Problems with water ring vacuum pumps
Thread Content
For the condensation at the top of the distillation tower, evaporation cooling is used; after that, a water-ring vacuum pump is employed. Why, when this pump is started, does the liquid separation process not result in liquid being discharged downward, but instead water flows upward?
The negative pressure is too high, resulting in a high water column being lifted
Well, after thinking about it, I guess it was probably drawn in by negative pressure
Is the vacuum level above the required value? Reducing the negative pressure will solve the problem! :)
When the vacuum level is high, and provided that the process requirements permit it, the air-cooling load can be reduced
