摘要
本文结合篦齿封严装置的结构特点、基于已知的发动机转子卡滞问题,分析梳理了篦齿封严装置异常刮磨引起发动机转子卡滞的原因,并说明了篦齿封严装置刮磨引起的转子卡滞是多因素耦合作用的结果、且具有一定的偶发性.
Abstract
Based on the structural characteristics of the grate sealing device and the known problem of engine rotor binding,the cause of abnormal scraping and grinding of the grate sealing device causing engine rotor binding is analyzed.It is illustrated that the rotor binding caused by the scraping of the grate sealing device is the result of the coupling effect of multiple factors.It has a certain degree of randomness.
