发电机组一般运行500h后应更换机油一次，但有时候未到更换期，或还没用多长时间就出现机油变稀杂质增多现象，无法继续使用。那么发电机组机油为何会变质过快？下面焦化发电机组厂家为您解说。

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机油牌号不对质量达不到要求，一般增压和标定转速大于2000r/min的发电机应选用CC级以上的机油；

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机发电机技术状况不好，窜气窜油配合间隙过大或油温过高；

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机发电机经常在低温低负荷低速下运转，活塞变形量不够，燃烧不完全，有沿缸壁进入油底壳使机油稀释变质；

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废气进入油底壳凝结成水分和酸性物质，使机油变质；

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

⑤机油滤芯脏，未经滤清的脏机油进入润滑部位，加速了零件的磨损。

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

⑥滤芯密封圈破裂而发生内漏，一部分机油未经滤芯而直接通过滤清器而造成机油变质。

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.
