Vacuum system leakage estimation
Thread Content
I want to choose a vacuum pump, but I don’t know how to consider the leakage of the vacuum system. The chemical process design gives a particularly good 0.03kg/hm, a good 0.1kg/hm, and generally 0.2kg/hm. Is it relatively large? Our device is relatively small and only has a few DN100 flanges on the seal. Do we need to consider such a large air leakage? Please enlighten us!

Haha, the poster can figure it out. . . If your maintenance workers can maintain the device "exceptionally well", then you can go straight to "exceptionally well". . . :)
Look at the degree of vacuum. The higher the degree of vacuum, the easier it is to leak. However, there is actually no specific data. You can refer to old devices or other similar working conditions to make your selection.
