Wire rope nondestructive flaw detector, an important test method
Release time:
2022-03-21
Electromagnetic detection method is a non-destructive and important test method, which can check the whole wire rope without damaging any structure of the wire rope. The effectiveness and reliability of the inspection have been greatly improved, and the operation is also very convenient. At present, the commonly used detection method is to detect by wire rope nondestructive flaw detector.

At present, the commonly used detection method is to detect by wire rope nondestructive flaw detector.
Elevator wire rope flaw detector is a set of flaw detection system designed and developed specifically for the elevator industry. Various damages occurred during the use of high-speed and large-diameter elevator wire ropes, such as broken wires, fatigue, corrosion, abrasion, crushing, and twisting
Bending deformation, etc., designed and manufactured for regular local flaw detection of consumable and vulnerable parts of wire ropes in service, suitable for carrying and holding, I .e. probing and leaving or easy temporary placement and easy transfer. Can accurately assess the safety status of elevator wire rope implementation, for the use
The unit provides scientific judgment and reliable guarantee.
The advantage of elevator wire rope nondestructive flaw detector is that it can firstly distinguish the damage types such as internal and external fatigue, corrosion, abrasion and broken wire according to the pattern recognition software. Secondly, its flaw detection is very accurate. The signal has an extraction distance of more than 30mm and a detection speed of 30 m/s. Moreover, it is now intelligent flaw detection, which can intelligently and automatically quantitatively distinguish, classify and count various internal and external damages and accurately evaluate the safety state of wire rope, at the same time, the Internet of Things, big data, cloud computing and other data information interconnection and analysis technologies are integrated to expand the security monitoring information from local to regional scale, and the distributed final information is integrated into the overall security information database to realize the "borderless" interconnection of security management.
In the daily operation of the elevator, the wire rope is inspected and repaired from time to time, which not only ensures the performance of the wire rope to meet the standard, but also ensures the safe operation of the elevator, but also helps to extend the working time of the wire rope, reduce the frequency of wire rope replacement, and reduce Economic cost. In addition to testing and maintenance, we should also pay attention to the external oil coating of the steel wire rope. Not only the external oil coating of the steel wire rope, but also the internal oil quantity should be guaranteed. Moreover, during the oiling process, it is necessary to ensure that the lubricating oil is maintained at about 60 degrees Celsius to ensure that the lubricating oil can enter the inside of the wire rope.
In general, the elevator traction wire rope nondestructive testing methods are mainly divided into visual method and electromagnetic testing method, visual method is a more traditional detection method has many disadvantages, is now commonly used wire rope nondestructive flaw detector, can be efficient and accurate positioning to wire rope broken wire, fatigue, corrosion, wear, crush and distortion and deformation, and the operation is also very convenient.
