Energy-saving issues in the modification of liquid ring vacuum pumps
Thread Content
There is currently a vacuum pump whose pumping capacity is 1/3 higher than what the system requires, resulting in underutilization of this equipment. Can power consumption be reduced by increasing the frequency conversion or replacing it with a low-power motor?
Sure, I once replaced a small motor with a larger one; it was the opposite of what the original poster did
It’s possible, but the speed of a liquid ring pump generally falls within a certain range; if the pump in question is already operating at a low speed, then it’s not feasible Any lower and a liquid ring cannot be formed!
A lower power rating of the motor has no direct relationship with the pumping volume; if it’s too low, it may not be able to handle the workload.
No! Burn the motor! A low rotational speed prevents the formation of a liquid ring.
The question is how you define a large increase of 1/3? Changing the frequency is feasible, but replacing it with a motor of lower power is not!
