The impeller, guiding vane, main body, front and back shells, bearings, motor, and main body make up the majority of an axial flow pump. Pressure is produced by the impeller, which rotates and is positioned immediately at the shaft’s end. The guide vane directs the transformer oil to the main flow channel while also converting the impeller’s kinetic energy into pressure to force oil circulation. Due to the pump’s intake and exit being on the same axis, it might be considered a part of the pipeline. As a result, the transformer oil flows directly through the outside of the motor, quickly dissipating the heat.
