Liquid Band Vacuum Pump Working 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 using a liquid seal. … When the impeller begins to rotate, the liquid is usually starts move outward by centrifugal force.
Water ring vacuum pump is a common kind of liquid band vacuum pump. Water ring is definitely a rotor with multi-blades eccentrically set up 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 capability vacuum pump with periodic volume change. When the working liquid is water, it is called drinking water Ring vacuum pump. There are numerous kinds of water band vacuum pumps with different prices. .Among them, 2BV is more cost-effective. The sort selection of water band vacuum pump ought to be predicated on your on-site procedure, the required vacuum degree and the Water Vacuum Pump quantity of air pumping required.
