摘要
通过引进型国产300MW汽轮机在启动试运中出现的一次窜轴事故,根据计算机追忆打印的有关图表、数据分析了产生事故的原因,并提出了为防止类似事故重演应采取的措施和建议。经采取措施后该机组多次又在相同情况下启机,已安全运行。说明分析正确,措施得当,值得同类型机组借鉴。
An axial-displacement accident happened during commissioning of a tecnic-irttroduced domestic 300MW steam turbine. Based on graphics and data from microcomputers recall printing , analysed the cause of accident and submitted measures and proposals to prevent similar accidents. After implementing of these measures, this turbine set was safe through several starting under the same conditions, It proves that the analysis is correct, the measures are suitable and valuable to same model sets.
