AI Technical Summary

Technical Problem

Existing hydro-generator units suffer from oil slingshot and oil mist overflow when using turbine oil, which affects equipment and personnel health. Furthermore, traditional lubricating oils are difficult to meet the environmentally friendly requirements for low oil mist.

Method used

An environmentally friendly turbine lubricating oil composition is adopted, which includes antioxidants, acid anhydride derivatives, viscosity index improvers, metal passivators, demulsifiers, antifoaming agents and extreme pressure antiwear agents. The compound system reduces oil mist generation and enhances water separation capacity and antioxidant performance.

Benefits of technology

It achieves low oil mist generation, strong water separation capability, good anti-oxidation performance, reduces the generation of sludge and varnish, meets the environmentally friendly requirements of water turbines, and has good compatibility and stability.
