2.LIQUID (WATER) RING VACUUM PUMPS
Working principle and functions:
For your series SK, 2SK, YK and 2YK liquid ring vacuum pumps, multi-vane impeller is fixed ecceentrically within the pump casing. Once the vanes rotate, the liquid while in the casing forms a liquid ring that is definitely concentric together with the pump casing under the centrifugal result, the cubage in between liquid and vanes have a periodic modify, so the perform of pumping be carried out. Liquid ring vacuum pumps are of the characteristics of reduced vitality consumption and low noise. They will be made use of to pump water vapor, inflammable and explosive gas also as ordinary gases. With special elements applied for big components, they will also pump corrosive gasoline. Appropriate actuating medium or at times pumped medium can be selected as actuating liquids, so the pumps can nearly manage all broadly applied for light, chemical, meals, electric energy and pharmaceutical industries, etc.
