2.LIQUID (WATER) RING VACUUM PUMPS
Working principle and characteristics:
For your 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 while in the casing forms a liquid ring which is concentric using the pump casing beneath the centrifugal effect, the cubage in between liquid and vanes possess a periodic modify, so the function of pumping be performed. Liquid ring vacuum pumps are with the functions of very low vitality consumption and minimal noise. They are able to be applied to pump water vapor, inflammable and explosive gasoline also as ordinary gases. With specific elements employed for main parts, they are able to also pump corrosive fuel. Ideal actuating medium or occasionally pumped medium is often chosen as actuating liquids, so the pumps can just about handle all extensively applied for light, chemical, meals, electric energy and pharmaceutical industries, and so forth.
