Product Description

CDG-2000 nut-specific fluorescent magnetic particle inspection is an electromechanical discrete semi-automatic fluorescent magnetic particle inspection equipment. It consists of a power supply control system, a magnetization system, a magnetic suspension spray system, a fluorescence system, and a demagnetization system. It is suitable for testing the surface and near surface of various bushings made of ferromagnetic materials by wet magnetic powder method due to forging, processing, fatigue and other causes of cracks and various minor defects.

    This equipment adopts manual and automatic operation modes, and is controlled centrally by a programmable controller (PLC). When it is manual, it can perform single-step independent operation of each function; when it is automatic, the device automatically executes the PLC internal program. In the initial state, the workpiece is manually threaded, the material is placed in place, and the "Start" button is pressed to automatically perform the transfer. -Shower-magnetization-transmission-and a series of actions. The direct magnetization method is adopted for the circumferential magnetization, and the coil induction method is used for the longitudinal magnetization, which has a good magnetization effect. The composite magnetization forms a rotating magnetic field on the workpiece, and displays magnetic marks in all directions at once, which has a high working efficiency.
