135MW汽轮机润滑油压突降问题分析与处理

Problems Analysis and Treatment on 135MW Turbine Lubricating Oil Pressure Dump

对某国外项目135MW汽轮机试运行期间2次润滑油压突降原因进行详细分析,经过逐一排查最终排除了故障,并给出了汽轮机在安装阶段预防润滑油系统故障的建议,对同类型机组具有一定的借鉴意义。

This paper will analyses the cause of the lubricating oil pressure two-time dump during the commissioning period of a 135 MW steam turbine in detail, finally remove the fault after searching one by one, and give the suggestions during the turbine installation phase which could prevent lubricating oil system fault. This paper is certain reference of the same type steam turbine.
