How to distinguish between genuine and fake diesel generator oil
The oil lubrication of diesel generator sets is very important to the maintenance process, but many inferior oils on the market are mixed with too much moisture, which affects actual use. How to distinguish inferior lubricants? First, the oil in the hot test tube reaches 110 to 120 degrees Celsius, such as "Cracking" oil sound, indicating that there is water in the oil. If there is water in the oil, heat the oil to 110 ° C to 120 ° C by indirect heating. When the air bubbles in the oil disappear and cool to normal temperature, the water is removed.
If we unfortunately complain about buying inferior lubricants, we can use the following method to evaporate water.
If the oil has a mild emulsion, use the following method: emulsify the same brand of oil, increase the weight of the oil by 1% and the weight of 3% by weight of phenol (phenol) as an emulsifier. Stop stirring and heat to 50 ° C to 80 ° C. Precipitation gives way 4 hours or more, after waiting for the oil and water layer, the downstream water is removed and can be used.
If the emulsified mechanism of thickened oil can be treated by air drying method: In the container of emulsified heavy oil mechanism and a clean serpentine heating tube, heating is stopped by saturated steam through a coil, and the temperature of the oil rises to 110 to 120 degrees Celsius, and the container is Clean the air and stop stirring, the water will evaporate. Until the milky oil fades, the restorer is transparent, then cools down to normal temperature and is usable.
The above is a brief introduction on how to distinguish the true and false of diesel generator oil. I hope this knowledge will help you!
