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 in the pump casing. Once the vanes rotate, the liquid from the casing types a liquid ring which is concentric with the pump casing under the centrifugal impact, the cubage concerning liquid and vanes have a periodic transform, so the function of pumping be carried out. Liquid ring vacuum pumps are of your capabilities of lower power consumption and very low noise. They might be utilized to pump water vapor, inflammable and explosive fuel also as ordinary gases. With unique supplies employed for big elements, they are able to also pump corrosive gas. Appropriate actuating medium or in some cases pumped medium might be chosen as actuating liquids, so the pumps can virtually handle all widely utilised for light, chemical, foods, electric power and pharmaceutical industries, and so forth.
