Endoscope products were imported from abroad in 1970s and 1980s in China, which were mainly used to control the internal allowance of aerospace products and check the quality of some parts. There are many kinds of instruments now, and industrial endoscope is one of them. In recent years, domestic endoscopic inspection has entered the practical stage, and has been increasingly applied to the quality control of product production process, and has developed into a routine inspection method. The types of industrial endoscopes in this section are divided into optical mirrors, fiber optic mirrors and electronic mirrors according to the imaging forms. Optical mirrors transmit the images of internal objects to the eyes of the detector completely through light without distortion, so the imaging is very fidelity and the definition is the highest among these mirrors. The principle of fiber optic mirror is similar to that of optical mirror. In order to enter a smaller hole, we choose a fiber mirror. The clarity of fiber optic mirror depends on the number of fiber bundles. Electronic endoscope shoots the inner surface of an object through a CCD camera and then displays it through a video terminal. Classification 1. Video electronic endoscope adopts digital color CCD imaging device, which has the characteristics of clear image, stable performance, convenient operation and wide application range. But the price is higher, which is generally used by automobile manufacturers and even the aircraft industry. The second is the optical fiber endoscope, which observes the internal situation of the engine through the eyepiece. Maintenance workers use their eyes to visually inspect, and work is easy to fatigue; 3. Fiber endoscope+special interface+digital camera can directly check the internal situation of the engine on the display screen of the digital camera, and can shoot the observation results at that time, and its price is also very reasonable. Edit the nondestructive testing principle of industrial endoscope in this paragraph. Industrial endoscope is a branch of nondestructive testing, and it can also be said to be a special testing technology. Because of its special size design, industrial endoscope can simply and accurately observe the internal surface structure or working state of the object without destroying the surface of the object to be detected. Non-destructive testing needs to use industrial endoscope as a testing tool, which is specially designed and produced to meet the complex industrial use environment. Endoscope detection is a widely used detection technology with the development of endoscope manufacturing technology in recent years. According to the characteristics of manufacturing technology, we generally divide industrial endoscopes into three types: optical hard tube mirrors, optical fiber mirrors and video mirrors. Industrial endoscopes can be used for inspection and observation of high temperature, toxicity, nuclear radiation and places where human eyes can't directly observe, mainly used in automobiles, aero-engines, pipelines, mechanical parts and so on. Non-destructive testing can be realized without disassembling or destroying components and stopping the operation of equipment. On the other hand, industrial endoscopes can also be connected with cameras, video cameras or electronic computers to form cameras, video cameras and image processing systems to monitor, record, store and analyze visual field targets. Editing this paragraph of industrial endoscope products Industrial endoscope adopts the internationally advanced manual lever technology, which can realize 360-degree omni-directional rotation of the probe and can correspond to any complex detection environment. Moreover, the oil-proof and waterproof design of the product can reflect its excellent detection function whether underwater or in the pipeline. Industrial endoscope products are small and portable, integrating the functions of taking photos and recording, and have the functions of taking photos, flashing and digital zooming. So that the measured object can be presented more clearly. It integrates the functions of temperature display, high temperature alarm, simple and convenient data storage, multi-mode selection, recording, and marking the measured part by audio.

The image is clear, the operation is simple, the effective detection distance is far, the application range is wide, and it can be connected with a computer to realize storage. It is a shining star in today's industrial endoscope detection industry! Edit the characteristics of the industrial endoscope in this paragraph ● Rugged and durable: the cables and rods of the industrial electronic endoscope are basically metal.

It integrates optical, mechanical, electronic and image processing software. The industrial endoscopy instrument is equipped with a high-resolution color display or a notebook computer with USB port, which is more convenient to carry, clearer to observe images and convenient for operators to use high-definition color CCD. The observed doubtful points and flaw detection parts are frozen, amplified, analyzed, measured and printed with the help of a unique professional software processing system, which greatly improves the accuracy of judging the flaw detection parts of the inner wall of the pipeline.

Industrial video endoscope T922

The probe is designed as a direct-view lens and a side-view lens, which can scan and observe the pipe wall 360 degrees and is convenient and reliable to use. For example, it is necessary to detect defects and inspect and maintain important equipment, such as turbines, pipelines, condensing pipes, pumps, boilers, heat exchangers, valves, pressure vessels, etc. And the equipment inspection of nuclear power plants, wind power plants, hydropower plants, thermal power plants and electric power construction units is even more indispensable. Industrial endoscopes for precision casting and mechanical manufacturing can be used in automobile parts casting, hydraulic casting, pump body and valve body casting, mechanical parts casting, pipeline and pipe fitting casting units, and can be used to check the quality control of sand inclusion, burrs and staggered holes in castings. For this kind of examination, the same three-dimensional endoscope is small and flexible. For the inspected parts, the hole ratio is small and the lens rod is small, so it can be inserted flexibly and easily; The video display is also very intuitive and clear, and the deep holes, blind holes, staggered holes, Gaza and burrs in casting can be seen at a glance. Automobile maintenance and production industries Industrial endoscopes are widely used in automobile production and maintenance industries, mainly used to detect and diagnose the wear, carbon deposition and blockage of automobile engines, cylinders, hydraulic components, fuel pipelines, engines, silencers, transportation and air conditioning systems, differentials, water tanks, oil tanks and gearboxes, which improves work efficiency, reduces maintenance costs and avoids damage caused by repeated disassembly and assembly of parts. Endoscope is also an indispensable daily tool in automobile engine cleaning and maintenance. At the same time, it is simple and flexible, small and easy to carry, and the soft, small and flexible insertion tube can reach any hidden part that needs to be checked. T922 industrial endoscope used in aerospace industry can be used for regular inspection of aircraft turbine, blade, engine, weld surface, duct surface and combustion chamber, or inspection of engine body, as well as research and development and manufacture of rocket engine. Aircraft maintenance can not be separated from endoscope, which is called "hole finder" and is one of the five tools for daily maintenance and routine inspection of aircraft. Its purpose is to master the internal situation of the engine. As the only inspection method in airline maintenance that can understand the internal condition of the engine without disassembling it, endoscopic inspection is of great significance and value for safety and benefit: first, it is intuitive, accurate and simple, and it can find the damage of the internal components of the engine as soon as possible, which is greatly conducive to eliminating potential safety hazards in the bud; Secondly, endoscopic inspection avoids the cost of disassembling the engine and the corresponding engine, unnecessary losses in transportation and aircraft shutdown, and saves maintenance costs. Three-dimensional industrial endoscopes in petroleum, chemical and pressure vessel industries can be used for internal defect detection and inspection of storage tanks, heat exchangers, spherical tanks, pipeline facilities in chemical industry, special inspection institutions and pressure vessel production units in petroleum refining enterprises. At the same time, there is no need to disassemble the detected equipment in the detection process, which is a very cost-effective detection scheme. Video endoscope technology has been widely used in internal inspection, weld inspection, pipe wall deposition, corrosion and crack detection, overheating detection, leakage detection, electroplating pipe and girth weld detection of industrial condenser pipes, compressors and heat exchanger pipes. The video endoscope's own image processing system and recorder can effectively record, store and process inspection defects at any time to ensure the archiving of image data. Industrial video endoscopes, pipeline endoscopes and straight-rod endoscopes introduced by industrial endoscopes in railway buildings, ships and scientific research units are widely used in many different factories and mines. Used for railway/ship units to inspect electric locomotives, air conditioning systems, turbines, heaters, diesel engines, boiler flames and pipelines; It can be used in construction engineering units to check the corrosion and dirt of steel pipes, the internal diagnosis of walls, the corrosion of steel bars, the cracks in the joints of supporting shafts and bridges, etc. It can also be used to observe the cavities inside tunnels and building models; Diagnosis of corrosion and blockage of tap water drainage pipe: used in scientific research institutions for observation, scientific research, laboratory, archaeology, etc. Industrial endoscopes for national defense and military security and security inspection have also been used in weapons manufacturing, daily maintenance, security, customs inspection, search and rescue, life detection and other fields. Weapon manufacturing is used to check the wear, looseness, oil leakage and the internal condition of the barrel of the machine. Security inspection is used by public security and customs departments to check hidden drugs and smuggled goods. Search and rescue detection is used for earthquake search and rescue, emergency search and explosion-proof inspection. Power production and construction units and three-dimensional industrial endoscopes are used in various power plants/power construction units to build and inspect important equipment such as steam turbines, pipelines, condensing pipes, pumps, boilers, heat exchangers, valves, pressure vessels, etc., to detect defects and monitor working conditions. Application parts: find out the internal and external corrosion of the dropped parts. Turbine cleaning blades and nozzles are blocked. Check the valve seat and sealing system of oil refining/oil pipeline. Check the main steam pipe, feed water heater, condenser, wind generator/generator, generator stator, and check the blades. Industrial endoscope can effectively improve the problems existing in various equipment and check the quality defects such as corrosion, rust spots, cracks, iron filings and butt welds in parts. The compactness, portability and mobility of the instrument itself can reduce the working intensity and improve the working efficiency. Portable batteries are more convenient to work in narrow spaces, high-altitude climbing, field work and other harsh environments. Edit the development trend of industrial endoscope in this paragraph. Industrial endoscope technology has unique advantages, which can prolong 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 is irreplaceable by other testing instruments. For example, in aviation applications, the industrial scope can be extended to aircraft engines, and the real internal situation or the internal surface situation of equipment parts after operation can be directly observed; The surface condition of relatively hidden or narrow parts can be effectively detected without disassembling equipment or parts for destructive inspection. This method is simple, reliable, intuitive and effective. Whether in the aerospace field, electronic industry or other manufacturing and maintenance industries, the use of endoscope for nondestructive testing has achieved good results, solved many problems, ensured the normal operation of the whole set of equipment and avoided some accidents. At present, the application of industrial speculum technology has been developed to complete the collection, storage, processing and analysis of endoscopic images, the writing of standardized reports, advanced document management, accurate image measurement and analysis, local amplification, and clear integrated report output. The minimum diameter of industrial endoscope camera CCD and optical fiber contrast monitoring analog camera can reach 4 mm, which is very different from traditional optical fiber endoscope. Due to the limitation of its own structure and principle, fiber-optic endoscope can not display in full screen, and the image is composed of grids, which generally does not exceed 654.38+ ten thousand pixels; The monitoring analog lens does not have these shortcomings, and the high definition can reach 500,000 pixels (720X682). In addition, the proper clear sight distance makes it especially suitable for industrial applications.
