The industrial endoscope plays a vital role in boiler inspection. Its high precision and flexibility make it an ideal tool for inspecting the internal structure and quality of the boiler. The following are the specific steps and precautions for industrial endoscope inspection of boilers:
Choose a suitable endoscope: According to the specific structure and inspection requirements of the boiler, select the appropriate endoscope model and probe. The endoscope should have high resolution, good lighting and rotation functions so that the situation inside the boiler can be clearly observed.
Prepare the inspection environment: Make sure the boiler is in a safe state, turn off all relevant power supplies and valves, and remove debris and dirt inside the boiler for better observation.
Determine the inspection area: According to the design drawings and inspection requirements of the boiler, determine the areas and key parts that need to be inspected, such as boiler headers, pipes, water-cooled walls, superheaters, reheaters, etc.
Enter the inspection area: Send the probe of the endoscope into the boiler through the boiler's hand hole, pipe joint or other suitable entrance. Ensure that the probe can smoothly enter and reach the area that needs to be inspected.
Observation and recording:
Observe the internal situation of the boiler through the display screen of the endoscope, and pay attention to check whether there are defects such as corrosion, cracks, blockages, foreign matter, etc.
Record and describe the observed defects in detail, including the location, size, shape and severity of the defects.
If necessary, the measurement function of the endoscope can be used to quantitatively measure the defects so as to more accurately evaluate their impact.
Comprehensive analysis: Based on the observed defects and recorded data, make a comprehensive assessment of the internal structure and quality of the boiler. Analyze the causes and possible impacts of the defects, and propose corresponding repair or improvement measures.
Safety first: During the inspection process, the safety operating procedures should be strictly followed to ensure the safety of personnel and equipment. Avoid testing in dangerous conditions such as high temperature, high pressure or toxic gases inside the boiler.
Choose a suitable probe: According to the structure and size of the boiler, choose the appropriate probe size and shape. Ensure that the probe can smoothly enter and cover all areas that need to be inspected.
Keep clean: During the inspection process, the probe and lens of the endoscope should be cleaned regularly to avoid the influence of dirt and impurities on the observation results.
Accurate records: Accurately and in detail record the observed defects and data for subsequent analysis and evaluation.
In power plant boilers, industrial endoscopes are widely used in various inspection scenarios. For example, in the inspection of boiler headers, technicians can observe corrosion, cracking, and foreign matter inside the headers through endoscopes. At the same time, endoscopes can also be used to detect corrosion and cracking of the inner wall of boiler pipes, as well as corrosion and cracking of the inside and blades of turbines. These test results provide an important basis for the maintenance and repair of boilers.
In summary, industrial endoscopes have broad application prospects and important value in boiler inspections. Through the reasonable selection and use of endoscopes, a comprehensive and accurate evaluation of the internal structure and quality of the boiler can be achieved, providing a strong guarantee for the safe operation and long-term use of the boiler.
