two.LIQUID (WATER) RING VACUUM PUMPS
Working principle and characteristics:
For the series SK, 2SK, YK and 2YK liquid ring vacuum pumps, multi-vane impeller is fixed ecceentrically while in the pump casing. Once the vanes rotate, the liquid during the casing varieties a liquid ring that is certainly concentric together with the pump casing under the centrifugal effect, the cubage involving liquid and vanes possess a periodic alter, so the perform of pumping be performed. Liquid ring vacuum pumps are with the attributes of minimal energy consumption and minimal noise. They will be utilised to pump water vapor, inflammable and explosive gas at the same time as ordinary gases. With special elements used for major parts, they are able to also pump corrosive gasoline. Ideal actuating medium or sometimes pumped medium can be chosen as actuating liquids, so the pumps can just about manage all widely utilized for light, chemical, foods, electrical power and pharmaceutical industries, and so on.
