大型数控机床液压系统串流故障的诊断与排除
|
摘要
针对大型数控机床液压系统常见串流故障的诊断问题,提出了机床液压系统现场维修的基本原则,以捷克HD200WD镗铣床为例,重点介绍了其主轴箱液压系统串流故障的分析和排除过程,并且提出了一种针对截止式三位四通电磁阀的创新检测工装和方法,检测效率高、准确性好。
Aiming at the diagnosis of common series flow faults in hydraulic system of large numerical control machine tool,the basic principle of field maintenance of hydraulic system of machine tool is put forward. Taking Czech HD200WD boring and milling machine as an example,this paper mainly introduces the analysis and elimination process of the series flow faults in the headstock hydraulic system,and puts forward an innovative testing tool and method for the cut-off three-position four-way solenoid valve,which has high detection efficiency and good accuracy.
