Water hammer protection system and method for long-distance water delivery pump station and design method
The invention relates to a water hammer protection system and method for a long-distance water delivery pump station and a design method. The water hammer protection system comprises a water inlet pool located at a low position, and the water inlet pool is connected with a pipeline front section provided with a water pump, a low-position control valve and an ascending pipeline; the water outlet pool is connected with the pipeline rear section of the horizontal or descending pipeline, an overflow type water pool is arranged between the pipeline front section and the pipeline rear section, and a high-position control valve is arranged at the position, close to the water outlet pool, between the overflow type water pool and the water outlet pool. The water delivery system is divided into a front-section pump station water delivery subsystem and a rear-section gravity self-flowing water delivery subsystem which are weakly associated by utilizing an overflow type water pool. Only limited water on the front side of the overflow pool and in the pipeline can flow back into the water pump, the problem of reverse rotation and overspeed of the water pump is avoided, and the difficulty of water hammer protection is reduced. And for the gravity self-flowing pipeline on the rear side, the pipeline is controlled not to generate negative pressure or smaller negative pressure. The system is low in construction cost and reliable in operation, and is an excellent solution for preventing the water hammer of the inclined pipeline.
本发明涉及长距离输水泵站水锤防护系统和方法及设计方法，包括：位于低位的进水池，进水池与带有水泵、低位控制阀及上升管道的管道前段连接；位于高位的出水池，出水池与水平或下降管道的管道后段连接，管道前段和管道后段之间设置溢流式水池，溢流式水池与出水池之间接近出水池的位置设置高位控制阀。本发明利用溢流式水池将输水系统分成两个弱关联的前段泵站输水子系统和后段重力自流输水子系统。只有溢流池前侧和管道内有限的水体，才能倒流进入水泵，不会造成水泵反转超速问题，降低了水锤防护的难度。对于后侧重力自流管道，控制管道不产生负压或较小负压。所述的系统工程造价低，运行可靠，是倾斜性管道防水锤的优良解决方案。
