Overview
The MMT-2000 combined portable Magnetic Particle Testing Equipment is a special demonstration equipment designed by MITECH for teaching and training institutions. It adopts an innovative combined Modular structure, integrates the functions of each part, and has the characteristics of small size, light weight and easy installation. It is suitable for teaching demonstrations of magnetic particle flaw detection in classrooms and laboratories, and solves the drawbacks of inconvenient movement of traditional large-scale equipment. The instrument is compatible with 220V conventional and 380V industrial voltages, supports circumferential, longitudinal magnetization and contact method flaw detection, and is widely used in the detection of surface and near-surface fine defects of small ferromagnetic workpieces such as bolts, pins, and gears.
Features
1. Modular design, small size, light weight, easy to carry and install, suitable for teaching demonstration and temporary training places.
2. Compatible with 220V and 380V power supplies to meet different on-site power supply requirements.
3. Supports circumferential, longitudinal, and composite magnetization (at 380V), and the magnetization current is continuously adjustable and displayed at true RMS.
4. The yoke spacing is adjustable (0-270mm) to accommodate workpieces of different sizes and shapes.
5. Can be equipped with strut Probe for contact method flaw detection, suitable for irregular parts.
6. Portable UV lamps can be equipped for fluorescence observation to clearly display the flaw detection results.
7. Can be equipped with aluminum alloy profile shading darkroom for easy observation.
8. Can be equipped with flexible coils to achieve local longitudinal magnetization of complex workpieces.
9. Easy to maintain, Sensitivity is high, A1 type test piece (15/50) shows clearly.
Principle
The instrument works based on the principle of magnetic particle flaw detection. The ferromagnetic workpiece is magnetized by the circumferential or longitudinal magnetic field generated by the device. If there are defects such as crazing and slag inclusion on the surface or near the surface of the workpiece, a magnetic leakage field will be formed at the defect, thereby adsorbing the applied magnetic particles (using fluorescent magnetic particles under fluorescence observation), forming a visible magnetic trace display, which in turn indicates the location and shape of the defect.
Applications
Education and teaching, teaching demonstrations of training institutions, detection of surface and near-surface defects of small ferromagnetic workpieces such as bolts, pins, bushings, gears, and ring gears
