Hydraulic Oil Viscosity of Hydraulic Wrench Pump

Hydraulic oil viscosity of hydraulic wrench pump is an important index of hydraulic oil. Small viscosity will increase leakage and reduce volumetric efficiency. Viscosity will cause loss of viscosity and cause cavitation or seizure. Generally, the kinematic viscosity of hydraulic oil used in hydraulic system is 106m/s. The detailed indexes required for viscosity of hydraulic [...]
