齿轮泵冲击试验中基础压力的研究

Research for The Base Pressure in The Impulse Test for Gear Pump

本文就齿轮泵耐久性寿命冲击试验中基础压力对被试泵及其系统的影响做了具体的研究，阐明基础压力的大小不应为零，应保持一个恰当的数值。

In this paper,the influence of the pump to be test and the system is researched that is made by the base pressure in the inpulse test for durable life of gear pump.It is expounded that the base pressure should be a suitable numerical value instead of zero.
