3油循环步骤OilCirculatingSteps
1)油箱上油TankOilSupply
油箱上油前,在确认油箱放油阀关闭正确,并采取了一定的防范措施,即可向油箱缓慢上油,上油时检查各管道连接处是否漏油,如有漏油修复后再继续上油,油箱距离油箱顶部约100mm时,停止上油,润滑油牌号ISOVG46汽轮机油,注油量约9m3。
注油时用滤油机或经过滤网注入,禁止直接倒灌。
灌油或放油时,储存汽轮机油的容器应清洁,不得使用盛过其它油品而未作彻底清理的容器,装油和运油时要防止与其它油品容器混淆。

2)第一阶段油冲洗:
润滑油管路
Firstphaseofoilflushing:
oilpipes
流程为:
主油箱→辅助油泵(交、直流事故油泵可同时投入运行)→双联冷油器→双联滤油器(润滑油)→润滑油进油母管→各轴承处进油支管→各轴承处进回油管路临时短接→各轴承处回油支管→回油母管→主油箱
Process:
maintank→auxiliarypumps(ACandDCemergencypumpscanoperateatthesametime)→double-connectionoilcooler→double-connectionfilter(oil)→mainoilinletpipe→oilinletmanifoldsatbearings→temporaryshorttubesforoilsupplyandreturnatbearings→oilreturnmanifoldsatbearings→mainoilreturnpipe→mainoiltank
启动辅助润滑油泵(交、直流事故油泵可同时投入运行),同时用透明夹丝软管将压榨式滤油机串联在主油箱上在线滤油,冲洗24小时,冲洗油压尽可能接近系统工作压力;冲洗油温,应使油温冷、热交替变化,以8小时为1个循环周期,期间低温约25℃,高温约75℃。

停辅助润滑油泵和交、直流事故油泵,用压差式滤油机将主油箱的油倒入已清理干净的储备油箱,然后把油箱和润滑油滤网清理干净。
这样进行反复冲洗,直到油质合格。
