核电常规岛汽轮机基础结构综述

A summary of the basic structure of the conventional island turbine

介绍了汽轮机基础设计的特点,以及目前常见的汽轮机基础形式,分析了三种基础形式各自的特点。针对核电常规岛汽轮机基础,综述了目前国内主要厂家的基础特点,并进行了对比分析。指出弹簧隔振基础已成为当前大型核电汽轮机基础的主流形式,各厂家的汽机均已有业绩,且采用弹簧隔振后有诸多优点,可在工程中采用弹簧隔振基础形式。

The characteristics of the foundation design of the steam turbine are summarized in this paper. And the common basic form of steam turbine at present. The characteristics of the three basic forms are analyzed. For nuclear power conventional island turbine foundation,the basic characteristics of the main domestic manufacturers are reviewed. The comparison and analysis are carried out. It is pointed out that the spring vibration isolation foundation has become the mainstream form of the large-scale nuclear power turbine foundation at present. All the manufacturers have done the performance,and the spring vibration isolation has many advantages,so the spring vibration isolation foundation can be used in the engineering.
