Mixed-flow pump definition

The use of centrifugal force generated by the impeller rotation and thrust joint work, oblique outflow, also known as ramp pump, a scroll (horizontal) and guide vane (vertical) two. It combines the advantages of centrifugal pump and axial flow pump, simple structure, high efficiency area, easy to use, suitable for plain polder farmland irrigation and pumping station. China developed mixed flow pump, volute-type lift 5 ~ 12m, flow 900 ~ 4000m3 / h; guide vane lift 3 ~ 25.7m, flow 45 ~ 20160m3 / h. Suqian County, Jiangsu Province, soap River pump station installed two guide vane pump. Impeller diameter 5.7m, flow 80 ~ 100m3 / s, lift 6 ~ 12m, speed 75r / min, the maximum efficiency of 92.1%, supporting power 7000kW, is the world put into operation one of the large-scale mixed flow pump. Mixed flow pump is the international pump industry, one of the key technology development. It will partially replace the centrifugal pump and axial pump work. In Japan, the Soviet Union, Australia and other countries, the maximum efficiency of Francis pumps have reached or exceeded 90%.
