弹性元件式压力表的故障分析及维修

摘要

Elastic element pressure gauge is a kind of measuring instrument applied on boiler and pressure vessels,the faults of pressure gauge are mainly founded to be the skipping and sticking of the pointer,the stability of the indicating value,displacement of the pointer,the turbulence of the hairspring and otherwise,relevant repair measures shall be taken according to specific causes,so as to ensure the accuracy of the measurement of pressure gauge,what shall be keep in mind is that,retest shall be carried out after inspecting,adjusting and repair.%弹性元件式压力表是用于锅炉、压力容器等方面的计量器具. 压力表所出现的故障主要为指针有跳针或滞针现象、示值不稳定、指针位移及表芯游丝紊乱等,应据具体故障原因采取相应的维修措施,以保证压力表计量的准确性. 值得注意是,检测及调修后应进行复查.
