Industrial endoscope is currently widely used in the field of industrial manufacturing and mechanical maintenance of a non-destructive testing equipment, it extends the visual distance of the human eye, breaking through the dead Angle of human eye observation, can accurately and clearly observe the internal machine equipment or parts of the internal surface of the situation, such as wear damage, surface cracks, burrs and abnormal attachments, etc.

It avoids unnecessary equipment decomposition, disassembly and possible parts damage in the inspection process, has the advantages of convenient operation, high inspection efficiency, objective and accurate results, and is a powerful tool for enterprise production process control and quality control.

For example, in aviation applications, the industrial speculum can be extended to the inside of the aircraft engine to directly observe the real condition of the interior or the internal surface condition of equipment components after operation; Effective inspection of the surface condition of hidden or narrow areas without the need to disassemble equipment or components for destructive inspection. 

The industrial endoscopes

Comparison of characteristics of three industrial endoscopes

At present, the commonly used industrial endoscope has rigid endoscope, flexible endoscope, electronic video endoscope three kinds, the basic configuration includes: an endoscope, a light source, a optical cable, the basic principle is to use the optical system will be inspected object imaging, and then transmitted through the image transmission system, in order to facilitate the human eye direct observation or display on the display, so as to obtain the required information.

However, the three have their own characteristics and common occasions, and their characteristics are compared as follows:

1.Rigid endoscopes

Rigid endoscopes have different visual directions and fields of view, which can be selected according to the requirements of the work. When the object detection requires different visual directions, such as 0°, 90°, 120°, the ideal viewing Angle can be obtained by changing different probes with fixed visual directions or using a rotary prism endoscope by adjusting the axial rotation of the prism.

2.Flexible endoscope

The flexible endoscope controls the bending guidance of the probe through the guidance mechanism, and can obtain one-way, two-way, or even up and down, left and right four-way guidance in the same plane, so as to combine any observation Angle to achieve 360° panoramic observation.

3.Electronic video endoscope

Electronic video endoscope is formed on the basis of the development of electronic imaging technology, representing the highest level of industrial endoscopy technology, both rigid and flexible endoscope technical performance, high imaging quality, and the image displayed on the monitor, reducing the burden of the human eye, for multiple people to observe at the same time, so that the inspection effect is more objective and accurate.

Industrial endoscope characteristics

Advantages of industrial endoscopes

Compared with human eye detection methods, industrial endoscopes have great advantages:

Non-destructive testing

There is no need to disassemble the equipment or destroy the original structure, and can be inspected directly with an endoscope;

Efficient and fast

the endoscope is lightweight and portable, easy to operate, and can effectively save time and improve detection efficiency for the occasion of rapid detection;

Video imaging

The inspection results of endoscopes are intuitively visible, and videos and pictures can be stored through memory cards to facilitate monitoring and control of product quality, safe operation of equipment, etc.;

Detection without blind spots

The detection probe of the endoscope can be turned at any angle at 360 degrees without any blind spots, which can effectively eliminate blind spots in the line of sight. When detecting defects on the inner surface of the object cavity, it can be viewed in multiple directions to avoid missed inspections;

Not limited by space

The pipeline of the endoscope can pass through areas that cannot be directly reached by humans or cannot be directly seen by sight, and can observe the inside of objects with high temperature, high pressure, radiation, toxicity, and insufficient light.
