Abstract

The invention discloses a turbine oil composition, and a preparation method and application thereof. The invention mainly aims to solve the technical problem that conventional turbine oil compositionshave poor demulsifying performance. The turbine oil composition provided by the invention comprises the following components in parts by weight: 0.5 to 2 parts of a composite additive, 0.01 to 0.5 part of an antirust agent, 0.001 to 0.05 part of an anti-foaming agent, and 97 to 99.5 parts of base oil, wherein the composite additive is at least one selected from the group consisting of IRGOLUBE 2030D, Hitec 2584A and RP-T6012. The invention also discloses the preparation method of the turbine oil composition. The corresponding preparation method comprises the following step: stirring the composite additive, the antirust agent, the anti-foaming agent and the base oil for 0.5-2 hours at a temperature of 50-80 DEG C to completely dissolve the above components so as to obtain the turbine oil composition. The invention further discloses the application of the turbine oil composition in turbines. Thus, the above problems are well solved. The turbine oil composition is suitable for lubrication industrial application in turbines, and is especially suitable for steam turbine units and large combined cycle units.

Description

technical field [0001] The invention relates to a turbine oil composition, a preparation method and an application thereof. Background technique [0002] With the rapid development of turbine design and manufacturing technology and the national power industry, turbines are developing towards large-capacity, high-efficiency steam turbine units and large-scale combined cycle units. The steam temperature and working pressure of steam turbines are increasing, and the workload is increasing. The heavier the oil, the higher the requirements for the anti-rust performance of the turbine oil. [0003] The most effective way to improve the anti-rust performance of turbine oil is to add suitable anti-rust agents to the oil, and the anti-rust effects of different types of anti-rust agents in turbine oils vary greatly. Existing turbine oil antirust agents such as T746 (dodecenyl succinic acid) show good antirust performance, but the strong polarity of its dicarboxylic structure will red...
