1, hydraulic oil

Most of them are used in hydraulic systems, but also in cleaning and testing. The causes of hydraulic oil pollution mainly include metal powder formed by friction, carbon residue formed by extrusion friction, sludge, moisture, and the like. The system requires relatively high oil content, preferably within the NAS9 level, and the water content is 100 PPM.

2, gear oil

Gear oil is mainly used for the lubrication of gear transmissions of heavy machinery. The requirements for impurities are much lower than those of hydraulic systems. The viscosity of oils used varies according to different equipment. The cause of pollution is mainly friction metal powder, sludge, and water.

3, turbine oil

Turbine oil is mainly used in turbine generator sets of power plants. The main cause of pollution is moisture and impurities.

4, transformer oil

High water content requirements
