PFSK152 3BSE018877R2工控模块系统备件
内容指示器安装在充油阀旁边。在连接从气缸到自动切断阀的管道之前，充注供应经过管路过滤器和爆破片组件。自动切断阀也位于氧气箱组件中，用于在阀门下游的供应管道破裂时切断氧气供应。所有系统管道均由不锈钢或轻合金制成，连接氧气瓶、脱落式面罩装置、治疗出口和面罩快速释放插座的软管除外。图3氧气箱组件第12-6页飞行员操作手册原始版本：2002年2月第12小节氧气系统Hawker 800XP Pro Line 21第三节-系统说明操作氧气从储气瓶输送至左控制台上飞行舱氧气面板上的主供气阀。打开主供应阀允许氧气流向内容物指示器和压力调节器，然后以70 psi的压力流向组合面罩调节器、治疗出口和气压阀。图4左控制台上的飞行舱氧气面板测试乘客供应紧急拉动操作空1/4 1/2 3/4全氧供应按钮氧气飞行员操作手册第12-7页原始版本：2月，2002第12小节氧气系统Hawker 800XP Pro Line 21第三节-系统描述便携式氧气烟雾机Puritan Zep便携式氧气烟雾机组包括一个容量为312升的氧气瓶和一个烟雾面罩。气缸位于固定在飞行舱右控制台后部的夹具中。预修改。252939：气缸顶部通过肘节紧固件固定在面板DA的前表面上。后期修改。252939：气瓶由一个肘节紧固件和铰链支架固定，铰链支架覆盖面板DA上的电源点。第二个闪光灯图5便携式氧气烟雾装置氧气瓶铰链式氧气瓶安装面板DA前桅杆左侧的货舱类似注释第12-8页飞行员操作手册原始版本：，2002年第12小节氧气系统Hawker 800XP Pro Line 21第三节-系统描述飞行机组供气面罩调节器在正常飞行条件下，面罩调节器选择为-N“位置。在该设置下，氧气与空气的比率随着海拔高度的增加而增加，直到大约30000英尺处，当提供100%氧气时。在35000至41000英尺之间，100%氧气在正压下自动保持。然而，当面罩调节器选择到100%位置时，在任何海拔高度都可以获得100%氧气。将面罩调节器旋钮转到紧急情况在正压下提供100%氧气供应。通过将选择器设置到100%位置并将调节器旋钮推到测试位置，可以对调节器进行功能测试。氧气的流动可以通过感觉来检查；测试可以在面罩存放的情况下进行。图6氧气面罩和调节器（型号25A025A）飞行员操作手册第12-9页修订版A1：2002年11月第12小节氧气系统Hawker 800XP Pro Line 21第三节-系统描述护目镜为机组人员提供了组合式烟雾护目镜和面罩调节器，护目镜存放在飞行舱左侧和右侧控制台中。注意：戴上氧气面罩前，必须摘下耳机和帽子。客舱内的两个自密封出口提供治疗用氧气。
A contents indicator is mounted next to the charging valve. The charging supply passes through a line filter and bursting disc assembly before joining the pipeline from the cylinders to the automatic shut-off valve. The automatic shut-off valve is also located in the oxygen box assembly and is provided to shut off the oxygen supply should there be a rupture of the supply pipeline downstream of the valve. All system piping is made from stainless steel or light alloy, except for hoses which connect the oxygen cylinders, drop-out mask units, therapeutic outlets, and the mask quick-release sockets. Figure 3 Oxygen Box Assembly Page 12-6 Pilot’s Operating Manual Original Issue: Feb, 2002 Sub-section 12 OXYGEN SYSTEM Hawker 800XP Pro Line 21 Section III - SYSTEMS DESCRIPTION OPERATION Oxygen from the storage cylinders is fed to the master SUPPLY valve on the flight compartment oxygen panel on the left console. Opening the master SUPPLY valve allows oxygen to flow to the contents indicator and the pressure regulator, then, at 70 psi to the combined mask-regulators, therapeutic outlets and the baromatic valve.

The cylinder rests in a fixture secured to the rear of the flight compartment right console. Pre-Mod. 252939: The top of the cylinder is secured to the forward face of panel DA by a toggle fastener. Post-Mod. 252939: The cylinder is secured by a toggle fastener, and hinged bracket which covers electrical power points on panel DA. 2nd FLASHLIGHT Figure 5 Portable Oxygen Smoke Set OXYGEN CYLINDER HINGED OXYGEN CYLINDER MOUNTING PANEL PANEL DA FORWARD MASK STOWAGE GOGGLE STOWAGE ON LEFT SIDE SIMILAR NOTE Page 12-8 Pilot’s Operating Manual Original Issue: Feb, 2002 Sub-section 12 OXYGEN SYSTEM Hawker 800XP Pro Line 21 Section III - SYSTEMS DESCRIPTION FLIGHT CREW SUPPLY Mask-Regulator Under normal flight conditions the mask-regulator is selected to the —N“ position. At this setting the ratio of oxygen to air increases with an increase in altitude until at approximately 30,000 feet, when 100% oxygen is supplied. Between 35,000 and 41,000 feet 100% oxygen at a positive pressure is automatically maintained. However, 100% oxygen is available at any altitude when the mask regulator is selected to the 100% position. Turning the mask regulator knob to EMERGENCY provides a 100% oxygen supply under positive pressure. The regulator can be functionally tested by setting the selector to the 100% position and pushing the regulator knob to TEST position. The flow of oxygen can be checked by feel; the test can be carried out with the mask in its stowage. Figure 6 Oxygen Mask and Regulator (Mod.

NOTE: Headsets and hats must be removed before donning oxygen masks. THERAPEUTIC SUPPLY Oxygen for therapeutic use is available at two self-sealing outlets in the passenger cabin.
