2.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 from the pump casing. When the vanes rotate, the liquid in the casing forms a liquid ring which is concentric with the pump casing under the centrifugal impact, the cubage amongst liquid and vanes have a periodic alter, so the function of pumping be carried out. Liquid ring vacuum pumps are from the capabilities of lower energy consumption and very low noise. They are able to be made use of to pump water vapor, inflammable and explosive gas too as ordinary gases. With special supplies used for main components, they might also pump corrosive gas. Ideal actuating medium or often pumped medium might be picked as actuating liquids, so the pumps can almost deal with all broadly utilised for light, chemical, foods, electric power and pharmaceutical industries, and so on.
