摘　　要：观景口水利枢纽工程是重庆市重点水源工程之一,工程任务以城市供水为主,同时兼顾小城镇及农村人畜饮水、农业灌溉。泵站从水库通过压力输水隧洞总管引水,在泵站前叉成支管进入泵组,经水泵加压后,汇成一根出水总管至出水池。水泵扬程范围为18.83 m～48.46 m,运行初期设计流量为0.5 m^3/s,设计水平年设计流量为4.76m^3/s,比较选定4台套大泵、2台套小泵匹配变频运行。Guanjingkou Water Control Project is one of the key water source projects in Chongqing. The main task of the project is to supply water in the city, while giving consideration to drinking water for people and livestock and agricultural irrigation in small towns and rural areas. The pumping station diverts water from the reservoir through the main pipe of pressure water conveyance tunnel, forks a branch pipe into the pump group at the front of the pumping station, and assembles an outlet main pipe to the outlet pool after pressurization by the pump. The lift head range of pump is 18.83-48.46 m, the initial design flow is 0.5 m3/s, and the design flow of design level year is 4.76 m3/s. Four sets of large pumps and two sets of small pumps are selected for matching variable frequency operation.
