2.LIQUID (WATER) RING VACUUM PUMPS
Operating principle and attributes:
For 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 that is definitely concentric together with the pump casing beneath the centrifugal result, the cubage between liquid and vanes have a periodic adjust, so the perform of pumping be carried out. Liquid ring vacuum pumps are of the features of minimal vitality consumption and reduced noise. They could be used to pump water vapor, inflammable and explosive fuel at the same time as ordinary gases. With unique components employed for main components, they are able to also pump corrosive gas. Suitable actuating medium or in some cases pumped medium can be chosen as actuating liquids, so the pumps can virtually deal with all extensively employed for light, chemical, foods, electric electrical power and pharmaceutical industries, and so forth.
