Overview
CDX-ⅲ Portable Magnetic Particle Testing Equipment is a multi-purpose magnetic particle flaw detection equipment launched by PORUIKE brand, which is a non-contact ultra-small testing instrument. The instrument uses thyristor as a touchless point switch, which has the characteristics of low noise, long life, simple and convenient operation, strong applicability and stable work. It combines the advantages of Portable and mobile models, expands the use and simplifies the operation. It has a variety of magnetization methods such as AC swirl/spin magnetic field and magnetic yoke. It is a simple, reliable, lightweight, practical and effective multi-functional magnetic particle flaw detection instrument, especially suitable for surface parts that do not allow electrical arcing.
Features
1. According to the magnetic interaction between the leakage magnetic field and the magnetic particles, the shape, location, size and severity of the defect can be intuitively displayed, and the nature of the defect can be determined.
2. The application of a new power mode improves the depth of defect detection and the Sensitivity performance of surface detection.
3. Adjustable yoke spacing expands the practicality of the instrument.
4. With power-on lighting function, it is convenient to use in conditions where the rays of light are insufficient.
5. Equipped with four different optional magnetic Probe devices (A, D, Ec, O types), enhancing the adaptability and Precision of different shape workpiece measurement.
6. Using a variety of magnetization methods, it is almost unrestricted by part size and geometry, and can detect various parts of the workpiece.
7. The thyristor is used as the magnetizing switch, and the ergonomic design is adopted, which is convenient for the tester to control the magnetizing switch at any time when holding the Probe.
8. Inspection and flaw detection speed is fast, the process is simple, and the cost is low.
9. 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.
10. 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 instrument works according to the principle of magnetic interaction between the leakage magnetic field and magnetic particles. When the workpiece is magnetized, if there is a defect on the surface or near the surface, a leakage magnetic field will be formed at the defect. At this time, magnetic particles are applied, and the magnetic particles will be adsorbed by the leakage magnetic field, so that they can gather at the defect to form a magnetic mark visible to the naked eye, intuitively showing the shape, location and size of the defect.
Applications
Various fillet welds, internal and external angles of large workpieces, curved surfaces, flat workpieces, various welds, curved surfaces of various geometric shapes, planes, pipes, boilers, spherical tanks and other Pressure Vessels, workpieces that can be put into coils Circumferential crazing detection, workpiece fatigue trace detection, workpiece demagnetization
Standards
Can clearly display (30/100) A-type standard slot
Steps
1. According to the workpiece shape and inspection requirements, choose the appropriate Probe (A-type horseshoe yoke Probe, D-type electromagnetic yoke Probe, Ec-type swirl/spin magnetic field Probe or O-type magnetic ring coil).
2. Connect the Probe to the host and turn on the power supply (AC 220V +/- 10% 50Hz).
3. Place the Probe on the surface of the workpiece to be inspected and adjust the yoke spacing (if applicable) to ensure good contact.
4. Holding the Probe, the magnetization process is controlled by an ergonomically designed switch.
5. Applying magnetic particles in the magnetized region.
6. Observe the surface of the workpiece, magnetic particles will gather at the defect to form a magnetic mark, so as to identify the defect.
7. After the test is completed, if demagnetization is required, the O-type magnetic ring coil can be used for remote demagnetization.
