摘要
本文分析并推测了温度计套管弯曲甚至断裂的可能原因——共振,阐述了共振产生的原因,总结出了一个温度计套管性能测试的方法步骤,并通过一个实例详细阐述了温度计套管固有频率和漩涡脱落频率之间的关系,以及温度计套管的应力需要满足的条件。
The article analyses and speculated that the thermometer casing possible causes of bent and even broken resonance, resonance causes are described. Summarizes a thermowell performance test methods and steps, and an example to elaborate the thermowells for natural frequencies and the relationship between Vortex shedding frequency, and stresses the need to meet the conditions of the thermowell.
