Viscosity of Hydraulic Fluid: As with
lubricating oils, viscosity is the most important
characteristic of a hydraulic fluid and has a significant
impact on the operation of a hydraulic system. If the
viscosity is too high then friction, pressure drop, power
consumption, and heat generation increase. Furthermore,
sluggish operation of valves and servos may result. If the
viscosity is too low, increased internal leakage may result
under higher operating temperatures. The oil film may be
insufficient to prevent excessive wear or possible seizure
of moving parts, pump efficiency may decrease, and sluggish
operation may be experienced.
