摘要
涡流探头是抽油杆涡流检测的关键器件,能够快速准确地检测抽油杆表面存在的裂纹源。介绍了抽油杆专用探头的设计原理、探头的制作要求及其检测频率的确定。实验表明该探头满足现场使用的要求。
Current probe is the pivotal part of the current testing apparatus for sucker rod. It can inspect micro cracks on the sucker rod surface quickly and exactly. The design theory of the special probe for sucker rods testing, applied frequency and its development are described in this paper. Test result showed that the probe could meet the needs of sucker rods testing.
