The hydraulic pump is the power component of the hydraulic system, which is driven by the engine or motor, sucks oil from the hydraulic oil tank, forms pressure oil, and discharges it to the actuator. The hydraulic pump is divided into gear pump, plunger pump, vane pump and screw pump according to the structure.
1. According to whether the flow can be adjusted, it can be divided into variable displacement pump and fixed displacement pump. The output flow that can be adjusted as required is called variable displacement pump, and the flow that cannot be adjusted is called constant displacement pump.
2. According to the pump structure commonly used in the hydraulic system, it can be divided into gear pump, vane pump and plunger pump.
Gear pump: small size, simple structure, lax requirements on oil cleanliness, and low price; However, the pump shaft is seriously worn and leaks due to unbalanced force.
Vane pump: divided into double acting vane pump and single acting vane pump. The pump has uniform flow, stable operation, low noise, higher working pressure and volumetric efficiency than gear pump, and more complex structure than gear pump.

Plunger pump: high volumetric efficiency, small leakage, can work under high pressure, mostly used in high-power hydraulic systems; However, the structure is complex, the requirements for materials and processing accuracy are high, the price is expensive, and the requirements for oil cleanliness are high.
