Embodiment Construction

[0020] The specific implementation of the present invention will be further described below in conjunction with the examples. It should be noted here that the descriptions of these embodiments are used to help understand the present invention, but are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not constitute a conflict with each other.

[0021] The invention provides a steam turbine lubricating oil composition, wherein it mainly consists of the following materials by weight:

[0022]

[0023] Wherein, the base oil includes 70% to 80% of Group III base oil, 10% to 20% of polyethylene glycol ether and 10% to 20% of rosin pentaerythritol ester. Group III base oil is produced by full hydrogenation process. Compared with Group II base oil, it is a hydrogenated base oil with high viscosity index, also known as uncon...

Abstract

The invention discloses a steam turbine lubricating oil composition. The composition is prepared from the following materials, by weight: 100 parts of base oil, 0.1-2 parts of a demulsifier, 2-4 partsof a extreme pressure anti-wear agent, 0.5-1 part of a deactivator, 1-3 parts of an antioxidant, 0.5-2 parts of an antirust agent, and 0.05-0.5 part of an antifoaming agent. The base oil includes 70%-80% of III base oil, 10%-20% of polyglycol ether, and 10%-20% of pentaerythritol ester of rosin. Through performing optimization on the formula of the lubricating oil, the oxidation stability, the high temperature stability, the extreme pressure performance, the demulsification performance and the liquid phase antirust performance of the lubricating oil are improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of steam turbine lubricating oil, in particular to a steam turbine lubricating oil composition. Background technique [0002] Steam turbines are one of the main equipment in the power generation industry, and the power drives include gas, steam, hydraulic and other forms. A steam turbine is a high-speed rotary thermal power machine that converts steam heat energy into rotary mechanical energy. Its lubricating parts are mainly gearboxes and rotor bearings. Because the rotor shaft seal may escape steam, the possibility of water entering the lubrication system is relatively high. In addition, the equipment has high speed, heavy load, and long operating cycle, so the rust resistance, emulsification resistance and oxidation resistance of oil products Sexual demands are high. Gas turbines use the gas produced by combustion to do work directly, unlike conventional steam turbines that generate steam through combustion and h...
