Product Description
The hydraulic pump of an excavator is a key component in the hydraulic system of an excavator. Its main function is to convert the mechanical energy of the engine or motor into hydraulic energy to provide power for the entire hydraulic system. The working principle of the hydraulic pump is based on the volume change of the hydraulic oil. In this way, pressure is generated on the liquid, thereby driving the various working devices of the excavator to move.

Main types and features
Variable displacement pumps and fixed displacement pumps:

Variable displacement pumps: can adjust the output flow according to work requirements, suitable for occasions where the flow needs to be changed frequently1.
Fixed displacement pumps: the flow cannot be adjusted, suitable for occasions where the flow demand is constant1.
Gear pumps, vane pumps and plunger pumps:

Gear pumps: small size, simple structure, low cost, but there are certain leakage and wear problems1.
Vane pumps: uniform flow, smooth operation, low noise, high pressure and volumetric efficiency, complex structure1.
Plunger pumps: change the volume through the reciprocating motion of the plunger, suitable for high-pressure occasions
