电厂汽轮机组振动问题分析与解决对策

Analysis on Power Plant Turbine Vibration and Solutions

电厂中的汽轮发电机组在其中所占据的地位极为关键重要。在日常运行中,汽轮机组系统或多或少的存在一定程度的振动问题,此振动问题在一定参数值范围内也是能够允许的。但如果振动问题一旦超过其所允许的范围,则会对整个汽轮机组的工作及电厂的顺利运行带来极为不利的影响。文章首先对电厂汽轮机组振动问题的特点进行了阐述说明,之后结合实例着重对其发生原因及相关的解决对策进行了全面化的分析研究。

Power plant turbine generators play important role in power plant. In daily operation, there exist vibration problems more or less in the steam turbine systems, and the vibration within a certain parameter values is also allowed. However, once the vibration exceeds the allowed range, it will bring enormous negative impact on the steam turbine and the smooth operation of the power plant. Firstly, this paper illustrates the characteristics of the power plant steam turbine vibration problems, and then conducts a comprehensive analysis study of the causes and related countermeasures based on real examples.
