摘要
介绍了某电厂 3# 燃机的压气机因进气滤后不锈钢丝隔网散落造成压气机叶片损伤的情况和检修对策。通过对断裂钢丝进行宏观、显微及腐蚀产物的分析,确定钢丝断裂的主要原因为应力腐蚀开裂。
The main resons of air inlet protection grid collapse which caused damage of the compressor blade and the prevention maintenance taken in siteu are introduced. The results of visual inspection, microscopic inspection and corrosion product analysis revealed that stress corrosion was the main cause of the grid collapse.
