How to judge whether the oil of diesel generator set has reached the time for replacement?
2021-10-20
After the diesel generator set is used for a period of time, the engine oil needs to be replaced. When can the engine oil of the diesel generator set be replaced? For some friends who are not familiar with the use of diesel generator sets, sometimes it is difficult to identify.
First of all, we should understand that the engine oil used by different manufacturers and diesel generator sets with different power is different. Generally, the new engine works 50 hours after the first operation and 50 hours after medium repair or overhaul. The oil change cycle is generally carried out at the same time as the oil filter (filter element). Generally, the oil change cycle is 250 hours or one month. With class 2 engine oil, the engine oil can be changed only after 400 hours of operation, but the engine oil filter (filter element) must be replaced.
If you want to determine the replacement time of diesel generator set exactly, you must understand some of the determination methods:
1. Use two glass test tubes with a diameter of 0.5cm and a length of 20cm to load 19cm of new engine oil and used engine oil respectively. After sealing, the two tubes are inverted at the same time and record the rising time of bubbles. If the difference between the two exceeds 20%, it indicates that the viscosity of used engine oil has decreased too much and should be replaced.
2. Compare the new oil and the used oil on the white filter paper. If there are more black spots in the used oil drops, it indicates that the oil has not deteriorated and should not be replaced; If the engine oil is dark brown, it is deteriorated and should be replaced.
The replacement of diesel generator oil can well ensure the stable use of the generator set, which also effectively prolongs the service life of the diesel generator set to a certain extent. Therefore, the replacement time of the diesel generator set must be determined accurately in the process of using the diesel generator set.
