2.LIQUID (WATER) RING VACUUM PUMPS
Operating principle and options:
For the series SK, 2SK, YK and 2YK liquid ring vacuum pumps, multi-vane impeller is fixed ecceentrically during the pump casing. When the vanes rotate, the liquid within the casing kinds a liquid ring that may be concentric together with the pump casing under the centrifugal effect, the cubage in between liquid and vanes possess a periodic change, so the function of pumping be carried out. Liquid ring vacuum pumps are from the features of very low power consumption and lower noise. They will be utilised to pump water vapor, inflammable and explosive fuel too as ordinary gases. With particular components used for significant parts, they could also pump corrosive fuel. Ideal actuating medium or often pumped medium can be selected as actuating liquids, so the pumps can nearly take care of all extensively utilised for light, chemical, foods, electrical energy and pharmaceutical industries, and so forth.
