三河口泵站的水泵选型分析与选择

摘要

主要结合工程实践，阐述了三河口泵站规模和设计标准，从而进一步针对大流量、宽水头泵站选型方案进行了分析，通过泵型、台数及常规机组和双速机组等方面的比较，综合各特征参数最终选定采用3台卧式双速机组方案，这种方案具有运行、管理、检修方便；适应宽水头变幅，水库高、低水位时水泵对应高、低转速，泵站运行更加灵活；水泵效率高、节能环保等特点，可为类似泵站的机组选型提供参考。%Combined with the engineering practice ,the paper expounds the scale and design standard of Sanhekou pumping sta‐tion ,thus further analyzes the selection scheme for large flow rate ,wide head pumping station and finally through the compari‐sons of pump types ,numbers ,conventional unit and double‐speed unit ,the reasonable design scheme according to comprehen‐sive characteristic parameters is adopted ,this scheme is easy to operate ,manage and maintain for pumping station ,which can give reference for the unit selection of similar pumping station .
