Liquid Ring Vacuum Pump Working Theory. 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 starts to rotate, the liquid is certainly begins move outward by centrifugal power.
Water band vacuum pump is a Water Vacuum Pump common kind of liquid ring vacuum pump. Water ring is definitely 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 ring and the rotor blade form a rotating variable capability vacuum pump with periodic quantity change. When the operating liquid is drinking water, it is called water Ring vacuum pump. There are many kinds of water band 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 process, the required vacuum degree and the quantity of air pumping required.
