干熄焦汽轮机润滑油发生严重乳化现象的探讨

Discussion on the Serious Emulsification of Coke Dry Quenching Turbine Lubricating Oil

1#干熄焦汽轮机组投运一年后,出现了润滑油水分超标,指标从0%增长至4.4%(标准为0.2%以下),最终造成油乳化现象,给汽机运行带来油膜形成不好、油压偏低、轴承振动大及调节系统卡阻等危害,文章对该问题进行分析并提出有效措施。

The lubricating oil＇s moisture content of the 1 # CDQ turbine exceeded the standard just one year after the operation. The moisture content in lubricating oil increased from 0% to 4.4% （ The standard is below 0.2% ）. The oil emulsified at last. This phenomenon brought great harm to turbine, such as the oil - film formation is not good,low oil pressure, large bearing vibration, adjusting system obstacle. This article analyzes these above - mentioned problems and proposes effective measures.
