Problems solved by technology

There is also an axial piston pump in which the distribution plate and the distribution surface of the cylinder body of the imported pump are partly spherical. Compared with the flat disk, this design can moderately alleviate the friction of the distribution part, so the design pressure of the pump can be moderately increased. , but such an axial piston pump also has the problems of complicated machining of the curved surface of the workpiece at the distribution part, and the axial piston pump and its accessories are extremely expensi

Abstract

The invention provides a variable axial plunger pump. The variable axial plunger pump is a radial fluid distribution pump and comprises a drive shaft driven to rotate by an external force, a cylinder body connected with the drive shaft, a fluid distribution sleeve, a fluid distribution shaft and a variable control part enabling the plunger pump to variably output a fluid. The cylinder body, the fluid distribution sleeve and the fluid distribution shaft are coaxial with the drive shaft. Compared with a traditional radial plunger pump, the variable axial plunger pump mainly has the advantages of being simple in structure, small in size and light in weight. Compared with a traditional axial plunger pump, the variable axial plunger pump mainly has the advantages that the rotation speed of the pump can be remarkably improved, working pressure can be remarkably increased, nominal flow rate can be improved in a multiplied mode, or the volume efficiency of the pump can be remarkably improved under the condition of the same working pressure, and noise can be reduced by more than 10 decibels.

Description

technical field [0001] The invention relates to the field of plunger pumps, in particular to a variable variable axial plunger pump. Background technique [0002] The plunger pump is a pump that relies on the reciprocating movement of the plunger in the cylinder to change the space volume of the sealed cavity to achieve oil suction or oil discharge. In the prior art, there are mainly two types of multi-piston piston pumps, one is an axial piston pump, and the other is a radial piston pump. [0003] Among them, the radial plunger pump means that the plungers are radially arranged and installed in the rotor, and the rotor and the plungers are driven to rotate by the motor. The plunger is pressed against the inner wall of the stator by the centrifugal force and the oil supplied by the low-pressure high-flow gear pump. Its structure is as Figure 4 Shown, wherein, 01, plunger, 02, rotor, 03, bushing, 04, stator, 05, oil distribution shaft. When the rotor rotates clockwise to ...
