two.LIQUID (WATER) RING VACUUM PUMPS
Operating principle and characteristics:
For that 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 during the casing varieties a liquid ring that is concentric with the pump casing beneath the centrifugal effect, the cubage among liquid and vanes possess a periodic modify, so the perform of pumping be performed. Liquid ring vacuum pumps are of the functions of minimal power consumption and low noise. They will be utilized to pump water vapor, inflammable and explosive gasoline also as ordinary gases. With particular elements made use of for big parts, they are able to also pump corrosive gas. Suitable actuating medium or occasionally pumped medium is usually picked as actuating liquids, so the pumps can pretty much manage all widely applied for light, chemical, food, electric power and pharmaceutical industries, etc.
