液压设备使用中的元件泄漏与防治是液压专业人员普遍关注的问题。尽管近年来人们在液压系统及元件的密封性能、密封材料、密封结构和方法等方面做了大量的研究工作,但在及时有效地查出液压元件的泄漏部位方面,目前的检查方法还不够方便和准确。现介绍一种气压检查法,供参考。 气压检查法就是利用气体密度小、渗透力强的特点,针对不同的元件,充入一定压力的压缩空气,然后将液压元件浸入装有液压油的容器中(或在元件的密封部位徐上发泡剂),根据气泡 Hydraulic components in the use of the components of the leakage and prevention of hydraulic professionals generally concerned about the problem. Although a great deal of research work has been done on the sealing performance of hydraulic systems and components, sealing materials, sealing structures and methods in recent years, the current inspection methods are not convenient for detecting leakages of hydraulic components in a timely and effective manner And accurate. Now introduce a kind of pressure check method, for reference. Pneumatic inspection method is the use of gas density is small, strong penetration of the characteristics of different components, filled with a certain pressure of compressed air, and then the hydraulic components immersed in a container containing hydraulic oil (or in the sealing parts of the element Xu foaming agent ), According to bubbles
