two.LIQUID (WATER) RING VACUUM PUMPS
Working principle and functions:
For that series SK, 2SK, YK and 2YK liquid ring vacuum pumps, multi-vane impeller is fixed ecceentrically inside the pump casing. When the vanes rotate, the liquid in 
the casing kinds a liquid ring which is concentric together with the pump casing beneath the centrifugal impact, the cubage involving liquid and vanes possess a periodic adjust, so the perform of pumping be performed. Liquid ring vacuum pumps are in the options of low energy consumption and very low noise. They are able to be applied to pump water vapor, inflammable and explosive gas at the same time as ordinary gases. With distinctive resources utilised for main elements, they will also pump corrosive gas. Ideal actuating medium or sometimes pumped medium may be chosen as actuating liquids, so the pumps can virtually manage all broadly used for light, chemical, food, electric electrical power and pharmaceutical industries, and so on.
