[0002] Lubricating oil comes into contact with mixed air during use, generating bubbles in the oil. Some of the bubbles are retained inside the oil, while the other part rises and floats on the surface of the oil to form foam. The time it takes for the bubbles to rise from the oil to the oil surface is called air release. The agitation of the air in the lubricating oil and equipment (such as bearings, couplings, gears, pumps and return oil pipes) may cause dispersion of tiny bubbles in the oil. If the residence time in the reservoir is too short, the bubbles cannot rise to the oil surface, and the mixture of air and oil will circulate in the lubricating oil system.
