Water Vacuum Pump 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 using a liquid seal. … When the impeller begins to rotate, the liquid is starts move outward by centrifugal pressure.
Water band vacuum pump is a common kind of liquid band vacuum pump. Water ring is 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 capability vacuum pump with periodic quantity change. When the operating liquid is drinking water, it is called drinking water Ring vacuum pump. There are several kinds of water ring vacuum pumps with different prices. .Included in this, 2BV is more cost-effective. The sort selection of water band vacuum pump ought to be based on your on-site procedure, the required vacuum degree and the amount of air pumping required.
