摘要
将电涡流传感检测技术与机械传动设计技术相结合，研制了集运动机构、张合机构、随动机构及电涡流传感无损检测为一体的抽油杆电涡流无损检测装置，实现了对抽油杆这种直径16～25mm、长6～8m、杆体细、杆头粗的特殊细长柔性杆的在线自动检测。主要解决了传感探头与检测表面间隙不大于2mm、运动速度保持0．1～0．25m／S等关键问题。现场实际运行表明，该装置达到了设计精度，符合生产要求。
Based on the technology of eddy current and mechanics, developing automatically eddy current nondestructive inspecting device of pump-rod, including moving mechanism, open and close mechanism,following mechanism and eddy current inspecting sensor. It realizes on-line inspection to flexible pump-rod, which is 6 ~ 8 m in lenth, 16 ~ 25mm in diameter, so specially long and thin a rod. It mainly solves essential technical problems such as clearance, moving speed etc. Practice shows that It attains the design accuracy.
