Video endoscope is one of the important ways of nondestructive testing

Issue Time:2022/05/20
At present, a widely used visual inspection instrument is video endoscope, which is also one of the important methods in nondestructive testing. It is usually used to observe the surface state, alignment of mating surface, signs of deformation or leakage, such as parts, components and equipment. There are two methods of visual inspection: direct visual inspection and indirect visual inspection. Direct visual inspection refers to the direct detection of the tested object with human eyes or a magnifying glass with a magnification of less than 6 times. Indirect visual inspection refers to the method of visual observation with the help of various optical instruments or equipment.

Video endoscope

The visual inspection adopts instruments or equipment, and the corresponding visual inspection instruments can be selected according to the specific of the tested object, including magnifying glass, reflector, video endoscope, welding inspection ruler, illuminance meter, etc. For example, if the defect size is small and cannot be directly confirmed with the naked eye, it can be observed with the help of a magnifying glass; The use of reflectors is mainly used when it is difficult to observe the angle directly; When detecting objects in confined space or at a long distance, video endoscope can be selected for observation. The principle of detection is mainly to use the reflection of light. It can be used between the detected object and the detected object, whether there is a direct channel or no direct channel.



The use principle of endoscope detection is simple, easy to master, economical and simple, and the operation is simple. It can be used for nondestructive testing in narrow spaces, such as the inner surface of small containers. It can be effectively tested with the help of auxiliary equipment such as video endoscope, and is not or rarely affected by the material, shape, structure, size and other factors of the tested object. Nowadays, with the development of technology becoming more and more mature, video endoscope has become the preferred tool for the eyes. For example, in the field of automobile maintenance, the faults such as carbon deposition, wear, abnormal noise and corrosion of internal components of the engine can be detected efficiently and intuitively.



To sum up, this is the introduction shared by the editor of Shenzhen JEET Technology Co., Ltd. that video endoscope is one of the important ways of nondestructive testing. I hope it will be helpful to you.
