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?


Lubrication is used for both cooling and lubricating in marine diesel engines which are used for producing electricity and propulsion system on ships. Furthermore, lubrication oil is cooled with both sea water and fresh water in conventional and central cooling systems, respectively. In this study, friction behaviours are

How Water Affects Synthetic Lubrican

While it is true that some synthetic lubricants have greater water-holding abilities than others, this will depend on the application of the oil. Whether it is a hydraulic fluid, combustion engine, compressor/chiller or gearbox oil, most synthetic lubricants have a greater ability to handle water than mineral oils do.

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.
