Electromechanical (EM) actuating systems have been increasing in popularity for some time. They have replaced pneumatic and hydraulic systems in many light-duty applications. Today,another option (such as the Parker HAS 500) is available: a hybrid of EM and hydraulic actuation systems, which combines the best of both worlds.
Below we will compare EM and hydraulic systems and take a quick look at the new hybrid system.
If you are repairing or maintaining hydraulic equipment, you make and re-make connections daily. You know to use plugs and caps to plug open ports and cap disconnected hoses, in order to keep the the dirt out and oil in. This method works for most connections, but when it comes to flanges most mechanics' oil containment method is to shove a rag into the open port, and another in the end of the disconnected hose (or tube assembly).
Now, there's another option – using FlangeLock™. The FlangeLock™ allows for quick, simple sealing of open SAE Code 61, Code 62 & CAT-style hydraulic flange connections without tools. It is the ultimate spill and contamination control during disconnecting and re-connecting flange fittings.
We have written several blogs in the past about risks associated with using equipment with worn-out hydraulic hoses and how to spot the unsafe hoses before they fail. The intended audience of these blogs had been plant managers, equipment maintenance managers, and equipment mechanics, but a recent experience with a rented trencher made me re-evaluate who else should be learning about how to spot an unsafe hydraulic hose.
What if you just rent hydraulic equipment from your local rental yard? Just because you are not in charge of its maintenance and safety does not mean that you cannot be affected by a rental company's lackadaisical approach to equipment maintenance.
Depending on your equipment, an oil change can be a complicated, potentially messy process. It is often necessary to remove pans full of oil that can spill onto the floor, slosh onto workers, or contaminate the environment. The steps for the process can also change from vehicle to vehicle, requiring special training and instructions for each one. For companies with a wide variety of equipment, this can be cost prohibitive and time consuming.
A standardized process like Parker’s QuickFit System simplifies the steps and prevents spills and injuries.
Let’s face it – rust happens. Whether it’s equipment that has been exposed to the elements over time or a repair job that someone brings into your shop with frozen, corroded parts. Chains, gears, pipe thread connections, screws, nuts and bolts and all types of metal tools – any of these can build up rust and other deposits from age, misuse or neglect. You need to be able to remove stuck parts to complete a replacement or repair fast. But what is the best way to free rusty nuts and bolts efficiently?
|When it comes to cleaning up after working with paint, oil, grease, tar and other types of tough grime encountered in industrial settings, your hand wash needs to be equally tough. Regular soap isn’t designed to handle oily substances and doesn’t always penetrate the grime left in hands’ creases and crevices. Washing too often, too vigorously, or with cleaners that contain harsh chemicals can dry out and damage skin. Mechanics often develop chronically dry, cracked skin on their hands due to the substances they work with and the amount of washing it takes to remove it. So how do you clean your hands at work but also keep skin healthy and moisturized?|
According to Fluid Power Journal article, "Industry and user experience agree 70% of [hydraulic hose] failures are a direct result of abrasion or external damage—yet many could be prevented."
Hose assemblies that are exposed to regular cycles of heavy friction must be closely monitored for abrasion damage to prevent equipment failure and protect the safety of your workers. Many over-the-sheave applications, such as forklifts, cranes and scissor lifts, need specialized hose shields and covers to protect the hose from abrasion damage. A variety of abrasion resistance solutions are available through Parker to suit specific needs based on the application and work environment. These solutions include abrasion sleeves, protection shields, spiral hose guards and the built-in abrasion resistant hose covers in Parker’s ToughCover, SuperTough and ToughJacket series.
Abrasion sleeves include products such as Parker’s Partek, a lightweight urethane-coated nylon sleeve designed for abrasion resistance and for bundling hose assemblies together. Partek’s unique tubular weave construction allows for the hose to move freely within the sleeve’s exceptionally smooth walls, preventing internal abrasion issues. Partek is available in two versions - Partek “AS”, which is strong enough to withstand over 200,000 abrasion cycles without damage or failure, and Partek “PS”, which can withstand more than 50,000 abrasion cycles. Partek has the advantage of being able to be installed post-assembly, meaning that you can add this product after determining the level of abrasion resistance that your existing hose assembly will need.
For more pinpointed abrasion protection, hose shields provide a low-cost solution for small sections of hose that come into contact with abrasive conditions. The plastic shields are connected with cable ties for easy assembly that does not require disconnecting or removing the hose prior to installation. Hose shields are available in 4, 6 and 8 inch lengths for hose I.D.s of ¼ to 2 inches. Hose shields are not recommended for applications that experience heavy abrasion, particularly if more than just a small segment of the hose assembly is exposed to frequent friction.
Parker Spring and Armor Guards can prolong the life of hose assemblies that are exposed to rugged, abrasive conditions. These protective spiral guards are available in a variety of materials and configurations, including clear vinyl, black vinyl, and flat steel. In addition to their abrasion resistant properties, Spring and Armor Guards also prevent hose kinking and provide anti-crush protection.
Parker also offers several polymer spiral wraps that can be added to an existing hose assembly, including the NEXWRAP chafe guard, ParKoil spiral wrap and the PolyGuard heavy-duty hose protector. NEXWRAP can be used to bundle hose, tubing, cables and wiring, protecting the lines from exposure to abrasion. The open spiral design allows for parts of the bundle to be removed without the need to shut down equipment first, preventing downtime. Similarly, the ParKoil polymer spiral wrap can be used to bundle equipment and provides a low-cost solution for abrasion resistance in less-demanding applications. Finally, PolyGuard’s rugged polyethylene cover provides superior abrasion protection and is ideal for bundling high-pressure hose lines.
For the most demanding applications, built-in abrasion resistant hose covers provide the highest levels of protection. Parker offers multiple hoses in their ToughCover, SuperTough and ToughJacket series – you can find more information on each of these hoses on our new Abrasion Resistant Hose selection page. ToughCover is constructed from synthetic rubber and is 80 times more abrasion resistant when compared to Parker’s Standard rubber cover, SuperTough provides 450 times more resistance, and the ToughJacket series is 650 times more durable and abrasion resistant when compared to standard rubber hose cover.
Which abrasion-resistant hose protection should you choose? The answer depends greatly on your equipment’s specific needs and how much friction the hose assemblies will encounter. For example, in boom and cable track applications, the 563TJ hose is ideal due to its low length change characteristics. The majority of hoses shrink at least 2% in a constricted environment, which can be disastrous in booms and cable tracks as this shrinkage must be prepared for to prevent hoses from pulling out of fittings.
Equipment with over-the-sheave hose assemblies can benefit greatly by selecting a tough cover hose. Forklifts, scissor lifts, bucket lift trucks and reach stackers are just a few industrial applications where hose assemblies encounter numerous cycles of abrasive friction.
Available space can also be a major factor to consider when selecting abrasion protection for your equipment. In tight, constricted spaces or in applications where adding extra weight is a concern, using a hose sleeve or guard may not be practical. Abrasion resistant tough covers can reduce the overall assembly weight and their flexibility allows routing through tight spaces. Alternately, hose guards and wraps may be used if the friction encountered is relatively minor and protection needs to be added to an existing assembly.

In water systems, food and beverage, and other applications for transporting media that must remain potable or food-safe, microbes are a constant concern. Algae, mildew and fungi can accumulate inside or outside of tubing due to moisture while they are in use. This accumulation can not only create impurities in the transported substances, but it also leads to premature equipment degradation, which can raise maintenance costs and cause costly break-downs in the production line. Parker has a solution to both problems with their EA Series of tubing.
The truth is that if you are using equipment in the elements, corrosion is inevitable. The question is not if, but when you will have to change the rusted parts. The trick is to find the fittings and adapters that will last as long as possible.
Back in May, you may have read our blog about remote hydraulic system condition monitoring. In that post, we presented Parker’s SensoNODE™ line of sensors, which monitor temperature, humidity and pressure changes in a hydraulic system and can be accessed remotely via Bluetooth® app. However, the connected technology of the Industrial Internet of Things (IIoT) is growing and changing rapidly – just five months after the original post, there is already more to share with you on the topic. First, we will quickly review the three major methods of monitoring the condition of your hydraulic equipment.
In a previous blog from January 2014, Don’t Kill Your Pneumatic System With Bad Air, we wrote about how water, dirt and oil contamination can damage your machine and cause it to run inefficiently. Rust, dust and other impurities can clog air systems and contribute to premature wear and tear on seals and other components. To provide the purest air quality possible, a combination of filters should be connected to the air-flow to capture these impurities before they contaminate the system. However, each compressed air system has unique needs – what may be right for one system may not be the correct choice for another application, when considering environmental factors or fitting a system into a tight space.
When people talk about oil spills, the first image to come to mind is often the large-scale disasters involving oil rigs, oil pipelines or derailed trains. Barrels of oil saturating the soil or dumped into a body of water, with devastating effects on the environment– this is a worst-case scenario come to life. The cost of a major spill, in dollars, man hours and damage to a company’s reputation, can be enormous. What you may not realize, however, is that spill containment on a smaller scale can be very costly as well.
Many scenarios like this one can be prevented with the right monitoring equipment. The ability to take frequent readings of pressure, temperature and humidity can make all the difference when it comes to keeping your equipment running at top performance. Parker’s SensoNODE™ advanced monitoring system provides immediate access to accurate readings of your most vital equipment’s condition, allowing you to identify any potentially damaging changes before a failure occurs.
It’s one of any company’s worst nightmares. A key component of your equipment has failed and production has halted. You determine that the part failed due to overheating or an unforeseen spike in pressure. Whatever the reason, your company loses revenue for as long as the downtime continues – not to mention the inevitable cost of repairs.
In our earlier blog, Early Warnings of Hydraulic System Troubles, we introduced the Parker SensoControl family of diagnostic tools. SensoControl diagnostic tools are designed to help hydraulic system maintenance professionals identify sources of slow operation, increased noise, and elevated temperature. This January, Parker announced a new enhancement to their ServiceJunior product - the color-coded cover.
