Liquid Band Vacuum Pump Working Theory. The vacuum pump consisting an impeller which is located eccentric to the cylinder body(Vacuum pump housing). Vacuum is created in the vacuum pump by utilizing a liquid seal. … When the impeller begins to rotate, the liquid is Water Vacuum Pump definitely begins move outward by centrifugal push.
Water band vacuum pump is a common kind of liquid band vacuum pump. Water ring can be a rotor with multi-blades eccentrically installed 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 band and the rotor blade form a rotating variable capability vacuum pump with periodic volume change. When the operating liquid is water, it is called water Band vacuum pump. There are several kinds of water band vacuum pumps with different prices. .Included in this, 2BV is more cost-effective. The sort selection of water band vacuum pump should be predicated on your on-site procedure, the required vacuum degree and the quantity of air pumping required.
