Jul. 10, 2021

Engine oil is the blood of diesel generator set. It is an essential part to ensure the normal operation of diesel generator set. The engine oil of diesel generator set plays the role of lubrication, cooling, sealing and cleaning. Users should pay attention to whether the engine oil deteriorates when using diesel generator set. If the engine oil deteriorates, it needs to be replaced immediately. So how can the user judge whether the engine oil of diesel generator set is deteriorated? Generator manufacturers - Dingbo power share several methods for you, let's get to know.


1. Lighting methods.

On a sunny day, use a screwdriver to make a 45 degree angle between the lubricant and the horizontal plane. Watch the oil drop in the sun. Under the light, it can be clearly seen that there is no wear debris in the lubricating oil. If there are too many wear debris, the lubricant should be replaced.


2. Oil drop tracking method.


Take a piece of clean white filter paper and drop a few drops of oil on it. After oil leakage, a good lubricant is powder free, dry and smooth by hand, with yellow spots. If there is black powder on the surface and it can be felt by hand, it means that there are many impurities in the lubricating oil, so the lubricating oil should be replaced.


3. Hand twisting.

Grind the oil repeatedly between thumb and index finger. Good lubricating oil feel is lubricated, less wear debris, no friction. If you feel a lot of friction between your fingers, it indicates that there are many impurities in the lubricating oil. This kind of oil can not be reused, so you should replace it with a new one.


4. Oil flow observation method.


Take two measuring cups, one of which is filled with the lubricating oil to be inspected, and the other is placed on the table. Then lift the measuring cup filled with lubricating oil from the table for 30-40 cm, and tilt it so that the lubricating oil flows slowly to the empty cup. Observe the flow rate. The high-quality lubricating oil flow should be slender, uniform and continuous. If the oil flow is fast and slow, sometimes the flow is large, it means that the lubricating oil has deteriorated.
