[0002] The hydraulic pump station is also called a hydraulic station. The motor drives the oil pump to rotate. The pump sucks oil from the oil pump and then pumps it, converting mechanical energy into the pressure energy of the hydraulic oil. The hydraulic oil is adjusted in direction, pressure and flow by the hydraulic valve through the integrated block (or valve combination) and then transmitted to the oil cylinder or oil motor of the hydraulic machinery through the external pipeline, thereby controlling the change of direction, force and speed of the hydraulic motor, and driving various hydraulic machinery to do work. The hydraulic pump station can be divided into top vertical, top horizontal and side mounted types according to the installation position of the pump device.
