Water ring vacuum pump can pump?

The water ring vacuum pump is an impeller with vanes eccentrically mounted in a water-filled pump housing. The impeller rotates in the pump housing to form a water ring. Its function is equivalent to a piston, and a vacuum pump that draws out air to form a vacuum by changing the volume. This shows that the water ring vacuum pump is to remove gas, not liquid. If the water-ring pump is used as the liquid conveying mechanism, the liquid in the water ring pump cavity cannot be promptly excluded from the pump, resulting in excessive pressure in the pump cavity, causing motor overload, motor phase loss, exhaust obstruction, and impeller dragging. part.

If a water ring pump is required to remove the water vapor and water during the actual operation, a pre-separator is required between the water ring pump and the heat exchanger to separate the gas and water, and then to achieve vacuum suction. the goal of. Therefore, the water ring vacuum pump cannot be used alone to pump water.
