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 from the pump casing. When the vanes rotate, the liquid in the casing types a liquid ring which is concentric using the pump casing under the centrifugal result, the cubage among liquid and vanes possess a periodic adjust, so the perform of pumping be performed. Liquid ring vacuum pumps are with the characteristics of reduced power consumption and very low noise. They could be utilised to pump water vapor, inflammable and explosive gas likewise as ordinary gases. With specific products utilized for main parts, they’re able to also pump corrosive gas. Suitable actuating medium or from time to time pumped medium might be selected as actuating liquids, so the pumps can virtually manage all extensively used for light, chemical, meals, electrical power and pharmaceutical industries, etc.
