9. When the diffusion pump is working normally, if the vacuum gauge tube of the vacuum system is broken, or when the vent valve suddenly opens, the high vacuum valve should be closed immediately. Prevent oxidation of pump oil. 10. when the diffusion pump is stopped, it should be kept in vacuum and cooled by compressed air.

Backstreaming

Backstreaming

Jan 08, 2013 · In simplest terms, backstreaming is the movement of pumping fluid back into the vacuum furnace chamber, that is, oil vapor molecules attempt to reverse course and move up and back toward the vacuum vessel, opposite to the direction of the desired gas flow. Backstreaming is not limited to the pumps themselves, but encompass the entire pumping system .
