- 摘要:
- 在长距离供水工程中发生的停泵水锤是威胁工程安全的重要因素,对于多泵站供水工程,存在不同泵站停泵问题,给防护措施的设计带来了困难。基于有压瞬变流基本理论,结合实际工程模拟了不同泵站停泵过渡过程,提出在干线上设置调流阀,当泵站掉电时通过阀门联动将管道系统隔离为多个封闭系统进行防护的方法,并验证了该水锤防护方法的效果。结果表明,通过采用合理的中部调流阀关闭策略将供水管道隔离为独立的封闭系统,一方面可以降低水锤防护措施的规模,另一方面也可以降低单个泵站掉电对系统的影响。
- Abstract:
- Water hammer resulting from pump shutdown in long-distance water supply projects poses a significant threat to project safety. In multi-pumping station systems, the occurrence of pump stoppages across different stations introduces additional complexity in the design and implementation of effective protective measures. Based on the fundamental principles of pressurized transient flow and in conjunction with practical engineering applications, the transition processes of various pumping stations during pump shutdown were simulated. A method involving the installation of a flow regulating valve along the main pipeline was proposed. In the event of a power failure at the pumping station, the pipeline system could be divided into multiple isolated closed systems through coordinated valve operations, thereby providing effective protection. The efficacy of this water hammer mitigation approach was subsequently validated. Isolating the water supply pipeline into an independent closed system through a properly designed closure strategy for the middle regulating valve reduced the scale of water hammer protection measures. Furthermore, the impact of power failure at a single pumping station on the overall system could also be effectively minimized.
