国产600MW汽轮发电机组轴承动态标高变化规律试验研究

本文以国产600MW汽轮发电机组为研究对象,采用现场测试的方法获得各轴承座中分面处标高的动态变化规律,找到影响各轴承座标高动态标高变化的因素。研究表明:机组状态参数的变化对各轴承的标高有较大影响。机组冲转、升速过程中,轴承标高变化主要取决于轴承座本身的温度变化。本文的研究结果,对合理分配轴承的动态载荷,确保机组安全运行提供了参考依据。

Research on Changes of Bearing Dynamic Elevation of Domestic 600MW Turbo-generating Unit

This paper researched on domestic 600MW turbine generator.By field testing,the dynamic changes of elevation of each bearing equatorial plane was obtained,and factors that affect each beating dynamic elevation change were found.The research shows that changes of the parameters of the unit have a great impact on each bearing.During unit rotation and acceleration process,bearing elevation changes mainly depend on the change of temperature of the bearing itself.The results provide a reference of rational allocation of dynamic load of bearings and ensure the safe operation of the unit.
