Moisture content Water can exist in oil in three states or phases . Dissolve Water emulsified water Free Water Dissolve Water :- Dissolved water, is characterized by individual water molecules dispersed throughout the oil. Dissolved water in a lubricating oil is comparable to moisture in the air on a humid day - we know the water is there , but because it is dispersed molecule-by-molecule, it is too small to see. emulsified water . :- Once the amount of water has exceeded the maximum level for it to remain dissolved, the oil is saturated. At this point, the water is suspended in the oil in microscopic droplets known as an emulsion . Free Water :- free water accumulates at the bottom of the lube system. IMPACT OF WATER CONTAMINATION ON LUBRICANTS • The presence of water in a lubricating oil can cause the progress of oxidation to increase tenfold, resulting in premature aging of the oil, particularly in the presence of catalytic metals such as copper, lead and...
