How to check that the wire rope meets the standard?
1、Check for corrosion:
The steel wire rope is made of stainless steel wire or high carbon steel, but if the quality of the steel wire rope is not good, such as the manufacturer replaces the steel wire with iron wire, it will rust. Therefore, it is necessary to check whether the wire rope is rusted every day. If found, not only stop use, but also report to the production department and purchasing department.
2、Check the degree of wear:
During use, the wire rope will be worn and the diameter will change. The maintainer should always measure the diameter of each section, especially the wear condition of the easy-to-wear equipment. If the diameter becomes larger
Many, more than 5% will have to be reported and disabled.
3、Whether there is broken wire or wear phenomenon:
If the wire rope is used for a long time, the wire will be broken and ground. If the wire is seriously broken, it needs to be stopped immediately. Judgment is standard, generally: the outer steel wire wear does not exceed its straight
40% of the diameter; no more than 2 within 6d of the length of the twisted wire rope, no more than 4 within the range of 30d; no more than 1 within 6d of the length of the double-twisted wire rope. No more than 2 in 30d.
For details, please refer to the manual or national standard.
4、Check the fastening of both ends:
The steel wire rope will be connected with the hook. When checking, be sure to check the fastening of the connection and check the firmness of the hook.
5、Check the shape of the wire rope:
After the wire rope is deformed, there will be kinks, flattening, extrusion of strands, bending, etc. If these conditions are found, further inspections should be made and scrapped in time. Description: wire rope
It must not be used after being scrapped.
6、Check the lubricating grease on the surface of the wire rope:
The maintenance of the wire rope is to apply lubricating grease, which plays the role of lubrication, anti-corrosion and anti-wear. When checking the wire rope, you must check the grease condition to ensure that the grease is stored.
In, there is no debris such as fines on the grease.
