1、.空軍裝備美孚飛馬254潤滑油（Mobil Jet Oil 254）（中英文介紹）美孚飛馬254航空潤滑油特征 優點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降低了碳和污泥沉積物的形成保持發動機的效率，延長發動機壽命散裝油氧化減少 50%，并增加存款控制 50FExcellent wear and corrosion protectionExtends seal, gear and bearing lifeReduces engine maintenance延長了密封，齒輪和軸承壽命

8、trength under rigorous operating conditions保持嚴格的操作條件下的膜強度Good low temperature fluidityPermits start-up and ensures effective lubrication of critical components at temperatures as low as -40F允許啟動并確保有效潤滑的關鍵部件在溫度低至-40 F應用：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潤滑油推薦用于渦輪噴氣飛機的燃氣渦輪發動機，渦輪風扇，渦輪螺旋槳和渦輪軸（直升機）商用和軍用服務使用的類型。它也適用于工業或海洋的應用程序中使用的飛機類型燃氣渦輪發動機。美孚254潤滑油被批準為美國軍用標準MIL-PRF-23699的熱穩定

12、性高（HTS）的分類。它還與滿足MIL-PRF-23699等合成燃氣渦輪潤滑油兼容。然而，與其他產品的混合是不推薦的，因為該共混物將導致美孚噴氣機油254.Mobil噴氣機油254的性能優越的特性的一些損失是在燃氣渦輪機結構中使用的所有的金屬完全兼容，以及具有F橡膠（氟橡膠一），H橡膠（丁腈橡膠），以及其他常用的密封材料。規范：Mobil Jet Oil 254 has the following builder approvalsEngines-Honeywell/Lycoming-TurbinesX-Rolls-Royce/Allison Engine CompanyX-CFM Inter
