Water In Oil Contamination - machinerylubrication.c

The Effects of Water Contamination. In a lubricating system, the two most harmful phases are free and emulsified water. In journal bearings for example, the incompressibility of water relative to oil can result in a loss of the hydrodynamic oil film that in turn leads to excessive wear. As little as one percent water in oil can reduce the life expectancy of a journal bearing by as much as 90 ...

WATER CONTAMINATION IN O

Water is widely considered as the second most destructive contamination to a lube system, after particulate contamination. This article will focus on how water exists in oil, the effects of water on oil and lube systems and measurement of water amount in oil, as well as setting alarm targets for water levels in oil. Where does water come from?

USED ENGINE OIL ANALYSIS USER INTERPRETATION GUIDE - cimac.c

The system oil in large medium and low speed diesel engines is intended to be in use for a long time. The normal case is that the lubricating oil stays in the engine without replacement. Only the loss of oil, e.g. consumption during operation and loss of oil in the cleaning system, is compensated for by the topping up the volume with new oil.
