Liquid Ring Water Vacuum Pump vacuum Pump Working Basic principle. The vacuum pump consisting an impeller which is located eccentric to the cylinder body(Vacuum pump casing). Vacuum is created in the vacuum pump by using a liquid seal. … When the impeller starts to rotate, the liquid is usually begins move outward by centrifugal pressure.
Water band vacuum pump is a common kind of liquid ring vacuum pump. Water ring can be a rotor with multi-blades eccentrically installed in the pump shell. When it rotates, it throws liquid into the pump and forms a liquid band 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 functioning liquid is water, it is called drinking water Ring vacuum pump. There are numerous kinds of water band vacuum pumps with different prices. .Among them, 2BV is more cost-effective. The type selection of water ring vacuum pump ought to be based on your on-site process, the required vacuum degree and the quantity of air pumping required.
