常规磁粉探伤设备在对工件进行周向磁化时,常会因为夹头与工件接触不良而造成工件电灼伤。针对此问题研制了通道式旋转磁场探伤机,该探伤机利用交叉线圈产生旋转磁场,与工件无电接触,可有效避免电灼伤。
Conventional magnetic particle inspection equipment in the circumferential magnetization of the workpiece, often because of poor contact with the chuck and the workpiece caused by electrical burns. Aiming at this problem, a channel rotary magnetic field detector has been developed. The detector uses a cross-coil to generate a rotating magnetic field without electrical contact with the workpiece, which can effectively prevent electrical burns.
