Abstract

The invention discloses an optimized design method for a valve plate of an axial piston pump. The method is characterized by comprising the following steps that S1, the over-flow area of a valve plateof a swash plate axial piston pump is calculated; S2, the flow of the axial piston pump is calculated; S3, the leakage flow is calculated; S4, a theoretical model of the single piston pump is established; S5, an over-flow area curve of a triangular unloading groove, an over-flow area curve of a damping hole and an over-flow area change curve of a waist-shaped hole are respectively drawn through software according to the calculation of the S1; and S6, a flow pulsation curve of the single piston is obtained according to analysis of the over-flow area. The method has the following beneficial effect that taking the valve plate of the 112D swash plate axial piston pump as an example, the flow pulsation condition of the unloading groove on the valve plate is analyzed and the flow pulsation curves in various forms are obtained, and finally the optimal size of the valve plate is obtained under the condition that pulsation is reduced, so that the valve plate is optimized and designed, and thefluid noise generated when the high-pressure axial piston pump works can be further reduced.

Description

technical field [0001] The invention belongs to the technical field of axial piston pumps, and in particular relates to an optimal design method for 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, an optimal design method for a flow plate of an axial piston pump is provided. [0004] A method for optimal design of a flow plate of an axial piston pump, characterized in that it comprises the following steps: [0005] S...
