摘　　要：根据《滇中引水工程丽江市水资源综合利用配套工程古城区金安桥库区提水工程初步设计报告(报批稿)》(2020年10月),初设阶段应对泵站水力机械设备进行复核计算,本次主要进行水泵运行工况分析(以一级泵站为例),即水泵工作点计算,电机功率复核计算,泵站装置效率计算,水泵安装高程计算。通过计算,为初设阶段工程设计提供依据。According to the“Preliminary Design Report of the Jin anqiao Reservoir Area in the Ancient City District of the Lijiang Water Resources Comprehensive Utilization Project(Draft for Approval)”(October 2020).The hydraulic machinery and equipment of the pumping station should be rechecked and calculated at the initial stage.This time,we mainly analyze the operating conditions of the pump(take the first-stage pumping station as an example),that is,the calculation of the pump operating point,the calculation of the motor power,the calculation of the efficiency of the pumping station,and the calculation of the installation elevation of the pump.Through the calculation,it provides the basis for the engineering design in the preliminary design stage.
