Mixed flow pump is widely used. It is mainly used for farmland irrigation and drainage, power plant water supply, urban water supply, shipbuilding and ship propulsion.
The rural construction of a large number of mixed flow pump irrigation and drainage stations, these stations close to create the conditions for the flood insurance. Since the implementation of the "principle of static walking on two legs, the commune and brigade level established in small irrigation station, some county and commune farm machinery factory can in the production of small and medium-sized mixed flow pump, the general agricultural machinery station can repair mixed flow pump. At the same time, by the national investment to build a series of large-scale water control project. All of these have made great contributions to the development of agriculture.
Range of use :
Single-stage vortex shell mixed flow pump with the use of head generally 5 ~ 10 meters, low head series for 2 ~ 6 meters. Single stage guide vane mixed flow pump, the use of head, vertical for 10 ~ 25 meters, horizontal for 3 ~ 8 meters. Multi stage mixed flow pump head up to more than 150 meters. Mixed flow pump flow according to the diameter of the pump increases or decreases, the flow rate and the centrifugal pump and axial flow pump is basically the same.
Each mixed flow pump has a certain range of use, from the efficiency point of view, in the maximum efficiency point on both sides of the use of a range of 7% or more reasonable to use. Because the water level of pumping station is change. Therefore, the pump is not possible completely at the maximum efficiency point of operation, as long as the main operating points in the vicinity of the design point, the rest cases but also consider it, individual cases could not temporary replacement pump, had to sacrifice some efficiency.
