Liquid Band Vacuum Pump Working Basic principle. The vacuum pump Water 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 definitely starts move outward by centrifugal pressure.
Water ring vacuum pump is a common kind of liquid ring vacuum pump. Water ring is usually 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 form a rotating variable capacity vacuum pump with periodic volume change. When the operating liquid is drinking water, it is called water Ring vacuum pump. There are numerous kinds of water ring vacuum pumps with different prices. .Among them, 2BV is more cost-effective. The type selection of water band vacuum pump ought to be based on your on-site procedure, the required vacuum level and the quantity of air pumping required.
