Water Vacuum Pump 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 established in the vacuum pump by utilizing a liquid seal. … When the impeller begins to rotate, the liquid is usually starts move outward by centrifugal force.
Water ring vacuum pump is a common type of liquid band vacuum pump. Water band is certainly 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 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 water, it is called drinking 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 ring vacuum pump should be predicated on your on-site process, the required vacuum degree and the quantity of air pumping required.
