目前我国共有Ty—154飞机40多架。其中,西北航空公司有10架。自1985年使用至今,这10架飞机发生液力系统污染故障达26次之多。其污染源来自液力系统的机械泵。—89的磨损使之大量的金属沫进入系统。而泵的磨损主要是液力系统的液压油初始污染所致。在日常工作中大家对流体污染造成机械部件损伤的认识了解甚少,下面我就对这一问题以及如何防止流体污染的发生作一论述。
At present, there are more than 40 Ty-154 aircraft in China. Among them, Northwest Airlines has 10 aircraft. Since its use in 1985, up to 26 hydraulic system contamination failures have occurred on these 10 aircraft. Its source of pollution comes from the hydraulic system of mechanical pumps. The wear of -89 caused a large amount of metal foam to enter the system. The wear and tear of the pump is mainly due to the hydraulic system of hydraulic oil caused by the initial pollution. In our daily work, there is little understanding of the damage caused by fluid pollution caused by mechanical parts. Here I will discuss this issue and how to prevent fluid pollution.
