The main reasons for
diesel generator oil deterioration too quickly include the following:
1. Incorrect oil brand or substandard quality: Using unsuitable oil brand or substandard quality oil will cause oil deterioration. For example, generator sets with boost and rated speed greater than 2000 rpm should use CC grade or above oil.
2. Poor technical condition: The technical condition of the generator set is poor, such as blowby, oil blowby, excessive fit clearance or high oil temperature, which will cause oil deterioration.
3. Poor working environment: The generator set often operates at low temperature, low load and low speed, the piston deformation is insufficient, the combustion is incomplete, and the diesel enters the oil pan along the cylinder wall to dilute and deteriorate the oil.
4. Exhaust gas enters the oil pan: Exhaust gas enters the oil pan and condenses into water and acidic substances, causing the oil to deteriorate.
5. Oil filter problem: The oil filter is dirty or damaged, and unfiltered dirty oil enters the lubrication part, which will not only accelerate the deterioration of the oil, but also accelerate the wear of parts.
6. Improper maintenance: Failure to clean the oil tank and pipes during maintenance, or not paying attention to the grade and cleanliness of the oil when changing the oil, will cause the oil to deteriorate prematurely.
Methods to prevent oil deterioration include:
Regularly change the oil and filter element: Change the oil and filter element according to the manufacturer's recommendations, and avoid using inferior or unsuitable oil.
Maintain the normal operating temperature of the engine: Avoid running the engine for a long time at low temperature, low load, and low speed.
Regular inspection and maintenance: Regularly check the technical condition of the generator set to ensure that all components are working properly and avoid problems such as gas blowby and oil blowby.
Proper maintenance: During maintenance, ensure that the oil tank and pipes are clean to avoid contamination of the new oil.
