If thickening machine oil emulsification how to handle?

The lubrication of diesel generator set is a very important maintenance step, but many inferior lubricants in the market are mixed with too much water, affecting the actual use, how do we distinguish this inferior lubricants?

First, heat the oil in a test tube to 110 to 120 degrees Celsius. If the oil makes a “crackle” sound, it indicates water.If there is water in the oil, use indirect heating method to heat the oil to 110 to 120 degrees Celsius. When the bubbles in the oil disappear, the oil is cooled to room temperature, and the water is removed.

If unfortunately lost money to buy inferior lubricating oil complaints no door, we through the following methods to evaporate water, can continue to use.

If the oil has mild emulsion, in the following way disposal: the same brand of emulsified oil together, attend the weight for the oil weight of 1% to 3% of phenol (phenol) as emulsifier, stop stirring and heating to 50 to 80 degrees Celsius, precipitation let stand for 4 hours or longer time, after waiting for oil and water layers, removal of the lower water, can be used.

If the thickener oil is emulsified, it can be air-dried: put the emulsified thickener oil into the container with clean serpentine heating tube, stop heating with saturated steam through the serpentine tube, make the oil temperature rise to 110 to 120 degrees Celsius, at the same time into the container clean compressed air to stop stirring, so that water evaporation.Until the oil is milky white, regains its transparent color, and then cools to room temperature.
