two.LIQUID (WATER) RING VACUUM PUMPS
Operating principle and features:
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 during the casing forms a liquid ring that is certainly concentric together with the pump casing under the centrifugal effect, the cubage between liquid and vanes possess a periodic adjust, so the perform of pumping be carried out. Liquid ring vacuum pumps are of your characteristics of minimal power consumption and low noise. They’re able to be employed to pump water vapor, inflammable and explosive fuel at the same time as ordinary gases. With exclusive resources used for main parts, they might also pump corrosive gasoline. Ideal actuating medium or sometimes pumped medium might be picked as actuating liquids, so the pumps can pretty much handle all extensively made use of for light, chemical, meals, electric electrical power and pharmaceutical industries, etc.
