在火力发电站安装建设中,仪表检测介质的泄露是个令人头痛的问题。一般情况下,仪表介质泄露量都不大,但却影响仪表测量的准确性或控制性能,给机组试运行留下重大的安全隐患。本文从以下几个方面着手以期用简单直接的方法降低仪表安装的漏点:严格按照图纸设计用材、选用合适的连接件、参与系统管路的试水压试验、加强对设备的验收检查和厂家资料的审图工作、提高施工人员的安装技术。
Installation of thermal power station construction, instrumentation leak detection media is a headache. Under normal circumstances, the amount of leakage of the instrument medium is not large, but it affects the accuracy of measurement or control performance instrumentation, leaving a significant safety hazard trial operation of the unit. This article from the following aspects in order to reduce the leakage of instrumentation installation with a simple and direct method: in strict accordance with the design of the drawing materials, the use of suitable connectors, test hydrostatic pressure in the system piping to strengthen the acceptance inspection equipment and manufacturers Data review plans to improve the construction of the installation of technology.
