Description

Technical Field

[0001] The utility model relates to the technical field of water ring vacuum pumps, in particular to an energy-saving water ring vacuum pump. Background Art

[0002] Energy-saving water ring vacuum pump is a kind of high-efficiency and energy-saving vacuum equipment. Its working principle is mainly to use water as the working fluid, form a water ring through the rotation of the impeller, and then realize the suction, compression and discharge of gas. The design of energy-saving water ring vacuum pump focuses on improving energy efficiency, and achieves lower energy consumption and higher working efficiency by optimizing the impeller structure, reducing friction loss and other measures.

[0003] Existing water ring vacuum pumps, such as the one disclosed in publication number CN221195398U, have the advantage of preventing the fixing bolts from loosening, thereby making the water ring vacuum pump more stable in use. However, this water ring vacuum pump is not convenient for sufficient filtering and protection of the air intake and water intake during use, which makes it easy for dirt to accumulate on the upper end of the impeller of the water ring vacuum pump after long-term use. Therefore, we propose an energy-saving water ring vacuum pump. Utility Model Content
