Where does built-in hydraulic contamination come from?

October 30, 2024 By Mary Gannon Leave a Comment

Manufacturing all hydraulic components creates weld slag and splatter, which can end up as built-in contamination.

By Josh Cosford, Contributing Editor When I sat in my first fluid power class 18 years ago, I remember learning about built-in contamination and how the reservoir was the biggest offender. The welds and their slag were the biggest problems, the teacher stated, but a close second was the debris from pipe threading machines. Looking back, it’s … [Read more...] about Where does built-in hydraulic contamination come from?

Fluid oil analysis particle contamination patch test

By Josh Cosford, Contributing Editor Particle contamination is the proverbial lord of the contamination cartel. Particles get all the attention in this world, and rightfully so. Particle contamination-related failures likely outpace water, varnish and heat combined (yes, heat is a form of contamination). It would come as no surprise, then, that … [Read more...] about Hydraulic oil analysis part 3 — measuring and controlling particle contamination

In-thank mobile return line filters Image courtesy of Hydac

By Josh Cosford, Contributing Editor If you've ever been (un)lucky enough to open up a 30-year-old hydraulic reservoir, you know how shockingly grimy they can be. I've seen 3 in. of sludge, filings and particles sedimentate enough to clog the suction filter. That hydraulic power unit had a return filter in addition to its clearly unhelpful … [Read more...] about The importance of hydraulic reservoir filtration systems

Do special hydraulic fluids require special filters?

June 12, 2023 By Mary Gannon Leave a Comment

Phosphate esters are classified as synthetic fluids and can cause negative effect to hydraulic filtration, such as acid buildup. To combat this, most filters and elements, such as these from Hydac, can be used with most of these fluids.

By Josh Cosford, Contributing Editor Hydraulic systems play a critical role in various industries, powering heavy machinery and equipment with precision and efficiency. The performance and longevity of these systems heavily rely on the cleanliness and quality of the hydraulic fluid. Contamination in hydraulic fluid can cause significant damage … [Read more...] about Do special hydraulic fluids require special filters?

How to ensure hydraulic fluid cleanliness outside of filtration

May 31, 2023 By Mary Gannon Leave a Comment

Cleaning hydraulic reservoirs regularly, like this one that's covered with dirt, can prevent contamination, especially before filling with clean oil.

Hydraulic fluid cleanliness is crucial for hydraulic systems' reliable operation and longevity. However, while filtration is critical in keeping hydraulic fluid clean, it is not the only factor that impacts fluid cleanliness. This article will discuss some tips to ensure hydraulic fluid cleanliness aside from the obvious filtration … [Read more...] about How to ensure hydraulic fluid cleanliness outside of filtration

Cylinder piston seals AdobeStock_25655813

By Josh Cosford, Contributing Editor How long is a piece of string? So what? Did you think you'd get a straight answer on a subject like "what is the best cylinder piston seal?" There is no best piston seal, just like there is no best car (it's the Mazda Miata, by the way). If you're in the snow belt with five kids, your best car is a … [Read more...] about What is the best cylinder piston seal?

When are vacuum dehydrators necessary?

March 24, 2022 By Mary Gannon Leave a Comment

Schroeder NAV oil dehydrator 5_cutout_FINAL

You might be surprised to hear that oil and water do mix. Of course, they won't mix when poured together in a glass and stirred with a spoon. But forces at play to destroy your hydraulic system find ways to allow much more water to saturate and emulsify with your innocent hydraulic oil. Heat, oxidation and chemical contamination increase the … [Read more...] about When are vacuum dehydrators necessary?
