Research on the type selection design and operating project of the large-scale pump unit with high head for HuiNanZhuang Pump Station

HuiNanZhuang Pump Station is the only large-scale pressurized pump station along the main branch of the middle line project of South-to-North Water Diversion and the key control project for water- transfer by pressurized pipe culvert of Beijing section,and it is also the typical building of the middle line project.The pump station is the 1st class project of big(Ⅰ)type,which is with big unit capacity and wide range of various characteristic parameters,the frequency converter and speed regulation with broad range applied,complicated operating conditions,high difficulty of technology.Combining the project characteristics, the praper is mainly to study and analyze the key technical issues about the type selection and operating match of the large-scale pump unit with high head.
