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AbstractThe fuel system is one of airplane main systems, its operating performancequality, immediate influence airplane's launching and flight security. The fuelsystem is uses for the engine and APU stores up and provides the fuel oil,mainly has the storage, feed, the assignment, the oil pumping and theinstruction and so on several parts of compositions. On the airplane uses for tosave and supplies the fuel oil continuously to the engine whole set installment,also outside the name the fuel system or refuels the installment, as well aswhen urgency, fuselage in fuel oil emissions in outside the aircraft's fuel oilemissions installment. Moreover, to cause in the fuel oil tank the liquid levelpressure to be equal with the outside barometric pressure, installs fuel oildrainage system and so on each kind of system and indicating instrumentequipment composition. This article through introduced that the B737 airplanefuel system, enables the crews more comprehensive understanding airplane'sthis stomach, thus enhances to the B737 series airplane's fuel systemmaintenance has a better understanding.Key word: The fuel system, refuels the installment, the fuel oilemissions, the fuel oil drainage system目 录摘要 ....................................
