With the continuous development of modern manufacturing technology, industrial endoscopes have become compact and lightweight, which is very suitable for working in complex environments such as the wild. Industrial endoscopes are increasingly used in industrial production processes and equipment maintenance processes. in. The main purpose of industrial endoscopes is to test industrial equipment and equipment. Today, Xiaobian will talk about the principle, classification and purchasing skills of industrial endoscopes.
　　 Industrial endoscope principle
The industrial endoscope consists of a cold light source, a fiber optic tube and a fiber optic endoscope.
The cold light source is composed of a transformer, a pressure regulating device, a cooling fan, a metal iodine tungsten lamp, a mirror coated with a luminescent material, and a set of lenses. When the power is turned on, the metal iodine tungsten lamp is turned on, and the light-emitting intensity can be adjusted by the voltage regulating device.
The cold light mirror reflects the cold light onto a set of lenses, and after focusing through the lens, the light reaches the light guide hole.
The endoscope consists of an eyepiece, an objective lens, and a light guide. The image beam and the guiding beam in the light guiding tube are composed of tens of thousands of fine glass fibers. When the fiber optic hose transmits light from the source to the endoscope, the light passes through the beam to the viewing point inside the machine. The objective lens mounted on the head of the light guide tube transmits the geometry and color inside the machine to the eyepiece through the image beam and magnifies the image.
　　 Classification of industrial endoscopes
Industrial endoscopes can be classified according to the form of imaging: industrial optical fiberscopes, industrial optical straight mirrors, industrial video endoscopes.
The industrial optical straight mirror axis is equipped with an image transmission system composed of many optical lenses, which can obtain higher quality images, which are actually transmitted to the eyes of the examiner, and the imaging is very fidelity and high definition.
The industrial optical fiberscope can deeply inspect the unreachable position of the industrial optical straight mirror. The biggest difference between it and the optical straight mirror is the use of soft optical fiber to form an image transmission system. Once the light enters the fiber, it cannot escape. Therefore, the industrial optical fiber The twisting or bending of the mirror axis does not affect the image transmission; since the image is composed of the same "point" as the number of fibers, that is, the image resolution is determined by the number of fibers; the larger the diameter, the higher the imaging resolution of the fiber. .
The industrial video endoscope directly takes images from the sensor chip and transmits them to the monitor image through the signal transmission line. The LED is directly illuminated on the shaft end, and the image is observed on the screen, and the photos and videos can be stored.
　　 Industrial endoscope shopping tips
　　 1. Technical elements such as quality parameters and process level of the product itself:
Some new brands or small brands do not have the core technology and production process for producing industrial endoscopes themselves, but in order to produce products that are not profitable or have good quality, such equipment has no quality and technical guarantee. The parameters are not up to the requirements, can not adapt to the use of the environment, lack of original accessories for replacement, the user experience is very poor. Therefore, equipment quality is the primary factor in choosing an industrial endoscope brand. In addition, attention should also be paid to the multi-faceted inspection of the technical aspects of detection environment, resolution, lighting technology, portability, and process.
　　 The following are explained separately:
　　 Detection environment: Determine the length and diameter of the endoscope lens required by the diameter and length of the detection site. Whether it has ultra-small diameter and ultra-long pipeline to meet various detection conditions. Whether it has a powerful guiding function, the probe can achieve 360° arbitrarily curved. Whether it is waterproof, oil-proof, durable, and passed the fall test.
　　 Resolution and Pixel: Whether it has excellent image processing technology, whether it has delicate images and true colors;
　　 Lighting technology: Whether the lens is illuminated determines whether it can be reused in a dark environment, and the wide angle of the lens and the lens diameter have a certain influence on the coverage of the field of view. Super light, super large viewing angle and multiple depth of field, all users can get a good testing experience;
　　 Portability: Whether the design of the all-in-one machine is adopted, it is convenient for users to carry into various harsh industrial environments;
　　 Process: The purpose of the product is to meet the needs of customers. The quality of the process requires sufficient professional knowledge to identify. The customer faces a huge ocean of information, and it is impossible to spend a lot of time on the process identification. Customer neglected.
　　 2, is equipped with relevant professional and technical personnel
Professional business people and technicians are key factors in getting the best solution. A large number of domestic production companies only focus on recruiting sales personnel, but often do not have too high technical requirements, and do not do related product and technical training. In the face of customers, it is often impossible to correctly understand the customer's intentions, answer the questions raised by the customers, and even provide better solutions, so that the problems cannot be solved. Therefore, the configuration of a company's professional sales staff and technicians is also a necessary condition for choosing an excellent industrial endoscope brand.
　 3. Is there a professional after-sales service?
High-quality industrial endoscopes, even if they are high in technical content, reliable in quality, and user-friendly, however, in the face of extremely harsh environments, there may be various unexpected situations, which requires good After-sales system. On the one hand, professional technicians with sufficient industry knowledge and product knowledge are required to inspect and repair equipment, and at the same time have sufficient spare parts inventory to replace parts. After-sales service includes not only equipment repair and maintenance, but also technical training. Communicate the latest industrial endoscope technology concepts to customers and use precautions to reduce human-induced equipment failure. Whether the company can provide a variety of contact channels, 24-hour hotline, online customer service, WeChat/QQ, etc., allows customers to contact relevant personnel as soon as possible, so as to get answers quickly.
Industrial endoscope principle, classification and purchasing skills are introduced so much. As a non-destructive testing tool, industrial endoscope has the characteristics of clear image, stable performance, convenient operation and wide application range. It has been widely used in various fields. Such as power, aviation, construction engineering, petroleum and petrochemical, automotive and other fields, of which thermal power vehicles and nuclear power plants are also one of the application areas.
