美孚飞马254航空润滑油(Mobil Jet Oil 254)中英文介绍

1、.空军装备美孚飞马254润滑油（Mobil Jet Oil 254）（中英文介绍）美孚飞马254航空润滑油特征 优点Mobil Jet Oil 254 is formulated to meet the demanding requirements of latest technology aircraft-type gas turbines operating over a wide range of severe operating conditions. When compared to a typical Type II lubricant, Mobil Jet Oil 254 red

2、uces bulk oil oxidation by up to 50 percent and shows deposit control capability 50 F higher. These properties have been confirmed in various laboratory tests including; the Corrosion-Oxidation Stability Test, Alcor Deposition Test, Vapor Phase Coker, Erdco High-Temperature Bearing Test, Ryder Gear

3、and the Mobil Thin Film Oxidation Test.The closely controlled low-temperature viscosity of Mobil Jet Oil 254, along with its low pour point (below -54C), ensure good low-temperature fluidity to permit starting and lubrication at temperatures as low as -40C. In extensive laboratory testing and in-fli

4、ght experience, Mobil Jet Oil 254 also exhibits excellent bulk oil stability at temperatures up to 232C (450F) for extended periods. The evaporation rate at these temperatures is low enough to prevent excessive loss of volume. The load-carrying ability of Mobil Jet Oil 254 comes from its synthetic b

5、ase stock viscosity and, therefore, is not subject to loss from viscosity index additive shear. The lubricant has excellent resistance to foaming. Key features and benefits include:FeaturesAdvantages and Potential BenefitsExcellent thermal and oxidation stabilityReduces the formation of carbon and s

6、ludge depositsMaintains engine efficiency and extends engine lifeReduces bulk oil oxidation by 50% and increases deposit control by 50F降低了碳和污泥沉积物的形成保持发动机的效率，延长发动机寿命散装油氧化减少 50%，并增加存款控制 50FExcellent wear and corrosion protectionExtends seal, gear and bearing lifeReduces engine maintenance延长了密封，齿轮和轴承寿命

7、降低发动机维修Viscosity and shear stability across wide temperature rangeProvides effective lubrication at high operating temperatures提供在高温操作的有效润滑Chemically stable at high operating temperaturesReduces evaporation losses and lowers oil consumption减少蒸发损失和降低石油消耗Excellent resistance to foamingMaintains film s

8、trength under rigorous operating conditions保持严格的操作条件下的膜强度Good low temperature fluidityPermits start-up and ensures effective lubrication of critical components at temperatures as low as -40F允许启动并确保有效润滑的关键部件在温度低至-40 F应用：Mobil Jet Oil 254 is recommended for aircraft gas turbine engines of the turbo-je

9、t, turbo-fan, turbo-prop, and turbo-shaft (helicopter) types used in commercial and military service. It is also suitable for aircraft-type gas turbine engines used in industrial or marine applications. Mobil Jet Oil 254 is approved against the High Thermal Stability (HTS) classification of U.S. Mil

10、itary Specification MIL-PRF-23699. It is also compatible with other synthetic gas turbine lubricants meeting MIL-PRF-23699. However, mixing with other products is not recommended because the blend would result in some loss of the superior performance characteristics of Mobil Jet Oil 254.Mobil Jet Oi

11、l 254 is completely compatible with all metals used in gas turbine construction, as well as with F Rubber (Viton A), H Rubber (Buna N), and other commonly used seal materials.美孚254润滑油推荐用于涡轮喷气飞机的燃气涡轮发动机，涡轮风扇，涡轮螺旋桨和涡轮轴（直升机）商用和军用服务使用的类型。它也适用于工业或海洋的应用程序中使用的飞机类型燃气涡轮发动机。美孚254润滑油被批准为美国军用标准MIL-PRF-23699的热稳定

12、性高（HTS）的分类。它还与满足MIL-PRF-23699等合成燃气涡轮润滑油兼容。然而，与其他产品的混合是不推荐的，因为该共混物将导致美孚喷气机油254.Mobil喷气机油254的性能优越的特性的一些损失是在燃气涡轮机结构中使用的所有的金属完全兼容，以及具有F橡胶（氟橡胶一），H橡胶（丁腈橡胶），以及其他常用的密封材料。规范：Mobil Jet Oil 254 has the following builder approvalsEngines-Honeywell/Lycoming-TurbinesX-Rolls-Royce/Allison Engine CompanyX-CFM Inter
