Liquid Ring Vacuum Pump Working Theory. The vacuum pump consisting an impeller which is situated 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 usually starts move outward by centrifugal power.
Water ring vacuum pump is a common kind of liquid band vacuum pump. Water ring is usually a rotor with multi-blades eccentrically set up 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 Vacuum Pump drinking water Band 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 ring vacuum pump should be predicated on your on-site process, the required vacuum degree and the amount of air pumping required.
