Microcomputer-Controlled Semi-Automatic Fluorescent MachineMagnetic Particle Inspection MachineIt features a PLC as its core, capable of completing the entire magnetic particle inspection process according to programmed procedures, excluding the observation of loading and unloading. It is a general-purpose AC/DC magnetic particle inspection equipment, allowing for circumferential, longitudinal, and composite magnetization of workpieces, with adjustable current. It includes AC phase control functionality and can be configured for either continuous or residual magnetism inspection methods. Its unique feature is the use of an enclosed spray system for the magnetic suspension liquid during magnetization, with an automatic opening and closing observation door, which solves the issue of splashing during spraying. This machine is suitable for the magnetic particle inspection of ferromagnetic mechanical components such as shafts and disc-shaped parts, and can detect all near-surface defects on the workpiece surface with a single magnetization.
