Rexroth piston pump

Plunger pump is an important device in hydraulic system. It relies on the reciproing movement of the plunger in the cylinder block to change the volume of the sealing working cavity to achieve oil suction and pressure. The piston pump has the advantages of high rated pressure, compact structure, high efficiency and convenient flow adjustment.

Working principle of plunger pump

The piston pump is divided into two representative structural forms: axial piston pump and radial piston pump; Because radial piston pump is a new type of high-efficiency pump with high technology content, radial piston pump will become an important part of the appliion field of piston pump; Radial piston pump is a kind of piston pump whose reciproing motion direction is perpendicular to the driving shaft.The oil flow in and out of the pump body and the flow passage on the valve shaft are controlled by the oil suction port on the valve shaft. The liquid pressure generated in the pump body is absorbed by the surface of static pressure balance.
