Vacuum pump, issue with lifting water level. Thank you
Thread Content
I would like to ask the experts: for this type of application, which of these three types of rotary vane vacuum pumps should be chosen? Which one can raise the water level inside the tank? Thank you. I don’t understand vacuum pumps; it’s just a rough sketch. Thank you for your help. Vacuum pump 1 ultimate vacuum: 6x10-2 Pa. Vacuum pump 2 ultimate vacuum: 0.067 Pa. Vacuum pump 3 ultimate pressure: 2 mbar
In the case of a water ring vacuum pump, all 3 options can be connected to the water tank, provided that the vacuum pump has a circulating water system
Is your jar airtight? Should the process factors inside the tank also be taken into consideration?
Any of them will work; for vacuum water transfer, a water ring is usually sufficient for 3–4 KW systems
Liquid cannot be drawn out from a sealed tank; an opening must be made to maintain atmospheric pressure
…………It’s possible to draw water up, but be careful as a square-shaped water tank might get flattened: lol
The inlet of the water tank must be at the top. The tank below needs to have a vent. The most important thing is that the vacuum level is fine, but there needs to be an evacuation rate; otherwise, the evacuation is too slow
