单管焊缝和螺接点检漏是卫星在总装阶段检漏工作的一项主要内容。采用氦质谱检漏仪进行单点检漏的基本流程为:充/排气管路连接→系统氦气加压→采用吸枪模式检漏→检漏后氦气泄压。整
Single-tube weld and screw-point leak detection is the main stage of the satellite assembly leak testing a major part. The basic procedure for single-point leak detection with a helium mass spectrometer leak detector is: Charge / Exhaust gas line connection → System helium pressurization → Leak-sniffing mode → Leakage after leak detection. whole
