What danger does wear bring to the wire rope

Although the wire rope specifications, variety, the use of thousands of different, but generally with the use of time, there will be similar damage phenomenon. Common wire rope damage: wear, broken wire, corrosion, deformation, bite rope, overload and so on. Next, Baikete Xiaobian will give you a specific explanation of the wear and tearwire ropeWhat are the dangers?
The wire rope is in contact with other objects during work and has relative movement to produce friction. Under mechanical, physical and chemical action, the surface of the steel wire is constantly worn. Wear is a very common way of damage in the use of steel wire rope, which is generally divided into external wear, deformation wear and internal wear.
External wear: The wear caused by the contact between the outer surface of the wire rope and the surface of the wheel groove, drum, ground and other objects is external wear. The external wear is divided into two types: single-sided wear and overall wear. After the external wear, the rope diameter will become thinner, and the steel wire on the outer surface will be worn.
Improvement measures: When the wire rope is used for a certain period of time, the method of turning around and cutting the rope can be adopted to change the wear position, thereby prolonging the service life of the wire rope.
Deformation wear: due to vibration, collision caused by the wire rope surface damage, called deformation wear, which is a local wear phenomenon. If the wire rope on the surface of the drum is impacted by other objects, the wire rope strikes each other during lifting or the biting rope phenomenon caused by the deflection of the pulley and the drum center will cause the wire rope to deform and wear.
If the worn surface steel wire is cut, the cross section of the steel wire extends to both sides at the extrusion site into a wing shape. From the outside, the width of the steel wire is expanded. Although the cross-sectional area of the steel wire rope is not reduced much, the surface material of the steel wire at the local extrusion is hardened, which is very easy to cause the wire rope to break.
Improvement measures: reduce the collision of wire rope, often check and adjust the abnormal operation of wire rope and equipment, and repair it in time.
Internal wear: during use, all the load borne by the wire rope when passing through the drum or pulley is pressed on one side of the wire rope, and the radius of curvature of each steel wire cannot be exactly the same. due to the bending of the wire rope, each fine steel wire inside the wire rope will exert mutual force and slip. at this time, the contact stress between strands increases, causing local indentation or depression of the steel wires between adjacent strands. When repeated cyclic stretching and bending, stress concentration is generated in the depression and it is broken, which constitutes internal wear.
