摘　　要：随着节能减排技术的发展,给水泵配置方案的重要性日益显现。文章主要介绍了国外给水泵由汽轮机主轴直接驱动的方案,并分析对比该方案与目前国内所普遍采用的电机驱动及小汽机驱动方案的优缺点。探讨给水泵主轴驱动在大功率直接空冷机组中的应用方案,以供同类机组设计参考。With the development of energy saving and emission reduction technology,the configuration scheme of the feed water pump becomes more important.This paper mainly introduces the scheme that the feed water pump is directly driven by the turbine main shaft in abroad,analyzes advantages and disadvantage of the motor driving and small turbine driving schemes which are usually used in China.The scheme of feed water pump main shaft driving which applys to high-power direct air cooling unit is discussed,and provides a reference for similar units design.
