The regular renewal of oil can ensure the stable running ofdiesel generator set.This maintenance can prolong the service life of diesel generator set effectively, so it is very import to the confirm the oil replacing interval during use diesel generator set.
Usually, the oil needs to be changed after diesel generator set run for a period. How about the oil changing interval of the diesel generator set? Sometimes it is very difficult for a new user to determine when we need change the oil. There are two method to identify when we need change the oil as bellowing:
1. Compare the new oil with the used oil by drop them on the white filter paper at the same time. If there are many black spots in the used oil, the oil has not deteriorated, so no need replace it, if the oil is dark brown, it is deteriorated, you need replace the oil.
The regular renewal of oil can ensure the stable running ofdiesel generator set.To some extent, it can prolong the service life of diesel generator set effectively, so it is needed to confirm the oil replacing interval during use diesel generator set.
2. Select two glass tube (diameter is 0.5cm, length is 20cm ),fill new oil and used oil into the glass tube respectively,each liquid height need reach 19cm, turn this two glass tubes upside down at the same time after sealed. Record the time of bubble rise, if the difference between this two tubes is more than 20%, it means that the used oil viscosity decreased too much, the user need replace the oil.
We need to know that different diesel generator sets and different power of diesel generator sets with different oil renewal interval. In general, for new engine, the oil of generator need to be replaced after running 50 hours at the first time , or 50 running hours after medium maintenance and overhaul.Usually the oil replacement cycle keep the same as the oil filter (filter element). The normal oil renewal interval is 250 hours or one month.Use type 2 oil, the oil renewal interval can be extended to 400 hours, but the oil filter (filter element) must be replaced after the generator running for 250 hours or one month.
