When the impeller rotates clockwise, water is thrown around by the impeller and forms a closed ring of approximately equal thickness depending on the shape of the pump chamber due to the centrifugal force. A moon-shaped space is formed between the impeller hub and the water ring, and the space is divided into a plurality of small cavities with the number equal to that of the blades by the impeller. In the air suction stage, the water ring is gradually far away from the hub, the volume of the small cavity is changed from small to large, and when the small cavity is communicated with the air suction port, air is sucked. In the exhaust stage, the water ring gradually approaches the hub, the small cavity is gradually reduced, so that the gas is compressed, and when the small cavity is communicated with the exhaust port, the gas is discharged out of the pump. With the stable rotation of the impeller, the air suction and exhaust processes are continuously carried out, so that the air can be continuously sucked.

When the water ring pump works, the water tank needs to continuously provide working water for the water ring pump, so the water tank has certain large volume and pressure to meet the working requirement, the space proportion of the whole working place occupied by the water tank is overlarge, and the space naturally reserved for other working parts is greatly reduced due to the limited volume of the working place. In view of the above circumstances, how to enlarge the working space of other components by reducing the volume of the water tank is an urgent problem to be solved in the field of research on the conventional water ring pump.

SUMMERY OF THE UTILITY MODEL
