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, two forms of worm-type (horizontal) and the guide vane (vertical) . It combines the advantages of centrifugal and axial flow, simple structure, 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 400HW-7 mixed flow pumps, up 92.1%, while 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%. The distance between the plane and the lower plane rack (6) measuring motor Francis pump, the distance between the plane and the lower plane of the frame on the motor, and make a record. (7) Measure the length of the mean value of the stator core silicon steel, the measurement of the stator core to the top end surface of the stator housing 350HW-8 from the mixed-flow pump, measure the height 400HW-5 mixed-flow pump stator casing, and accordingly do record. (8) measuring the effective length of the rotor core silicon steel, the measurement of the rotor core from the yoke between the rotor surface to the top silicon steel, and measuring the rotor core yoke plane-to-plane distance from the motor coupling and accordingly make a record. Calculated by the measuring data center design elevation and a combination of the impeller, the motor can be determined based on the actual installation elevation. Mixed-flow pump, 400HW-8 mixed flow pumps, mixed flow pump volute (certified merchants) Ltd provided by the Shijiazhuang-send pump. Shijiazhuang-school Pump Co., Ltd.
