two.LIQUID (WATER) RING VACUUM PUMPS
Working principle and attributes:
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 inside the casing varieties a liquid ring that is certainly concentric using the pump casing under the centrifugal result, the cubage in between liquid and vanes have a periodic transform, so the function of pumping be performed. Liquid ring vacuum pumps are of the features of very low vitality consumption and reduced noise. They could be applied to pump water vapor, inflammable and explosive gas at the same time as ordinary gases. With unique elements used for significant parts, they can also pump corrosive fuel. Suitable actuating medium or occasionally pumped medium might be chosen as actuating liquids, so the pumps can practically manage all extensively applied for light, chemical, food, electric energy and pharmaceutical industries, and so on.
