某型飞机发动机在试车时,起动过程一切正常,进入平衡转速(100%)后,燃油压力、燃油耗量、扭矩等仪表指示参数都摆动,且长时间不能稳定工作。参数摆动故障的发生,无疑对正常的飞行训练造成较大的影响。一、常见故障及原因1.粗细油滤脏粗油滤和细油滤用来过滤燃油中的机械杂质,当燃油中有水时也可以沉淀水。由于发动机燃油条机器只有7-10的运动间隙,所以燃油
When a certain type of aircraft engine is in test run, the starting process is all normal. After entering the balancing speed (100%), the instrumentation parameters such as fuel pressure, fuel consumption, torque and the like all swing and can not work stably for a long time. The occurrence of parameter swing failure undoubtedly has a great impact on normal flight training. First, the common failures and causes 1. Crude oil filter coarse oil filter and fine oil filter used to filter the mechanical impurities in fuel, when the fuel in the water can also precipitate water. Because the engine fuel rod machine only 7-10 movement gap, so fuel
