摘要
某发动机批生产中多次出现滑油消耗量大故障,其故障率较高,严重影响了发动机正常生产与交付。为了解决这一问题,对该机滑油系统结构原理特点进行了分析,找出影响滑油消耗量的主要因素,并通过对滑油系统(供、回油系统、空气密封系统)各参数的大量统计分析、计算、试验研究,找出其对滑油消耗量的影响及相互关系,制定出滑油消耗量大故障排故措施,并在生产中应用,取得了良好效果。
This thesis studies on the lubrication consumption overrun malfunction of an aero-engine in batch production leading the negative influences. The lubricating system structure and theory are analyzed to clarify the factors of lubrication consumption overrun malfunction. The statistics, calculations and experiments on the lubricating system are conducted to confirm the influences on the malfunction and relations between the various factors. Accordingly, the measures are proposed to eliminate the malfunction with excellent effects in application.
