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 created in the vacuum pump by using a liquid seal. … When the impeller starts to rotate, the liquid is starts move outward by centrifugal force.
Water ring vacuum pump is a common type of liquid ring vacuum pump. Water ring is a rotor with multi-blades eccentrically installed in the pump shell. When it rotates, it throws liquid into the pump and forms a liquid ring concentric with the pump shell. The liquid ring and the rotor blade form a rotating variable capacity vacuum pump with periodic volume change. When the working liquid is water, it is called water Ring vacuum pump. There are many kinds of water ring vacuum pumps with different prices. .Among them, 2BV is more cost-effective. The type selection of water ring vacuum pump should be based on your on-site process, the required vacuum degree and the amount of air pumping required.
