U型管换热器振动的分析计算及处理对策

Analysis and Calculation of Vibration of U-Tube Heat Exchanger and Its Countermeasures

通过对实际运行中发生振动的U型管换热器进行振动检测、并对管束振动进行计算及分析 ,判断管束因壳侧气体流经管束及折流板时 ,气流及声波所产生的振动诱发管束产生了共振 ,通过在折流板间加装纵向支撑板 。

Through measuring the vibration of U-tube heat exchangers in operation and analyzing the vibration of tube bundles, it can be judged the resonance of tube bundles which induced by gas streams and sound waves, is produced while gas flows through shell side and baffle plates. By adding longitudinal support plates between baffle plats, the vibration of heat exchanger can be effectively eliminated.
