Problems solved by technology

[0003] First of all, after the turbine oil exposed to high temperature is oxidized, it is easy to form varnish deposits, which affects the normal operation of the unit
[0004] In addition, under high temperature conditions, the oil film at the bearing bush of the equipment becomes thinner and the wear is more serious
In the past, the service life of turbine oil in modern turbines is greatly shortened, and frequent oil changes cause a lot of economic losses and waste oil pollution

Abstract

The invention discloses a turbine oil composition and a preparation method thereof, and mainly relates to the technical field of lubricating grease. The lubricating oil is prepared from the following raw materials in parts by weight: 90 to 99.5 parts of synthetic base oil, 0.6 to 1.0 part of a composite additive, 0.3 to 1.0 part of an amine antioxidant additive, 0.01 to 0.1 part of an extreme pressure additive, 0.001 to 0.005 part of a de-foaming agent and 0.001 to 0.005 part of a demulsifying agent, the synthetic base oil is prepared from the following components in parts by weight: 40 to 80 parts of PAO6, 5 to 40 parts of PAO40 and 10 to 30 parts of alkyl naphthalene AN5. The invention has the following beneficial effects: the viscosity index is very high, the volatility is low, the viscosity index is very wide, and the service life is very long.

Description

technical field [0001] The invention relates to the technical field of lubricating grease, in particular to a turbine oil composition and a preparation method thereof. Background technique [0002] The normal operation of the turbine unit requires the cooperation of oil. Based on the continuous improvement of the working parameters of the turbine unit, the main steam of the steam turbine can reach 720 ℃, 35Mpa, the inlet temperature of the gas turbine is increased to 1600 ℃, and the working temperature of the turbine bearing will increase accordingly. Existing oil products expose the following problems when operating with turbines: [0003] First, after the turbine oil exposed to high temperature is oxidized, paint film deposits are easily formed, which affects the normal operation of the unit. [0004] Furthermore, under high temperature conditions, the oil film at the bearing bush of the equipment becomes thinner and the wear becomes more serious. The service life of th...
