Types and characteristics of wire rope nondestructive testing instrument

　　Wire rope nondestructive detectorThe types are roughly divided into four types, each with different characteristics. The following is a small series of Baikette to introduce the characteristics of each device in detail.

1. Simplification of instruments and equipment

This kind of equipment is simple to operate and basically does not have too high requirements for personnel, which is more suitable for on-site rope inspection personnel. The equipment has high detection efficiency, low detection precision and accuracy, and cannot give detailed detection data of the whole rope. It can only give simple damage or defect statistics to assist rope inspectors in finding suspicious damage, and cannot accurately quantify and analyze the nature of damage. This kind of wire rope nondestructive detector can only remind the rope inspection personnel to pay attention to the final degree of wire rope damage to the need for manual verification and confirmation. Therefore, this type is called electronic monitoring type, also called fool type. However, at present, such equipment has a defect that the alarm threshold is not well set. It is easy to lead to false alarms and false alarms.

2. Intelligent instruments and equipment

This kind of wire rope nondestructive detector through the computer to detect, store and analyze the test data, the operation is relatively complex, there are certain requirements for personnel, the use of personnel need to learn how to analyze the test data. This kind of equipment is more suitable for rope inspectors with certain computer knowledge. It has high detection efficiency, high detection accuracy and accuracy. It can give detailed detection data of the whole rope, automatically generate detection reports, and give statistical data of damage or defects. The equipment has strong analysis function, which can quantitatively detect the loss of metal cross-sectional area of wire rope and quantitatively analyze broken wire. According to the development trend of the detection curve, the speed and trend of the development of wire rope damage can be analyzed, and the service life of the wire rope can be accurately predicted.

3. Networked instruments and equipment

This kind of equipment carries out remote centralized management and centralized detection of steel wire rope through the network, and takes the steel wire rope detection as a part of the whole equipment monitoring, which improves the safety of the whole steel wire rope non-destructive detector. This kind of equipment is equivalent to a pre-intelligent instrument of the monitoring system. Need to detect when connected to the network can be detected. Computer knowledge and network knowledge are required to operate this equipment. The operation of the instrument is relatively simple, and the analysis and processing are similar to those of intelligent instruments. At the same time, it also has the characteristics of simplifying the instrument.

4. Multi-functional instruments and equipment

This kindWire rope nondestructive flaw detectorUsing a variety of sensors and a variety of ways to detect as much as possible to reflect the damage of the wire rope information, through different methods and different sensors complementary advantages, learn from each other, as far as possible a comprehensive reflection of the damage of the wire rope, to make up for the limitations of the instrument, so as to achieve scientific and accurate detection of the wire rope. At present, only foreign countries have such instruments. Domestic has not yet developed such equipment.
