溢流阀动态性能的实验分析

The Experiment and Analysis of Dynamic Behaviour for Relief Valves

本文用谱分析的方法对溢流阀工作时的动态性能进行了实验研究．比较在不同工作压力下主阀和导阀的功率谱图，总结了溢流阀的工作同供油压力脉动之间的相互关系．并且提出一种改造设计的方案，效果较好，对生产有一定的实用价值．

In this paper,the dynamic behaviour of a relief valve in operation is experimentally considered by means of spectrum analysis.With checking the power spectrum diagrams of the main spooland the pilot poppet at different working pressures,a mutual relation is given between performanceof relief valves and pressure fluctuation of fluid supply. Besides a improved scheme is presentedwhich proves effective and have a certain practical value for mallufacture.
