火电厂汽轮机轴瓦的无损检测

Nondestructive Testing of the Thermal Power Plants Turbine Bearing Bush

摘要: 通过分析某台超超临界1000 MW机组汽轮机轴瓦安装前的无损检测结果，给出了采用渗透和超声波技术检验轴瓦基体和乌金的粘合质量的综合检验方法。两种无损检测方法互相印证检测结果，提高了检测灵敏度，解决了单一的检测方法对缺陷检出率与检测灵敏度不高的问题。

Abstract: The nondestructive testing results of turbine bearing bush before installation for 1000MW ultra-supercritical unit are analyzed. The comprehensive testing methods of penetrant and ultrasonic testing for the adhesive quality of the bearing bush are introduced to ensure that the unit can operate safely and stably.
