Detailed introduction:
Product Introduction:
Hydraulic transmission oil is a high-quality hydraulic oil that has a higher viscosity index, thermal oxidation stability, anti-wear properties, and higher cleanliness to meet the working conditions of hydraulic torque converters and hydraulic couplings.
Suitable viscosity and good viscosity temperature performance ensure that the hydraulic transmission device operates normally within the temperature range of -40~170 ℃.
Good wear resistance ensures that hydraulic transmission components made of different materials are not easily worn under operating conditions.
Good thermal stability and antioxidant safety, suitable for long-term cyclic use under working conditions of 70-140 ℃ (or even higher).
Good low-temperature fluidity and low freezing point, suitable for working conditions such as mechanical on-off and winter operation.
Good foam resistance makes the foam produced by oil products under the working condition of continuous mechanical agitation easy to disappear. To avoid reducing the efficiency of the torque converter and causing gear shifting failure.
1. Viscosity: Based on typical hydraulic transmission oil, the temperature range for use is about -25~170 ℃, requiring the oil to have a high viscosity index and low solidification
Point, the general specifications stipulate a viscosity index of 170 or above, a pour point of -40 ℃, and synthetic oils at 190 ℃ and -50 ℃.
2. Thermal oxidation stability: The temperature of hydraulic transmission oil varies with different vehicle conditions during driving. Oil generated by oxidation due to increased oil temperature
Mud, paint film, etc. can cause abnormal operation of hydraulic systems, deterioration of lubrication performance, and corrosion of metals.
3. Shear stability: When hydraulic transmission oil transmits power in a hydraulic torque converter, it will receive strong shear force, which will cause viscosity index improvers and the like in the oil
The polymer compound breaks, causing the viscosity of the oil to decrease and the oil pressure to drop, resulting in clutch slippage.
4. Anti foam performance: when foam is mixed in the hydraulic transmission oil, the oil pressure will be reduced, resulting in clutch slip, sintering and other accidents.
5. Friction performance: Advanced automatic transmission fluids require matching static and dynamic friction coefficients to adapt to different friction coefficient requirements during clutch shifting.
