摘　　要：外高桥三期汽动给水泵是国内首台1 000MW机组全容量汽动给水泵,同时,小汽机自带凝汽器,前置泵与主给水泵布置在同一个基础台板上。通过严格而完整的系统设计,包括弹簧隔振器选型、布置、动力分析与静力分析,泵组在投运后,运行效果良好,基础振动小。The feed pump in Waigaoqiao Phase III Project is the first full capacity turbine-driven feed pump for I 000 MW units in the nation. It also equipped with condenser, and the pre-pump and main pump are located on same base plate. Through rigorous and complete system design, including spring isolator selection, arrangement, dynamic analysis, and static analysis, pump set operate well after being put into operation, with low base vibration.
