摘要
大型空间环境模拟试验设备的液氮系统能否顺利启动是决定液氮系统设计成败的一个关键的问题.文章提出了影响单相密闭循环液氮系统启动的两个关键因素,以及如何在液氮系统设计中加以解决.通过初步调试证明,液氮系统能够很好地解决大型空间环境模拟设备液氮系统启动困难的问题.
Whether the large space simulator liquid nitrogen system can be successfully started is a problem for the design of liquid nitrogen system.This article puts forward two main factors to influence the starting of liquid nitrogen system,and introduces the ways to solve this problem.It has been proved by test that the problem of large space simulator liquid nitrogen system starting has been solved successfully in Simulator liquid nitrogen system.
