无触点分段磁化和退磁装置设计

Design of Non-contact Segmented Magnetization and Demagnetization Device

为解决钢管漏磁探伤中存在的管端检测盲区以及常规调压整流设备的笨重、维护更换困难等问题,设计制作基于可控硅控制的无触点式分段磁化、退磁一体化装置。介绍了一体化装置的具体内容、装置构成和原理,并对使用方法进行了描述,装置使用后实现了磁化、退磁的分段控制,产生了较高的经济效益。

In order to solve the blind zone problem of the tube end detection existing in the magnetic flux leakage inspection of steel pipes, difilculties in maintenance and replacement of conventional voltage regulating rectifier equipment and interference problems when there are conventional contacts, a non-contact segmented magnetization and demagnetization integrated device was designed and manufactured based on thyristor control. This paper mainly introduces the specific content, device structure, principle and description of the integrated device. The application of the segmentation control of magnetization and demagnetization has creased the high economic benefits.
