1000MW二次再热机组汽轮发电机弹簧隔振基础应用分析
|
摘要
比较框架式基础和弹簧隔振基础两种基座型式,论证了弹簧隔振基础在西门子5缸长轴系汽轮发电机组中应用的合理性。通过一系列测振试验表明,弹簧隔振基础保障整个结构安全稳定,为机组提供了稳定运行环境。
The rationality of the application of spring vibration isolation foundation in siemens 5 cylinders and long shafting turbine-generator set is demonstrated in this paper by comparing the two base types of frame foundation and spring isolation foundation.The application of spring vibration isolation foundation in the second phase project of guodian taizhou power plant is also introduced in this paper.A series of vibration measurement tests indicates that the spring vibration isolation foundation can bring more stable security guarantee for the whole structure and provide a better stable operating environment for the unit.
