two.LIQUID (WATER) RING VACUUM PUMPS
Operating principle and capabilities:
To the series SK, 2SK, YK and 2YK liquid ring vacuum pumps, multi-vane impeller is fixed ecceentrically inside the pump casing. When the vanes rotate, the liquid from the casing forms a liquid ring which is concentric with all the pump casing under the centrifugal impact, the cubage in between liquid and vanes have a periodic transform, so the perform of pumping be carried out. Liquid ring vacuum pumps are on the options of very low energy consumption and lower noise. They can be utilized to pump water vapor, inflammable and explosive gas too as ordinary gases. With particular elements used for significant components, they could also pump corrosive gasoline. Suitable actuating medium or occasionally pumped medium is often chosen as actuating liquids, so the pumps can virtually deal with all widely applied for light, chemical, foods, electrical electrical power and pharmaceutical industries, and so forth.
