WebSep 2, 2024 · Foam and air entrainment problems are quite common in lubricating oil circulation systems. Problems that may arise as a result of foaming include fluctuations in oil pressure, oil pump cavitation, loss of oil through breathers and dipsticks and decrease in lubrication and cooling efficiencies. The presence of air bubbles in the fluid can also ... WebBecause foam suppression in a lubricating oil is closely related to the air/oil surface tension, any contamination that can result in either an increase in air entrainment, such as solid particles, or a decrease in surface tension can cause this type of effect.
WebThe test reports three values: the amount of foam at the end of the 5-minute blowing period (foaming tendency), the amount of foam at the end of the settling time (foam stability), and the settling time. Most new lubricants have a foaming tendency ranging from 10-60 milliliters and a foam stability of 0 milliliters.
