摘要

液压系统中的液压油流经节流阀口时,会产生气穴现象,甚至产生发光现象,通过介绍产生发光的原因及影响气穴大小及发光强弱的影响因素,并采用试验验证的方法来检测阀口前后压差的改变对气穴发光的影响,证明了压差是影响发光的因素,并且随着压差的增大气穴发光现象更加严重,从而找到减弱气穴发光的方法。

Abstract

For hydraulic systems, cavitation occurs when hydraulic oil flows through the throttle port, even when serious this problem produce luminous phenomenon. This paper introduces the causes of luminescence and the influencing factors affecting the size of cavitation and the intensity of luminescence. And this paper aims to test the influence of the pressure difference before and after the valve opening on the cavitation luminescence by experimental verification. Finally it proves that the pressure difference is the influencing factor of luminescence, and with the increase of pressure difference, the phenomenon of cavitation luminescence is more serious. So then it has found a way to reduce the cavitation luminescence.
