Magnetostrictive Displacement Sensor Used On Sanding Rail

With the rapid development of the city, kinds of rail transit have been vigorously developed. High-density train operations such as high-speed rail and subway have brought higher track wear rates, and at the same time put forward new requirements on the quality and ability of track polishing. Rail grinding technology can not only ensure the running quality and safety of rail vehicles, but also effectively increase the service life of the rails and reduce operating costs.The rail grinding machine adopts various modes base on different rail defects to quickly polish the rail wave wear, rail fat edge, saddle wear, weld depression and fish scale cracks to eliminate rail surface irregularities, rail head surface defects and other defects. Restore the rail head contour to the design requirements, so as to reduce the defects, improving the smoothness of the rail surface, and further improving the comfort, reducing noise, and extending the service life of the rail.

The profile of the rail head is similar to an arc shape, but the actual polishing is to divide the rail head into different areas according to the angle, that is, the rail head profile is regarded as composed of line segments divided by angles, and the position that needs to be polished corresponds to a certain angle.

It is not difficult to find that the accuracy and reliability of the displacement sensor directly affects the working quality of the rail grinding machine. Soway magnetostrictive displacement sensor has a wide range of applications in the rail grinding machine, and its accuracy can reach up to 0.1mm, which is suitable for rail transit equipment maintenance. Its fully built-in installation can withstand harsh working environments and has a higher level protection.
