Hydraulic transmission oil
It is mainly used for hydraulic torque converter and hydraulic coupler of large vehicles such as diesel locomotive, heavy duty truck, track vehicle and off-road vehicle. It can also be used for hydraulic transmission system of construction machinery.
1.Product Introduction
Energy transmission: In hydraulic systems, power is transmitted through the pressure energy of hydraulic oil, driving various hydraulic components such as hydraulic cylinders and hydraulic motors to operate and realize various mechanical actions.
Lubrication protection: It can form an oil film between the moving parts of hydraulic components, reducing wear, lowering the friction coefficient, and prolonging the service life of the components.
Sealing function: It helps maintain good sealing performance at each sealing part in the hydraulic system, preventing oil leakage and ensuring the normal working pressure of the system.
Cooling and heat dissipation: During the system's operation, hydraulic oil can absorb and dissipate the heat generated by friction, throttling, etc., playing a role in cooling and heat dissipation, keeping the system temperature within a reasonable range.
2.Characteristic
Suitable viscosity and good viscosive-temperature performance to ensure the normal operation of the hydraulic transmission device in the temperature range of -40 ~ 170ºC.
Good wear resistance to ensure that the hydraulic transmission parts of different materials are not easy to be worn under operating conditions.
Good thermal stability and antioxidant stability, to adapt to the long-term recycling under 70 ~ 140ºC (or even higher) working conditions.
Good low temperature fluidity, low freezing point, in order to adapt to the mechanical time on and off and winter operation of the working conditions.
Good foam resistance, so that the oil products under the working conditions of mechanical constantly stirring foam is easy to disappear. So as not to reduce the efficiency of the converter, so that the shift failure
