摘要
大型工程机械功能逐渐增多,液压系统的复杂程度增加,液压系统故障定位排除的难度加大。将逻辑表达式引入到液压系统的故障诊断中,可以大幅度缩小故障检测的范围,实现故障的快速定位,提高故障排除的效率。该方法在复杂液压系统的故障诊断中有较大的使用价值。
More and more functions in large-scale construction equipment and the increasingly complicated hydraulic system result in more difficulty in trouble positioning and removal of the hydraulic system.The logic expression is introduced to the failure diagnosis of the hydraulic system,which can effectively narrow the range of trouble detection,rapidly position the trouble and improve efficiency of trouble removal.The method is provided with great use value for trouble diagnosis in complex hydraulic system.
