two.LIQUID (WATER) RING VACUUM PUMPS
Operating principle and attributes:
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 within the casing varieties a liquid ring which is concentric using the pump casing under the centrifugal impact, the cubage among liquid and vanes have a periodic modify, so the perform of pumping be performed. Liquid ring vacuum pumps are in the features of very low power consumption and lower noise. They can be utilized to pump water vapor, inflammable and explosive fuel also as ordinary gases. With special materials utilised for main parts, they are able to also pump corrosive gasoline. Appropriate actuating medium or in some cases pumped medium could be picked as actuating liquids, so the pumps can pretty much take care of all widely used for light, chemical, meals, electrical electrical power and pharmaceutical industries, etc.
