如何控制液压油的高温与污染

国内各大中型矿山使用的液压挖掘机均采用液压油作为工作介质,造成液压系统故障的70%-85%原因是由于系统的污染,而系统污染的35%原因是由油液高温引起的。因此控制系统高温,可以控制系统污染,而控制系统污染,可以极大的降低液压系统的故障率。我从多年对液压挖掘机系统维保的角度,对液压油高温给系统带来的危害做简单论述。

The domestic large and medium-sized mining using hydraulic excavator adopts hydraulic oil as working medium, 70%-85% of the hydraulic system failure is due to contamination of the system, the system is 35%of the reason is caused by the oil temperature. So high temperature control system, can control system of pollution, and pollution control system, can greatly reduce the failure rate of the hydraulic system. I from the Angle of the years of the hydraulic excavator system maintenance, the harm of hydraulic oil temperature to simple.
