發電機組一般運行500h后應更換機油一次，但有時候未到更換期，或還沒用多長時間就出現機油變稀雜質增多現象，無法繼續使用。那么發電機組機油為何會變質過快？下面焦化發電機組廠家為您解說。

Generally, the engine oil of the generator set should be replaced once after 500h of operation, but sometimes the replacement period is not reached, or the engine oil has become thinner and impurities have increased within a short period of time, which makes it impossible to continue to use. Then why does the engine oil of the generator set deteriorate too quickly? The coking generator set manufacturer will explain it to you.

①機油牌號不對質量達不到要求，一般增壓和標定轉速大于2000r/min的發電機應選用CC級以上的機油；

① The engine oil grade is incorrect and the quality cannot meet the requirements. Generally, the engine oil of CC grade or above shall be used for the generator with supercharging and rated speed greater than 2000r/min;

②機發電機技術狀況不好，竄氣竄油配合間隙過大或油溫過高；

② The technical condition of the generator is not good, the air and oil leakage clearance is too large or the oil temperature is too high;

③機發電機經常在低溫低負荷低速下運轉，活塞變形量不夠，燃燒不完全，有沿缸壁進入油底殼使機油稀釋變質；

③ The generator often operates at low temperature, low load and low speed, the piston deformation is not enough, the combustion is incomplete, and the oil enters the oil pan along the cylinder wall to dilute and deteriorate the oil;

④廢氣進入油底殼凝結成水分和酸性物質，使機油變質；

④ The waste gas enters the oil pan and condenses into water and acid substances, which will deteriorate the engine oil;

⑤機油濾芯臟，未經濾清的臟機油進入潤滑部位，加速了零件的磨損。

⑤ The oil filter element is dirty, and the unfiltered dirty oil enters the lubricating part, which accelerates the wear of parts.

⑥濾芯密封圈破裂而發生內漏，一部分機油未經濾芯而直接通過濾清器而造成機油變質。

⑥ The sealing ring of the filter element is broken and internal leakage occurs. Some oil passes through the filter element without passing through the filter element, causing oil deterioration.
