2.LIQUID (WATER) RING VACUUM PUMPS
Operating principle and capabilities:
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 during the casing varieties a liquid ring that’s concentric using the pump casing under the centrifugal effect, the cubage amongst liquid and vanes possess a periodic transform, so the function of pumping be performed. Liquid ring vacuum pumps are from the characteristics of low energy consumption and minimal noise. They’re able to be used to pump water vapor, inflammable and explosive gasoline likewise as ordinary gases. With distinctive components utilised for big parts, they will also pump corrosive gas. Ideal actuating medium or sometimes pumped medium might be chosen as actuating liquids, so the pumps can nearly handle all extensively utilized for light, chemical, foods, electric energy and pharmaceutical industries, and so forth.
