Problems Existing in Local Wire Rope Detection Method

With the continuous development of society, the wire rope is also in constant development, the wire rope detection technology is what, the current situation is how.

The defects detected by local fault detection method include local deformation, broken wire and so on, which belong to short scale defects. The difficulty of the local fault detection method is the identification of broken wires of the wire rope, which uses the method of measuring the peak value of the magnetic flux.

From the nature of the wire rope, the detected magnetic flux leakage of a single broken wire depends on the distribution position of the broken wire, the length of the broken wire section, the wire diameter, the force situation, the wire rope twisting structure and many other factors. If the broken wire detected by the wire rope is on the outer surface and the amount is small, it is easier to judge.

However, if there are other situations of broken wires, it is difficult to detect steel wire ropes, such as: broken wires in different sections are too close to each other, there are several broken wires in the same section, the diameter of steel wire is too small, and the distribution of broken wires in the section is chaotic. The above situation makes the leakage flux detected by the wire rope non-destructive flaw detector does not show a deterministic change with the number of broken wires, which brings a large measurement error to the determination of broken wires. Therefore, there is a certain error in the local fault detection method, which makes it difficult to distinguish the broken wire.
