采用非真空氦质谱累积法进行航天器密封系统的总漏率测试时,需要检漏容器对密封系统泄漏出的氦气进行收集。本文通过理论分析,并用正压氦漏孔模拟航天器密封系统的泄漏进行试验验证,得出了检漏容器的密封性能对航天器密封系统总漏率测试的影响,为检漏容器的泄漏给出了建议指标。
The non-vacuum Helium mass spectrometry method for total leak testing of a spacecraft containment system requires a leak detector to collect helium leaking from the containment system. In this paper, through the theoretical analysis and experimental verification of the leakage of the spacecraft sealing system with positive pressure helium leak holes, the influence of the sealing performance of the leak detection container on the total leakage rate test of the spacecraft sealing system is obtained, Out of the recommended indicators.
