Experimental research on guide hydro-dynamic torque of a pump turbine in turbine mode
摘要
Abstract
To obtain the hydro-dynamic torque magnitude and its variation law of the pump turbine under the turbine mode,the electromotive stress analysis method and the specially processed shaft of guide vane were applied in a pump turbine model of the domestic pump storage plant.The hydro-dynamic torque of each guide vane was investigated under the situation of synchronous guide vane and misaligned configuration respectively.The main conclusions are as follows:once the synchronized guide vane is employed,with the opening increasing,the hydro-dynamic torque factors magnitude of the guide vane has the consistency among all tested vanes,and the direction of the torque shift gradually from the turn-off direction to the turn-on direction.When the 10# guide vane is set as the misaligned guide vane,and the difference between misaligned guide vane opening and the synchronous one is less than 16.4％,the hydro-dynamic torque factors of the tested guide vanes tend to be distributed regularly.However,when the opening difference is bigger than 16.4％,the hydro-dynamic torque increases sharply with the use of the misaligned guide vane,and the hydro-dynamic torque factors of the different guide vanes change significant.关键词
