摘要
介绍氦质谱检漏技术原理,结合大唐保定热电厂11号机组泄漏情况,提出采用氦质谱检漏技术对汽轮机高压缸漏汽情况进行诊断的方案,分析诊断过程及诊断结果,认为氦质谱检漏技术可以快速、准确诊断出高压缸泄漏部位,避免汽轮机振动现象的发生,保障机组的安全运行,并提出提高氦质普检漏技术检测高压缸泄漏部位准确性的建议。
This paper introduces the principle of helium mass spectrometer leak detection technology, combined with leak- age Datang Baoding Thermal Power Plant Unit No. 11, puts forward diagnosis scheme of turbine HP cylinder steam leak with the helium mass spectrometer leak detection technolo- gy,analyzes the diagnosis process and diagnosis results,con- siders that the helium mass spectrometer leak detection tech- nology can diagnosis high pressure cylinder leakage rapidly and accurately, to avoid the phenomenon of turbine vibra- tion,and to ensure the safe operation of the unit,at last,puts forward advices on leakage detection accuracy for high pres- sure cylinder parts.
