How to improve the quality of fan flanges

In the production of wind turbine flanges, improving quality requires starting from five core links: material selection, structural optimization, manufacturing process, quality control, installation, and maintenance. Based on the characteristics of local wind power projects and industry technical standards, a systematic improvement plan should be developed. The following are specific measures and analysis:

1、 Material selection: Improve basic performance

Using high elastic modulus materials

Optimize material processing technology

Heat treatment: Eliminating internal stress and improving material uniformity through quenching and tempering processes.

Surface treatment: Sandblasting or galvanizing treatment is used to enhance anti-corrosion ability and extend the service life of flanges.

2、 Structural optimization: Enhance deformation resistance capability

Increase flange thickness and outer diameter

Improve the design of the sealing surface

3、 Manufacturing process: Improve machining accuracy

Precision forging and ring rolling technology

Numerical Control Machining and Testing

4、 Quality control: strict testing and traceability

Whole process quality inspection
