Generally, the engine oil of the diesel 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.

柴油發(fā)電機(jī)組機(jī)油為何會(huì)變質(zhì)過(guò)快

Why the engine oil of diesel generator set deteriorates too quickly

①、機(jī)油牌號(hào)不對(duì)、質(zhì)量達(dá)不到要求，一般增壓和標(biāo)定轉(zhuǎn)速大于2000r/min的柴油發(fā)電機(jī)應(yīng)選用CC級(jí)以上的機(jī)油；

① The engine oil grade is incorrect and the quality cannot meet the requirements. Generally, the diesel generator with supercharging and rated speed greater than 2000r/min should use the engine oil above CC level;

②、柴油機(jī)發(fā)電機(jī)技術(shù)狀況不好，竄氣、竄油、配合間隙過(guò)大或油溫過(guò)高；

② The diesel generator is in poor technical condition, with gas and oil leakage, too large fitting clearance or too high oil temperature;

③、柴油機(jī)發(fā)電機(jī)經(jīng)常在低溫、低負(fù)荷、低速下運(yùn)轉(zhuǎn)，活塞變形量不夠，燃燒不完全，有柴油沿缸壁進(jìn)入油底殼使機(jī)油稀釋變質(zhì)；

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

④、廢氣進(jìn)入油底殼凝結(jié)成水分和酸性物質(zhì)，使機(jī)油變質(zhì)；

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

⑤、機(jī)油濾芯臟，未經(jīng)濾清的臟機(jī)油進(jìn)入潤(rùn)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(fā)生內(nèi)漏，一部分機(jī)油未經(jīng)濾芯而直接通過(guò)濾清器而造成機(jī)油變質(zhì)。

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

柴油發(fā)電機(jī)組一般運(yùn)行500h后應(yīng)更換機(jī)油一次，但有時(shí)候未到更換期，或還沒(méi)用多長(zhǎng)時(shí)間就出現(xiàn)機(jī)油變稀、雜質(zhì)增多現(xiàn)象，無(wú)法繼續(xù)使用。

Why the engine oil of diesel generator set deteriorates too fast: the engine oil is of wrong brand and quality cannot meet the requirements. Generally, the diesel generator with supercharging and rated speed greater than 2000r/min should use the engine oil above CC level; The diesel generator is in poor technical condition, with gas and oil leakage, too large fitting clearance or too high oil temperature; The diesel engine generator often operates at low temperature, low load and low speed, the piston deformation is not enough, the combustion is incomplete, and diesel enters the oil pan along the cylinder wall to dilute and deteriorate the oil; The waste gas enters the oil pan and condenses into water and acid substances, which will deteriorate the engine oil; The oil filter element is dirty, and the unfiltered dirty oil enters the lubricating part, which accelerates the wear of parts.
