摘要
在汽轮机调速系统中,主蒸汽阀门是整个汽轮发电机系统的重要组成部分,在系统中起到“关断”的作用,是机组的关键部件,保障机组的安全启停和运行。在分析汽轮机主蒸汽阀门2种经典缺陷处理方式的基础上,对主蒸汽阀门的检修工艺进行了探讨,提出了汽轮机主蒸汽阀门的检修建议及检验措施。
In the steam turbine governing system,the main steam valve is an important part of the whole steam turbine generator system,which plays the role of"off"in the system and is the key component of the unit to ensure the safe start-stop and operation of the unit.Based on an analysis of two kinds of classical defect treatment methods of the main steam valve of steam turbines,the maintenance technology of the main steam valve of steam turbine is discussed,and maintenance suggestions and inspection measures of the main steam valve of steam turbines are put forward.
