Common Defects of Steam Turbine Low-pressure Rotor Blade in Nuclear Power Plant and Their Inspection Techniques
摘 要
高速旋转的汽轮机低压转子叶片是核电汽轮机组的重要部件之一,除了设计与制造缺陷外,运行期间还可能出现水蚀、共振、疲劳断裂等缺陷.深入分析了叶片常见缺陷及其产生原因,重点讨论了包括超声相控阵、荧光磁粉等在内的无损检验技术,可有效避免因叶片断裂导致的停机事件,为营运单位加强汽轮机叶片质量监督提供了重要参考.
Abstract
Water erosion damage,resonance vibration,fatigue fracture and other design or manufacture defects may occur on the steam turbine low-pressure rotor blade,which is one of the most important rotational equipments used in the nuclear power plants.This article analyzes the common defects of the blades and their causes,introduces ultrasonic phased array,fluorescent magnetic particle inspection and other non-destructive tests,which provides good references for the plants owners to improve the quality monitors of the steam turbine blade.
