The electric timing of the hydraulic accessory unit causes the Oil Pumps to rotate. The pump will suck oil from the oil pump to pump oil, and convert the mechanical energy into the force of the hydraulic oil. The hydraulic pressure of the manifold block can complete the adjustment of pressure, flow, and direction, and then receive and transmit it from the outside to In the oil cylinder or in the motor, it controls the rotation direction, strength and speed of the hydraulic power unit in this way, and pushes the hydraulic machine to do mechanical work. The structure of the hydraulic station is mainly distinguished according to the structure of the pump installation, the location of the device and the way of cooling.

The drawing or processing of the sealing groove of the hydraulic vane pump is a prerequisite to prevent premature damage to the oil seal. If the groove size of the static seal between the piston and the piston rod is too small, the seal ring has no small movement in the groove At this point, the bottom of the sealing ring will be damaged due to the effect of the counter-effect, and cause leakage. The oil seal groove of the Internal Gear Pumps accessories is mainly drawn by the planning of the groove part, the shape, the size and the roughness of the sealing surface. Degrees should be strictly stopped in accordance with standard requirements.
