Fluorescent magnetic particle flaw detector is an important means of flaw detection

In our country, locomotive is a very important means of transportation, locomotive crankshaft, connecting rod is the lifeblood to ensure the locomotive running process, is an important part to ensure the safety of locomotive. The inspection of these crankshafts and connecting rods is an indispensable inspection item for every vehicle. The fluorescent magnetic particle flaw detector introduced by the subsequent mobile magnetic particle flaw detector is an important means to detect the damage of locomotive crankshaft and connecting rod. It is one of the important contributions to ensure the safety of locomotive. The following is Kunshan Su magnetic fluorescence magnetic powder flaw detector manufacturer to introduce the working principle of the equipment.

The poor performance of the penetration detection line is a comprehensive factor, including the business capacity of the flaw detector, the daily maintenance and maintenance of the equipment. Therefore, in order to ensure the safe operation of vehicles, we must eliminate all hidden dangers and improve the quality of flaw detection.

There are many magnetic particle flaw detectors on the market in China, and the fluorescent magnetic particle flaw detector is operated by the fluorescent magnetic powder. Their accuracy is much higher than the general magnetic particle flaw detector, so the price is relatively high. However, in order to ensure the safety of locomotive operation and eliminate unnecessary hidden dangers, it is recommended to use fluorescent lamps. Magnetic particle flaw detector, can not be too small too big.

By using strong current to generate magnetic field, the exposed surface of the locomotive is fully magnetized in both the circumference and the longitudinal direction. At the same time, a mixture of phosphorus and water is sprayed on the surface of the crankshaft and connecting rod to make it adhere evenly. Due to the change in permeability, the magnetic field lines escape from the surface of the axis, forming local magnetic poles that allow extremely fine fluorescent magnetic particles suspended in the liquid to accumulate in the crack. Under the condition of dark room, under the action of long-wave ultraviolet (320nm, 400nm, central wavelength 365nm), the fluorescence effect can stimulate obvious fluorescence, and achieve the purpose of flaw detection and identification.

In many non-destructive testing equipment, magnetic particle detection machine can be said to be a more widely used testing tool, mainly due to its function and advantages. Many industries in our country are constantly using magnetic particle detection machine, so what are the functions of magnetic particle detection machine? Today in this chapter, Sheyang Chengyi flaw detection equipment and friends to understand and discuss, I hope to have some help for everyone to detect the quality of the workpiece.

Intelligent recognition digital system - it can clearly detect magnetic powder cracks, detect magnetic marks, and generate the same or clearer crack images. Especially for the problem of uneven gray scale of the image, the original image can be enhanced to save some useful information. The accuracy and accuracy of the test results are satisfactory.

Multi-stage fitting crack detection: The existence of cracks is assumed according to the properties of a column of cracks, and then possible crack pixels are extracted from the gray image, and then the cracks are fitted to identify the real cracks. The results show that the multi-stage fitting method improves the reliability, stability and universality of the detection.

PLC triggering technology - Closed-loop control by PLC and related devices, thyristor triggering technology, so that the current in the process of magnetic powder flaw detection can work reliably within the allowed range, to ensure the stability of the magnetizing current output, to improve the stability of the detection results.

Environmental acquisition and monitoring system - convert environmental variables into digital signals, identify and display them through calculation performance, and adjust the lighting of the detection time according to needs, so as to achieve automatic control of the magnetic suspension liquid level of the detection and improve the reliability of the detection.

Image monitoring and management - magnetic particle flaw detection machine adopts mature digital camera technology to collect fluorescent magnetic mark images, and real-time transmission, processing through computer software, image display, pre-processing, defect warning and local amplification, so that the entire detection process to achieve

automation.
