Abstract
After the centrifugal compressor balance disc is installed in the final stage impeller, the rotor system can be protected because the axial force of the rotor is offset by the axial thrust generated by the pressure difference between the two sides. The balance plate plays an important role in the safe operation of the centrifugal compressor rotor system, and its strength is the guarantee for the safe operation of the centrifugal compressor. In order to analyze the reliability of the balance disc, this paper uses the static finite element method to analyze its strength. Considering the influence of centrifugal force, the stress and strain distribution of the balance plate under different rotating speeds are obtained, which plays a certain reference role for the design of the balance plate. The stress and strain distribution of the balance disc under the single action of centrifugal force is studied, and the influence of rotating speed on the strength of the balance disc is obtained.
