Description
Technical Field

Background
The plunger pump is an important device of the hydraulic system. The plunger reciprocates in the cylinder body to change the volume of the sealed working cavity so as to absorb and press oil. The plunger pump has the advantages of high rated pressure, compact structure, high efficiency, convenient flow regulation and the like, and is widely applied to occasions with high pressure, large flow and flow regulation, such as hydraulic machines, engineering machinery and ships. The inclined disc type axial plunger pump consists of an inclined disc, a plunger piston, a combined body, a valve plate and a transmission shaft, wherein an inclined angle gamma is formed between a cylinder body and the inclined disc. The plungers are uniformly distributed in the cylinder body, and the heads of the plungers are tightly pressed on the swash plate through a spring return mechanism and the action of oil pressure. The transmission shaft drives the cylinder body to rotate through a spline, and the swash plate and the port plate are fixed. When the transmission shaft can rotate in the anticlockwise direction, the plunger not only rotates along with the cylinder body, but also makes reciprocating linear motion in the plunger hole of the cylinder body.
The existing variable axial swash plate plunger pump is easy to be mistakenly collided to cause flow change because the variable adjusting parts are not protected, and the noise is larger when the variable axial swash plate plunger pump runs.
