灌排结合泵站
pump station for both irrigation and drainage
guanPai jiehe bengzhan灌排结合泵站(pump station for bothirrigation and drainage)既能灌溉又能排水的抽水站。一站两用灌排结合可以提高设备利用率和单位功率效益。 灌排结合泵站建筑物的布局型式很多，它与灌溉、排水的要求及当地地形、水源情况、投资能力和运行方式有密切关系。在规划设计时要尽量考虑既能抽水灌排又能自流灌排。 图示为一自流排水为主的灌排结合泵站的平面布置图。当外河水位低于排水干沟的水位时，打开自流排水闸和节制闸，排水区的积水即可自流排出;当外河水位高于排水干沟水位时，则应关闭自流排水闸，启动水泵机组，通过排水管将积水排至外河。当需引河水进行灌溉时，打开进水闸，关闭节制闸，启动水泵机组，抽水进入出水池，通过灌溉干渠，将水送至灌区。这是一种闸站分建式的灌排结合泵站。此外，还有闸站合建式的灌排结合泵站和正向抽排反向扬水灌溉的灌排结合泵站。 规划设计灌排结合泵站时，要处理好以下几方面的问题:①合理地选定站址和建筑物布局;②根据灌出水池灌溉干染言泄区(水源)┌─┬─┐│ │ │└─┴─┘灌排结合泵站示意图排主次并结合泵型正确地计算水泵安装高程;③灌溉结合泵站的机组数目不宜过多;④灌溉及排水扬程相差较大时，应分别修建高低两个出水池，灌排分开;⑤妥善布置泵房内部的机电设备及管道。 (陈固)
