Special fluorescent magnetic particle flaw detector for crankshaft
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.
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.
