SK series water ring vacuum pumps and compressors are used to pump or compress air and other non-corrosive, water-insoluble, solid particles-free gases to create vacuum and pressure in a closed container. liquid. SK direct water ring vacuum pumps and compressors are widely used in machinery, petrochemical, pharmaceutical, food, sugar industry and electronics. Since the compression process of the gas is isothermal during the working process, it is less prone to danger when compressing and pumping the explosive gas, so its application is more extensive.
Note: The values in the table are obtained under the following conditions: 1 water temperature 15 ° C; 2 air 20 ° C; 3 gas relative temperature 70%
As shown in (1), the impeller is eccentrically installed in the pump body. When the pump is started, a certain height of water is injected into the pump. When the impeller rotates, the water is subjected to centrifugal force to form a rotating water ring on the inner wall of the pump body. When the inner surface of the lower part of the water ring is tangent to the hub and rotates in the direction of the arrow, the inner surface of the water ring is gradually separated from the hub during the first half turn, so that a space is formed between the blades and gradually enlarged, and the internal pressure is lower than the pressure at the inlet. Inhale gas. During the second half turn, the inner surface of the water ring gradually approaches the hub, and the space between the blades is reduced, and the gas pressure is discharged when it is higher than the atmospheric pressure. When the impeller is operated repeatedly, the pump continuously draws gas.
Since water will heat up with the continuation of working time during the working process, some water will be discharged together with the gas. Therefore, cold water should be continuously supplied to the pump during the work to cool and replenish the water consumed in the pump.
