How do you remove water from your hydraulic system?
It’s common knowledge that particulate contamination is unwanted in hydraulic systems. Contamination in hydraulic oil can damage mobile and industrial machinery. Of as much concern should be water in oil, as it too can lead to component failure. Water in hydraulic fluid can be seen as free, dissolved or emulsified and can reduce hydraulic … [Read more...]
2-in-1 suction return filter for cold start applications
In tractors with a mixed response common oil circuit for transmission and power hydraulics, a suction filter is usually used to protect the pump and a return filter to ensure oil cleanliness. To protect the system during cold start, a coarse safety screen is often also installed in the suction line, but this a disadvantage of this design is that … [Read more...]
When are static seals used in hydraulics?
By Josh Cosford, Contributing Editor Static seals are used in hydraulic applications where two mating surfaces or edges require positive sealing. A static seal, by definition, is one that remains stationary and subjected to no movement and its related friction. A static seal may be exposed to hydraulic pressure on both sides or be exposed to … [Read more...]
Trelleborg’s tensioner cylinder seals exceed 20-year lifecycle rating
Seals used in offshore rig tensioner cylinders must meet the same rigorous lifecycles as the cylinders themselves. Because offshore environments are harsh and installation and maintenance can be difficult, tensioner cylinders must have a 20-year life. That was why, more than 20 years ago, Trelleborg Sealing Solutions conducted research, determining … [Read more...]
