Helium mass spectrum leakage detection device for metal packaging container

Technical Field

The utility model relates to a helium mass spectrum leakage detection device for a metal packaging container.

Background

In the metal packaging container industry, the leakage rate requirements of different substances are different, and the leakage modes are different. There are two currently common leak detection methods: firstly, after the container is filled with a certain pressure (the filled material may be air or other gases), the container surface is coated with a solution or the container is placed in a water tank to observe the formation of bubbles, thereby judging the leakage condition. And secondly, filling the container to a certain pressure or placing the container in a vacuum box, vacuumizing the vacuum box and maintaining the pressure by using a sensor to judge the pressure change condition, thereby judging the leakage condition of the container. The two methods are easy to miss detection, long in detection time, easy to misjudge, low in detection precision and incapable of realizing data. Research on a leak detection device which has high detection precision, fast beat, data analysis capability, economy and practicability is imperative.
