Research and application of water hammer protection in long distance pressurized delivery tank culvert with impedance regulator
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.
