Liquid Ring Water Vacuum Pump Vacuum Pump Working Theory. The vacuum pump consisting an impeller which is situated 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 starts move outward by centrifugal power.
Water ring vacuum pump is a common type of liquid ring vacuum pump. Water band is definitely a rotor with multi-blades eccentrically set up 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 type a rotating variable capacity vacuum pump with periodic volume change. When the operating liquid is drinking water, it is called drinking water Ring vacuum pump. There are several kinds of water ring vacuum pumps with different prices. .Included in this, 2BV is more cost-effective. The type selection of water band vacuum pump ought to be based on your on-site process, the required vacuum degree and the quantity of air pumping required.
