Product Description
hydraulic pump manufactory REXROTH Axial piston variable pump A4VG Series 40 High total efficiency
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 application field of piston pump; Radial piston pump is a kind of piston pump whose reciprocating 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.
