2.LIQUID (WATER) RING VACUUM PUMPS
Working principle and functions:
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’s concentric together with the pump casing under the centrifugal effect, the cubage in between liquid and vanes have a periodic alter, so the function of pumping be carried out. Liquid ring vacuum pumps are of the attributes of reduced power consumption and very low noise. They will be employed to pump water vapor, inflammable and explosive gasoline as well as ordinary gases. With special resources applied for main parts, they might also pump corrosive gas. Ideal actuating medium or sometimes pumped medium is often picked as actuating liquids, so the pumps can almost deal with all broadly made use of for light, chemical, food, electrical power and pharmaceutical industries, and so forth.
