ACFM Technique and its Application in Non-destructive Testing of Drilling and Repairing Rig Platform
-
摘要: 无损检测技术对于确保钻修机械平台安全生产十分重要，交流电磁场检测技术(ACFM)由于具有非接触测量、无需标定且一次完成缺陷的定性定量检测等诸多优点而取得广泛应用。首先简介了ACFM技术的检测原理、检测系统及检测标准和认证，并与交流电位降方法(ACPD)、涡流检测方法(ET)等无损检测方法进行了比较。分别以钻修机械平台的钻机井架、底座关键部位焊缝检测和平台吊机检测为例，详细阐述了利用ACFM方法进行工程检测的仪器选择、探头扫描及诊断结果，并分析了检测过程中的干扰因素及处理方法。最后，进一步探讨了ACFM方法应用于钻修机械平台结构损伤检测的可能性和解决思路。

Abstract: Non-destructive testing techniques have very important influence on guaranteeing safety production of drilling and repairing rig platforms, and ACFM method is now in widespread use because of its many advantages such as non-contact measurement, qualitative and quantitative measurement once without calibration. The detection principle, testing system, examination standards and certification of ACFM technique are simply introduced and compared with other non-destructive testing methods including ACPD and ET. Taking the critical welded seams of drilling derrick and substructure and the platform crane for examples based on the drilling and repairing rig platforms, the instrument selection, probe scanning and result diagnosis of the ACFM method applied to engineering practice are illustrated in detail, and interference factors and corresponding processing methods during testing are analyzed. At last, potential fields and solving ideas of the ACFM method applied to detect drilling and repairing rig platforms are discussed. -
