| 摘 要： | 运用水轮机运转特性曲线，求取水轮机工作点的效率和计算水轮机的过流量，以近似率定蜗壳流量系数，并与现场效率试验的实测资料进行了分析比较。结果表明，这种方法具有较高的精度，计算流量与实测流量的最大偏差可控制在４％以下，可广泛应用于蜗壳流量系数的近似率定。

| Abstract: | The hydraulic turbine's performance curve is used for calculating thefurbine's efficiency and flow,in order to compare the flow coefficient of spiral-casing ap-proximately calibrated with the prototype turbine's efficioncy and the test data.The re-sult shows that this method has higher accuracy,with the maximum error of the calcula-tion flow to the measurement flow being less than 4 percent.It can be used widely in theapproximate calibration of the spiral-casing flow coefficient. |

| Keywords: | differential presure method flow coefficient of spiral-casing turbine's flow |
