Application of industrial endoscope in nondestructive testing
Industrial endoscope is used in NDT (non-destructive testing) work, now it has been welcomed by industrial manufacturing and maintenance industry. In the 1970s, endoscopy was used as an important instrument for NDT detection in civil aviation aircraft maintenance in China. In the mid-1980s, this product was also used in NDT work in pressure vessel, petrochemical, electric power, machinery manufacturing, ordnance and other industries. At present, the use of this product in our country belongs to the medium level, the development potential is great, and it needs to be further promoted.
Industrial endoscope technology has unique advantages, it can extend people's sight distance, and can arbitrarily change the direction of the line of sight, accurately observe the real situation of the inner surface of the object, which can not be replaced by other detection instruments. For example, in the application of aviation, the industrial endoscope can be extended to the interior of the aircraft engine to directly observe the real internal condition or the internal surface condition of the equipment parts after operation; the surface condition of the relatively hidden or narrow parts can be effectively detected, without the need to decompose the equipment or parts for destructive inspection. The method is simple, reliable and effective. In the field of Aeronautics and Astronautics, whether in the manufacturing industry or the maintenance industry, the use of endoscope for NDT detection has achieved good results, solved many difficult problems, ensured the normal operation of the whole set of equipment, and avoided some accidents. Now the application of industrial endoscope technology has developed to the use of computer image processing technology, printing technology and network technology to complete the capture, storage, processing and analysis of images under endoscope, the writing of standardized reports, advanced document management, accurate image measurement and analysis, partial magnification, and clear integrated report output. At present, compared with foreign similar products in China market, the application level of domestic endoscope products is in a leading position.
