Abstract
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 ...
