It is reported that some foreign submersible pump manufacturers, has successfully solved the problem, and got very good application in practical engineering, the south-north water diversion project can draw lessons from.
Exhibition model submersible pump device test pump station of high and low operation efficiency, and depends on the submersible pump assembly efficiency not only about the efficiency of the pump segment itself. The merits of the guide vane pump, in and out of the water design is also the main factors influencing the efficiency of pumping devices, such as, therefore, should attach great importance to the guide vane pump structure design and the design of the inlet and outlet conduit and other hydraulic structures, and study its overall Angle from the device that combined with the optimization of the pump wheel problem. Domestic existing pump station of the direct drive submersible pump is usually used in indirect transmission and gear coupling two ways, direct drive has the characteristics of high efficiency, safe and reliable, gear transmission has the advantages of reducing motor size and weight.
Weihu submersible sewage pump Suggestions to carry out a variety of different types of model pump test and research, such as vertical shaft according to pump station head, flow characteristics, reasonable choose blade adjustment way in order to adapt to the change of the water diversion in the process of pump station head, flow, make the submersible pump run efficiently, most of the pump station adopts the submersible pump is suitable for adjustment. Submersible pump blade adjustment way is mainly mechanical adjustment and hydraulic pressure to adjust two. Because of the large pumping station blade when adjusting torque is bigger, generally adopts the hydraulic adjustment way is better. Domestic commonly used hydraulic adjustment problems such as the seal oil leakage, water pollution, is not conducive to ensure water quality requirements.
