柱塞泵配流盘的设计及其有限元分析

Design and Finite Element Analysis of Plunger Pump Distribution Plate

柱塞泵在吸油和压油过程中,会给配流盘造成一定影响,这种压力会使配流盘发生位移变形。针对该问题,提出在配流盘材料中加入一定量镍元素,使材料变成镍铜合金,以此来减少配流盘位移变形程度。另外,分别对黄铜还有镍铜合金运用Ansys仿真分析,得到位移变形最小的材料,以此来提高配流盘耐用程度。

During the process of oil absorption and oil pressure, the plunger pump will have a certain influence on the distribution plate, which will cause displacement deformation of the distribution plate. Aiming at this problem, it is proposed to add a certain amount of nickel element to the material of the distribution plate to make the material become nickel-copper alloy, thereby reducing the displacement deformation degree of the distribution plate. In addition, the Ansys simulation analysis of brass and nickel-copper alloy was used to obtain the material with the smallest displacement deformation, so as to improve the durability of the distribution plate.
