Francis pump works, English as: Mixed flow pump driven by the prime mover when the impeller rotates, centrifugal force to effect fluid both axial thrust there is a comprehensive 350HW-8 mixed centrifugal and axial flow pumps, the liquid obliquely outflow impeller. So it is between a centrifugal and axial flow pump between. Francis higher specific speed centrifugal pump is lower than the pump, generally between 300-500. Its head is higher than the axial flow pump, axial flow pump flow ratio but smaller, larger than the centrifugal pump. Concept of mixed-flow pump, the basic structure and working principle of centrifugal force generated by the propeller rotation and thrust the combined effects work, diagonal outflow, also known as mixed flow pump Francis pump, there are worm-type (horizontal) and the guide vane (vertical) two kinds. It combines the advantages of centrifugal and axial 300HW-12 mixed-flow pump, simple structure 350HW-4 mixed-flow pump, efficient wide area, easy to use, suitable for plain polder farmland irrigation and drainage pumping stations. China developed the mixed-flow pump, the volute-type lift 5 ~ 12m, flow 900 ~ 4000m3 / h; vane-type head 3 ~ 25.7m, flow rate 45 ~ 20160m3 / h. Two guide vane pump soap County of Jiangsu Province River pump installation. Impeller diameter 5.7m, flow rate 80 ~ 100m3 / s, lift 6 ~ 12m, speed 75r / min, maximum efficiency 92.1%, and the supporting power 7000kW, is put into operation one of the world's large-scale mixed-flow pump. Francis pump is one of the technical development focus international pump industry. It will partially replace the centrifugal and axial work. In Japan, the Soviet Union, Australia and other countries, the highest efficiency mixed-flow pump has reached or exceeded 90%. 350HW-8 Francis pump _ _ horizontal mixed flow pump Francis pump price (View) provided by the Shijiazhuang-Pump Co., Ltd. faction.
