Liquid Band Vacuum Pump Water Vacuum Pump working Basic principle. The vacuum pump consisting an impeller which is located eccentric to the cylinder body(Vacuum pump casing). Vacuum is created in the vacuum pump by utilizing a liquid seal. … When the impeller starts to rotate, the liquid is definitely begins move outward by centrifugal drive.
Water band vacuum pump is a common type 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 into the pump and forms a liquid band concentric with the pump shell. The liquid ring and the rotor blade type a rotating variable capacity vacuum pump with periodic quantity change. When the working liquid is water, it is called water Ring vacuum pump. There are various kinds of water ring vacuum pumps with different prices. .Included in this, 2BV is more cost-effective. The type
