Nondestructive Testing of Jichai Diesel Generator Set

The physical inspection of Jichai diesel generator set is to determine the technical state by using physical quantities such as electricity, magnetism, light, sound and heat, and to find internal defects through changes in components. It will not cause damage, separation or damage to the parts of Jichai diesel generator set. At present, this method is generally called nondestructive testing of Jichai diesel generator sets. For maintenance, this monitoring mainly includes regular inspection, maintenance inspection and operation inspection of spare parts.

It is also called magnetic flaw detection to judge whether there are cracks, cavities, uneven structures and other defects in the parts of Jichai diesel generator set by using the situation that the magnetic force line of Jichai diesel generator set passes through ferromagnetic materials. The principle of this method is to magnetize parts by inducing the magnetic field of strong DC inductance of Jichai diesel generator set. When the magnetic field of Jichai diesel generator set passes through permeable materials, the magnetic line of force will pass through in the shortest straight line.

If the internal structure of the parts of Jichai diesel generator set is uniform, the direction of the magnetic line of force passing through the parts of JICHAI diesel generator set is uniform. If there are defects in the parts of JICHAI diesel generator set, the defective parts will form large magnetoresistance. The magnetic field line will change direction, bypass the defect, gather around the defect, and expose a leakage magnetic field similar to the surface defect of the part.

When the iron powder of Jichai diesel generator set is evenly sprayed on the surface of the parts, the iron powder is adsorbed on the edge of the defect, thus showing the location and size of the defect. This method has the characteristics of high sensitivity, simple operation, fast and so on, but it is only applicable to the magnetizable parts of Jichai diesel generator set. On the surface of the parts of Jichai diesel generator set, if the defect depth of Jichai diesel generator set is deep, it is not easy to detect, Magnetic testing is widely used in production units.
