[Abstract]:As an important power production equipment, air compressor is widely used in various aspects of daily production, such as mining, metallurgy, mechanical manufacturing, electronic power, chemical industry, textile, packaging industry and so on. The analysis and research of rotor vibration fault of centrifugal compressor is of great significance to improve the production efficiency and economic benefit to ensure the safe and reliable operation of the centrifugal compressor. Aiming at the operation vibration of DA410-61 centrifugal compressor designed and manufactured by Shanghai Blower Factory, the structure and frequency of the rotor set of the compressor are analyzed in this paper. The main contents are as follows: first of all, In this paper, the vibration failure phenomenon and its causes in the operation of the rotor group of the centrifugal compressor are analyzed. Secondly, the three-dimensional model of rotor group is established by SoildWorks, and the finite element optimization analysis of rotor group is carried out by Simulation. Thirdly, from the results of finite element analysis, the natural frequency and critical speed of the rotor group are obtained, and the corresponding measures to improve the structure of the rotor group are put forward. The analysis of Simulation software shows that the retrofit scheme is feasible and the compressor unit runs smoothly after the revamping.
