Product Description

CDW-4000 fluorescent magnetic particle inspection machine is an electromechanical combined semi-automatic magnetic particle inspection equipment. It consists of a power supply control system, a clamping magnetization device, a magnetic suspension system, and other parts. It is suitable for wet magnetic particle detection of ferromagnetic materials. Cracks and various minor defects on the surfaces and near surfaces of shafts, tubes, and rods due to various reasons such as casting, forging, processing, and fatigue.


    This equipment adopts manual and automatic operation modes, and is controlled by the programmable controller (OMRON 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. After the workpiece is loaded and clamped in place, press the start button to realize the rotation of the workpiece-spraying-magnetization- A series of actions such as double rotation observation. Release the workpiece after manual demagnetization. Circumferential magnetization uses direct current, and longitudinal magnetization uses two sets of special-shaped coils, which have good magnetization effect. The AC magnetization has power-off phase control, and has good remanence stability. It is suitable for both continuous and flaw detection. The composite magnetization forms a rotating magnetic field on the workpiece and displays the magnetic track in all directions at once, which has a high working efficiency.
