Steam turbine is the main equipment of modern thermal power plant. It is a rotary steam power device used in metallurgical industry, chemical industry and ship power plant. The rotor equipped with blade row rotates. The customer needs to scan the rotating blade row of the steam turbine to obtain data for comparison and analysis. Our company's new scanning equipment is used to comprehensively scan the sample to obtain the required data and apply it to the work of the steam turbine to create better equipment.

        The steam turbine has a large volume and appearance, a small gap between the blade rows, and is easy to form an angle. The customer requires high accuracy of scanning data, good scanning technology, and the ability to complete the work in a short time, which is very challenging.

         The traditional scanning method has limitations in use. The sample is too large, difficult to splice, and consumes too much time. It cannot meet the needs and solve the problem quickly.

        Regardless of the size of the sample, we have equipment suitable for scanning. For this time, the customer wanted to scan the steam turbine. Our engineers used the 3D photogrammetry system HL-3DP to conduct a comprehensive scan. First, they attached the coding points, and then took images from different angles. , import the image into the HOLON3DP software for processing, and the software will automatically combine the images to obtain the 3D coordinates of the encoding point.

        The obtained 3D data is then imported into the 3D software for comparison and analysis with the original data, and a detection data analysis report is generated. The detailed scan is very good, the data is complete, and the problem can be directly seen. The customer is very satisfied with the data we scanned and can actually solve it. To solve the problem, the steam turbine design can be improved based on the test data to produce more market competitive products.
