The condensate pump often causes structural resonance after conversion transformation, which affects the safe and economic operation of the unit. In order to solve the problem of structural resonance of the condensate pump, this paper analyzes the mechanism of structural resonance, fault characteristics and the frequency range of the exciting force of the main fault of the condensate pump, and puts forward the necessary conditions for stimulating structural resonance. According to the above analysis, four measures are obtained. And combined with the practical application to discuss the advantages and disadvantages. Finally, the corresponding treatment measures are comprehensively applied to practical cases, and the problem of structural resonance is effectively solved. The research results and treatment experience can provide reference for the treatment of structural resonance of condensate pump in large thermal power units.
