摘　　要：针对某型涡喷航空发动机使用中滑油压力摆动故障进行分析和研究,通过对发动机进行分解检查,找到引起滑油压力摆动的故障点,从而采取在发动机制造过程中严格控制焊接质量、修理时对焊缝着色探伤检查不允许有裂纹、装配前及工厂试车后对轴承机匣内腔进行气密试验检查等措施进行控制,提高发动机制造、修理质量,保证发动机的安全使用。In this paper,the fault of lubricating oil pressure swing in the use of a turbojet engine is analyzed and studied.Through engine decomposition inspection,the fault point causing lubricating oil pressure swing is found,so as to take measures(namely,strictly controlling the welding quality during the engine manufacturing process,conducting dye penetrant inspection of welds during repairs without cracks,and conducting air tightness testing on the inner cavity of the bearing gearbox before assembly and after factory testing) to control it,improve the quality of engine manufacturing and repair,and ensure the safe use of the engine.
