It is suitable for various machines where the driving device is separated from the hydraulic station. The hydraulic station is connected to the driving device with an oil pipe, and the hydraulic system can achieve various prescribed actions. However, when the hydraulic station flows back, the oil pollution is large and there are many impurities, which will affect the use of the hydraulic station. For example, as shown in the arm servo hydraulic station with Chinese patent application number CN202122940452.6, the pump body extracts the hydraulic oil inside the oil tank and transports it to the valve group through a pipeline. The valve group is connected to the hydraulic rod at the arm to provide power for the hydraulic rod at the arm. The oil pressure at the pump body outlet can be detected in real time through the set pressure sensor, so that the operating parameters of the pump body can be adjusted in time according to the oil pressure to make the hydraulic rod at the arm operate normally.

[0003] However, due to the lack of purification of the hydraulic oil returning from the hydraulic station, a large amount of oil and impurities will accumulate at the bottom of the hydraulic station, which will increase the amount of hydraulic oil supplied by the hydraulic station when the hydraulic station pumps oil again, thus causing a waste of hydraulic oil.

A dirt storage cavity for storing oil is provided at one end of the filter plate 2 away from the filter plate 1.
