二、TEXT
(1) the purpose of the fuel system is to store and deliver fuel to the engine
and APU. The fuel system is subdivided into dotrage, fueling,
distribution and indicating systems.
燃油系统用于贮存并传输燃油给发动机和APU。燃油系统细分为
贮藏、供油、分配及指示系统。
(2) There are 3 tanks for fuel storage and 2 vent surge tanks for temporary
fuel storage. Tank No.1 is located in the left wing, tank No.2 is located
in the right wing and center tank is located in the fuselage under the
passenger cabin. The 2 vent surge tanks are located outboard of the
main tanks. All fuel tanks are fuel tight. Close metal-to –metal fit of all
parts forms the basic seal. Sealing compounds and sealed fasteners are
used on all joints to complete the fluid tight seal. Two of the wing ribs
contain a series of baffle check valves to prevent fuel flow away from
the boost pumps.
燃油系统有3 个贮油箱和2 个用于临时贮油的油箱。1 号油箱位于
左机翼，2 号油箱位于右机翼，中央油箱位于机身客舱下方。2 个
通气均压油箱位于两个主油箱的外侧。Close metal-to –metal fit of
all parts forms the basic seal.所有的油箱都是密封的。所有的接头
处都用密封剂和密封紧固件进行密封。两个翼肋处包括又个连续
的缓冲隔板单向活门，防止燃油从增压泵中流出。
(3) The fueling system provides a means of filling the fuel tanks on the
airplane. Fueling can be accomplished by the use of a single pressure
fueling station through which all tanks can be filled partially or
completely. Alternately, the main tanks(No.1 and No.2) can be filled
through the overwing ports. The center tank can be filled by
transferring fuel from the main tanks using the fuel station.
燃油系统提供一种在飞机上给油箱注油的方式。供油可以通过一
个单压力加油口来完成，通过它，可以为所有的油箱全部或部份
的加油。另一方面，主油箱（1、2 号）可以通过机翼上方口注油。
中央油箱可以用加油站从主油箱中传输来过。
(4) The components associated with the fueling system are the fueling
station located under the right wing leading edge outboard of the
engine, 3 float switches – one for each tank, prevent the tanks from
being overfilled. The tank fueling float switches are located near the
top of e ach tank and sense full tank quantity. The tanks can be filled to
any desired quantity, the float switches sense full tank condition and
automatically stop the fueling. Power requirements are supplied by
ground power, APU or the battery. Pressure fueling can also be done
manually. Maximum fuel pressure is 55 psi.
构成燃油系统的组件有位于右翼前缘襟翼外侧的加油口，3 个浮子
开关-每油箱一个，用来防止油箱过满。浮子开关位于油箱顶部测
量油量。油箱油量可按要求存贮，浮子开关测量油量并能自动停
止加油。电源可由地面电源、APU 或电瓶提供。压力加油也可人
工操作。最大燃油压力为55psi。
(5) The distribution system allows fuel to be supplied to the engines and
APU. In addition, the system can be used for defueling the tanks and
for fuel transfer between the tanks. The distribution system utilizes
pumps, valves and truing for engine and APU feed. The fueling station
is used for defueling and transfer operations which are only possible on
the ground.
燃油分配系统可为发动机及APU 供油。另外，分配系统可用于油
箱放油及油箱之间的输油。分配系统利用泵、阀门及涡轮为发动
机及APU 供油。加油口只能在地面进行放油及输油操作。
(6) Fuel is first supplied to both engines from the center tank and then
from the respective tanks to engines. The crossfeed valve allows fuel
