2.LIQUID (WATER) RING VACUUM PUMPS
Operating principle and features:
To the series SK, 2SK, YK and 2YK liquid ring vacuum pumps, multi-vane impeller is fixed ecceentrically during the pump casing. Once the vanes rotate, the liquid inside the casing forms a liquid ring that is concentric with all the pump casing under the centrifugal effect, the cubage among liquid and vanes have a periodic change, so the function of pumping be carried out. Liquid ring vacuum pumps are with the attributes of minimal vitality consumption and reduced noise. They could be utilized to pump water vapor, inflammable and explosive fuel as well as ordinary gases. With specific materials utilized for major components, they are able to also pump corrosive gasoline. Suitable actuating medium or at times pumped medium might be selected as actuating liquids, so the pumps can just about handle all extensively utilised for light, chemical, meals, electrical power and pharmaceutical industries, etc.
