2.LIQUID (WATER) RING VACUUM PUMPS
Working principle and characteristics:
To the series SK, 2SK, YK and 2YK liquid ring vacuum pumps, multi-vane impeller is fixed ecceentrically from the pump casing. Once the vanes rotate, the liquid 
from the casing forms a liquid ring which is concentric using the pump casing under the centrifugal effect, the cubage in between liquid and vanes possess a periodic adjust, so the perform of pumping be carried out. Liquid ring vacuum pumps are of the functions of reduced vitality consumption and minimal noise. They could be made use of to pump water vapor, inflammable and explosive gasoline at the same time as ordinary gases. With distinctive elements utilised for big parts, they are able to also pump corrosive fuel. Ideal actuating medium or occasionally pumped medium is often chosen as actuating liquids, so the pumps can just about handle all extensively used for light, chemical, meals, electrical energy and pharmaceutical industries, and so forth.
