Liquid Band Vacuum Pump Working Principle. The vacuum pump consisting an impeller which is located eccentric to the cylinder body(Vacuum pump casing). Vacuum is established in the vacuum pump by utilizing a liquid seal. … When the impeller begins to rotate, the liquid is starts move outward by centrifugal push.
Water ring vacuum pump is a common type of liquid ring vacuum pump. Water band is certainly a rotor with multi-blades eccentrically Water Vacuum Pump installed in the pump shell. When it rotates, it throws liquid in to 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 working liquid is water, it is called water Ring vacuum pump. There are various kinds of water band vacuum pumps with different prices. .Included in this, 2BV is more cost-effective. The type selection of water ring vacuum pump ought to be based on your on-site procedure, the required vacuum degree and the quantity of air pumping required.
