Does the water ring vacuum pump need to be filled with water?
Thread Content
The water ring vacuum pump uses a water ring to drive the pump to rotate. After the pump stops running, does the inlet still need to be filled with water? If water is not filled, will the pump empty out? I’m not sure, please let an expert explain, thank you, extra points
The water cannot be lost. There is a liquid level control. It depends on what is being pumped. Generally, the pumped medium contains water, but it needs to be drained.
What kind of water should be added when the pump is stopped? Anti-rust?

Instead, the impeller is installed eccentrically in the pump body (also divided into upper eccentricity and lower eccentricity, cone body intake and exhaust or flat disk intake and exhaust). After the motor drives the impeller to rotate, the liquid will centrifugally form a liquid ring that is the same shape as the pump body, and then rely on the sealing of the two adjacent impellers and water rings to expand and contract the volume with rotation... Stop water inflow after shutdown. If it is a closed circulation system, the water level will stop at the center line of the pump.……
”A water ring vacuum pump uses a water ring to drive the pump to rotate "", this sentence is wrong. The water ring vacuum pump contains an appropriate amount of water as the working fluid in the pump body. The water is thrown around by the impeller. Due to the centrifugal force, the water forms a closed ring of approximately equal thickness determined by the shape of the pump chamber. “After the pump stops running, does the inlet still need to be filled with water? If you don’t fill it with water, will the pump be empty?” After the pump stops working, of course it will not be pumped out, and there is no need to fill it with water.
Of course you need it, you can look at this manual
If there is water in the pump chamber, there is no need to add water. If there is no water in the pump body, water must be added. Generally, water needs to be added when used for the first time. When it is stopped and used again, there is usually water in the pump chamber, so there is no need to add water.
Required for initial startup, no emptying after shutdown, no water filling required later.
Water needs to be added during initial work. In the later stage, the working water may evaporate with the medium. Therefore, water must be replenished based on the actual liquid level in the pump.
Just started to enter the vacuum pump industry, learn* study * :lol
There is no need to add water after shutdown. The general operation is to stop the water supply valve first, then close the inlet valve, and generally open the drain valve to drain the water out of the pump body to prevent the pump body from being overloaded with water and making it difficult to open the pump next time.
