Technical scheme for improving the development accuracy of heavy-duty gas turbine compressor cylinder

In view of the current development problems of the introduced heavy-duty gas turbine compressor cylinder, such as poor positioning effect of the positioning structure of the surface flange, large processing deformation, unstable processing accuracy, and difficulty in ensuring assembly accuracy, the optimization of the positioning structure of the surface flange and the improvement of the manufacturing process were proposed to improve the design quality and ensure the manufacturing accuracy.
