航空导管连接卡箍在飞机上被广泛应用,其质量直接影响飞机的飞行安全。在飞机定期大修期间,对航空导管连接卡箍进行相关的无损检测是十分必要的。对拆解下的卡箍进行超声波表面清洗后,采用荧光渗透检测方法对其进行表面质量检测。结果表明,经过对真伪缺陷的识别,能有效发现表面开口裂纹等缺陷,保证了航空导管连接卡箍的安全。

Coupling clamps for aviation pipes are widely used in aircraft and their quality would even directly influence flight safety. It is very necessary to enable the clamps to be nondestructive tested during the aircraft overhaul on a regular basis. The fluorescent penetrant testing method is adopted to test the surface quality of the clamps,which are disassembled and cleaned by ultrasonic surface cleaning. The practice results show that surface cracks can be found effectively through the recognition of authenticity defects,which ensure the quality and safety of coupling clamps for aviation during aircraft overhaul.laiding a solid foundation for the safety of the aircraft flight.
