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 housing). Vacuum is created in the vacuum pump by utilizing a liquid seal. … When the impeller begins to rotate, the liquid is certainly starts move outward by centrifugal force.
Water band vacuum pump is a common kind of liquid ring vacuum pump. Water band is 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 ring concentric with the pump shell. The liquid band and the rotor blade type a rotating variable capability vacuum pump with periodic quantity change. When the working liquid is water, it is called water Band vacuum pump. There are many kinds of water ring vacuum pumps with different prices. .Among them, 2BV is more cost-effective. The sort selection of water band vacuum pump should be predicated on your on-site process, the required vacuum degree and the quantity of air pumping required.
