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: firstly, insufficient supply of hydraulic oil will lead to the suction of the hydraulic oil pump. Wear and tear will quickly cause the hydraulic oil pump to be seriously damaged to scrap; secondly, air suction makes the hydraulic oil mixed with air, which causes the compression elasticity of the hydraulic oil to increase, which reduces the volumetric efficiency of the hydraulic oil pump and other working devices, resulting in a decrease in the working efficiency of the entire hydraulic system. At the same time, the air in the hydraulic oil is compressed to form compressed gas during the operation of the oil pump and the working device. When it reaches a certain pressure, it will explode. The formation of air pockets will damage the sealing surface and cause the oil pump and the working device to wear out quickly. The prevention method is to frequently check the hydraulic oil in the hydraulic oil tank to ensure that the amount of hydraulic oil is within the normal use range.

The hydraulic oil filter element in the pressure oil tank has been used for too long, and the impurities in the hydraulic oil are adsorbed on the surface of the filter element and block the filter element, which will also cause the oil pump to absorb insufficient oil and cause suction. Regular replacement of the hydraulic oil filter element is the most effective prevention method.

If the hydraulic oil is used for too long without changing, the impurities in the hydraulic oil (iron filings, copper filings, dust, etc.) will accumulate more and more, and the fine particle size will become smaller and smaller. Such impurities are sometimes fundamental to the naked eye. What is invisible is very small, it will easily pass through the hydraulic oil filter element. At the same time, if the hydraulic oil is used for too long, the various characteristics of the hydraulic oil, such as lubrication performance, viscosity characteristics, anti-wear performance, and stiffness characteristics, will be greatly reduced. Impurities in the hydraulic oil are brought to various working devices and control components through the working cycle, directly causing rapid wear of the hydraulic components of the entire hydraulic system. The preventive method is to change the hydraulic oil regularly, or take samples for inspection regularly, and replace it in time if it is found to exceed the standard.
