The difference between the definition of hydraulic oil and turbine oil.
Hydraulic oil is the hydraulic medium used in hydraulic systems that utilize liquid pressure energy. It plays the roles of energy transmission, anti-wear, system lubrication, anti-corrosion, anti-rust, and cooling in the hydraulic system.

Turbine oil usually includes steam turbine oil, gas turbine oil, hydraulic turbine oil and antioxidant turbine oil, etc. It is mainly used for turbine oil and sliding bearings, reduction gears, governors and hydraulic control systems of linked units lubrication. The main functions of turbine oil are lubrication, cooling and speed regulation.

Second, the difference between hydraulic oil and turbine oil requirements
Quality requirements for hydraulic oil
1) Appropriate viscosity and good viscosity-temperature performance to ensure accurate and sensitive transmission of power under the condition of changing working temperature, and to ensure normal lubrication of hydraulic components.
2) It has good anti-foaming property, so that under the working condition of continuous mechanical stirring of oil, the generated foam is easy to disappear, so as to stabilize the power transmission and avoid the accelerated oxidation of hydraulic oil.
3) It has good anti-rust and anti-oxidation stability, is not easy to oxidize and deteriorate under high temperature and high pressure conditions, and has a long service life.

Performance Requirements for Turbine Oils
According to the function characteristics of turbine oil, in order to ensure the safe and economical operation of the turbine unit, the turbine oil must have:
Good oxidation stability; Appropriate viscosity and good viscosity-temperature; Good demulsibility; Good rust and corrosion resistance;
Good anti-foaming and air release properties.

Application of hydraulic oil
1. Industrial hydraulic system
Hydraulic fluids are used in all types of hydraulic systems in manufacturing and industry.
2. Mobile hydraulic transmission system
Hydraulic fluids are effective for mobile hydraulic equipment such as excavators and cranes.
3. Marine hydraulic system
Suitable for marine hydraulic systems where ISO HM hydraulic fluids are recommended.
