Select the vacuum pump based on the available time for evacuation
Thread Content
As the title suggests, I’m starting this thread for discussion. In the stage of rough vacuum, the vacuum pump should be selected based on the evacuation time. If it’s a sealed container that needs to be evacuated, the formula T=2.3VLG(P1/P2)/Q can be used for a preliminary selection. However, if the container is not sealed but rather a pre-buffer tank, with the material flowing into the tank at a certain volume flow rate before entering the vacuum pump through pipes, then if the customer still requires that the pressure reach the desired level within a specific time frame, how should the pumping speed of the pump be calculated initially? I would appreciate guidance from experts on this forum; let’s learn from each other. Thank you.
This problem is too complicated; I’m not in the right mood today to focus.
Generally, for a sealed tank that is to be evacuated, formulas can be used to carry out a preliminary selection. But what if material continues to flow into the tank? How should such a situation be calculated? Please advise
