Thrust plate of axial plunger pump

Abstract

The invention discloses a thrust plate of an axial plunger pump. The thrust plate is provided with a kidney-shaped hole, wherein the kidney-shaped hole is located in the middle of the thrust plate, along hole is formed in the circumferential direction of the concentric circle of the thrust plate, and an unloading groove and a damping hole of the same structure are formed in the upper end of the kidney-shaped blind hole; and the damping hole is composed of a primary hole, a secondary hole and a tertiary hole which are concentric and sequentially reduced in diameter, wherein the back surface ofthe side of the unloading groove is sequentially provided with the primary hole, the secondary hole and the tertiary hole, the tertiary hole communicates with the outermost side of the unloading groove, and the width angle of the unloading groove is 83.5 degrees. The thrust plate has the beneficial effects that the flow pulsation condition of the unloading groove on the thrust plate is analyzed and various forms of flow pulsation curves are obtained by taking a thrust plate of a 112D swash plate type axial plunger pump as an example, and finally the optimal size of the thrust plate is obtained from the reduction of pulsation, so that the thrust plate is optimized and designed, and the fluid noise generated when the high-pressure axial plunger pump works is further reduced.

Description

technical field [0001] The invention belongs to the technical field of axial piston pumps, and in particular relates to a noise-reducing flow distribution plate. Background technique [0002] The high-pressure swash plate axial piston pump has the advantages of high working pressure and high power density. However, when the high-pressure axial piston pump is in use, it will generate a lot of noise. These noises will cause great pollution and will be harmful to the human body. It will cause great harm, so in order to improve the working environment of the staff, the working noise of the high-pressure axial plunger must first be reduced. Contents of the invention [0003] Aiming at the problem of high noise in the prior art, a flow plate of an axial piston pump is provided, which is applied to a 112D swash plate axial piston pump and can effectively reduce noise. [0004] A distribution plate of an axial plunger pump, which has a waist-shaped hole, the waist-shaped hole is ...
