二、TEXT
(1) the purpose of the oxygen system is to provide oxygen for the flight crew and passengers when required. Two independent oxygen system are installed in B737. the flight crew oxygen system is a high pressure gaseous system for flight crew use only, this type of system is designated a “diluter demand” system . The passenger oxygen system is a chemically-generated oxygen system for use by passengers and cabin attendants. This type of system is designated a “continuous flow” system.
氧气系统用来为机组及旅客提供氧气。 B737上安装有两套氧气系统。机组氧气系统是一个仅供机组使用的高压气态系统,这种系统被称为“稀释要求”系统。旅客氧气系统是一供旅客及乘务员使用个化学制氧系统。这种系统被称为“ continuous flow”系统。
(2) The flight crew oxygen system consists of an oxygen cylinder. Valves, indicating components, distribution tubing and oxygen mask/regulator. The crew oxygen system components are located in the forward cargo compartment and in the flight compartment.
机组氧气系统包括一个氧气瓶,阀门,指示组件,分配管道及氧气面罩/调节器。机组氧气系统组件安装在前客舱和驾驶舱内。
(3) Oxygen flows through the pressure reducing regulator and shut off valve
to the masks. Quantity (pressure) indication is provided by a gage in the flight compartment. In the event of an overpressure, the cylinder is vented to ambient through the overboard discharge. The cylinder is serviced after removal from the aircraft.
氧气通过减压调节器和关断活门流向氧气面罩。流量指示由驾驶舱内的压强计指示。一旦过压,气瓶将通过顶部释放开关进行释压。气瓶应从飞机上取下进行勤务。
(4) The passenger oxygen system provides an emergency oxygen supply to the passengers and attendants, this system consists of passenger sevice units, control and indication. This service units contain the mask box, door latch release actuator, latching mechanism, chemical oxygen generator and oxygen mask.
