[0002] Axial mixed flow pump is a pump between centrifugal pump and axial flow pump. Its working principle and characteristics combine the characteristics of centrifugal pump and axial flow pump. The shape of the impeller of axial mixed flow pump is between the impeller of centrifugal pump and the impeller of axial flow pump. Therefore, its working principle has both centrifugal force and lift. By the combined effect of the two, water flows out of the impeller at a certain angle with the shaft, and the water is lifted to a higher place through the volute chamber and pipeline. Axial mixed flow pump can be used not only in urban water supply and drainage systems, but also in farmland irrigation, industrial cooling water circulation and other fields;
