The importance of industrial endoscope in aircraft troubleshooting

Analyze the importance of industrial endoscope in aircraft fault diagnosis and troubleshooting.

Any failure or potential failure of the aircraft is a serious threat to flight safety, so it must be treated with caution. Even if it is only suspected that an unknown object (such as a small piece of debris) enters the aircraft engine, a comprehensive inspection should be carried out, especially inside the engine. According to the requirements of aircraft maintenance manual and airworthiness instructions, industrial endoscopy is often required, which is a very intuitive detection method to clarify the status of aircraft.

       With the development of manufacturing technology, endoscopic inspection technology has been widely used in many fields, such as pressure vessels, industrial pipelines, reactors, heat exchangers and other welding internal surface quality, which are the inspection objects of industrial endoscopes. In the aerospace field, it is used to check whether turbine engine blades are damaged, which is faster, more accurate, and efficient than traditional hand touch and visual inspection.

       It is naturally unwise to disassemble the engine without identifying the fault. The interior of the engine can be observed without disassembly using an industrial endoscope. The process is also a challenge for inspectors. It is necessary to find the damaged area through some recognizable traces (such as bolts and nuts) under the guidance of the detection image. A good industrial endoscope can play a better auxiliary role.

       For example, JEET JX series motor-driven 3D measurement videoscope has image processing capabilities such as automatic light output adjustment lighting system, adaptive noise reduction, and dark enhancement, so that it can perform stably under variable detection conditions. Whether in dark or reflective or looking for small defects in a wide range of living areas, inspectors can find traces of defects or faults in clear images. The equipment also has the 3D measurement function of the dry phase scanning technology, which can accurately measure a series of defect characteristics.

        After the endoscopic inspection of aircraft components, a detailed inspection report will usually be issued, including the description of the detected defects or faults, as well as high-quality inspection images and video data. The inspectors will make the final decision based on this information, often with three results: the aircraft could continue to fly after being released, would be authorized to fly back to the base for maintenance, would be replaced the engine.

        The maintenance cost of aircraft engines may exceed one million dollars, and the cost of replacing engines is more expensive. Therefore, inspectors need to produce accurate and visual fault evidence, which will affect whether they can make wise decisions. Industrial endoscopes can achieve this goal, which also highlights the important role of industrial endoscope in aircraft fault diagnosis.

       Application of industrial videoscope technology in Aeroengine

     In the aerospace field, industrial endoscopes have been widely used in the aerospace field, mainly to detect turbine blades, combustion chamber cracks, find and remove excess materials in the fuselage frame, weld various oil pipes and other cavity surface defects and other pipe surfaces, surfaces, engine cylinder barrels, oil pipes, oil pressure parts, nozzle components, etc. Compared with other detection technologies, the technology of detecting aircraft engine faults with industrial endoscope is relatively simple. The system uses the endoscope probe to transmit the image inside the engine to the external display. The crew judges the fault according to experience and the engine maintenance manual.

The endoscope in aviation is mainly used for quality control of research, design and development, manufacturing, assembly, internal structure welding of aero-engine, inspection of sanding, burr and wrong hole of castings, and defect troubleshooting of key parts such as flight navigation system.

The industrial endoscope products of Shenzhen JEET Technology Co., Ltd. mainly involve the R&D, manufacturing and maintenance of aerospace products; Automobile research and development, production, sales and maintenance; Military industry and security; Track design and manufacturing technology and management of oil and gas chemical industry, ships and railway locomotives; Maintenance of fire system pipelines and sewers. Welcome to inquire about the latest industrial endoscope products in our industry.


Engine maintenance

Turbine cleaning, blade and nozzle / nozzle blockage inspection, recovery of fallen parts, internal and external corrosion of pipelines, main steam pipelines, water supply heaters, condensers, wind turbines, blade operation status, refining / oil transmission lines and sealing systems, valve base inspection, turbine / generator / generator, generator stator inspection, blade inspection.

Aerospace Industry

Routine maintenance and inspection of large diesel engines, various engines and pipelines in railways and ships. It is used for regular inspection of aircraft turbine, blade, engine, weld surface, duct surface, combustion chamber interior or body inspection, as well as research, development and manufacturing of rocket engine.

Petrochemical industry

There is no need to disassemble the tested equipment in the testing process, so it is a very cost-effective testing solution. Especially in the detection and inspection of internal defects such as storage tanks, heat exchangers, spherical tank trucks in petroleum refineries, pipeline facilities in the chemical industry, special inspection stations and pressure vessel production units.

Automobile manufacturing, means of transportation

Endoscope is also an indispensable daily tool in the cleaning and maintenance of automobile engine. At the same time, it is simple, flexible, compact and easy to carry. The soft, small and flexible insertion tube can reach any hidden part that needs to be checked. Automobile endoscope is widely used in automobile production and maintenance industry. It is mainly used to detect and diagnose the wear, carbon deposition and blockage of automobile engine, cylinder, oil pressure parts, fuel pipe, engine, muffler, transmission and air conditioning system, differential, water tank, oil tank, gearbox, etc., which improves work efficiency, reduces repair costs, and avoids the damage caused by repeated disassembly and assembly of parts.

Locomotive, engineering, pharmaceutical, food pipeline

In railway / ship,inspection camara is used to inspect electric locomotive, air conditioning system, turbine, heater, diesel engine, boiler flame and pipeline. Construction engineering is used to check the corrosion and dirt of steel pipes, internal diagnosis of walls, rust of reinforcement, cracks of support shafts and bridge joints, etc. it can also be used to observe the cavities inside the tunnel and building models; Diagnosis of corrosion and blockage of tap water drainage pipe. Research institutions are used for observation, scientific research, laboratories, archaeology, etc. of research institutions.

Development trend of industrial endoscope

Industrial endoscope technology has unique advantages. It can extend people's sight distance, change the direction of sight at will, and accurately observe the real condition of the inner surface of the object, which cannot be replaced by other detection instruments. For example, in the application of aviation, the industrial camera/videoscope can be extended into the interior of the aircraft engine to directly observe the real internal condition or the internal surface condition of equipment parts after operation; Effectively detect the surface condition of concealed or narrow parts without disassembling the equipment or components for destructive inspection. The method is simple, reliable, intuitive and effective. Whether in the field of aviation, aerospace, electronic industry and other manufacturing In 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, local enlargement, clear graphic and integrated report output, etc.
