Water Vacuum Pump liquid Ring Vacuum Pump Working Principle. The vacuum pump consisting an impeller which is located eccentric to the cylinder body(Vacuum pump housing). Vacuum is established in the vacuum pump by utilizing a liquid seal. … When the impeller starts to rotate, the liquid is certainly begins move outward by centrifugal pressure.

Water band vacuum pump is a common kind of liquid ring vacuum pump. Water band is 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 capacity vacuum pump with periodic volume change. When the operating liquid is drinking water, it is called water Band vacuum pump. There are several kinds of water ring vacuum pumps with different prices. .Included in this, 2BV is more cost-effective. The type selection of water ring vacuum pump ought to be predicated on your on-site procedure, the required vacuum degree and the amount of air pumping required.
