The hydraulic pump is the power component of the hydraulic system. Its function is to convert the mechanical energy of the prime mover into the pressure energy of the liquid. It refers to the oil pump in the hydraulic system, which provides power to the entire hydraulic system. The structural forms of hydraulic pumps generally include gear pumps, vane pumps and plunger pumps.
The working principle of a hydraulic pump is that movement brings about a change in the volume of the pump chamber, thereby compressing the fluid so that the fluid has pressure energy.
