two.LIQUID (WATER) RING VACUUM PUMPS
Working principle and characteristics:
For that 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 from the casing varieties a liquid ring that is concentric with the pump casing under the centrifugal impact, the cubage concerning liquid and vanes have a periodic change, so the function of pumping be carried out. Liquid ring vacuum pumps are on the features of low vitality consumption and very low noise. They are able to be employed to pump water vapor, inflammable and explosive gas likewise as ordinary gases. With exclusive elements applied for big components, they will also pump corrosive fuel. Suitable actuating medium or often pumped medium might be picked as actuating liquids, so the pumps can just about take care of all extensively used for light, chemical, foods, electric power and pharmaceutical industries, and so forth.
