真空容器总装后,用气压检漏、卤素检漏、氦质谱检漏,在工厂中大量生产真空容器的过程中,感到不方便。我们在生产实践过程中应用了以H_2O为示漏物质的真空计检漏法。 1.理论依据众所周知,真空容器内的压强是由每秒钟漏进容器的气体与真空泵每秒钟抽出的气体之差所决定的(有漏洞存在,并排除器壁出气的情况下): Vacuum vessel assembly, with pressure leak detection, halogen leak detection, helium mass spectrometry leak detection, mass production of vacuum vessels in the factory process, I feel inconvenient. We used in the production of the practice of H_2O as leakage of material vacuum gauge leak detection method. 1. Theoretical Basis It is well-known that the pressure in a vacuum vessel is determined by the difference between the gas leaked into the vessel per second and the gas drawn by the vacuum pump per second (with holes present and the wall excluded)
