Various use methods of magnetic particle flaw detector

Multi-useMagnetic Powder Flaw Detectorsis a mobile magnetic flaw detection machine, can be inspected the workpiece for AC magnetization and automatic demagnetization, it can be used for magnetic flaw detection and magnetic field testing, can be fixed in the workshop or laboratory, can also be carried to the site of the flaw detection, can make the opposite parts of each part to obtain the appropriate magnetization, can make large size parts partial magnetization. The instrument uses logic circuit, with power off phase controller, the stability of residual magnetism, to ensure the quality of detection, automatic demagnetization from the magnetic current used to gradually decay to zero, so the residual magnetism disappear, easy to operate, good.

1. Magnetic particle flaw detection principle ferromagnetic material parts magnetization, because the defect leads to the magnetic field lines of continuous caused by the local distortion of the magnetic field lines, when discontinuity is located or near the surface of goods, its magnetic lines of local distortion will cause some of the magnetic flux leakage of the surface of the workpiece to form leakage magnetic farmyard The magnetic flux on the surface of the workpiece is absorbed by the leakage magnetic field to form a visible magnetic mark under suitable illumination, showing the discontinuity of position, shape and size.

2. The detector is designed and manufactured in accordance with the basic j13/t8290-1998 "magnetic particle flaw detector" magnetic particle flaw detection standards and design principles, continuous detection methods, can detect the workpiece surface and near-surface, forging, quenching grinding, the crack caused by labor and slag, such as the location, shape and size of very fine defects.
