2.LIQUID (WATER) RING VACUUM PUMPS
Operating principle and characteristics:
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 within the casing forms a liquid ring that is definitely concentric together with the pump casing under the centrifugal impact, the cubage between liquid and vanes possess a periodic change, so the function of pumping be carried out. Liquid ring vacuum pumps are in the functions of reduced power consumption and minimal noise. They can be applied to pump water vapor, inflammable and explosive fuel as well as ordinary gases. With distinctive supplies employed for key elements, they might also pump corrosive gas. Appropriate actuating medium or occasionally pumped medium is often chosen as actuating liquids, so the pumps can just about take care of all widely employed for light, chemical, food, electrical electrical power and pharmaceutical industries, and so forth.
