An axial piston pump with large displacement has been used as the pump under test, a measurement system has been put forward and flow ripples at different pressures have been determined.

并以一台较大排量的轴向柱塞泵为被试泵，建立了流量脉动测试系统，实现了多种压力下被试泵流量脉动的测试。

The test results have proved that the flow rate widely varied and the pump efficiency is high when the pump outlet line structure was altered and the outlet pressure was controlled in a special limit.

试验结果表明，改变泵出口管线结构，使泵出口压力在一定范围内工作时，流量变化大，而且泵效率较高，可以作为泵调整参数的一种手段；
