Magnetic Particle Flaw Detector

1. Product Introduction

The CYD-15000A multi-purpose magnetic powder flaw detector is manufactured in accordance with the JB8290-1998 standard and the agreement between the two parties. This instrument is a portable multi-purpose magnetic powder flaw detection instrument, which can AC magnetize and AC demagnetize the workpiece to be detected automatically ; it can be used as continuous and residual magnetic method magnetic powder flaw detection; it can be fixed in workshop or laboratory, and can also be carried to the flaw detection site for use. With accessories, the special-shaped parts of various parts can be  magnetized properly and can magnetize large-sized parts in segments.

The phase control function of the instrument AC magnetization tape is powered off, and the residual magnetism is stable to ensure the quality of the flaw detection; the automatic demagnetization can  attenuate from the used magnetization current value to zero automatically, causing the residual magnetism to disappear. Easy to operate and good effect. The instrument uses thyristor to adjust its conduction angle to adjust the magnetization and demagnetization currents to achieve contactless adjustment of large currents and extend the service life of the instrument.

The Magnetic Particle Testing (MPT) Machine is a non-destructive testing (NDT) device designed to detect surface and near-surface defects such as cracks, seams, inclusions, and laps in ferromagnetic materials. By magnetizing the test object and applying magnetic particles (dry or wet), the system reveals flaws through particle accumulation at discontinuities.

Widely used in automotive, aerospace, railway, machinery, and manufacturing industries, this machine offers high sensitivity, fast testing, and intuitive operation. It is ideal for inspecting components like shafts, gears, welds, axles, and castings. Available in bench-type, portable, and automatic conveyor systems, it suits various testing environments from production lines to field inspections.

FAQ

Q1: What materials can be tested with this machine?

A: Only ferromagnetic materials such as carbon steel, alloy steel, cast iron, and nickel-based alloys.

Q2: Can it detect internal defects?

A: MPT is most effective for surface and near-surface flaws, not deep internal defects.

Q3: Is demagnetization required after testing?

A: Yes, demagnetization is recommended to remove residual magnetism from parts.

Q4: What types of magnetic particles are used?

A: Both dry powders and wet fluorescent suspensions can be used, depending on visibility and lighting.

Q5: Is training required to operate the machine?

A: Basic NDT training is recommended for accurate and standards-compliant testing.
