2.LIQUID (WATER) RING VACUUM PUMPS
Operating principle and functions:
For the series SK, 2SK, YK and 2YK liquid ring vacuum pumps, multi-vane impeller is fixed ecceentrically while in the pump casing. When the vanes rotate, the liquid inside the casing kinds a liquid ring which is concentric with all the pump casing under the centrifugal effect, the cubage among liquid and vanes have a periodic adjust, so the function of pumping be performed. Liquid ring vacuum pumps are on the characteristics of reduced power consumption and lower noise. They might be applied to pump water vapor, inflammable and explosive gas also as ordinary gases. With unique supplies utilized for major parts, they are able to also pump corrosive gasoline. Suitable actuating medium or sometimes pumped medium could be chosen as actuating liquids, so the pumps can nearly handle all extensively used for light, chemical, foods, electrical energy and pharmaceutical industries, etc.
