Liquid Ring Vacuum Pump Working Theory. 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 certainly starts move outward by centrifugal push.
Water ring vacuum pump is a common type of liquid band vacuum pump. Water band is usually 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 band and the rotor blade type 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 various kinds of water band vacuum pumps with Water Vacuum Pump different prices. .Among them, 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.
