From the principle of work, after the prime mover to drive the impeller rotation, to the effect of liquid there are both centrifugal and axial thrust, is a combination of centrifugal pumps and axial flow pump. So it is a pump between centrifugal pumps and axial flow pump. Mixed flow pump specific speed centrifugal pump prep above, below the axial flow pump, generally between 300-500. Its head is higher than axial flow pump, but lower than the centrifugal pump flow is smaller than axial flow pump, is bigger than a centrifugal pump.
Mixed flow pump are both axial and radial synthesis with the impeller rotating center into an oblique Angle. Under the same flow, axial flow pump head is lower than mixed flow pump. May be expensive because of axial flow pump is vertical, and that cheap mixed flow pump may be horizontal volute (because the flow rate of 1 m3 / S or 3600 m3 / h, is very small for axial flow mixed flow pump, mixed-flow pump, therefore, may be horizontal volute.
weihu mixed flow pump with centrifugal pump and the advantages of axial flow pump, simple structure, high efficient area wide, easy to use, apply to the original embankment areas of farmland irrigation and drainage pumping station. China's development of the mixed flow pump, head of volute 5 ~ 12 m, flow rate of 900 ~ 4000 m3 / h. Guide vane lift 3 ~ 25.7 m, traffic 45 ~ 20160 m3 / h.
