摘要
以流量信号作为特征信息进行液压故障诊断，分析了液压系统中出现流量异常时的主要表现及产生原因，基于流量信号与液压系统工况之间关系的分析及 ＣＢＧ ２０４０型齿轮泵的 ４种故障的实验研究，指出：流量信号也是状态信息的丰富载体，利用流量信号来监测液压系统的状态及进行故障诊断是可行的、有效的．
The reason why unusual flow signals exist and the main effect of the siguals were investigated in hydraulic systems. It is pointed out that flow signals are also a rich carrier of condition information after the examination of the close relationship between the work condition of hydraulic systems and the flow nals. According to the experimental research on the faults of gear pump, it is practicable and effective using flow signals to monitor the condition of hydraulic systems and to diagnose the faults.
