综掘机液压系统的泄漏及预防

Dirulge and Prevent of Comprehensive Mechanized Driving Hydraulic System

掘进机液压系统的泄漏主要原因有:油液污染、密封表面粗糙度不当、密封沟槽不合格,管接头松动、配合件间隙增大、油温过高、密封圈变质或装配不良等。在使用与修理过程中应强化防漏治漏的修理工艺。

Machinery of grub hydraulic pressure systemic leak mostly cause have：oil pollute,airproof surface granulation unsuitable,airproof groove disqualification,cannulation tie-in become flexible,cooperate clearance.Augment,exorbitant oil temperature,airproof workpiece metamorphose or assemblage badness and otherwise.At use and repair course,we must aggrandizement repair technics.To keep from happening of leak and father leak.
