1000MW二次再热机组汽动给水泵泵轴抱死原因分析及预防

Analysis and prevention of pump axle suspension of secondary reheat supercritical unit steam feed pump

在1000 MW超超临界机组投产整组启动过程中,汽动给水泵泵轴抱死直接危害机组的安全稳定经济运行。本文就二次再热超超临界机组汽动给水泵泵轴抱死的原因进行分析并提出预防措施。

During the start - up of the whole set of 1000 MW supercritical unit, the shaft holding of the steam feed water pump directly endangers the safe and stable economic operation of the unit. In this paper, the causes of shaft lock of the steam feed pump in the secondary reheat supercritical unit are analyzed and the preventive measures are put forward.
