Liquid Band Vacuum Pump Working Principle. The vacuum pump consisting an impeller which is situated eccentric to the cylinder body(Vacuum pump casing). Vacuum is established in the vacuum pump by using a liquid seal. … When the impeller begins to rotate, the liquid is definitely begins move outward by centrifugal pressure.
Water ring vacuum pump is a common type of liquid band vacuum pump. Water band is certainly 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 type a rotating variable capacity vacuum pump with periodic Water Vacuum Pump quantity change. When the functioning liquid is water, it is called drinking water Band vacuum pump. There are numerous kinds of water band 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 procedure, the required vacuum level and the amount of air pumping required.
