Which is better, hydraulic oil No. 46 or No. 68?

There is no absolute conclusion as to whether the hydraulic oil is better with No. 46 or No. 68. These two different hydraulic oils are determined according to specific usage conditions. They are suitable for different working environments. If the temperature is relatively high In the environment, it is more appropriate to use No. 68 hydraulic oil, and it is more appropriate to use No. 46 when the temperature is relatively low.

The difference between No. 46 and No. 68 hydraulic oil

1. Compared with No. 46 and No. 68 hydraulic oil, there are differences mainly in the seasons of use. 46 is suitable when the temperature is low, and 68 is suitable for high temperature.

2. Compared with No. 46 and No. 68 hydraulic oil, there is a difference in viscosity. No. 68 hydraulic oil is more viscous than No. 46 hydraulic oil. This is also the main reason why the temperatures used by these two types of hydraulic oil are different. The viscosity of No. 46 hydraulic oil is lower than that of No. 68. If it is used at a high temperature, the viscosity will decrease, the pressure of the entire system will decrease, and leakage may occur.

The difference between hydraulic oil and engine oil

1. Hydraulic oil is what we usually sayBrake FluidIt is almost the same, mainly to provide brake pressure for the car, and the oil is to protect the engine.

2. The composition of hydraulic oil and engine oil is different. Hydraulic oil contains certain antioxidant components and anti-wear components, and engine oil has certain clean components.

3. The density of hydraulic oil is not as large as that of engine oil, and the viscosity is not as high as that of engine oil.

4. The color of hydraulic oil is lighter than that of engine oil.

5. The hydraulic oil is to provide power for the equipment, but the engine oil is to clean and lubricate.
