摘要
针对大连某热电厂300 MW供热机组汽轮机升速过程中润滑油系统出现的异常问题,阐述了润滑油系统的结构和工作原理,分析了直流油泵异常启动情况和联启条件,通过润滑油供油系统试验得到了直流润滑油泵联启异常的原因,提出了相应的处理方法,解决了300 MW供热机组直流润滑油泵联启异常的问题,保证了机组的安全稳定运行。
Aiming at the abnormality of lubricating oil system during raising the steam turbine speed of the 300 MW heat supply unit in a Dalian thermal power plant, this paper introduces the structure and working principle of lubri- cating oil system, analyzes abnormal start - up and conditions for joint start - up, discovers the reasons for abnor- mality through the experiment on the lubricating oil supply system, and proposes measures to solve the abnormal start - up of the dc lubricating oil pump of 300 MW heat supply unit and to guarantee the safe and stable operation.
