摘要
从端面密封结构方面和密封性能稳定性影响因素方面,对在用和放置发动机密封性能检查中出现的泵端面密封泄漏量严重超标现象进行了深入分析以及模拟试验验证,并进行实际工作考核验证,给出了不影响使用的明确结论。
The phenomena of serious leakage from the end-face sealings of liquid rocket engine turbopumps were analyzed. Its effects on sealing performance were experimentally studied through hot test. The tests results show that sealing performance was not degraded by the existing leaking rate.
