Hydraulic oil is the direct medium for the work of the hydraulic system. All the power and operation control of the hydraulic system are transmitted by the hydraulic oil. The main parts that cause the “deterioration” of the hydraulic oil are the hydraulic oil tank, the hydraulic oil filter, and the wear of the hydraulic parts. generated impurities, etc.
1. The hydraulic oil tank is the place to provide hydraulic oil, heat dissipation and cooling, deposit impurities and discharge the air of the hydraulic system.

First of all, insufficient supply of hydraulic oil will lead to the suction of the hydraulic oil pump, which will cause insufficient oil supply of the hydraulic oil pump, which will directly lead to the wear of the hydraulic oil pump, which will soon cause the hydraulic oil pump to be seriously damaged and scrapped.

Secondly, air suction will also mix air into the hydraulic oil, which will increase the compression elasticity of the hydraulic oil and reduce the volumetric efficiency of the hydraulic oil pump and other working devices. At the same time, the air in the hydraulic oil is compressed during the operation of the oil pump and the working device. The cavity will damage the sealing surface and cause the oil pump and working device to wear quickly.

The preventive method is to check the hydraulic oil in the hydraulic oil tank frequently to ensure that the amount of hydraulic oil is within the normal range.
