[0002] The plunger pump is an important hydraulic device, which is generally driven by an electric motor and converts the mechanical energy of the motor shaft's rotational motion into hydraulic energy. Its principle is to rely on the reciprocating motion of the plunger in the cylinder to change the volume of the oil chamber at the top of the plunger to achieve oil suction and oil pressure.
