核电汽轮机低压缸揭缸技术研究与工程应用

Research and Engineering Application of Low Pressure Cylinder Uncovering Technology for Nuclear Power Steam Turbine

某核电机组汽轮机安装现场揭缸作业期间,进行了低低轴系中心与基础弹簧测量试验、通流间隙与碰缸实验、汽缸下挠量校正试验、末级页片径向找中试验,并对试验过程数据进行分析,试验结论为后续同类型汽轮机揭缸和设备安装工作提供参考。

In view of the field uncovering operation of steam turbine of a nuclear power unit,the center of low and low pair wheels and the clearance of flow through half cylinder are measured,and the data of the test process are analyzed,the test results provide reference for the following work of uncovering cylinder and equipment installation of the same type of steam turbine.
