【正文】 汽輪機潤滑油系統(tǒng)概述 汽輪機油系統(tǒng) 在汽輪機中主要 擔任著潤滑、冷卻、控制和密封 的 作用 。 Preliminary estimates the economic costs required for this cleaning process. Key words： The lubricating oil system。 Discussed the technological conditions of the whole process of cleaning。本方案提出了汽輪機油系統(tǒng)清洗的工藝流程；討論了 整個 清洗過 程的 工藝條件； 分析了整個流程的物料衡算和熱量恒算 ；初步估算了 本 清洗工藝所需的經(jīng)濟成本。 若潤滑油系統(tǒng)在運行年限很長而且未經(jīng)過化學清洗，則很難達到規(guī)定的清潔度要求，就會存在油泥、腐蝕產(chǎn)物以及其他顆粒狀物質(zhì)。 燃煤電廠 300MW 機組潤滑油系統(tǒng)清洗初步方案 目錄 1 緒論
