Liquid Band Vacuum Pump Working Basic principle. The vacuum pump consisting an impeller which is located 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 usually begins move outward by centrifugal drive.
Water ring vacuum pump is a common kind of liquid band vacuum pump. Water ring is certainly a rotor with multi-blades Water Vacuum Pump eccentrically installed in the pump shell. When it rotates, it throws liquid into the pump and forms a liquid ring concentric with the pump shell. The liquid ring and the rotor blade type a rotating variable capability vacuum pump with periodic quantity change. When the operating liquid is drinking water, it is called drinking water Ring 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 ought to be based on your on-site process, the required vacuum degree and the amount of air pumping required.
