Steam turbine is a kind of equipment that converts heat energy into mechanical energy, due to its working environment is mostly high temperature and high pressure and complex structure, it needs to use industrial endoscopes of special design and materials for internal inspection. A steam turbine industrial borescope is a device used to detect and observe the inside of a steam turbine. It can help inspectors understand the conditions inside the turbine by inserting a probe inside the turbine and transmitting the image from the inside to an external display.
The main functions of the steam turbine industrial borescope include:
1. Internal observation: By providing high-definition images or high-definition images, industrial endoscopes can help engineers and technicians observe the internal conditions of the steam turbine, including blades, rotors, steam chambers, combustion chambers, etc. By observing the conditions of these parts, it is possible to judge whether the operation status of the steam turbine is normal and whether there are faults or hidden dangers.
2. Defect detection: industrial endoscopes can help find defects inside the steam turbine, such as cracks, wear, corrosion, etc., so as to carry out timely repair and maintenance.
3. Image transmission: The steam turbine industrial endoscope transmits the image inside the steam turbine to the external display through high-definition camera and image processing technology, so that the inspector can intuitively observe the internal condition of the steam turbine.
4. A variety of probes: In order to better adapt to different detection needs, steam turbine industrial endoscopes are usually equipped with a variety of probes with different lengths, diameters and bending angles. The appropriate probe can be selected for detection according to the actual situation.
5. Efficient detection: The detection efficiency of the steam turbine industrial endoscope is high, and the detection can be carried out without disassembling and destroying the steam turbine, which avoids the damage to the equipment by traditional detection methods. At the same time, the image transmission technology of industrial endoscopes also improves the accuracy and reliability of detection.
When purchasing steam turbine industrial endoscopes, you need to pay attention to the following:
1. Probe length and diameter: select the appropriate probe length and diameter according to the type and part of the steam turbine to be detected. For some smaller turbine components, a smaller probe diameter such as 0Ultra-fine industrial borescopes with 8mm aperture are available in 160,000 and 300,000 pixels, while larger parts require longer probe lengths and diameters.
2. Resolution and clarity: High-resolution and high-definition endoscopes can provide clearer images and help inspectors find tiny defects and faults, such as 2 million pixel industrial endoscopes can see more details and clearer than 1 million pixel industrial endoscopes. Therefore, it is necessary to pay attention to the resolution and clarity of industrial endoscopes when purchasing.
3. Temperature range: According to the temperature requirements of the actual working environment, select the appropriate temperature range of the industrial endoscope to ensure that it can work normally under the working temperature and environmental conditions of the steam turbine.
4. Depth of field range: The internal structure of the steam turbine is complex, and the endoscope needs to have sufficient wide-angle field of view and zoom function in order to observe the entire internal situation and be able to draw out the concerns and details.
5. Pipeline material selection: choose materials with strong wear resistance and corrosion resistance, such as tungsten wear-resistant pipes.
6. Bending performance: Industrial endoscopes need to have sufficient bending performance in order to be able to adapt to different shapes of steam turbine parts and detection parts. When purchasing, you need to pay attention to the bending performance of the industrial borescope to ensure that it can meet your own inspection needs.
7. Anti-corrosion, waterproof and oil-proof performance: Some steam turbines need to be immersed in oil for testing, so it is necessary to choose an industrial endoscope with waterproof and oil-proof performance. When purchasing, you need to pay attention to the waterproof and oil-repellent performance of the endoscope and ensure that it can adapt to your own testing needs.
8. Convenience of operation: The operation of the steam turbine inspection industrial endoscope needs to be simple and easy to use, so as to improve the detection efficiency. When purchasing, you need to pay attention to the convenience of operation of industrial endoscopes and choose the products that are suitable for you.
9. Cost: The cost of steam turbine industrial endoscope is also one of the factors that need to be considered. When purchasing, you need to choose cost-effective industrial endoscopes according to your budget and needs.
10. Technical support and after-sales service: choose a reputable and good after-sales service provider, who can provide technical support, training, repair and maintenance services to ensure the normal operation and long-term use of industrial endoscopes.
11. Other matters: choose an industrial endoscope that meets the relevant safety standards and certification requirements to ensure its safety and reliability.
To sum up, it is necessary to pay attention to various factors when choosing to buy, so as to ensure that the selected steam turbine industrial borescope can meet the actual needs and play its due role.
