针对某型航空发动机在实验准备时和实际应用中,多次出现压气机前轴承封严圈、压气机后轴承封严圈及后封严盒的石墨涂层磨损和剥落现象,封严能力下降的现象,导致发动机滑油消耗量大等故障进行了分析,并进行了机械结构优化设计,总结出优化设计的要点,加工出优化调整后的产品,并将新产品装于现有设备进行了有效验证。
Aiming at the aero-engine experimental preparation and practical application, the wear-and-tear phenomenon of the graphite coating of the front seal ring of the compressor, the seal ring of the rear bearing of the compressor and the back seal box appeared many times, The phenomenon that led to the engine lubricating oil consumption is analyzed, and the mechanical structure optimization design is summarized, the key points of the optimization design are summarized, the optimized and adjusted products are processed, and the new products are loaded into the existing equipment Validated
