Wear-resistant Hydraulic Oil

Hydraulic wrenches usually use 46 and 32 wear-resistant hydraulic oil. Viscosity of hydraulic oil is an important index of hydraulic oil. Low viscosity increases leakage and decreases volumetric efficiency; high viscosity increases viscous friction loss and even causes cavitation or stagnation. Generally, the mobility of hydraulic oil used in hydraulic system is l06m/s (50C). Characteristics [...]
