Pump Overview
2BEA series water ring vacuum pumps are of single stage and single acting configuration and are generally used for sucking gases that contains no solids,and are dissolved slightly or insoluble in working liquid.
When the wetted components of a vacuum pump are made of or coated with corrosion-free materials,it can suck corrosive gases or use corrosive liquids as it's working liquid.
Â
Figure 1 illustrates working principle of this vacuum pump.
The impeller is assembled eccentrically inside the nearly circular pump casing.When the impeller revolves in the direction indicated in Fig.1,the liquid is thrown outwards under centrifugal force to form a liquid ring.As a result,a crescent chamber area is developed between impeller hub and inner surface of the liquid ring.As rotation proceeds from point"A" to point"B",the chamber area between adjacement vanes will grow larger progressively,i.e.vacuum is set up and gas is drawn in via the inlet port.And as rotation proceeds from point "C" to point "A",the corressponding chamber will become smaller and smaller and the gas aspirated will be compressed.When the pressure reaches or is above outside pressure,it will be discharged through discharge port.
