Definitions
- This invention relates to fluid compositions useful especially for transmitting energy in mechanical systems and, more particularly, to water-based compositions useful in transmitting hydraulic energy having enhanced lubricity and anti-wear properties.
- Water-based hydraulic fluids are well known and have been used commercially for a number of years especially in applications where fire resistance is desired.
- One commonly used class of ' such water-based fluids as disclosed, for example, in U.S. Patent No. 2,602,780 to Zisman et al. and U.S. Patent No. 2,768,141 to Langer et al., contain water soluble glycols or glycol ethers for low temperature protection and a high molecular weight polymeric thickener such as water soluble poly(alkylene oxide) polymers for viscosity control.
- Such compositions also contain a variety of additives in "packages” that are added to enhance lubrication, corrosion protection, and other performance characteristics necessary for hydraulic devices and lubricants.
- Water based hydraulic fluids commonly have high noninflammability, good temperature stability, and a -relatively low cost, but generally have poorer anti-wear characteristics than petroleum-based fluids. Fluids used in energy transmission systems must possess sufficient lubricity and mechanical stability to enable them to be used in the self-lubricated pumps, valves etc. employed in commercial hydraulic systems. Good lubricating properties, especially good lubricity and film strength, are particularly important in reducing the wear of moving components of hydraulic systems where the clearance between frictional surfaces may be very small and pressures may be very high.
