发动机引气系统是保证飞机空调、增压、大翼防冰、液压等系统安全可靠工作 的前提。引气系统低压是发动机引气系统的常见故障,但在有些情况下,按照常规的排故方法并 不能找出低压故障的原因。根据引气系统原理图进行故障分析,可以缩小故障范围,分析故障原 因,是解决引气系统疑难故障最有效的方法。
Engine air bleed system is to ensure that the aircraft air-conditioning, turbocharger, big wing anti-ice, hydraulic system, safe and reliable work of the premise. Low bleed air bleed is a common failure of the engine’s bleed air system, but in some cases it is not possible to find the cause of a low pressure bleed according to a conventional troubleshooting method. Fault analysis based on the bleed air system schematic diagram can narrow the fault range and analyze the cause of the fault, which is the most effective way to solve the difficult fault of the bleed air system.
