Liquid Ring Water Vacuum Pump Vacuum Pump Working Theory. The vacuum pump consisting an impeller which is located 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 usually starts move outward by centrifugal push.
Water ring vacuum pump is a common kind of liquid ring vacuum pump. Water ring is definitely a rotor with multi-blades eccentrically installed 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 ring and the rotor blade form a rotating variable capability vacuum pump with periodic quantity change. When the working liquid is water, it is called drinking water Band vacuum pump. There are numerous 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 should be based on your on-site process, the required vacuum degree and the amount of air pumping required.
