two.LIQUID (WATER) RING VACUUM PUMPS
Working principle and functions:
To 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 from the casing types a liquid ring that is definitely concentric with the pump casing under the centrifugal effect, the cubage between liquid and vanes possess a periodic alter, so the function of pumping be carried out. Liquid ring vacuum pumps are in the characteristics of lower power consumption and very low noise. They can be utilized to pump water vapor, inflammable and explosive gasoline at the same time as ordinary gases. With exclusive supplies made use of for main elements, they’re able to also pump corrosive gasoline. Ideal actuating medium or sometimes pumped medium is usually selected as actuating liquids, so the pumps can virtually deal with all widely employed for light, chemical, food, electric power and pharmaceutical industries, and so forth.
