Electronic Software Won’t Program Out Bad Hydraulics

By Lisa DeBenedetto, Account Manager, GS Global Resources

»

WHEN LOOKING AT machine design, there are several major engineered systems that need to be considered and are intertwined at every turn. To name a few: hydraulics, electronics, mechanical, safety, efficiency, regulations, performance, comfort, and cost. I am sure there are others, but you get the point. Many times, smaller OEMs have excellent engineers on staff, but they have few or no hydraulic experts. In my career, moving from the factory representative side to the system integrator/distributor side, this revelation has never been clearer. The challenge is convincing the “we have always done it this way” crowd that an electronic control system update may require a hydraulic or mechanical system update as well.

Have you ever been asked to add or update an electronic control scheme on a system? This seems straightforward. But once you look at the hydraulics and mechanics of the system, it becomes obvious that updating or converting to an electronics scheme will not address the mechanical and hydraulic shortfalls of the system.

Here are things to look for that indicate you need an update in the hydraulics or mechanics instead of adding to or improving the electronic controls.

1.Double or triple gear pumps. In some systems this might be necessary, but hydraulic integrated circuit (HIC) manifold technology might be a better alternative. It’s possible a single pump in conjunction with a priority on demand and a flow-sharing circuit in a custom HIC could improve performance and efficiency while reducing heat. The cost of custom HICs in low quantities has dropped enough to make it a viable option for machine improvements. Machine controllers and electronics are designed to work well with on/off and proportional valves.

2. Double or triple coolers. Depending on the machine this might also be necessary but is potentially a sign that improvements can be made. If the system has a heat problem, adding electronics probably won’t help reduce the heat, but it could certainly tell you the system is hot. If the system has two hydraulic tanks, then two coolers might be necessary. Systems with two tanks usually have one tank specifically for the closed loop portion and a second for the auxiliary functions, which helps maintain cleanliness and cooling where needed.

3. Single-acting cylinders. Generally, these are used because of their lower cost to double-acting cylinders. However, load holding, gravity down, safety, and load drop are all issues where electronic programming can only go so far.

4. Low-speed high-torque motors in creep mode. As we all know, there is low speed and then there is a creep speed. Efficiencies vary in 4

the different types of low-speed high-torque motors. But try operating one well below the manufacturer’s specified speed, and you get torque ripple and speed fluctuations you cannot program out with software.

5. Stalling the engine. There is usually one main reason the engine stalls: you are drawing more horsepower than the engine has available. Looking at the workload requirements and recalculating system demands is one way to find overall hydraulic system improvements. Revamping the electronics might help shift or control where the horsepower is being used, but it cannot circumvent the laws of physics and miraculously create more horsepower.

6. Safety. If the operator needs to stand up or move into harms’ way to operate the machine, creating a radio remote or pendant control system could address these issues.

Although radio remote control systems have improved significantly in their robustness, the cost might still be an issue. A cost analysis needs to compare the mechanical and hydraulic safety changes versus the expense of a radio remote.

7. Contamination. If the system is designed where the hydraulic filter elements cannot be changed, new electronic controls will not address the problems.

I am sure there are many other examples. The bottom line is that machine design is complex and trying to improve one aspect (electronic control system) without looking at the others is not a recommended practice.

OEMs of any size can take several actions to update their equipment and machines with new or updated electronic control systems. Invest in your employees. There are several community colleges offering hydraulic, electronic, or mechatronic classes. These programs offer associate degrees. Require your mechanical engineers and electronic engineers to be certified in fluid power or hydraulics specifically. Work with your local system integrators who generally have mechanical, hydraulic, and electrical engineers on staff already. The system integrators also have years of experience on a variety of machines and equipment to draw from.

Whatever the needs for machine updates or improvements, it is critical to look at all aspects of the machine working together and find a fluid power professional who can help. Or better yet, create your own fluid power champion within your organization. To find support with your machine improvements or with training your staff, start with the International Fluid Power Society or the National Fluid Power Association. •

Sizing Vacuum Components

By Dane Spivak, Engineering Manager, Davasol Inc.

The design principles of most fluid power systems and vacuum gripping system by pulling it out faster and reaching a higher vacuum level as a result. systems are governed by flow rate and pressure. There are numerous potential However, that requires an increase in pump cost, energy consumption, and solutions for applications, though an ideal design would consist of efficient overall system size to handle larger flows. For those costly reasons, increasing energy use and low project and maintenance costs. This article highlights the pump size should only be done if necessary. Therefore, finding the right the strategic thinking of sizing vacuum gripping components based on the cup and tool for the application is crucial to the bigger picture; it determines the required parts for the rest of the system. Comparably, you would never aforementioned notions.

To begin, let’s analyze vacuum cup sizing and how it affects other areas use a crane to lift a small brick. Perhaps this is an exaggerated analogy, but of the system. When gripping a smooth surface where a cup can seal “per- it paints a similar picture.

Vacuum pump selection and sizing go hand in hand with the vacuum fectly,” such as glass or sheet metal, the maximum vacuum level is easily cups; they both depend on one another. If we revisit the concept of gripping achieved as there is no leakage. This makes for easy sizing of the vacuum smooth parts such as glass or sheet metal, the flow of the vacuum pump cups because you can calculate the gripping force using the cup diameter would be of interest. Since this would essentially be considered a closed and final vacuum level reading. After considering the safety factor, you can system, the vacuum pump will reach near its maximum vacuum level so the determine the vacuum cup accurately. Using cups smaller than the target flow will determine how quickly it gets there. Typically, these systems would size results in an unsafe or incapable system, and anything larger is unnecrequire relatively small and lower flowing pumps unless the cycle rates are essary overkill and additional cost. very fast.

If the volume of the system is known, you can make theoretical When considering gripping a product surface that is uneven or porous, calculations to estimate the evacuation time to reach certain vacuum levels. such as a cardboard box, bags, or packaged food, suction cup sizing becomes more tactical. Due to the nature of the product surface, cups are unable to create a perfect seal. Air leaks between the cup and product surface and Test Flow 1 cfm 2 cfm 5 cfm 8 cfm 10 cfm 15 cfm gets sucked into the vacuum Vacuum Level 0”Hg 3”Hg 12”Hg 24”Hg 25”Hg 25”Hg system, as shown in figure 1. This is what is known as Flow and vacuum level data from testing with a target of 24”Hg. leakage, which reduces the vacuum level pressure and gripping force. This is an The table above shows sample data collected from a vacuum gripping test exaggerated example where in which the target vacuum level is 24”Hg. At 1 cfm the vacuum level reading the leakage gap is clearly vis- is zero, which means the pump is unable to produce a vacuum level because ible, though often the gaps are there is more leakage entering into the system, and it cannot pump out very small but also extremely enough air to quickly create a pressure differential. As we move up to 2 cfm impactful to the final vacuum and 5 cfm, we see the vacuum level start to climb. At 8 cfm the target of 24”Hg Figure 1 level.

Air leaks into the vacuum system due is met, which, based on this data, would be the minimum requirements. If to a gap in the vacuum cup seal.

Reducing leakage as best as the system is small, simple, and reliable, the 8 cfm pump would be a good possible in a gripping system choice. The reading of 25”Hg at 10 cfm is a touch higher in performance than is usually ideal, as it produces higher vacuum levels and gripping forces. You needed but is also an attractive choice if the system has potential losses or should first select the right style and material of cup to grip the product, but the pump might lose performance over time. Lastly, the 15 cfm appears to then sizing the right diameter is a close second. A common trend with vacuum offer no benefit; it is nearly double the flow than required and too much of a cups is that larger diameter cups have thicker lips that do not seal as well on safety buffer offering little to no returns.

crane analogy, this would be similar to deliberately using a crane to pick up a small brick simply because you know it will work. Luckily, some pump model performances are adjustable using techniques such as regulating the compressed air pressure on air powered venturi generators, using variable frequency drives, relief valves, or other external adjustable devices. These can help save energy if the pump is unnecessarily overworked, or, on the other hand, it can help increase flow and vacuum level if a pump is undersized. Approval from the pump manufacturer should be confirmed before proceeding with such changes.

We have discussed the importance of sizing cups and pumps. We are left with everything in between, which includes parts such as fittings, hose, valves, and filters. The parts themselves have their own purpose. But from a sizing standpoint they all follow the same rule, that golden rule being sizing each part to have the ability to allow air to flow through the system effectively to minimize losses or restrictions between the pump and the cups. In a few words, flow rating is most important. If components are oversized, the system will have too much volume, which would take more time to pump out air and reach desired vacuum levels. Not to mention the additional costs involved.

If the components are undersized, the system flow is restricted and cannot breathe freely. This would mean the pump is unable feed the vacuum cups its maximum potential performance and would be consuming excessive energy. A vacuum system is only as strong as its weakest point. If there is one part in line with the system flow that is undersized, it affects the rest.

Figure 3 shows a system with an undersized valve. The pump is producing 50 cfm, while the valve is only capable of handling 20 cfm. Therefore, 30 cfm of performance is lost since the valve is restricting the potential flow produced by the pump, which prevents the cups from accessing the complete

WWW.IFPS.ORG • WWW.FLUIDPOWERJOURNAL.COM

available flow. Back to the crane example, if the crane has a strong base and lifting device capable of handling heavy loads, but the beams cannot handle nearly as much, it becomes ineffective because the beams prevent the base and lifting device from carrying their maximum potential weights.

A solution to the vacuum valve restriction would be to use a 50 cfm+ valve or perhaps use three 20 cfm valves in parallel, which would equate to 60 cfm.

Flow and vacuum level are the key performance factors in vacuum gripping systems.

The sizing of each component can affect these factors in applications, so strategic selection is critical to the final design.

Each application presents a new set of challenges, Figure 3. Schematic of a vacuum system in which a and professional valve restricts flow to the cups. advice is recommended for the right solution. • This article is the opinion of the author, Dane Spivak of Davasol Inc., an industrial brand management firm.

Electrohydraulics On the Road to Zero

By Miguel Onandia, Electro-Mobility & Services Sales Manager, Poclain

T

he off-highway equipment market is undergoing a strong zero-emission trend in line with increasing regulatory, political, environmental, and societal pressure at local and global levels. This trend will accelerate in the upcoming decades on all continents. The small off-road machinery segment will be particularly impacted in terms of penetration. It is comprised of machines with a total power lower than 19 kW, with two-, three-, or four-wheel drive configurations and with traction and auxiliary functions. These include, for example, mini-wheel loaders, mini-site dumpers, truck-mounted forklifts, or light tandem compactors.

On the end-user side, the needs related to small machines are going to evolve to include: • zero emissions on-site, • low noise pollution for both operator and on-site, • the same performance as machines with internal combustion engines, • sufficient operational range in hours per day, • increased safety to use and maintain, and • improved total cost of ownership compared to machines with internal combustion engines.

To address these evolutions in the small-machinery segment, machine manufacturers are developing and producing more emission-free machines. Versions with internal combustion engines will cohabit with versions without an engine in assembly factories, either sharing the same machine platform (the current one with internal combustion engine) or using dedicated ones. The breakdown of numbers between all versions will vary over time, depending on applications, markets, and internal factors. This evolving market situation requires versatile development strategies for the machine manufacturers.

When developing zero-emission off-road equipment, various technologies are possible for consideration. This article considers and evaluates three technologies: electrified axle (e-axle), electrohydraulic with hydraulic wheel motors, and electric wheel motors (e-wheel). The decision for one solution or another can have a global impact on the purchasing, supply chain, R&D, industrialization, sales, aftermarket, and finance at machine manufacturers.

In terms of the components, e-axle and e-wheel technologies require multiple inverters and electric motors, while the electrohydraulic solution can use either single or multiple inverters and electric motors. In both

engine and a hydrostatic transmission, the electrification technology that logically comes to mind first is the electrohydraulic one as particularly well suited to electrify these machines.

With electrohydraulic technology, different architectures are possible. Among them, we have: • Architectures with two separate electric motors, one for the propel function with a closed loop fixed displacement pump and the other for auxiliary functions with open loop pump. These architectures are used if the duty cycle and sizing show benefit in performance and efficiency.

• Architectures with one single electric motor, used for both

the propel function with a closed loop variable displacement pump and auxiliary function with an open loop pump. These architectures are used if cost and commonality with the diesel version of the machine matter more.

cases, a strong knowledge base in inverter design, manufacturing, and embedded control software are key.

If we consider current machines fitted with an internal combustion 10

Electrohydraulic transmissions provide a variable ratio, thanks to their multi-displacement hydraulic wheel motors and possibly their variable displacement pump. Moreover, electrohydraulics provides benefits in terms of control: the propel function uses a closed loop hydrostatic circuit allowing four-quadrant operation, regeneration while braking or driving downhill allows for range improvement, smart control and proper sizing allows for transmission optimization. Concerning safety, either in conditions of state of charge close to 100% or in conditions of negative cell temperatures, braking can be secured thanks to hydrostatic braking and emergency friction brakes available with electrohydraulic technology.

On the OEM side, no complete machine redesign is needed because mobile hydraulics remains and is combined with power electronics and a battery. This means that the electric machine development costs are lower because the project perimeters are smaller. In addition, the industrial investments are lower as well because the impact of electrification on the current assembly lines is smaller. Concerning the procurement flows and stocks, they are simplified by the high commonality of components between current diesel and new electrohydraulic machines. Therefore, electrohydraulic technology provides both cost efficiency and a shorter time to market than is usually possible for zero-emission machines.

On the machine users’ and owners’ side, electrohydraulic technology provides a series of benefits as well. Among others, users and owners include machine rental companies, construction, agricultural and industrial companies, and many others. The first benefit of electrohydraulics is the time-proven high ruggedness coming from its hydraulic core. Actually, mobile hydraulics has equipped off-road machines for decades and has acquired a high level of maturity over time. In a quickly evolving environment, high ruggedness and maturity are valuable for OEMs as well as for machine users and owners. Moreover, keeping the current mobile hydraulics allows them to achieve the same performance with the electrified machine as with the current diesel one. This advantage is key because a given machine must achieve a certain amount of work regardless of its energy source to ensure the required productivity and solve the economical equation.

If we look at the machine level, the comparative evaluation of the electrification technologies has to take into account various criteria simultaneously, including: •M achine integration. The physical installation of the system on the machine (for example, the available space, ease of installation) and the contribution of the system to the machine control (for example, ergonomics, controls).

• Performance. What the machine does (for example, speed, load capacity, traction control).

• Range. Factors that impact the machine range in hours (for example, battery size, compromise between efficiency, and duty cycle).

• Noise. The noise level emitted by the machine (for example, hydraulics, gears).

WWW.IFPS.ORG • WWW.FLUIDPOWERJOURNAL.COM

•S afety. The safety of people who will interact with the machine in one way or another (for example, high voltage or current, battery regeneration limits).

•C ost. All costs related to the system lifecycle (for example, production, recycling).

A FRIEND INDEED

Hydraulic Fluid That’s Safe for the Planet

By Benjamin Garmier, Vice President, Renewable Lubricants Inc.

A

s companies develop alternates to traditional lubes and greases, there is often confusion about the terms “environmentally friendly” and “food grade.” Formulations that meet the criteria for one don’t necessarily hit all the notes for the other. The Environmental Protection Agency defines EAL – environmentally acceptable lubricants –according to three criteria: biodegradability, toxicity to marine and aquatic life, and bioaccumulation. This article looks at how Renewable Lubricants’ Bio-Food Grade Hydraulic Fluid is both environmentally friendly and food grade.

Food grade According to the National Sanitation Foundation, to be registered as a lubricant that allows for incidental food contact, the product must be odorless, colorless, and tasteless. It must not contain more than 10 parts per million of lubrication base oils (for example, mineral oil), and it must be registered as H1 or certified to ISO 21469. Additionally, it must be manufactured from ingredients, chemical compounds, or additives allowed by the FDA’s Code of Federal Regulations Title 21, Section 178.3570. Or it must be manufactured from ingredients designated GRAS – generally recognized as safe.

Feedstocks Feedstock – the materials from which the lubricant is made – plays a big part in determining whether a hydraulic fluid meets the EAL standard. Biobased products, especially those made from vegetable oils, are inherently safer for the environment than petroleum-based products, which is just one reason for their increasing popularity. Formulations that use food-grade edible oils along with vegetable-based oils that are further processed into a biosynthetic to enhance their lubricity and protective properties are not only safer for the environment than petroleum-based products, they are also safer for employees. Petroleum-based products can be caustic and harmful in contact with skin, whereas biobased products generally pose no problems with incidental skin contact.

Renewable Lubricants has developed a proprietary and patented technology using high oleic base stocks (HOBS), which are 18

SEPTEMBER 2022

agricultural biobased oils. Incorporating the super high viscosity index of the Stabilized HOBS into the formula increases the viscosity past synthetic levels. The super high viscosity index of HOBS naturally improves the thermal shear stability of the formula and increases load capacity. The low volatility of HOBS increases the flash and fires safety feature of the formula, making it safer for employees.

These patented biobased hydraulic fluids are formulated to perform in high- and low-pressure hydraulic systems that require anti-wear, antirust, anti-oxidation, anti-foam, and demulsibility properties. They provide improved performance in oxidation stability over standard plant/vegetable/HETG and unsaturated HEES type fluids. Formulated to provide a longer seal life with reduced oil leakage, Bio-Food Grade Hydraulic Fluid meets or exceeds high-pressure pump requirements.

The fluid is highly inhibited against moisture and rusting in both fresh and sea water, and it passes A and B sequences of the ASTM D-665 turbine oil rust test. Formulated to provide a longer seal life with reduced oil leakage, the zinc-free product is ideal for vane, piston, and gear-type pumps. It has shown excellent anti-wear performance in the ASTM D-4172 four-ball wear test. The anti-wear performance meets and exceeds requirements for Vickers M-2950-S (35VQ-25) and I-286-S (V-104C), Rexroth, U.S. Steel 126, 136, and 127, and DIN51524 Part 2. The fluid also meets the requirements for ashless GL-1 an GL-2 gear oils in reduction units and gear sets where EP gear oils are not recommended.

To ensure performance and long life, Renewable Lubricants developed the stringent IsoGreen filtration standard, which meets or exceeds the Rexroth pump guidelines for hydraulic fluids.

WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

Biodegradable Biodegradability is broken down into two classes – readily biodegradable and inherently biodegradable – based on how much of the product breaks down within a set timeframe.

Readily biodegradable products break down by 60% or more within a 28-day period. If they do not meet this criterion, if they fall, for example, between 20% and 59% within 28 days, then they are classified as inherently biodegradable.

Most industrial applications strive for readily biodegradable products, but the classifications are not well understood or explained. Some products that are inherently biodegradable are merely marked “biodegradable” without explanation. When in doubt, ask for the details from the manufacturer or distribution channel partner before specifying a product based on its biodegradability. Bio-Food Grade Hydraulic Fluid is readily biodegradable.

In addition to use on food processing equipment, Bio-Food Grade Hydraulic Fluid is ideal for use in environmentally sensitive areas such as marine environments, aboard fishing vessels, and in agriculture, especially in harvesting of grains as well as working in and around fruit farms and processing facilities.

Bioaccumulation Bioaccumulation is the buildup of foreign chemicals within the tissues of living organisms over time. Heavy metals like zinc, cadmium,

and others either do not break down or do so very slowly. When they enter a water source, they are ingested by smaller fish, which are food sources for larger fish, until the fish become food sources for humans.

Renewable Lubricants products are formulated with no zinc or other heavy metals, so there are no bioaccumulation worries. They are also free of volatile organic compounds, so they are safe for workers and the environment. Made from renewable agricultural biobased resources, they are sustainable as well. •

Toxicity The EPA and the U.S. Fish and Wildlife Service base toxicity on how much of a chemical (with concentrations measured in parts per million) is present before it becomes harmful to plants (algae) and fish. There are different values for each. For acute toxicity for algae, EC50 in the concentration of test substance that results in a 50% reduction in either growth or growth rate relative to the control within 72-hours of exposure. The acute toxicity of fish is expressed as the median lethal concentration (LC50), which is the concentration in water that kills 50% of a test batch of fish within 96 hours of continuous exposure. Bio-Food Grade Hydraulic Fluid exceeds the acute toxicity levels (LC50/EC50 > 1,000 ppm) adopted by the U.S. Fish and Wildlife Service and the EPA. With oxidation performance (biodegradability and toxicity) comparable to full synthetics, this is one of the safest hydraulic fluids for the environment and the only one that is food grade.

This graph of raw index data is generated by the total dollar volume reported to NFPA by CSS participants and compared to the average monthly dollar volume in 2018. For example, the June 2022 total dollar volume for pneumatic shipments is 117.2% of the average monthly dollar volume in 2018. (Base Year 2018 = 100)

The table above is expressed in terms of cumulative percent changes. These changes refer to the percent difference between the relevant cumulative total for 2022 and the total for the same months in 2021. For example, June 2022 pneumatic shipments figure of 7.6 means that for the calendar year through June 2022, pneumatic shipments increased 7.6% compared to the same time-period in 2021.

Pneumatic, Mobile and Industrial Hydraulic Orders 12/12 Ratio Each point on this graph represents the most recent 12 months of orders compared to the previous 12 months of orders. Each point can be read as a percentage. For example, 131.1 (the June 2022 level of the industrial hydraulic series) indicates that industrial hydraulic orders received from July 2021 to June 2022 were 131.1% of the orders received from July 2020 to June 2021. (Base Year 2018 = 100)

Total ‐ Hydraulic and Pneumatic Shipments 12 Month Moving Average

TEST YOUR SKILLS

Considering Component Compatibility S

ome fluids with very good lubricity and viscosity characteristics may prove caustic to the material in pumps, actuators, or valves, especially when hot.

There are three areas of component compatibility that the designer needs to consider. The first is within the circuit, the second is chemical reaction, and the third is temperature.

Chemical compatibility is an important consideration when choosing the hydraulic fluid for the system. The inner tube of the hydraulic hose must not react chemically with the fluid. The same can be said of the seals within the components. Water is a chemical that can adversely affect the seals, so special seals must be applied where high water-content fluid is used. Water-glycol fluids attack zinc, cadmium, and aluminum, so these elements must not be located anywhere in the circuit in order to prevent contamination and deterioration of the hydraulic system. It is important that the designer be aware of the composition of the parts that make up the system components.

-65°F to 300°F -54°C to 149°C

4. Nitrile rubber (Buna N)

Petroleum base fluids and mineral oils – used for some rotating seals, extrusion resistant

-65°F to 225°F -54°C to 107°C

5. Silicone rubber

Water and petroleum base fluids, phosphate esters; low tensile strength and tear resistance recommended for static seals only

-80°F to 450°F -62°C to 232°C

6. FluoroElastomers (Viton and Fluorel)

Petroleum base, synthetic, diester, silicate ester, and halogenated hydrocarbon fluids – for high-temperature fluid applications

-20°F to 400°F -29°C to 204°C

Many seals are manufactured in a process that includes heat to cure the product in the mold. This process is very specific and provides the Duron rating of the seal. Exposing seals to heat beyond their rating will result in continued curing, making the seals brittle and without proper elasticity.

The designer must be familiar with the chemical and temperature compatibility charts for both seals and metal parts (see chart) so that proper choices can be made.

Seals prevent internal and external leakage in a hydraulic system.

Static seals are used for pump housings, valve bodies, and reservoir covers, and between cylinder ends and the cylinder tube, where there is no relative movement between the parts to be sealed. Dynamic seals are used between moving parts, for example, between the piston and cylinder bore, and between the cylinder rod and the rod bearing. About 80% of seal applications use static seals.

The starting and operating temperatures of the machine are also used to select hydraulic seals that retain their sealing properties in ambient and hot conditions. Neoprene, a general-use sealing material, has a temperature range of -65°F to 225°F (-54°C to 149°C). Neoprene is satisfactory for static gasket seals and O-rings with petroleum base fluids, but is not as well suited as Nitrile rubber (Buna N), urethane, and even leather, for dynamic applications. Extremely cold and hot conditions require a sealing material that is more tolerant of heat. Viton and silicone compounds are the sealing material of choice for applications with temperature extremes.

The ability of a sealing material to prevent leakage is tested by measuring the durometer (indentation hardness), creep, and compression set after deformation. The sealing compound must be hard enough to resist wear and extrusion for the clearance gap and pressure that will be encountered, yet still be soft enough to maintain a seal during continued use. Seals have a tendency to swell in the presence of hydraulic fluid. Some swelling is permissible, and even somewhat desirable, in maintaining a fluid-tight seal. But excessive swelling and accompanying softness of dynamic seals increases friction and the tendency to abrade. Twenty percent swelling is considered the maximum allowable swell; swelling by a factor of 40% to 50% is allowable for confined static seals. •

By focusing on these inputs, tests can be designed to understand a seal’s capability. For example, such testing may reveal that a seal performs well at higher pressure limits only when the speed is maintained at a slower velocity. It may also find that a seal performs well at a higher temperature when the appropriate viscosity fluid is used to assure proper lubricity at the sealing lip. All this data provides a clearer picture of the strengths and weaknesses of a seal, making the selection of a seal package much easier and the life expectancy of that package much clearer.

Hallite has invested in expanding its test capabilities at the company’s Hampton, U.K., facility and in partnership with the Milwaukee School of Engineering and OEMs. As a result, durable test equipment has been designed to replicate application conditions consistently. We will consider findings from three critical areas: surface finish, oil viscosity, and seal lip temperature using infrared technology.

Surface finish. Testing revealed how exposure to various conditions impacts a seal's performance and overall life. An example is the dynamic hardware's surface finish impact on seal function and life. Testing confirms that all surface finish factors must be considered to ensure the best seal life and performance.

Ra was considered the essential factor in the past, with little or no consideration given to Rz or RMR (see figure 2). Extensive testing has shown that having an Ra that is considered acceptable with an Rz that is above the recommended level will impact overall seal performance. Running seals on surfaces with a low Ra (too smooth) will cause the seal not to perform as expected. Smoother surface finishes would have both a low Ra and low Rz, which, in theory, should enhance seal life as the surface is not rough and causes micro tearing at the sealing lip. However, having a dynamic surface that is too smooth does not allow proper boundary lubrication to get to the sealing lip, causing it to overheat, resulting in premature wear. Testing has quantified how both conditions (e.g., surface finish too rough or too smooth) impact the seal's performance.

Oil viscosity. Hallite testing has also revealed that using the proper viscosity oil may significantly impact seal life. Most of the seal testing (piston and rod seals) occurs at either 185°F or 212°F (85°C or 100°C) fluid temperature using an ISO 46 oil. A set of tests revealed that a seal performed well at 185°F (85°C) but less effectively at 212°F (100°C). As an experiment, the oil was changed to an ISO 220, which maintains a much higher viscosity level at higher temperatures. The test revealed that the seals that did not perform well previously at 212°F (100°C) were now able to seal effectively at this temperature. It was concluded that the media or fluid provided proper lubricity, which kept the sealing lip from overheating during the test (see figure 3).

Seal lip temperature. Understanding the effectiveness of media in providing proper lubrication led to other questions on mapping temperatures of the seal in operation. Both rod and piston seals have a minimal

eals play a vital role in fluid power because they allow for the containment of pressurized fluid, which produces the energy for various pieces of equipment. The premise of fluid power is based on creating this energy and involves managing or controlling it for maximum effectiveness in a wide range of applications. Therefore, understanding the demands of each application is essential to offering the best sealing solutions to keep equipment operating efficiently for as long as possible.

Seal experts make recommendations based on where the seals will be used and their knowledge of overall field performance (both good and bad) with specific seal packages. Because of the wide range of applications and ways equipment might be used, replicating field operating conditions in a test environment is complex. Though some of these conditions may be simulated, the challenge is rapidly changing the conditions during the test cycle. Having test equipment capable of making these changes is possible, but the cost of the advanced control systems and fixturing to handle millions of testing cycles is significant.

Nevertheless, advances in control system technology combined with the use of some creative test fixture designs make performing these tests a reality.

So why is the testing of seals so important?

Understanding how seals perform in a wide range of conditions allows the seal manufacturer to make and recommend better seals based on performance data. Five inputs determine how a seal will perform: size, temperature, application, media, pressure, and speed, often referred to as STAMPS (see figure 1).

Understanding of the size of the dynamic hardware that needs to be sealed and the length or “L1” of the groove available for the seal – Ratio to assure proper “squeeze” and seal placement in the system.

Understanding of both the media and environmental temperatures the seal will be exposed to in the application.

This includes both the highest and lowest potential temperatures.

Application where the seal will be used or any specific differences as compared to what might be seen in these applications (e.g., higher the anticipated operating conditions).

Understanding the media that is being sealed is key to making sure the proper material is used in the design.

Media also plays a part in determining the proper seal material to ensure long seal life.

Understanding both maximum operating pressure and potential pressure spikes is key to choosing the proper seal configuration.

Knowledge of low-pressure sealing requirements is also important to establish the operating range.

Speed of travel is key to ensure excess seal friction is avoided resulting in premature failure.

Consideration of slower speeds is also important as slow and long stroke applications offer additional challenges to sealing.

contact point to the dynamic surface that is referred to as the sealing lip. Because this area is so small, the testing team postulated there would be a noticeable temperature difference compared to the temperature of the media, but they had no idea what that would be. Rotary fluid power seals typically present a difference of 80-90°F (27-32°C), which can be measured as the shaft rotates.

Since the test focused on hydraulic cylinder seals, the team had to find a way to install sensing equipment on or near the sealing lip, which was difficult. Working with MSOE, a state-of-theart test method was developed using infrared technology to measure sealing lip temperature.

Using a rod seal, the test methodology mapped out temperatures of the media, rod, and sealing lip of the rod seal to assess the frictional heat generated at that location. As a result, the industry now has a platform to understand better how oil viscosity impacts sealing lip temperature, providing the expertise to recommend the optimum seal solution, minimizing heat and frictional wear. •

FIGURE IT OUT

Extractor Motor Reverse Speed Rises to an Unexpected Creep

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

»

A HYDRAULIC SYSTEM drives a vertical ball screw that slowly lowers product into a vat. The company found it was important that the force of lowering the part be limited in case the new part encounters a previous part that had not moved out of the way. They installed a pressure-reducing valve to control the lowering force, and it worked well.

They experienced a leak coming from one of the swash-plate bearing covers and replaced the pump with a new one they had in stock. They primed the pump and set the pressure, ran several cycles, and turned the machine over to production.

Production called maintenance back to the machine complaining about a problem with the reversing speed of the hydraulic motor. Every two or three cycles, the motor would act like it had a flow control adjusted to low speed when the motor reversed. After inspecting for a contaminate in the lines and inspecting the pressure reducer and directional valve, they could not find the problem.

What could be the issue?

Solution to the August 2022 problem:

Deep Pan Forming Press Loses Operating Pressure

The 200-ton press pressure problem was a hard one to solve. It was determined that the lack of filtration had introduced scarring on the solenoid #6 directional control valve spool, increasing its leakage to tank when pressure is present. The only oil flow leaving the X port (sometimes referred to as the vent) of the start-up/safety relief was determined by a small control orifice in the relief valve. The oil flow through this orifice was exceedingly small and completely leaked past the directional valve spool back to tank at 600 psi. Replacing the directional valve solved the problem.
