Abstract

The invention discloses an environment-friendly extreme-pressure anti-wear anti-flame turbine oil composition. Trimethylolpropane trioleate with a mass ratio of 80% and pentaerythritol tetradodecanoate (PETD) with a mass ratio of 20% are compounded as total-synthesis compound base oil, the total-synthesis compound base oil is matched with varieties of compound additives, and the compound additives include an antioxidant, a metal activating agent, an anti-wear agent, a friction modifier, an anti-rust agent, an anti-foaming agent, an antioxidant preservative and a viscosity index improver. The composition disclosed by the invention has the characteristics of good oxidation stability and anti-rust property, foam resistance, demulsibility, extreme pressure, air release performance and environmental friendliness.

Description

technical field [0001] The invention relates to an environment-friendly extreme-pressure anti-wear and anti-combustion turbine oil composition, which belongs to the field of turbine lubricants. Background technique [0002] The working principle of a steam turbine is based on the process of converting thermal energy of steam (gas) into mechanical energy. According to its working principle, it can be divided into two types: impulsive and reactionary. Turbine oil is mainly used as a lubricant for the main shaft and auxiliary machine of various steam turbines. With the development of modern technology, the steam (gas) and working pressure of steam turbines are constantly increasing, and the installed capacity is also increasing, which makes the oil temperature in steam turbines higher and higher, so the requirements for steam turbine oil are more stringent. In addition to ensuring good oxidation stability and rust resistance, it should also have anti-foaming, anti-emulsifying...
