| 摘 要： | 研究密封管路液态工质与示漏气体he间的漏率等效关系,对提高检漏工作的准确性和可靠性有着重要意义.文章以环控生保系统中密封管路所用的液态工质(全氟三乙胺,乙二醇)为研究对象,对液体的流态及泄漏的相态进行理论分析,得出液态工质与he气漏率等效关系的数值区间,并利用质谱分析技术,采用金属压扁型漏孔模拟真实的泄漏孔隙进行试验研究.试验结果表明,液态工质与示漏气体的漏率比值在理论数值区间之内,流动过程中呈现两相流的状态,并且乙二醇的漏率要比he气小,而全氟三乙胺的漏率要比he气大.试验结果为研究液体泄漏过程及液、气漏率等效关系提供了基本方法和基础数据.

| Abstract: | The leak equivalent relationship between liquid and helium is an important issue to avoid the leaking of liquid medium in the sealed pipes and to improve the accuracy and reliability of leak detection.This paper studies the liquid working mediums(C2H6O2 and C6F15N) in the sealed pipes of the environment control and life protection system.The ranges for leak rate equivalent relationship between liquid and helium were theoretically analyzed.The leak rates of liquid and helium through metal aperture were measu... |
