Liquid Ring Vacuum Pump Working Basic principle. The vacuum pump consisting an impeller which is located eccentric to the Water Vacuum Pump cylinder body(Vacuum pump housing). Vacuum is created in the vacuum pump by utilizing a liquid seal. … When the impeller begins to rotate, the liquid is begins move outward by centrifugal drive.
Water ring vacuum pump is a common kind of liquid ring vacuum pump. Water band is definitely a rotor with multi-blades eccentrically set up in the pump shell. When it rotates, it throws liquid in to the pump and forms a liquid ring concentric with the pump shell. The liquid band and the rotor blade form a rotating variable capability vacuum pump 
with periodic volume change. When the functioning liquid is drinking water, it is called water Ring vacuum pump. There are many kinds of water band vacuum pumps with different prices. .Included in this, 2BV is more cost-effective. The sort selection of water band vacuum pump ought to be based on your on-site process, the required vacuum degree and the amount of air pumping required.
