| Abstract: | The centrifugal blower of RPF system applied in PTA is taken as an example, strength and distortion of welding volute is studied in this paper. FEM is used to analyze welded volute of centrifugal blower, then the distribution of stress and distortion of the force and load is obtained. The axial distortion of mechanical seal connection flange is analyzed in detail. It has provided reliable theoretical basis for improving design. |
