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. Once the vanes rotate, the liquid within the casing forms a liquid ring that may be concentric with all the pump casing under the centrifugal impact, the cubage concerning liquid and vanes have a periodic transform, so the function of pumping be carried out. Liquid ring vacuum pumps are of your functions of reduced energy consumption and low noise. They’re able to be employed to pump water vapor, inflammable and explosive fuel also as ordinary gases. With exclusive elements applied for important parts, they are able to also pump corrosive fuel. Ideal actuating medium or in some cases pumped medium can be chosen as actuating liquids, so the pumps can practically take care of all widely utilised for light, chemical, foods, electrical electrical power and pharmaceutical industries, etc.
