XWD-D Rotating Magnetic Field Magnetic Particle Flaw Detector for Bogie Frame

Applicable scope

The inspection machine is suitable for wet fluorescent magnetic particle inspection of bogie frame of railway vehicle and emus

Features and Technical parameters

1.  Non-contact magnetization technology of rotating magnetic field is adopted to magnetize the bogie frame as a whole, the magnetization device does not need to contact with the workpiece, and there is no heating or ignition in the process of flaw detection, which avoids the maladies of burning the workpiece by electric ignition, and the magnetization current is stable and reliable, improving the reliability and safety of the equipment.

2.  The bogie frame is placed horizontally on the supporting slewing driving mechanism. During flaw detection, the frame automatically rotates and magnetizes. The whole inspection can be completed by turning the frame horizontally for one circle

3.  The magnetization device and the truss support and rotation device adopt the inclined structure form, so that the truss under test tilts at a certain Angle during the inspection process, which can effectively eliminate the accumulation of magnetic suspensions formed on the upper surface of the truss and facilitate the retention and observation of magnetic marks

4.  Frequency conversion device is used to control the rotation of the tested frame, which makes the observation and operation more convenient.
