Diesel generators generally need to change the oil once after 500 hours of operation. Sometimes the oil becomes thinner and impurities increase before the replacement period is reached, or the oil becomes thinner and impurities increase before it is used, making it thinner. impossible to continue using it. Reasons why diesel generator oil deteriorates too quickly:
1. The oil quality is incorrect and the quality does not meet the requirements. Generally, quiet diesel generators with boosted and calibrated speeds above 2,000 rpm should use engine oil above CC grade.
2. The technical condition of the diesel generator set is not good, with gas and oil leakage, the mounting gap is too large or the oil temperature is too high.
3. Diesel generators often operate atlow temperatures, low loads and low speeds. Piston deformation is insufficient and combustion is incomplete in the oil pan along the cylinder wall. the oil becomes diluted and deteriorates.
4. Exhaust gases enter the oil pan and condense into moisture and acidic substances, causing engine oil to deteriorate.
5. The oil filter element is dirty. Unfiltered dirty oil enters the lubricating parts and accelerates the wear of diesel generator set parts.
6. The filter element sealing ring is broken and internal leakage occurs. Some of the engine oil passes directly through the filter without the filter element, causing engine oil to deteriorate. The thinning of the engine oil and the increase in impurities will prevent the engine oil from performing its normal function and will accelerate the wear of the various components of the power unit.diesel ectrogen.
If it turns out that the engine oil has deteriorated before the replacement period, it is necessary to find out the cause in time, repair it and replace the engine oil to ensure normal operation of the unit.
