摘要
为研究阻抗式调压塔在长距离有压输水箱涵中水锤防护的作用,文章以某一新建低扬程泵站长距离有压输水箱涵工程为例,进行过渡过程计算,提出了相应的水锤防护方案,并进一步探究了阻抗式调压塔的关键参数对输水箱涵及机组的影响.结果表明,通过合理的闸门关闭规律和空气阀、阻抗式调压塔的组合方案,可以有效地控制输水箱涵内的水锤压力和机组反转转速等关键参数,确保工程安全运行.
Abstract
In order to study the effect of impedance surge tower on water hammer protection in long distance pressure transfer tank culvert,this paper takes a new low head pump station for example,calculates the transi-tion process,puts forward the corresponding water hammer protection scheme,and further studies the influ-ence of different parameters impedance surge tower on water transfer tank culvert and unit.The results show that the key parameters such as water hammer pressure and unit reversal speed can be effectively controlled by the combination of reasonable gate closing rule,air valve and impedance regulator,and the safe operation of the project can be ensured.
