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 utilizing a liquid seal. … When the impeller starts to rotate, the liquid is begins move outward by centrifugal drive.
Water band vacuum pump is a common type of liquid band vacuum pump. Water band is a rotor with multi-blades eccentrically 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 ring and the rotor blade type a rotating Water Vacuum Pump variable capacity vacuum pump with periodic quantity change. When the working liquid is drinking water, it is called water Ring vacuum pump. There are many kinds of water band vacuum pumps with different prices. .Among them, 2BV is more cost-effective. The type selection of water band vacuum pump should be based on your on-site process, the required vacuum degree and the quantity of air pumping required.
