two.LIQUID (WATER) RING VACUUM PUMPS
Operating principle and options:
To 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 from the casing varieties a liquid ring that is certainly concentric with all the pump casing under the centrifugal effect, the cubage among liquid and vanes have a periodic modify, so the function of pumping be performed. Liquid ring vacuum pumps are with the features of very low vitality consumption and lower noise. They can be made use of to pump water vapor, inflammable and explosive gasoline as well as ordinary gases. With unique components utilized for key elements, they might also pump corrosive gas. Suitable actuating medium or often pumped medium is usually selected as actuating liquids, so the pumps can almost deal with all widely utilized for light, chemical, meals, electrical energy and pharmaceutical industries, etc.
