四柱液压机液压系统故障诊断

四柱液压机广泛适用于可塑性材料的压制工艺。如粉末制品成型、塑料制品成型、冷(热)挤压金属成型、薄板拉伸以及横压、弯压、翻透、校正等工艺。但液压系统优缺点突出,造成液压系统故障有诸多因素,且液压系统是在绝对封闭状况下运行,损坏与失效经常发生在内部,故障点隐蔽、原因复杂、部位不易确定。因此,熟悉了解四柱液压机液压系统常见故障及采用快速、正确判断故障部位的方法,对于液压系统故障的迅速诊断及维修尤为重要。本文通过分析液压机液压系统常见故障,提出了液压系统故障诊断方法,具有一定借鉴意义。

Fault diagnosis of hydraulic system of four-column hydraulic press

Four-column hydraulic press is extensively applicable to pressing techniques of plastic materials,such as forming of powder products,forming of plastic products,forming of cold(hot)extrusion metals,and extension,horizontal press,bending,correction of thin plates.However,the hydraulic system also has outstanding disadvantages.Many factors may lead to faults of hydraulic system,and hydraulic system runs under fully enclosed condition,so damages and failures often occur inside the system.Moreover,the position ...
