摘　　要：介绍了注塑机的液压控制原理和动作过程,利用故障树分析法,通过逐层分析及故障之间的逻辑关系,对注塑机的系统故障进行了诊断。实践证明,应用故障树分析法对注塑机等复杂设备进行故障诊断,其速度快、效率高,并可以用来预测和诊断故障、指导设备的正常运行和预防性维保。The hydraulic control principle and movement process of the injection molding machine were introduced. The Fault Tree Analysis （FTA）method was used to diagnose system failure of the injection molding machine,through analyzing layer by layer and logical relationship between the faults. Practice has proved that FTA method can efficiently and rapidly diagnose faults of the injec-tion molding machine and other complex equipment. Moreover FTA can be used to forecast and diagnose faults,guide normal running and preventive maintenance of equipment.
