China 2SK water ring vacuum pump

The China 2SK water ring vacuum pump is a coarse vacuum pump,equivalent to two SK series water ring vacuum pumps used in series.It is used to suck air and other non corrosive,insoluble,and solid particle free gases to achieve high vacuum in a closed container,forming a rotating water ring between the inner wall of the pump body and the impeller.The inner surface of the upper part of the water ring is in contact with the impeller hub.During the first half of the rotation of the impeller,the inner surface of the water ring gradually separates from the hub,and the cavity formed between adjacent blades gradually becomes larger.The extracted gas is sucked into the cavity;During the second half of the rotation,the inner surface of the water ring gradually approaches the hub,and the cavity between two adjacent blades gradually shrinks.The gas is compressed,and when the pressure increases to greater than the external pressure,the gas is discharged.

The pressure of China 2SK water ring vacuum pump usually refers to the high vacuum degree that the pump can achieve without external gas entering.According to different models and application scenarios,its pressure varies.Generally speaking,the pressure of a China 2SK water ring vacuum pump can reach 10-7 pascals.
This product is suitable for suctioning air and other non corrosive gases that do not contain solid particles.China's 2SK water ring vacuum pump is widely used in vacuum evaporation and concentration processes in the food and textile pharmaceutical industries.
