Description
Technical Field
The invention relates to a turbine oil composition, a preparation method and application thereof.
Background
With the development of turbine technology, supercritical steam turbines, gas turbines and steam-gas combined cycle units are applied, and the working temperature of bearings is increased accordingly. After turbine oil exposed to high temperature is oxidized, oil sludge deposits are easily generated, and normal operation of a unit is affected. Meanwhile, under the condition of high temperature, an oil film at the bearing bush of the equipment becomes thin, so that oil products are more easily oxidized. The increase in bearing operating temperature requires turbine oils to have good oxidation resistance. In addition, some units have a wide working temperature range and work in extreme cold or high temperature, which requires that the used oil has the characteristics of low pour point and high viscosity index. Meanwhile, the turbine oil also has excellent antirust property, foam resistance and air release property. At present, the rotating oxygen elasticity value of the better turbine oil used industrially is generally 1200-1400 min, the viscosity index is about 120, the pour point is about-15 ℃, the air release value is 2-3 min, and the anti-foaming property is less than 50/0. The lower the pour point value, the wider the range of use.
Document CN109135894A discloses a turbine oil composition and application thereof, wherein the turbine oil composition comprises 0.3-0.9 part of alkylated diphenylamine and alkyl phenyl-alpha-naphthylamine antioxidant, 0.05-0.2 part of metal deactivator, 0.05-0.1 part of antirust agent, 0.03-0.05 part of dispersant, 0.01-0.05 part of demulsifier, 0.003-0.005 part of anti-foaming agent and the balance of hydrogenated base oil. The invention has the advantages that: the antioxidant performance is excellent, and the rotary oxygen bomb value reaches 1260 min; TOST oxidation life is more than 12000 hours; the generation tendency of the sludge is very small, and the generation amount of the sludge is less than 60mg/kg in a Dry-TOST test at 120 ℃ when the residual rotary oxygen elastic rate is 25 percent.
Document CN103571577A discloses a turbine lubricating oil composition, which comprises 0.1-5 parts of antioxidant, 0.1-5 parts of extreme pressure antiwear agent, 0.01-1 part of detergent dispersant, 0.01-1 part of antirust agent, 0.01-2 parts of metal deactivator, 0.001-1 part of demulsifier, 0.001-0.1 part of antifoaming agent, and the balance of base oil. The invention has excellent oxidation resistance, and also has excellent anti-foaming property and anti-emulsifying property. The TOST oxidation life of the steam turbine oil is more than 16000 hours; the 24 ℃ foam characteristics (foam tendency/foam stability) were 10/0, and the time required for the emulsion layer to decrease to 3ml in the demulsibility test at 54 ℃ was 5 min.

The addition amount of the demulsifier is 0.01-0.1%, and the demulsification effect cannot be realized when the addition amount is too large or too small.
In the above technical solution, preferably, the demulsifier is selected from at least one of L61, T-1001, PE6100, and LZ 5957; the antifoaming agent is at least one selected from FOAM BAN 130B, T911 and AMH 2.

In order to solve the third technical problem, the technical scheme adopted by the invention is as follows: a turbine oil composition is used for lubricating a steam turbine, a gas turbine and a steam-gas combined cycle unit.
The base oil in the turbine oil composition disclosed by the invention is HVIII + synthetic base oil, does not contain aromatic hydrocarbon and sulfur and nitrogen elements, has good oxidation resistance and deposit inhibition capability, and has good additive sensitivity, so that the prepared turbine oil composition has the characteristics of high viscosity index (14) and low pour point (51 ℃ below zero, and can be used under extremely cold conditions). The antioxidant selected in the invention has excellent oxidation life and strong sediment inhibition capability. The base oil with good performance is matched with an excellent antioxidant, so that the turbine oil composition has stronger antioxidant performance and deposit inhibition capacity. The hviiii + base oil gives the turbine oil composition of the present invention excellent viscosity temperature characteristics and low temperature fluidity, which are important for maintaining the oil film thickness of the bearing surface, providing good lubrication. Because the preferable antifoaming agent is added, the air release performance of the oil product is not influenced while the good anti-foaming performance is ensured, and a good technical effect is achieved.
To evaluate the overall performance of this composition, the following evaluation tests were carried out:
the lubricating oil viscosity index test (GB/T1995), the pour point test (GB/T3535), the oxidation stability test (SH/T0193(150 ℃)), the rust prevention test (GB/T11143 (B method)), the air release test (SH/T0308) and the anti-foaming test (GB/T12579).
