摘要
雷达天线座液压系统中常用到一些特种密封圈。为了检测其在实际工作中的磨损寿命,需要对它进行若干小时以上的模拟跑合试验。文中介绍了一种全新的密封圈跑合装置的组成、原理、结构、控制方式及应用。
Some special seal rings were frequently used in hydraulic pressure system of radar antenna pedestal. In order to test its wear-life in practical working condition, we need to make an experiment on it for over some hours to simulate practical running-in. This paper introduced a new device for the seal ring running-in including its form,elements,structure,control mode and related application.
