连接管长度对调压井非恒定流现象的影响

The effect of riser length on non-steady water in surge tank

通过理论和解析方法讨论连接管较长时,其内水体惯性对调压井水锤压力和水位波动的影响。实例分析表明:连接管长度增加可使调压井水锤压力升高,水位波动幅值减小。

Based on analytical method,the paper shows that raising the length of a riser can elevate the water-hammer pressure and reduce the fluctuation of water level effectively in surge tank.
