| Abstract: | The working mode and characteristics of the pump turbine are introduced. The hydro characteristics of the draft tube at pump mode and turbine mode are described. The theory of draft tube structure design based on stress analysis, the calculation of effective reinforced area for all holes on the draft tube, according to ASME ‘boiler and pressure container specification’, are confirmed. |
