Problems solved by technology

[0003] Although the oxidation stability and anti-emulsification properties of various turbine oils formulated with mineral oils on the market can reach the level suitable for turbines, they are prone to carbon deposits at high temperatures and have insufficient cleaning ability, so they are not suitable for combined cycle turbines that operate simultaneously with gas and steam use
At the same time, the turbine equipment using the turbine oil needs to be disassembled and cleaned frequently, and the maintenance cost is high. At the same time, the service life of the turbine oil is short and the use cost is high

Abstract

The invention relates to high-cleanliness extreme-pressure turbine oil. The turbine oil is prepared from synthetic base oil, a high-temperature antioxidant, a detergent dispersant, a friction modifier, an extreme-pressure antiwear agent, a viscosity index improver, a pour point depressant and an antirust agent; the synthetic base oil is obtained by mixing PAO4, PAO10 and diester. According to the technical scheme, the high-cleanliness extreme-pressure turbine oil has the excellent detergency, high oxidation stability and demulsibility, high bearing capacity, high anti-rust and anti-corrosion capacities and rapid air release and foam formation resistant characteristics, and the high-cleanliness extreme-pressure turbine oil can be suitable for combined cycle turbines operating with steam or gas or gas and steam at the same time.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to a high-cleanness extreme-pressure turbine oil. Background technique [0002] Turbine oil is mainly used in steam turbines in power plants, hydroelectric generators in hydropower stations and other lubricating occasions that require highly refined lubricating oil. Turbine oil is a kind of oil used in steam turbine engines, which is suitable for high-speed mechanical lubrication, and mainly plays the role of lubrication, heat dissipation, cooling and speed regulation. The most important part of the turbine is the rotating element (rotor or impeller), which is mounted on the turbine shaft and has blades arranged uniformly along the circumference. The energy of the fluid is converted into kinetic energy when it passes through the nozzle in the flow, and when it flows through the rotor, the fluid impacts the blades, pushing the rotor to rotate, thereby driving the turbine shaft to rota...
