Water in Grease Condition Monitoring Literature Review
Luleå University of Technology, Department of Engineering Sciences and Mathematics, Machine Elements.
2013 (English)Report (Other academic)
Abstract [en]

The purpose of this paper is to outline the basics of lubricant condition monitoring and relate that to what could potentially be used to monitor the condition of grease and the water content thereof. Some of the physics and principles behind these methods will also be investigated. There is little to no previous published research about condition monitoring of water in grease even though there is considerable research on condition monitoring of grease lubricated bearings. Because of this gap in knowledge, it is an important first step to investigate existing monitoring methods for various lubricants. It could be that new methods will be adapted to measure water content in grease.Methods involving the measurement of the dielectric constant through capacitance, inductance and conduction will be investigated. Various spectroscopic devices will also be investigated ranging from UV to visible to IR wavelength spectroscopy. A brief introduction of several possible future methods will be included as well.Although the effects of water will not be discussed far beyond the consequences, the detection of water and condition monitoring tools will be. Methods of water detection in lubricants will be discussed.
