CDG-888 fluorescent magnetic particle testing machine is an electromechanical combined semi-automatic magnetic particle testing equipment, which is composed of power control system, clamping magnetization device, magnetic suspension system, etc. it is suitable for wet magnetic particle testing of the surface and near surface of the semi axle, tube and bar parts made of ferromagnetic materials caused by casting, forging, processing, fatigue and other reasons Micro defects.
The equipment adopts two operation modes, manual and automatic, and is centrally controlled by OMRON PLC. In manual mode, the single step operation of each function can be carried out; in automatic mode, the equipment automatically executes PLC internal program. After the workpiece is loaded and clamped, press the start button to realize a series of actions such as workpiece rotation spray magnetization. Loosen the workpiece after manual demagnetization. Two groups of special-shaped coils are used in the circumferential magnetization and the longitudinal magnetization, which have good magnetization effect. AC magnetization with power-off phase control has good remanence stability, which is suitable for both continuous method and remanence method. The compound magnetization forms a rotating magnetic field on the workpiece, which shows the magnetic trace at one time, and has a high working efficiency.
