A pipe endoscope is also called a poroscope. The main function of the pipeline endoscope is to explore the position where the deep part of the curved pipeline can be observed, but cannot be seen directly. It can observe its internal structure and condition in the sealed cavity, not only to achieve long-distance observation, but also to achieve close operation. In fact, the insistence of endoscopy is to use endoscopy to inspect the inner surface of container, rolling belt, non detachable equipment and narrow gap. Or water and other liquid level and other special, human vision can not directly observe the area of quality inspection and visual inspection method.
Domestic pipe endoscopes were introduced from abroad in the 1970s and 1980s. At first, they were mainly used in aviation, aerospace and other important fields to inspect the quality of products and some parts. With the development of the country, the continuous progress of science and technology, domestic endoscopic technology has also been rapid development, today's endoscope products are various, and also entered the practical stage. Pipeline endoscopy technology has gradually developed into a more conventional detection method.
Pipeline endoscope is a new type of high-tech product designed and produced according to the inspection requirements of the inner surface of straight pipeline in petrochemical industry, industrial machinery, electronic and electrical industry, aerospace and other industries. It is one of the nondestructive testing tools. Compared with destructive testing, its advantages bring us a different feeling. In the automotive field, it can be mainly used in the automotive engine, fuel tank, brake system and other places that can not be directly seen by the naked eye. Through its detection, it can find out whether the engine product is qualified or whether the internal carbon deposition and damage of the automotive engine and other problems.
In the aviation field, it is mainly used to inspect the working cavity, weld surface, pipe surface, blade, turbine, combustion chamber and other parts of the aircraft engine, as well as the cylinder, fuel pipe, oil pressure parts, nozzle parts of the engine; In the field of underground pipeline, industrial endoscope has changed the traditional manual operation mode. Through its effective detection, it can not only effectively prevent the workers from encountering the safety accident caused by biogas, but also avoid the error of manual visual observation; In the railway industry, it involves the development, manufacture, maintenance and inspection of railway engineering vehicles and transport vehicles. Even in the process of railway infrastructure construction, such as the construction of bridges and tunnels, industrial endoscope detection is needed.
