Special fluorescent magnetic particle flaw detector for crankshaft is magnetic particle flaw detection equipment. It consists of a power supply control system, a bracket lifting device, a composite magnetization device, a clamping device, a displacement observation system, a demagnetization system, a magnetic suspension spray recovery system, a fluorescence observation system and the like, and is specially used for checking various cracks and slight defects on the surface and near the surface of parts by a wet magnetic particle method.

采用可控硅变流技术，将高电压小电流转换成低电压大电流，周、纵向电流均分别连续可调，交流磁化具有断电相位功能，既可用于剩磁法探伤，也可用于连续法探伤。周向磁化检测方式采用传统的直接通电的磁化方法，纵向磁化采用线圈感应的磁化方法，设备一次性全方位磁化检查工件表面和近表面的各种裂纹和细微缺陷。

Silicon controlled converter technology is adopted to convert high voltage and small current into low voltage and large current, and the circumferential and longitudinal currents are continuously adjustable respectively. AC magnetization has the function of power-off phase, which can be used for residual magnetic flaw detection and continuous flaw detection. The circumferential magnetization detection method adopts the traditional direct current magnetization method, the longitudinal magnetization adopts the coil induction magnetization method, and the equipment performs one-time omnidirectional magnetization to check various cracks and fine defects on the surface and near surface of the workpiece.
