Centrifugal compressor is an indispensable key equipment in the industrial field, and its performance directly affects the economy and efficiency of industrial production. In this paper, we study the structure design of centrifugal compressor and predict and optimize its performance. Firstly, this paper expounds the structure and working principle of the centrifugal compressor and analyzes the design points of its key components. Then, using the methods of flow field analysis and thermodynamic analysis, the mathematical model of the centrifugal compressor is established, and its performance is predicted. Based on this, the structure of the centrifugal compressor has improve its efficiency and reliability. Moreover, the control strategy and dynamic characteristics of the centrifugal compressor are studied, which provide theoretical support for its stable operation and optimized control in practical applications. The research results of this paper not only provide new ideas and methods for the design of centrifugal compressor, but also provide strong support for energy saving and emission reduction and efficient production in the industrial field.
