Hydraulic oil performs four basic functions. Their primary function is to create force and motion as the flow is converted to pressure near the point of use. Second, by occupying the space between metal surfaces, the fluid forms a seal, which provides a pressure barrier and helps exclude contaminants. A third function – often misunderstood – is the lubrication of metal surfaces. The fourth and final function provided by the hydraulic fluid is the cooling of system components.

If anyone of these functions is impaired, the hydraulic system will not perform as designed. Worse yet, sudden and catastrophic failure is possible. The resulting downtime can easily cost a large manufacturing plant thousands of dollars an hour. Hydraulic-fluid maintenance helps prevent or reduce unplanned downtime. It is accomplished through a continuous program to minimize and remove contaminants.

Yuneng\’s hydraulic oil filtration system adopts a two-stage filtration structure, a large-capacity particulate matter and a multi-stage filtration system to ensure high filtration accuracy.
