摘　　要：挖掘机在日常作业过程中,由于机手操作不当使整机长期处于溢流、超温等不良工况,导致泵的剩余使用寿命受到影响,缩短了液压泵的使用周期。针对此类问题,文章提出一种全电控挖机液压泵健康状态评价方法。通过筛选各种可以影响泵使用寿命的性能指标,对液压泵剩余使用寿命进行综合评估,并最终以打分的形式展示,根据液压泵的打分情况来对泵的剩余寿命进行评估。当健康得分较低时,及时提醒用户进行液压泵故障检查或维修更换。In the daily operation process of excavator,due to the improper operation of the machine,the whole machine is in bad working conditions such as overflow and overtemperature for a long time,which affects the remaining service life of the pump and shortens the service life of the hydraulic pump.In order to solve these problems,this paper presents a method of health evaluation of hydraulic pump of full electronic control excavator.By screening various performance indicators that can affect the service life of the pump,the remaining service life of the hydraulic pump is comprehensively evaluated,and finally displayed in the form of scoring,and the remaining life of the pump is evaluated according to the scoring situation of the hydraulic pump.When the health score is low,timely remind the user to check the hydraulic pump fault or repair and replace.
