| 摘 要： | 液压泵是液压系统的动力源,它的失效直接影响着系统的正常工作,因此液压泵的状态监测与故障诊断是迫切需要解决的问题。作者以YB16型叶片泵为研究对象,将传统的求振动信号功率谱法与先进的专家系统技术相结合,使对泵的故障诊断更为准确。本文所介绍的方法可推广到其它类型液压泵的故障诊断中去,还可对长期运行而重要的液压系统中的动力源进行在线监测。

| Abstract: | The failure of hydraulic pump as a power unit in hydraulic systems affects directly the proper performance of the systems.Therefore,the monitoring of the pump performance and diagnosis of pump faults are urgent problems in want of solution.With vane pump YB16 as the authors' object of study, they combine the conventional method of finding the power spectrum with the advanced expert system which makes the diagnosis even more accurate.The method introduced here can be applied to fault di- agnosis of other types of hydraulic pumps,as well as to the on-line monitoring of important hydraulic power units for long-term service. |
