摘要
以常用的温度计保护套管为例,计算其固有频率,并计算共振时的最大流速和压力。通过典型的温度计套管频率的计算,推导出哪些工况条件下要特别注意对温度计保护套管频率进行计算,避免产生共振,导致生产事故,并提出温度计保护套管在设计选型时的注意事项。
Natural frequency and its maximum flow speed and pressures are calculated withcommon thermowell as case. Under which working condition needs frequency calculationparticularly is elicited through typical one calculation. According to calculation, the resonancecan be avoided to result in production accident.thermowell are put forward.The attentions on design and type selection of
