two.LIQUID (WATER) RING VACUUM PUMPS
Working principle and options:
For the series SK, 2SK, YK and 2YK liquid ring vacuum pumps, multi-vane impeller is fixed ecceentrically in the pump casing. When the vanes rotate, the liquid during the casing varieties a liquid ring that is concentric with the pump casing under the centrifugal result, the cubage between liquid and vanes have a periodic adjust, so the function of pumping be performed. Liquid ring vacuum pumps are with the functions of minimal power consumption and minimal noise. They could be employed to pump water vapor, inflammable and explosive gas also as ordinary gases. With distinctive supplies utilized for key components, they could also pump corrosive gasoline. Ideal actuating medium or occasionally pumped 
medium can be picked as actuating liquids, so the pumps can virtually deal with all broadly employed for light, chemical, meals, electrical electrical power and pharmaceutical industries, and so on.
