Axial flow pump for power transformers are high specific speed pumps, generally between 500 and 1000 specific speeds. The faster the speed, the lower the head and the greater the flow.
The advantages of axial flow pump for power transformers are large flow, simple structure, light weight, small size, and small footprint. For the adjustable axial flow pump, when the working conditions change, if the blade angle changes, it can still work efficiently, but because the lift is too low, its application range is limited. In order to improve Yang Cheng, the axial flow pump can also be made into multi-stage.
The cavitation performance of axial flow pump for power transformers is poor, and the general allowable vacuum height is only 4~5mH2O (40~50kPa). Due to the characteristics of the axial flow pump itself, large flow is one of the development directions of the axial flow pump for power transformers. At present, our country has become a series of large-diameter super-large axial flow pumps, and the structure tends to choose the direction of regulating vane pumps.
