The working medium of hydraulic system shall have the following characteristics:
1. Suitable viscosity;
2. Good lubrication performance;
3. Good compatibility with metals and seals;
4. Good stability to heat, oxidation, hydrolysis and shearing;
5. Good foam resistance, good emulsification resistance, low corrosiveness and good rust resistance;
6. Small volume expansion coefficient and large specific heat capacity;
7. Low flow point and freezing point;
8. Harmless to human body and low cost;
9. Compatibility with products and environment;
10. Pure texture, less impurities;
The hydraulic system should choose the appropriate brand of hydraulic oil according to its own working conditions, not to mention that the rolling oil additive is not hydraulic oil.
If you use rolling oil additives instead of hydraulic oil, there should be no advantage (if you are a manufacturer of rolling oil additives, the only advantage may be that the materials are convenient and the price is low, haha); Disadvantages may not be seen in the short term, but in the long run, it will cause some damage to pumps, hydraulic cylinders, seals and control valves.
