高扬程长距离引黄灌溉泵站输水管道充水方式研究

Study on Water Filling Mode of Water Pipeline in High-lift and Long-distance Irrigation Pumping Station

高扬程长距离引黄灌溉泵站在首次启动时需要对输水管道进行空管充水,输水管道充水系统使用概率低且充水的水量大。针对该特点,宁夏盐环定扬黄共用工程采用水泵变速调节充水方式,充水操作简单、自动化程度高,保证了水泵充水的安全稳定运行,且不增加额外的工程投资,为今后类似工程提供了经验与参考。

When the pumping station of high-lift and long-distance Yellow River diversion is first started, it needs to fill the empty pipe of the water conveyance pipeline. The probability of using the water conveyance pipeline filling system is low and the water quantity is large. In view of this characteristic, Ningxia Salt Ring Ding Yanghuang Common Project adopted pump variable speed regulation water filling mode. The water filling operation was simple and highly automated, which ensured the safe and stable operation of pump water filling without additional project investment. It provides experience and reference for similar projects in the future.
