火力发电厂大型汽轮机振动异常分析及故障判断

Thermal power plant of large steam turbine abnormal vibration analysis and fault diagnosis

汽轮机是火力发电厂中最重要的机组部件之一,它的安全稳定性能是确保其机组运行安全和平稳的前提,而且直接关系到电厂的正常工作状况,因此,对汽轮机的维护也成为了电厂日常管理中的重要项目,加强电厂汽轮机常见故障分析与排除的研究,是要求电建施工人员必须具备的重要技能。因此,对机组工作人员来说,加强对汽轮机常见故障的认识,总结故障排除技巧,是作为机组人员必须具有的素质。本文重点对火力发电厂大型汽轮机异常运行参数分析及故障判断进行了探讨,通过举例子介绍了汽轮机的一些常见的故障现象,并提出了以供参考的相应解决办法。

Steam turbine is one of the most important components of units in thermal power plant,the safe and stable performance of the unit operation is the premise to ensure the safety and smooth,but also directly related to the normal working conditions of power plant,therefore,the maintenance of steam turbine has become the important project of power station of daily management,strengthening research and exclusion common faults of steam turbine analysis,is an important skill requirements of electric power construction personnel must have.Therefore,the unit staff,strengthen the understanding of steam turbine fault,summarize troubleshooting tips,as the crew must have quality.This paper focuses on the thermal power plant of large steam turbine abnormal operation analysis and fault diagnosis parameters are discussed through examples, introduces some common faults of steam turbine,and puts forward some corresponding measures for reference.
