. If an 8,500 lpm (300 cfm) centralized vacuum system was installed years ago, has the production environment

changed since then? A revaluation might reveal that a smaller, more efficient pump is now a better fit.

Addressing Vacuum Control Valves and System Efficiency

Vacuum control valves are another frequently misapplied component. Many systems use pneumatic valves instead of purpose-built vacuum ones, leading to suboptimal performance. Unlike hydraulics and pneumatics industry standards for consistent sizing and functionality, vacuum components vary significantly between manufacturers. This lack of standardization underscores the importance of selecting components based on actual application needs rather than simply replacing parts with identical specifications. For instance, a vacuum system using a 5,600 lpm (200 cfm) pump does not automatically require a 5,600 lpm (200 cfm) control valve. The key consideration should be the actual vacuum flow demand of the application, not just the pump’s capacity. Understanding the system’s cycle time and flow requirements allows for smarter valve selection, improving efficiency and reliability.

Conclusion: A Smarter Approach to Vacuum Component Selection

A well-informed approach to vacuum system design can yield significant benefits in cost savings, efficiency, and long-term performance. Rather than defaulting to direct replacements, Sales Engineers and Application Specialists should focus on understanding the broader application requirements. By exploring material alternatives, adjusting system configurations, and leveraging newer technologies, businesses can improve performance and lower operating costs. While reduced upfront costs may seem appealing, the true value of a well-optimized vacuum system lies in its long-term reliability and efficiency. By taking a proactive approach to component selection, fluid power professionals can provide their customers with solutions that enhance productivity and operational sustainability.

UNDERSTANDING THE APPLICATION OF ACCUMULATORS

Accumulator circuits store pressurized fluid. They are used for several purposes:

1. Maintain system pressure.

2. Absorb hydraulic shocks.

3. Supplement pump flow.

4. Provide auxiliary power.

5. Act as a barrier between dissimilar fluids.

Auxiliary power: One of the major benefits of using hydraulic accumulators is that they can store energy for later use. There are some functions that must occur, even if there is a power failure or if the

prime mover is not functional. Stored energy in an accumulator can be directed through manually operated, or DC solenoid operated valves to safely position equipment or isolate personnel from a dangerous environment. Some systems have a wide variation in loads or significant dwell time. The addition of an accumulator may allow the system designer to smooth out the power demand by providing an average flow to the system. When more flow is available than is required in a portion of the cycle, the extra volume is stored in an accumulator. When the required flow exceeds the pump flow, the accumulator will make-up the difference with the stored energy.•

TEST YOUR SKILLS

1 When servicing an accumulator and the hydraulic pressure gauge reads zero:

a. The gas may still have stored energy.

b. The nitrogen pressure will also be zero.

c. It is safe to remove the end cap.

d. Compressed air can be used to replace the nitrogen.

e. The bladder has ruptured and must be replaced.

See page 34 for the solution.

Safety tip: The accumulator must be completely discharged or blocked out of the circuit before attempting to disconnect any hydraulic lines. Never try to disassemble any

HYBRID ACTUATOR SYSTEMS HELP BRIDGE GAP FOR PLANTS WANTING THE ROBUSTNESS OF HYDRAULICS AND THE EFFICIENCY OF ELECTRIFICATION

By Bruce Besch, Alternative Motion Sales Manager, Parker Hannifin’s Cylinder and Accumulator Division

Traditional hydraulic systems have been the norm in most plants for decades. With the push to electrify and leverage greener solutions, machine builders have been exploring alternatives that combine these benefits. While it’s unlikely that manufacturing will be only electric, innovative hybrid options exist that are highly efficient, affordable, and robust.

THE HYDRAULIC APPROACH

There’s a reason that hydraulic systems have been around for so long. They represent a robust, reliable, and proven solution. They are controlled by a central power unit consisting of an induction motor, hydraulic pump, and valves to control direction, speed, and pressure. The fluid in the systems provides continuous lubrication and separates contaminants from moving parts, creating a self-cleaning, self-lubricating design. The fluid also provides dampening benefits to resist vibration and tolerate shock. The greatest benefit of hydraulics, however, is its power density. This is measured by its power-to-weight ratio. Traditional systems do have limitations. First, there are components in the system that must synchronize to achieve motion. When one component fails, it takes time to identify a failed component, and it takes the skill of an experienced hydraulics technician to fix the problem. In this era of many seasoned technicians retiring, responsibility often falls on less-experienced professionals who may not possess the knowledge needed to diagnose and remedy the problem. In addition, consolidated valve configurations in hydraulic systems create pressure loss, which consumes energy and creates heat, thus requiring the addition of a heat exchange. This makes for an inefficient design. Adding to the inefficiency is the fact that a central

hydraulic system must continuously operate, whether all functions are working or not.

Another serious concern is the potential for fluid leaks. Although hydraulics have a long-standing history of reliability, there remains the potential for fluid leaks. With numerous components requiring multiple connections, the risk of leaks is amplified. Additionally, the size of the system is another downside. Since it runs on centralized power, it requires a large motor, reservoir, and valving, taking up valuable machine space.

THE RISE OF ELECTROMECHANICAL ACTUATORS AND THEIR LIMITATIONS

Electromechanical solutions have been gaining ground in many applications due to their plug-and-play simplicity. Electromechanical actuators are typically fitted with permanent magnet alternating current (PMAC) motors. These motors have a high power-to-weight ratio and a high dynamic response. They allow for quick acceleration and can operate at a wide range of speeds, thus allowing for on-demand operation.

A screw drive is typically a ball screw or planetary roller screw with a lead that determines the travel per revolution. This serves as the prime mover. By controlling the screw speed (RPM), it’s possible to control the speed of the electromechanical actuator by varying the motor speed with a frequency converter. Since torque on the screw results in thrust, the same controller can limit amps to the motor. This restricts the motor torque passed to the screw, thus limiting the EMA thrust.

The motor runs only when power is needed, saving energy in comparison with traditional hydraulic solutions in which the motor runs continuously. Additionally, electromechanical solutions are generally quieter, and their

all-in-one modular design minimizes downtime since the entire actuator can be replaced for servicing. Despite these benefits, electromechanical actuators have a comparatively short service life and, on average, are three times the size of their hydraulic counterparts, which means more floor space. Because the systems are very rigid, they do not handle shock well. Any impact loading is passed from the nut to the screw, which means upsizing is required to handle any shock loading. Furthermore, they add a layer of complexity in programming, and cost per axis can be significant when compared to hydraulics.

THE PROMISE OF HYBRID ACTUATOR SYSTEMS

Given the shortfalls of both hydraulic and electromechanical systems, engineers have been focusing on ways to design a system that combines the benefits of both approaches without bringing along any inherent weaknesses. Doing so has opened the door to hybrid actuation systems that provide the desired speed and torque control with greater efficiency. This includes up to 80% energy savings and up to 90% space savings. Hybrid actuator systems are self-contained linear actuation systems that bring electrification and efficiency to where the work needs to be performed. This type of localized power optimizes energy consumption, increases machine performance, and reduces downtime. They look and feel like an electrical actuator yet have the power density and failsafe characteristics associated with traditional hydraulics. Hybrid actuator systems use many of the same concepts of an electromechanical system, but these systems turn a pump rather than turning a screw, using fluid transmission to move the actuator. With hybrid actuator solutions, the direction is controlled by changing the direction of the motor, speed is controlled by regulating the pump’s RPM, and thrust is managed by controlling motor torque.

The Hybrid Actuator System consolidates the entire hydraulic system into a single component integral to the actuator with all the controllability of electromechanical plus the fail-safe features and power density of a traditional hydraulic cylinder.

The result serves as an OEM machine design game-changer. This innovative approach allows engineers to strategically place actuators in locations previously deemed impractical or impossible due to electromechanical size constraints. Utilizing this method, designers can optimize machine layouts, enhancing performance and efficiency while reducing the overall footprint. This implementation of node-based hydraulics facilitates machine diagnostics and operational learning, which maximizes uptime. If maintenance is needed, the entire system can be replaced; this reduces downtime to only a few minutes. Additional advantages over a hydraulic and electromechanical approach include:

• Easier Maintenance: An all-in-one design creates a type of plug-and-play actuator that facilitates troubleshooting and is easy to install and set up.

• Superior Power in a Smaller Footprint: Since the actuator is hydraulic, it delivers three times the power density of a comparably sized electromechanical solution.

• Easy to Install and Control: Hybrid systems provide the desired control and accuracy without the use of valves.

• Energy Savings: This approach reduces pressure loss and significantly lowers wasteful energy consumption.

• Quieter Operation: Power On-Demand shortens the system's activation time, thereby reducing machine harmonics. Additionally, incorporating proportional control without relying on valves mitigates the "bang-bang" behavior commonly associated with traditional solenoid valves.

• Reduced Leak Points: A self-sealed design and fewer components means there are fewer potential leak points.

• Reduced Oil Reservoir Volumes: The size of these reservoirs is only a fraction of the size of those found in traditional hydraulic systems. These typically require less than a gallon of fluid.

• Longer Service Life: Environmental contamination is not a concern because of a sealed reservoir, which allows it to function in dirty environments. These systems offer up to 8,000 hours of maintenance-free operation.

• Greater Shock and Vibration Resistance: The fluid used is slightly compressible, so it can dampen any shock or vibration. This makes it ideal for heavy-duty applications that are too rugged for rigid electromechanical systems to handle.

• Superior Connectivity: The serial bus/ network is able to provide health and

performance feedback. The potential exists to monitor direction, speed, and thrust. Machine operating thresholds for scheduled maintenance and actuator replacement may also be assessed.

CONCLUSION

Hybrid actuation systems leverage the best of hydraulic and electromechanical solutions.

They are quickly gaining popularity in mobile and industrial applications that require the power, toughness, and resiliency of hydraulics in a smaller, smarter, and greener package. The improvements in safety and productivity made possible by advances in IoT connectivity are expected to transform numerous industries and operations dependent on linear motion.•

Localized Power vs Central Power

HYDRAULIC FITTINGS & HOSES

i n Agricultural, Heavy Construction, and Civil Engineering Industries

hydraulic systems rely on high-quality hoses and fittings to ensure that the fluid moves efficiently through the system, which is crucial when handling heavy loads. During harvesting, hydraulic hoses and fittings power mechanisms that help unload crops, adjust the cutting height, and rotate augers. Sprayers use hydraulic systems to control the boom arms that distribute pesticides, herbicides, and fertilizers. These systems need high-pressure hoses and fittings to deliver the necessary fluid at optimal flow rates, even under extreme pressure.

By Ryan O'Lone, Product Manager, PIRTEK USA

Hydraulic systems are integral to the operation of machinery and equipment across several industries, including agriculture, heavy construction, and civil engineering. Hydraulic fittings and hoses are essential components that facilitate the transfer of hydraulic fluid, which powers machines including tractors, excavators, bulldozers, and cranes. These systems rely on high-performance hoses and fittings to ensure safety, efficiency, and reliability in demanding environments. Below, we explore the role of hydraulic fittings and hoses in these industries, focusing on their types, functions, and maintenance requirements.

THE ROLE OF HYDRAULIC FITTINGS AND HOSES

At its core, a hydraulic system relies on the movement of fluids under pressure to perform work. Hydraulic hoses transport this fluid between different system components, while hydraulic fittings connect various hoses, pipes, and other components. These fittings and hoses are designed to withstand high pressure and extreme conditions, ensuring the machinery performs optimally. There are many factors to consider when choosing a hydraulic hose, including size and pressure rating. Still, it is important to consider other aspects such as the temperature ratings of the material the hose conveys and the ambient temperatures it will encounter. The hose’s resistance to

these temperatures plays a big part in the hose's life span, along with the minimum bend radius. If a hose is subjected to constant flexing while under pressure, then the makeup of the reinforcement used in the hose and its minimum bend radius must be considered to ensure a peak hose life span.

It's important to ensure that fittings are compatible with the size and type of hose used. There are published certified crimp specifications for assembling the fitting to the hose. It is also important to consider the hose’s use environment. While the most common type of hydraulic fitting is carbon steel with corrosion-resistant plating, it may be necessary to use stainless steel or another more corrosion-resistant material or plating type, depending on the environment in which the hose assembly will be used.

HYDRAULIC SYSTEMS IN AGRICULTURE

The agricultural industry relies heavily on hydraulic technology for equipment including tractors, harvesters, sprayers, and plows. The use of hydraulic systems in agriculture has greatly improved productivity by making machines more versatile and easier to operate. In agricultural machinery, hydraulic fittings and hoses help efficiently transfer fluid that powers key functions, such as lifting, steering, and controlling attachments.

Tractors are the backbone of modern agriculture. They use hydraulic systems to raise and lower implements like plows, seeders, and fertilizer spreaders. These

Agricultural hydraulic systems face unique challenges due to exposure to dirt, chemicals, and moisture, which can degrade hoses and fittings over time. These components must be resistant to wear and tear due to the harsh environments in which they operate. Regular inspection and maintenance are essential to prevent failures that can lead to costly downtime and decreased productivity.

HYDRAULIC SYSTEMS IN HEAVY CONSTRUCTION

Heavy construction equipment such as excavators, backhoes, bulldozers, and cranes depend on hydraulic systems for a wide range of functions, including lifting, digging, and moving materials. These machines work in demanding environments, often under extreme conditions, requiring hydraulic hoses and fittings that are both durable and reliable. Safety is paramount in heavy construction. Hydraulic hose failure can lead to sudden, catastrophic machine failure, posing a risk to operators and bystanders. Proper maintenance and using high-quality hoses and fittings are critical to ensuring safety and avoiding costly repairs.

Excavators and backhoes use hydraulic cylinders and motors to power the bucket, boom, and arm movements. These movements require high-pressure hydraulic fluid, and the hoses and fittings must be able to handle the force while maintaining fluid integrity. Hydraulic cranes and load lifters rely on hydraulic pumps and valves that control heavy loan hoisting and lowering. The hydraulic hoses must withstand the high-pressure fluid required to move tons of weight, while the fittings must maintain a secure seal to prevent leaks. Bulldozers and compactors utilize hydraulic systems to control blades and other attachments. As with other heavy machinery, hydraulic hoses and fittings must resist extreme pressures and harsh environments such as dust, dirt, and temperature fluctuations.

HYDRAULIC SYSTEMS IN CIVIL ENGINEERING

Civil engineering projects involve large-scale construction tasks, including road building, bridge construction, and underground utilities installation. Hydraulic systems play a vital role in these projects, with hydraulic machines used to move earth, pour concrete, and install infrastructure. Hydraulic pile drivers use powerful hydraulic systems to drive piles deep into the earth as part of foundation construction. The hoses and fittings used in these systems must endure high pressures and vibrations while maintaining their integrity over time.

Concrete pumps rely on hydraulic power to move concrete through pipelines to the construction site. These pumps require hydraulic hoses and fittings that can handle abrasive materials, high flow rates, and pressure extremes without leaking or bursting. In road construction, hydraulic systems control the movement and adjustment of rollers, pavers, and other heavy equipment. These systems often operate in harsh conditions, requiring durable hoses and fittings that are resistant to the elements.

Civil engineering projects also require robust hydraulic systems to handle the complexity and scale of construction. These projects often occur in challenging environments. As a result, the need for durable, high-quality hydraulic hoses and fittings cannot be overstated.

KEY CONSIDERATIONS FOR HYDRAULIC HOSES AND FITTINGS

In all of these industries, the performance of hydraulic systems depends heavily on the quality and design of the hoses and fittings. The following factors are critical in selecting the right components:

• Hydraulic systems in agricultural, construction, and civil engineering equipment are often exposed to high pressures. Therefore, the hoses and fittings must be rated to withstand these pressures without failure.

• Hydraulic systems in these industries can experience extreme temperatures, from freezing winter to scorching summer heat. Hydraulic hoses and fittings must be able to resist these temperature ranges without degrading.

• Equipment in these industries should be durable in rough environments, where dirt, debris, and chemicals can damage components. Hydraulic hoses and fittings must resist abrasion, corrosion, and chemical exposure.

• Hydraulic fittings come in various shapes and sizes. It’s essential to ensure that the

right fittings are chosen for the specific hydraulic system. Ill-sized fittings can lead to leaks or system failure.

• Hydraulic fluid leaks are a significant safety concern, as they can cause malfunctions or hazardous environmental spills. High-quality hydraulic hoses and fittings help ensure a secure and leak-free system.

MAINTENANCE AND INSPECTION

Regular maintenance and inspection of hydraulic systems are vital to extending the life of hoses and fittings. In all three industries, downtime due to hydraulic failure can result in significant operational delays and financial losses. Routine checks should include:

• Visual Inspections: Look for signs of wear, cracks, or leaks around hoses and fittings.

• Pressure Testing: Ensure that the hydraulic system is holding pressure correctly and that the hoses and fittings are not compromised.

• Cleaning: Equipment should be cleaned regularly to prevent the buildup of dirt and debris around hoses and other components, which can cause abrasion wear and build up, not allowing hoses to dissipate heat buildup.

• Replacement: Hoses and fittings that show signs of age and wear should be replaced immediately to avoid more extensive damage. Do not wait until a hydraulic hose has completely failed before replacing it.

CONCLUSION

Hydraulic fittings and hoses are fundamental to the operation of machinery in agriculture, heavy construction, and civil engineering. These components enable the efficient transfer of hydraulic fluid, ensuring equipment functions smoothly under tough conditions. Given the demanding nature of these industries, the quality of hydraulic hoses and fittings is paramount. Regular maintenance, proper selection, and timely replacement of worn-out parts are critical to ensuring the longevity and safety of hydraulic systems. By choosing the right components and maintaining them properly, operators can ensure that their machines ultimately contribute to the success of their operations.•

MASSIVE HYDRAULIC PRESS FASHIONS FITTINGS FOR MILITARY SHIPS

By Jason Palmer, PMP, CHPHS, Regional Sales & Applications, W&O Supply

Large military vessels require large diameter pipes and big fittings to move oil, steam, seawater, or anything else a ship might need. While conventional fittings have pressure ratings of 50 to 100 pounds per square inch (psi), these maritime fittings need to withstand pressures up to 6000 psi at diameters from 0.25 to 32 inches.

W&O Supply’s Seamless Marine Fittings Division is one of a few suppliers capable of meeting the stringent specifications for military applications. W&O Supply has over 45 years in the maritime industry, covering everything from repairing valves to supplying pipe, as well as retrofitting military and commercial vessels. The company has 18 branches dedicated to supporting marine construction, repair, and servicing on a global level.

In metalworking, a cold press is a machine tool that uses a non-heated die to shape or form metal blanks into desired shapes. It is a versatile and efficient technique used to produce a wide range of components, particularly those requiring precise dimensions

and intricate geometries. Cold presses shape fittings by bending them over a mandrel or through a closed die, which attaches to the central press’s ram. This results in stronger, more accurate fittings with greater consistency than is possible with hot presses, which can make the metal more brittle. In addition to producing better parts, cold presses also use less energy and produce less waste heat.

According to William Abbott, Director of Quality for W&O Supply, the U.S. Navy identified a supply chain weakness for such parts in 2017. There weren’t enough suppliers in the world making fittings in those size and tolerance ranges. The company sought to address the market need for such fittings; to do so, it needed a very large, highly accurate press. Such presses are not off-the-shelf purchases; each one must be custom-designed and manufactured.

W&O started small, with a 500-ton press able to handle fittings up to 10 inches as its first foray into this market. The design targeted high-strength materials and

difficult-to-manufacture items. Due to its fast success, W&O significantly scaled up its next iteration. The “full-size” four-post press handles 3,000 tons or six times the pressure of its predecessor. The total force contributed by all cylinders, each of which provides up to 1.2 kilotons of energy force, is 6,000 tons. Abbott notes its capacity to support the construction of military vessels including submarines, carriers, and destroyers. He also acknowledged that fittings in the commercial world would benefit from this product as well.

OVERCOMING THE MOTION CONTROL CHALLENGE

Precision motion control is critical for these presses. Erratic control ruins part quality and causes excessive press wear. William Abbott and W&O Supply have tried a range of motion controllers in their presses over the decades. Too often, Abbott notes that motion control solutions providers claim to have the capacity to fulfill all needs. However, limitations present themselves.

Abbott suspects the solutions were never intended to provide the necessary control, and the features won’t support it. Controllers exist that provide nearly hardware-level access to fundamental components, inputs, outputs, and ADCs. However, he states that many motion controllers are “black boxes you can’t see inside of.”

Abbott had seen controllers from Delta Motion used in other successful industrial applications and reached out to Delta to assess whether its system could handle the demands of W&O’s high-pressure cold press. Given the project required processes rarely seen in hydraulic presses, Abbott was initially skeptical but quickly recognized the potential of Delta’s RMCTools software. Noting the simple interface that provided W&O the

THE WRONG VALVE WOULD RUIN THE

ENTIRE PROJECT,

AS ABBOTT HAD DISCOVERED IN OTHER IMPLEMENTATIONS.

critical details, such as valve selection. Anything controlling velocity or pressure per the demands of this project had to respond accurately and consistently under high-pressure conditions. The wrong valve would ultimately ruin the entire project, as Abbott had discovered in other implementations.

SUCCESSFUL COMMISSIONING IN RECORD TIME

All in all, the Delta integration was seamless thanks in part to the quality of Delta’s PROFINET connectivity. Abbott notes that typically 1-2 weeks is allocated to get a motion control rack up and running. With Delta and the cold press, the team started on Monday morning, had the racks communicating by midday, and cylinders moving that night.

on industrial hydraulic motion control, with solutions from 1 axis to 50 axes, and motion loop times up to 8,000 times per second or 125 μs. Delta’s history of long-term support proved critical for presses that may be used and upgraded for half a century.

W&O Supply loved Delta RMCTools for its user-friendly interface and powerful features. Delta’s programming software provides the same powerful feature set needed to optimize performance, regardless of which controller was purchased. He was amazed to find that, whether a company opts for the least or most expensive controller in Delta's lineup, RMCTools is included at no additional cost. He also admired Delta’s “old-school” approach to service—referring to Delta Motion’s emphasis on knowledgeable

access needed to fulfill a number of functions, it became very clear to Abbott that the product fulfilled all of the company’s needs.

W&O selected a Delta RMC200 motion controller equipped with an SSI interface and high-resolution analog modules, along with two digital channels. The modules were highly configurable and prevented W&O from purchasing special modules for specific widgets. Abbott happily noted W&O’s ability to now utilize SSI and analog feedback for position and velocity. He also acknowledged Delta’s distinctive, rare level of expertise pertinent to different kinds of motion.

Abbott collaborated with his hydraulic designers and Delta’s engineering team on

Integration was completed in a single day. Similarly, the normal time required for tuning the motion axes on an installation would have been a week. With Delta, it was only one more day. Abbott contrasted this experience with the 500-ton press W&O had developed earlier using a motion control system from another supplier. It didn’t work as well over four years versus what the company accomplished in two days with Delta.

BUILDING FOR THE FUTURE

Delta's RMC200 can control up to 50 axes, surpassing the application's current needs of 5 axes. Abbott had scalability in mind from the outset. W&O Supply appreciated Delta’s focus

and responsive technical support. Abbott notes that all Delta personnel were wellversed in their areas of expertise, which he attributes to a high caliber of training, paired with customer needs acumen.

Previously, W&O worked with a vendor that recently entered into the motion control arena and expressed confidence in its ability to meet W&O’s needs. After 4 years, Abbott states that the vendor’s solution does not work as well as what the company achieved in 2 days with Delta. Since commissioning this application, W&O has experienced zero failures and needs to make zero adjustments. The motion system has constantly operated since its inception and continues to perform flawlessly.•

» HERE IS THE SOLUTION TO FIGURE IT OUT ON PAGE 05

When they installed a new flow control, the customer needed to replumb the external pilot line on the counterbalance valve between the new flow control and the cylinder’s cap end. The counterbalance function is focused on the cap end pressure. If it starts to drop, the counterbalance closes off just enough to keep the cylinder from speeding up faster than the meter-in flow control requires.
