The difference between No. 32 hydraulic oil and No. 46 hydraulic oil
Hydraulic oil is the working medium in the hydraulic system, and its main role is to transfer energy, lubricate and protect hydraulic components. In the hydraulic system, the selection and use of hydraulic oil plays a vital role in the performance and life of the entire system. This article will detail the difference between No. 32 hydraulic oil and No. 46 hydraulic oil.
1. Viscosity. Viscosity is one of the important indicators of hydraulic oil, which reflects the fluidity and lubricity of hydraulic oil. No. 32 hydraulic oil has low viscosity and good fluidity, making it suitable for low temperature or low load conditions. On the other hand, No. 46 hydraulic oil has a higher viscosity and poor fluidity, making it suitable for high temperature or high load conditions.
Second, pressure. In hydraulic systems, pressure is a key factor in the transfer of energy. No. 32 hydraulic oil is suitable for use in low-pressure systems and generally operates at pressures between 20 and 40 bar. Hydraulic oil No. 46 is suitable for high-pressure systems and generally works at pressures between 40 and 60 bar.
3. Temperature. Temperature is one of the important factors that affect the performance of hydraulic fluids. No. 32 hydraulic oil is suitable for low temperature environments, and its operating temperature is generally between 0-50. The No. 46 hydraulic oil is suitable for high temperature environments, and its working temperature is generally between 50-80.
Fourth, corrosiveness.
Hydraulic oil has a certain corrosive nature, which will have a certain corrosive effect on hydraulic components. No. 32 hydraulic oil is less corrosive and less corrosive to metal components. The No. 46 hydraulic oil is more corrosive and has a strong corrosive effect on metal components.
5. Additives.
In order to improve the performance and service life of hydraulic oil, some additives are usually added to the hydraulic oil. No. 32 hydraulic oil has fewer additives added and mainly plays a lubricating and antioxidant role. There are many additives added to No. 46 hydraulic oil, which not only has lubrication and anti-oxidation effects, but also has anti-wear and anti-rust effects.
6. Scope of application.
No. 32 hydraulic oil is suitable for some low-temperature, low-load, low-corrosive hydraulic systems. The No. 46 hydraulic oil is suitable for some high-temperature, high-load, high-corrosive hydraulic systems. In actual use, the appropriate hydraulic oil should be selected according to the specific working conditions.
In conclusion, there are obvious differences between No. 32 hydraulic oil and No. 46 hydraulic oil in terms of viscosity, pressure, temperature, corrosivity, additives and scope of application. When selecting and using hydraulic oil, it should be selected according to specific working conditions and equipment requirements to ensure the normal operation and service life of the hydraulic system.
