小口径漏磁内检测磁化装置的设计与运动分析

Design and motion analysis of the magnetization device for small diameter magnetic flux leakage internal detection

针对小口径管道对漏磁内检测设备通过性要求较高的情况,设计了一种浮动式磁化装置,在满足漏磁内检测励磁参数的基础上,调整检测器在管道中的运动姿态实现了较高的通过性。通过ADAMS动力学分析软件计算装置在不同工况下的通过性能,初步验证了方案的合理性,为小口径管道寿命预测和科学管理的发展提供了技术支持。

In view of the high passability requirements of small caliber pipelines for magnetic flux leakage internal detection equipment, a floating magnetization device is designed to adjust the movement attitude of the detector in the pipeline on the basis of meeting the excitation parameters of the magnetic flux leakage internal detection, and hence higher pass ability can be achieved. The passing performance of the ADAMS dynamic analysis software calculation device under different working conditions initially verified the rationality of the scheme, and provided technical support for the development of small diameter pipeline life prediction and scientific management.
