Research and Application of Key Technology of Deformation Control of HP Cylinder of Nuclear Power Turbine
This paper takes the high-pressure cylinder of a large nuclear power turbine as the research object,establishes its three-dimensional model,and uses ANSYS/WORKBENCH to calculate and analyze the influence of temperature distribution at the cylinder shaft seal and bolt preload on cylinder deformation during steady-state operation.At the same time,a treatment plan to control cylinder deformation is proposed specifically.Good results have been obtained.
