Analysis of the Factors Affecting the Speed of Helium Leak Detection and Discussion on the Method of Fast and Accurate Positioning

本文提出要实现氦检漏的快速精准定位,降低检漏成本,首先应讨论的几个方面的问题:检漏工作者的检漏任务、检漏的主要内容、对氦检漏人员的要求;如何利用检漏经验,快速精准判断泄漏产生的部位;提出了仪器的反应时间和清除时间、检漏仪灵敏度以及灵活、合理选择检漏方法是决定检漏速度重要因素。

In order to achieve rapid and accurate localizing and reduce the cost of leak detection,several aspects should be discussed first:Leak detection tasks of leak detecting workers,the main contents of leak detection and the requirements for crude personnel.How to use the leak detection experience to quickly and accurately determine the location of the leak.It is suggested that the reaction time and clearance time of the instrument,the sensitivity of the leak detector and the flexible and reasonable choice of the leak detection method are the important factors to determine the leak detection speed.
