Study on Double Vacuum Leak Detection Technology of Lyophilizer Shelf

Core Tips: After the main components of the lyophilizer are processed, they should be leak-checked separately, with obvious leaks and leaks removed, and the initial inspection of the components completed, but often not enough. It is also necessary to repeat the assembly and assembly process. Careful and meticulous leak detection, found that problems were eliminated in a timely manner, leaving no hidden dangers. In the whole assembly and debugging

After the main components of the lyophilization machine are processed, they should be leak-checked separately, obvious leaks and leaks should be removed, and the initial inspection of the components should be completed, but this is often not enough. It also requires careful and careful attention during assembly and assembly. Leak detection, found that the problem was eliminated in a timely manner, leaving no hidden trouble. In the process of assembly and debugging of the whole machine, it is inevitable that some unimaginable problems will be exposed. This article summarizes from practice, the use of double vacuum leak detection method is an effective method, easy to get twice the result with half the effort.

Anti-corrosion refers to the protection of metal surfaces from corroding in high-risk (corrosive) environments.
When metallic materials are put into corrosive environments, they tend to have chemical reactions with the air and/or water. The effects of corrosion become evident on the surfaces of these materials. For example, after putting a piece of iron into a corrosive atmosphere for an extended period, it starts rusting due to oxygen interaction with water on the surface of the piece of iron.
