The Lubricant Film-Forming Properties of Modern Fire Resistant Hydraulic Fluids

Source

Fire resistant hydraulic fluids tend to show significantly poorer ribological performance in hydraulic systems than conventional mineral oil-based fluids. There have recently been performance problems associated with increases of operating temperatures of mining hydraulics. This paper describes measurements of the elastohydrodynamic and boundary film-forming properties of a range of different hydraulic fluid types at temperatures up to 80°C. These are compared with friction and wear results obtained using the same fluids.
