汽轮机排汽装置低真空测点取样可靠性研究

Reliability Research for Turbine Exhaust Equipment’s Vacuum Measurement Sampling

汽轮机排汽装置真空度的测量,是空冷发电机组安全和经济运行的重要参数,根据空冷汽轮机低真空测点,取样设计及安装资料、运行数据、检修记录等数据,从取样的独立性、取样管路的敷设与安装、取样装置的可靠性,三方面进行深入分析,研究并提出汽轮机低真空测点取样可靠性的改进方案.

The vacuum measurement of steam turbine exhaust device is an important parameter for the safe and economic operation of air-cooled generating units. Based on the low vacuum measurement points, sampling design and installation data, operation data and maintenance records of air-cooled steam turbines in Shanxi Datang International Linfen Thermal Power Co., Ltd., this paper studies and puts forward the low vacuum of steam turbines. Suggestions on improving the reliability of sampling points.
