摘要

针对轴向柱塞泵流量脉动大且难以控制的问题

提出了一种通过机械安装减小轴向柱塞泵脉动的主动控制方法。机械安装中将2个柱塞泵的吸油口相连

2个柱塞泵的排油口相连

柱塞泵轴端装有同步带轮并用同步带连接

以实现柱塞泵错相位并联。从轴向柱塞泵流量基础理论入手

以降低轴向柱塞泵流量脉动为目的

对2个奇数(偶数)柱塞的柱塞泵错相位并联安装时的脉动进行了分析

并与单个奇数(偶数)柱塞泵流量脉动进行了对比

在此基础上通过Matlab对轴向柱塞泵的瞬时流量进行仿真。结果表明:2个奇数(偶数)柱塞的柱塞泵错相位并联安装时

瞬时流量增加了2倍

脉动减小且为单个柱塞泵脉动的1/4。该方法可为提高液压系统稳定性研究提供参考。

Abstract

An active control method was proposed to reduce the flow pulsation in axial plunger pumps by mechanical installation. In the process of mechanical installation

oil suctions of two plunger pumps were linked together

oil discharges of the two plunger pumps were connected together

and the shafts of the plunger pumps were equipped with synchronous pulley which was linked with synchronous belt

so that the two plunger pumps could be installed in parallel with stagger phase form. According to the basic theory of axial plunger pump flow

the analysis was performed on the flow rate pulsation of the two plunger pumps with odd(even)plungers in stagger phase parallel installation

and the flow rate pulsation of the two plunger pumps with odd(even)plungers was compared with that of single plunger pump with odd(even)plungers. Then the instantaneous flow rate of the axial plunger pump was calculated with Matlab. The results show that the flow rate pulsation of the two plunger pumps with odd(even)plungers in stagger phase parallel installation is 1/4 times that of single plunger pump. The method proposed in this study could be useful in the research on increasing hydraulic system stability.
