With the development of the rail transit industry, higher requirements have been placed on the quality and efficiency of maintenance and repair of rail transit equipment such as railway vehicles. Industrial endoscopes have become an important testing tool in this field due to their non-destructive testing characteristics. Industrial endoscopes can be used for visual inspection of special environments such as rail transit-related containers, pipes, the inside of equipment that is difficult to disassemble, the inner surfaces of narrow gaps, or areas that cannot be directly observed by human vision. They are used in the development and manufacturing of rail transit vehicles. , maintenance testing, quality control and other aspects have applications, including the following four aspects.
1. Shock absorber spring inspection. In the railway section maintenance regulations and factory maintenance regulations, the inspection requirements for shock absorber springs are mentioned. The specific requirements are to check for cracks, wear and other conditions, and then weld them according to the maintenance regulations. Traditional inspection methods often require the disassembly of the spring, but using an industrial endoscope to complete this task requires only sending the endoscope probe to the part of the spring to be inspected, and the cracks inside the spring and the condition of the top of the spring can be observed. , avoiding the workload and economic costs caused by disassembly.
2. Gear box inspection. During the normal use and operation cycle of a locomotive, gear wear and poor meshing of the traction gearbox are relatively common problems. If not discovered early and properly handled, it may even lead to the gearbox being scrapped and derailed. The gearbox inspection can be easily completed by using an industrial endoscope. During the specific operation, you only need to insert the flexible guide of the endoscope into the tube, enter the inside of the gearbox through the oil volume observation port of the gearbox, and you can see very intuitively. It shows the condition of the gears inside the gearbox and whether there are foreign objects at the bottom of the gearbox. At the same time, the image recording function of the industrial endoscope can also be used to take pictures and archive them for further troubleshooting or for future comparison reference.
3. Hollow shaft inspection. During the operation of electrified high-speed trains, if the hollow shaft is found to have corrosion, rust, wear and other suspicious parts of damage through ultrasonic flaw detection equipment, an industrial endoscope can be used to penetrate into the hollow shaft for further careful inspection, so that the endoscope can be used The observation magnification effect of the mirror reveals tiny cracks. Similarly, inspectors can also use the image processing system of industrial endoscopes to shoot inspection videos and record the specific conditions of the hollow shaft for later defect re-inspection through computers to ensure more accurate inspection results.
4. Internal combustion engine carbon deposit detection. For diesel locomotives, industrial endoscopes can also be used for carbon deposit detection. If there is carbon deposit on the exhaust valve of an internal combustion locomotive diesel engine, it will reduce the effective power of the internal combustion engine and cause fuel consumption. The use of industrial endoscope inspection avoids the traditional tedious operation of disassembling a diesel engine. You only need to insert the endoscope into the cylinder for inspection. The entire operation process is simple and easy.
In recent years, with the operation of petrochemical equipment, the extension of maintenance cycles, the expansion of production scale, and the continuous development of new processes, the complex process environment has placed higher and higher requirements on detection products. Endoscope inspection is an inspection technology that has gradually been widely used in recent years with the development of industrial endoscope production and manufacturing technology. Through the inspection of industrial endoscopes, workers can detect the size and size of defects in pressure vessels and pipeline welds. Defect characteristics can be accurately judged. Through regular inspection, staff can promptly discover whether there are new defects during use, so that staff can be promptly reminded to repair the equipment to achieve the purpose of equipment and personnel safety.
2. Classification of industrial endoscopes
In terms of materials, endoscopes can be divided into two types: rigid tube type and flexible endoscope, also known as rigid endoscopes and flexible endoscopes.
1. Rigidity
The endoscope consists of three parts: image transmission, lighting, and stoma. The image transmission part is divided into objective lens, relay system and eyepiece to form the transmission image. The lighting part adopts the method of penetrating the cold light source into the interior with optical fiber. The function of the stomata is to supply air, water, and pass the biopsy forceps.
2. Softness
Endoscopes that use fiber beams to transmit images and guide light or use CCDs to transmit images are called flexible endoscopes. Because of its good softness and convenient operation, the characteristics of soft endoscopes are: it can be easily entered and can reach places that rigid endoscopes cannot reach. Coupled with the head curved structure, blind spots can be eliminated. Samples and treatments can be taken through the biopsy hole. Flexible endoscopes can be divided into fiber endoscopes and electronic endoscopes.
Because industrial endoscopes can expand the detection range of inspectors, improve detection safety, and avoid equipment damage caused by disassembly, they are widely used in quality inspection, security, flaw detection, and troubleshooting in many industrial industries. More and more companies are buying industrial endoscopes. Since the price of industrial endoscopes varies greatly, many people focus on the price when purchasing, while ignoring many other important factors. The later use of industrial endoscopes brings a lot of unnecessary trouble.
When purchasing industrial endoscopes, besides price, what other factors should you pay attention to? Here we mainly remind you of two aspects: product technical indicators and after-sales service. We hope to help you choose good quality industrial endoscope products and use them with confidence.
