摘要
探讨了简单式尾水调压室位置对尾水管最小压力值的影响。通过数值计算和工程实例,证明简单式尾水调压室越过某一临界位置向厂房方向移动,对尾水管最小压力值不利;增大调压室面积会明显改变尾水管最小压力值。
This article discusses the influence of simple taitrace surge tank location on draft tube minimum pressure. By mumerical simulation,this article certificates a fact,it is unfavorable to the minimum pressure of draft tube by moving simple tailrace surge tank towards the plant while the distance between them exceeds a critical value. Enlarging the sectional area of surge tank obviously changes minimum pressure in draft tube.
