HMP-4000 Magnetic Leakage Fluorescent Field Particle Detector

HMP-4000 Magnetic Leakage Fluorescent Field Particle Detector

Work principle

Utilizing interaction between magnetic leakage field and magnetic powder at the defect of the workpiece. It takes advantage of the difference between the permeability of surface & near-surface defects of steel products (such as cracks, slag inclusion, hair lines, etc.) and magnetic permeability of steel, the magnetic field at the discontinuity of these materials will be distorted after magnetization, forming part of the magnetic flux leakage and generating a magnetic leakage field, using the characteristics of the magnetic leakage at the defect site to absorb magnetic powder, thereby attracting magnetic powder to form magnetic powder accumulation at the defect - magnetic marks, under appropriate lighting conditions, the defect location and shape are revealed accordingly.

Application

It is designed to detect surface and near-surface micro-defects (e.g., cracks, slag inclusions) of ferromagnetic workpieces (such as bolts, pins, bushings, gears, gear rings, crankshafts, etc.) caused by forging, quenching, grinding, fatigue, and other processes.
