汽轮机轴向位移和胀差传感器安装探讨

Discussion on Installation of Axial Displacement and Expansion Difference Sensor for Steam Turbine

轴向位移和胀差是直接反映汽轮机动静间隙的两个最重要的技术参数,也是两项重要保护,传感器安装的正确与否直接影响汽轮机能否正常可靠运行。探讨汽轮机轴向位移、胀差传感器的安装、调试过程以及机组运行中存在的一些问题,分析提出解决对策,保证机组安全稳定运行。

The axial displacement and expansion are the two most important technical parameters which directly reflect thestatic clearance of the turbine.They are also the two relevant and important protections.The correct installation of the sensordirectly affects the normal and reliable operation of the steam turbine.The installation and debugging process of the axialdisplacement and expansion sensor of steam turbine and some problems in the operation of the unit are discussed.Thecountermeasures to the problems found are put forward to ensure the safe and stable operation of the unit.
