【摘要】 对大同二电厂 2号机和太原二电厂 8号机两台大型空冷机组振动原因进行了初步探讨。排汽缸温度对轴承支承标高变化的影响是引起空冷机组不稳定振动的重要原因。合理的空冷汽轮机结构设计和严格的安装检修质量 ,是提高空冷机组运行稳定性的有效途径更多还原

【Abstract】 primary discussion on vibrating cause of large scale air cooling generating unit was proceeded the influence of exhaust hood temperature on change of bearing supporting height scale is the important cause of unstalbe vibrating of the unit,the valid way to improve operating stability of the unit is the rasonable stucture design and strict installating overhand quality.更多还原
