§1-1 概述容器泄漏检测是无损检测的一种。人们最早是用盛水法检查容器的泄漏。四十年代以前,只有简单的几种检漏方法,当时最高灵敏度为10~(-5)～10~(-6)托·升/秒。四十年代以后,将质谱技术应用于检漏,才使检漏技术有了重大突破。目前,虽然氦质谱检漏仪的灵敏度达到10~(-13)托、升/秒,但并非是万能的。至今为止,检漏方法已达近六十种,它们各有各的长处。检漏技术对于真空容器来说,其重要性是十分明显的,对受压容器的制造和检修,也是一种重要的手段。
§1-1 Overview Container leak detection is a non-destructive testing. People first use the water method to check the container leakage. Before the forties, only a few simple leak detection method, the highest sensitivity of 10 ~ (-5) ~ 10 ~ (-6) Torr / liter. After the forties, mass spectrometry technology used in leak detection, leak detection technology has made a major breakthrough. At present, although the helium mass spectrometer leak detector sensitivity of 10 ~ (-13) care, liters / second, but not a panacea. So far, the leak detection method has reached nearly 60, they each have their own strengths. Leak detection technology for vacuum containers, its importance is very obvious, the pressure vessel manufacturing and maintenance, but also an important means.
