From the temperature/viscosity diagram, exhibit 1, it can be seen that to maintain viscosity above the minimum, optimum value of 16 centistokes at 75°C, an ISO VG68 hydraulic oil is required. At a starting temperature of 15°C, the viscosity of VG68 oil is 300 centistokes, which is...

A leakage model of pistoncylinder pair in a high pressure aviation hydraulic pump is presented in this paper,considering the pressure-viscosity properties of oil. Combined with the Barus pressure-viscosity properties formula,this model is supplemented and modified to a certain extent on the basis of...
Temperature influences the properties of the hydraulic oil—mainly viscosity—significantly. At low temperatures, the viscosity is high and pressure drops accordingly high as well; this leads to lower efficiencies, which was investigated in [87] for an EHA in sub-zero conditions, but more ...
