在富春江水电站和湖南镇水电站水轮转轮静平衡试验中,发现用不同的试加重量 P测出转轮下沉值 H,再按公式求出的灵敏度h,调整灵敏度时,改变灵敏度数值国⊿h 与按公式计算出的灵敏度的改变值也不同。本文提出“二次试验法”校正水轮机转轮不平衡方法,以解决这个问题。并且就静平衡试 In the static equilibrium test of the waterwheel runner of Fuchunjiang Hydropower Station and Hunan Hydropower Station, it is found that the sensitivity H is obtained by using different test weight P to determine the rotor sinking value H, and then the formula is used to adjust the sensitivity. When the sensitivity is changed, National ⊿ h and according to the formula to calculate the sensitivity of the change value is also different. This paper proposes a “second test method” to correct the imbalance of turbine runner to solve this problem. And static balance test
