Type HH oils are usually intended for total losssystems or ve

27、ry light-duty equipment.3.2 Type HL Hydraulic OilsRefined mineral oils or synthetic base stock with improved rust protection and oxidation stabilityfor hydraulic systems where relatively high temperatures and long periods of operation time are expected, and where there is thepossibility of water or

28、humidity that could rust metal parts of the machinery. These oils are intended for use in systems where nometal-to-metal contact is expected between the moving parts. Usually, systems working at low pressures specify HL oils. Somehigh-pressure piston pumps can operate satisfactorily on these oils.3.

29、3 Type HM Hydraulic OilsOils of HLtype with improved anti-wear properties, for general hydraulic systems, especially forthose working at high pressures and where the possibility of metal-to-metal contact between the moving parts exists. Type HM oilsare usually specified for hydraulic systems with va
