For a long time, countries have been paying a lot of painstaking efforts to study the safety of wire rope. At present, the internationally recognized wire rope detection method is nondestructive testing based on magnetic flux leakage and main magnetic flux. However, on the market, nondestructive testing products are mixed. How should we choose testing equipment with practical significance and equip wire rope with very reliable and professional "physical examination doctors? Below I will introduce to you in the choice of wire rope NDT detector common misunderstanding.

Common Misunderstandings in Selecting Wire Rope NDT Detector

Myth 1: Is it true that they can achieve "three fixed" as they say?

At present, all the wire rope NDT detectors that can be found on the market, of course, most of the equipment manufacturers are mainly selling equipment. Almost all the equipment we can see claims that their home equipment can be qualitative, positioning, quantitative, and internal defects can be accurately determined, which has become a gimmick for businesses to sell equipment. This should be a very basic technical parameters of the testing equipment, but it is difficult for many manufacturers to achieve the goal, which is why the non-destructive testing technology of wire rope has not been widely used in China. When we choose testing equipment or testing institutions, we need to see whether it is really "three fixed" or fake "three fixed". Technical demonstration is necessary.

Myth 2: Can we rest easy when we buy the equipment?

First of all, we have to understand one thing, the accuracy of detection is a combination of multiple factors, not a single instrument can achieve. It is the result of the comprehensive action of equipment, testing personnel, testing process, installation method, and field conditions. Regardless of the performance of the wire rope NDT detector itself, different testing equipment will also have unused defects. Internationally, it is generally believed that the role of the equipment is only about 25%, and the remaining 75% is the knowledge, ability and experience of testing personnel. Due to the lack of accuracy and unprofessional on-site inspection personnel, there is no inspection time. After many customers buy the equipment, most of them are put on hold. This is what we need to think about, where is the significance of our testing? It may be that a professional testing organization is more practical than buying a testing device. What we need is accurate detection, and after accurate detection, we need to conduct a comprehensive analysis of the detection data and judge the deterioration trend, which is difficult for users to do.

Myth 3: Detection is not monitoring

Many equipment manufacturers are not based on the basis of detection, that is, accuracy, and turn to online detection as a propaganda point to cover up the disadvantages of the equipment itself. And this so-called "online detection" can not really realize the monitoring of wire rope, not only the accuracy can not be guaranteed, but also the equipment 24 hours on the work of the wire rope itself there is a huge security risk. As the publicity of online testing has a great impact on mine customers, when it comes to wire rope NDT detectors, everyone immediately thinks of online testing. This is a question that we often ask in the process of testing, and it is also a misunderstanding that we are relatively easy to step into in our current cognition.

These are some of the misunderstandings that we usually enter when choosing wire rope nondestructive testing. In recent years, wire rope non-destructive testing technology in the domestic mining industry has developed rapidly, the domestic mining industry wire rope non-destructive testing into the "hundred schools of thought contend" era, for the wire rope to choose the right medical doctor, is to ensure the safety and economic production of the premise.
