In order to measure the inner wall castings of the turbine volute, a large domestic hydroelectric power generation company invited our technicians to perform three-dimensional scanning inspection and analysis on the inner wall of the turbine volute of the enterprise, so as to improve the product of the inner wall of the turbine volute.

Practical problems

1. The inner wall of the turbine is welded by large castings, with a diameter of more than 10m and a height of about 4m. Traditional measuring tools cannot perform complete scanning and splicing.

2. In the process of scanning the inner wall of the turbine, the accumulated error will be too large due to the large object to be measured. How to eliminate the influence caused by the error is the biggest problem.

Holon solutions

In view of the large scanning area of the inner wall of the turbine of the enterprise, in order to eliminate the problems of cumulative scanning error and complete splicing, Hualang 3D technical engineers proposed to use in the solution: 3D scanner α7000 quickly obtains high-precision 3D data on the inner wall of the turbine + reverse design software to convert the turbine The inner wall point cloud data is converted into triangular mesh surface data.
