摘要
某电厂锅炉送风机，多次发生叶片断裂事故，严重影响了电厂生产的正常运行。本文针对风机转子进行了固有频率振型和临界转速计算。根据对计算结果的对比分析，排除了转子结构不合理是造成事故直接原因的假设，避免了电厂对转子结构进行不必要的改造。
The forced draft fans of a certain power station suffered repeated failures because of blade ruptures, seriously disrupting the normal operation of the power station. Calculations were conducted of the fan rotor natural frequency, vibration modes and critical speeds. On the basis of a contrast analysis of the calculation results, the assumption that an irrational rotor construction caused the failure has been ruled out. This made it possible to avoid the unnecessary work relating to the modification of the fan rotor structure.
