two.LIQUID (WATER) RING VACUUM PUMPS
Operating principle and attributes:
To the series SK, 2SK, YK and 2YK liquid ring vacuum pumps, multi-vane impeller is fixed ecceentrically inside the pump casing. Once the vanes rotate, the liquid in the casing forms a liquid ring that is certainly concentric with all the pump casing under the centrifugal impact, the cubage involving liquid and vanes possess a periodic adjust, so the function of pumping be performed. Liquid ring vacuum pumps are in the functions of minimal vitality consumption and low noise. They are able to be made use of to pump water vapor, inflammable and explosive gas as well as ordinary gases. With particular 
components utilised for main elements, they can also pump corrosive fuel. Ideal actuating medium or occasionally pumped medium could be picked as actuating liquids, so the pumps can nearly deal with all broadly utilised for light, chemical, food, electrical power and pharmaceutical industries, etc.
