XXXXXXX学院毕业论文B737飞机燃油系统的故障及维护姓名：专业：航空机务学号：完成日期：指导教师:摘要燃油系统是飞机主要系统之一，其工作性能的好坏，直接影响着飞机的起飞和飞行的安全。燃油系统是用来为发动机和APU储存和提供燃油的,主要有储存、供油、分配、抽油和指示等几部分组成。飞机上用来存储和向发动机连续供给燃油的整套装置,又称外燃油系统或加油装置,以及在紧急时,将机身内的燃油排放于机外的燃油排放装置。另外,为使燃油箱内液面压力与外气压相等,所装设的燃油通气系统等各种系统及指示仪表装置组成。本文通过介绍B737飞机燃油系统，使机务人员能更加全面的了解飞机的这个胃，从而提高对B737系列飞机的燃油系统维护有更好的认识。关键词:燃油系统、加油装置、燃油排放、燃油通气系统AbstractThefuelsystemisoneofairplanemainsystems,itsoperatingperformancequality,immediateinfluenceairplane'slaunchingandflightsecurity.ThefuelsystemisusesfortheengineandAPUstoresupandprovidesthefueloil,mainlyhasthestorage,feed,theassignment,theoilpumpingandtheinstructionandsoonseveralpartsofcompositions.Ontheairplaneusesfortosaveandsuppliesthefueloilcontinuouslytotheenginewholesetinstallment,alsooutsidethenamethefuelsystemorrefuelstheinstallment,aswellaswhenurgency,fuselageinfueloilemissionsinoutsidetheaircraft'sfueloilemissionsinstallment.Moreover,tocauseinthefueloiltanktheliquidlevelpressuretobeequalwiththeoutsidebarometricpressure,installsfueloildrainagesystemandsooneachkindofsystemandindicatinginstrumentequipmentcomposition.ThisarticlethroughintroducedthattheB737airplanefuelsystem,enablesthecrewsmorecomprehensiveunderstandingairplane'sthisstomach,thusenhancestotheB737seriesairplane'sfuelsystemmaintenancehasabetterunderstanding.Keyword:Thefuelsystem,refuelstheinstallment,thefueloilemissions,thefueloildrainagesystem目录TOC\o"1-4"\h\z\uHYPERLINK\l"_Toc230109749"摘要PAGEREF_Toc230109749\h1HYPERLINK\l"_Toc230109750"ABSTRACTPAGEREF_Toc230109750\h2HYPERLINK\l"_Toc230109751"1.B737飞机燃油系统概述6HYPERLINK\l"_Toc230109752"1.1燃油系统的功用6HYPERLINK\l"_Toc230109756"1.2燃油系统的特点6HYPERLINK\l"_Toc230109757"1.3燃油系统的组成7HYPERLINK\l"_Toc230109767"1.4燃油系统的形式8HYPERLINK\l"_Toc230109767"1.5加油系统的目的8HYPERLINK\l"_Toc230109759"2．供油8HYPERLINK\l"_Toc230109760"2.1燃油系统的供油方式8HYPERLINK\l"_Toc230109761"2.2燃油系统的供油顺序9HYPERLINK\l"_Toc230109757"2.3B737飞机燃油供油系统(双发动机)10HYPERLINK\l"_Toc230109766"3.加油/抽油系统.12HYPERLINK\l"_Toc230109767"3.1加油
