A sniffer with a vacuum cover-helium leak detector set was developed for pressured vessels detection and some vacuum pumping sets suitable for pumping huge water vapor were developed also. 对压力容器检漏,开发了真空罩吸枪-氦质谱检漏系统,还研制了适于抽除大量水汽的检漏真空机组。
Air in Leakage of the Vacuum System of Turbine Units Detected by a Portable Helium leak Detector 氦质谱仪进行汽轮机真空系统检漏的实践
The vacuum performance of threaded-adhesive joints was investigated experimentally using the helium mass spectrometer leak detector. 本文采用氦质谱仪对螺纹粘接接头的真空性能进行了实验研究。
We had measured the vacuum tightness of the steam turbine group of Xuzhou Power Plant through a helium mass spectrum leak detector. 利用氦质谱检漏仪对徐州发电厂的汽轮机组进行真空严密性检测。
