650MW纯凝式火电机组真空漏点查找方法及注意事项

Searching Method and Attention of Vacuum Leak of 650MW Pure Condensing Thermal Power Unit

汽轮机在运行过程中,真空值是一项非常重要的参数。真空值的高低,直接影响机组的经济性与安全性。在机组运行过程中如果出现真空值下跌问题,排出一些大的系统故障和明显的设备故障外,真空系统的泄漏是造成真空下跌的主要原因。

The value of the vacuum is a very important parameter during the operation of a steam turbine.The value of the vacuum will directly affect the economy and safety of the unit.The vacuum value directly affects the economy and safety of the unit.If there is a drop in vacuum during the operation of the unit, the main reason for the vacuum drop is the leakage of the vacuum system, except for some big system failures and obvious equipment failures.
