本文分析对中压蒸汽管道温度计套管断裂原因,对温度计套管在吹扫阶段、工作过程的振动频率进行了计算,认为该温度计套管的结构参数存在问题;温度计套管改进后,对振动频率重新计算,满足要求。
In this paper, the causes of the casing tube breakage of the medium pressure steam pipe thermometer are analyzed. The vibration frequency of the casing of the thermometer casing during the purging phase and the working process is calculated. The structural parameters of the casing of the thermometer are considered to be faulty. Frequency recalculation to meet the requirements.
