How to remove water from lubricating oil?
If water enters into the lubricating oil, the equipment will suffer. Therefore, the earlier it is found, the better. If water is detected as early as possible and the root cause is dealt with as soon as possible, the physical and chemical properties of the lubricating oil will be prevented from being damaged. If water enters into the lubricating oil, it is necessary to remove the water in time.
Here are several common methods of lubricating oil water removal:
1.Natural settlement method:
Only free water can be removed, and lubricating oil is lighter than water. Through gravity, water can drain the water in the lower layer after the oil tank settles, but it is not suitable for emulsified water and dissolved water.
2.Centrifugal oil water separation:
It is more effective than gravity sedimentation to separate water, but it is not applicable to dissolved water and emulsified water.
3.Vacuum water removal:
When the temperature rises, the water in the lubricating oil can be evaporated by drying, but the high temperature will damage the performance of the lubricating oil. The vacuum water removal technology places the lubricating oil in a vacuum environment, and realizes the water evaporation at a temperature that does not damage the performance of the lubricating oil, which is effective for dissolved water, free water and emulsified water.
4.Use suction filter:
This kind of filter element is made of polymer Filter Material, which can absorb water, then form colloid, and remove free water and emulsified water.
Water content is one of the important reasons for the failure of lubricating oil and the mechanical corrosion and wear. The countermeasures are mainly prevention. Monitoring the water content can avoid the damage of the equipment. Strictly speaking, there is no warning value for the water content, but the lower the water content is, the better. Use waterproof and moisture-proof accessories such as dry respirator, use efficient seal, etc., remove the water in time after finding the water, and use centrifugal type. Oil water separator and vacuum water removal equipment are very necessary for prolonging the service life of lubricating oil and equipment.
