摘　　要：某型飞机上使用冷气操纵系统的部件比较多,是该机型比较重要的工作系统。在冷气供压部分中,冷气减压器的常见故障为出口压力不稳、漏气和不减压等;吸潮器的有机玻璃外壳经常出现裂纹和掉块现象。结合冷气减压器和吸潮器的构造原理,对其故障原因进行分析,并提出了相应的修理方案以及维护策略,期望对海军飞机同类附件的修理和维护提供借鉴。There are many accessories which are important working systems in the compressed air control system of the aircraft. For the pressure supply part, the fault probability of the pressure reducer and air breather is high. The frequent fault of the pressure reducer is the air leaking, unstable pressure of the export and unreduced pressure output. The plexi- glass shell of the air breather often cracks. Even some dollops of the shell scale off. Based on the structure characters of these two accessories, the fault mechanism is investigated. Also, the corresponding repair and daily maintenance methods are given, providing reference for repairing and maintenance of the similar air accessories.
