浅谈汽轮机通流部分故障诊断方法研究

Study on Fault Diagnosis Method for Flow Path of Steam Turbine

汽轮机是火电站的重要设备,汽轮机产生故障,会对火电机组运行的经济性、可靠性产生严重的影响,所以汽轮机故障这一问题一直备受关注。通流部分是汽轮机当中最至关重的部分。文章主要结合汽轮机工作原理以及通流部分工作原理,分析汽轮机通流部分故障类型以及问题的形成,提出了一系列诊断方法,以供汽轮机通流部分相关工作人员参考。

Steam turbine is an important equipment in thermal power station, and the failure of steam tur- bine can seriously affect the economy and reliability of thermal power plant operation, so the problem of turbine failure has been paid close attention. The flow path is the most important part of the turbine. Combining with the working principle of the steam turbine and the working principle of the flow part, this paper analyzes the type of the turbine flow path and the formation of the problem, and puts forward a series of diagnostic methods for the reference of the relevant staff of the turbine flow path.
