Overview
MITECH CDX-A Magnetic Particle Testing Equipment can accurately and intuitively display the shape, location, size and severity of defects based on the principle of magnetic interaction between leakage magnetic field and magnetic particles. The instrument can be equipped with A, D, O three Probe, to achieve magnetic clamp type, electromagnetic yoke, cross yoke, ring type four flaw detection functions, using a variety of magnetization methods, can detect various parts of the workpiece, is widely used in petroleum, chemical, metallurgy, shipbuilding, aviation, railway and other fields of defect detection.
Features
1. The application of new power mode improves the defect detection depth and surface detection sensitivity.
2. Adjustable yoke spacing to enhance the practicality of the instrument.
3. With power-on lighting function, it is convenient to use in conditions where the rays of light are insufficient.
4. Equipped with three different optional magnetic Probe devices, it enhances the adaptability and Precision of different shape workpiece measurement.
5. Using a variety of magnetization methods, it is almost unrestricted by part size and geometry, and can detect various parts of the workpiece.
6. Adopting ergonomic design and using thyristor as the magnetizing switch, it is convenient for the tester to control the magnetizing switch at any time when holding the Probe.
7. Inspection and flaw detection speed is fast, the process is simple, and the cost is low.
8. It can detect defects under the surface of the workpiece of 0.5-3 mm, and for larger pores, the detection depth can reach 5 mm when DC magnetization.
9. With extremely high detection sensitivity, the magnetic marks formed by the accumulation of magnetic particles on the defect have amplification effect, and the minimum width that can be detected can reach 0.1 micron.
Principle
The object of the ferromagnetic material to be tested is placed in a strong magnetic field or magnetized by a strong current. If there are defects (crazing, folding, inclusions, etc.) on or near the surface of the object, the magnetic field lines will produce magnetic leakage near these defects. When magnetic particles (usually magnetic oxidation iron powder) with good magnetic conductivity are applied to the object, the leakage magnetic field near the defect will attract the magnetic particles, pile up to form visible traces of magnetic particles, and form visible magnetic marks under suitable lighting, thereby showing the location, size, shape and severity of the defect.
Applications
Electric power, oil field, coal mine, chemical industry, railway, automobile, steel structure equipment and other industry products; specific workpiece types include chain rods, crankshafts, bearings, high-strength bolts, springs, forgings, petrochemical pipe fittings, valves, blades, gears, anchor chains and welds and other geometrically complex workpieces.
