| 摘 要： | 远距离输水中的串联加压梯级泵站水锤特性与传统的单级泵站相比有所不同,为此分析了串联加压梯级泵站水锤的各种成因及其过程,提出采取设置带止回装置的旁通管的方式消除因泵站事故引起的高压水锤,采取在管线上间隔0.8 km左右设置一个排气阀的方式消除因事故引起的低压水锤.

| Abstract: | The characteristics of water hammer in cascade pumping station for long distance pressure delivery are different from that in single-stage pumping station.By analyzing the causes and the processes of the water hammer in cascade pumping station,the protective measures are put forward,i.e.using a by-pass pipe with check valve to eliminate high-pressure water hammer caused by pumping station failure,and air vent valves at an interval of 0.8 kilometers along the pipeline to eliminate vacuum cavities generated d... |
