机床液压系统的滤油器一般安装在吸油管路入口处,且全浸泡在油箱的液压油内,它是液压油的清洁工。能将液压油中的污物过滤干净,以提高液压系统的可靠性,保持系统正常工作,延长设备使用寿命。笔者在实际维修中深有体会,在使用中的液压设备,凡是运动部件突然产生爬行和系统压力不足现象,85％以上均属系统滤油器堵塞故障而造成。但是,在维修现场,人们往往都按有关资料介绍,仅从油泵进空气、油缸活塞皮碗击穿、阀类元件失灵、运动部件机械卡死等因素找原因,而忽视了被称为液压系统重要辅助元件——滤油器。 1 诊断诊断滤油器是否有堵塞故障,方法很简单,拆除滤油器,起动油泵电动机,让油泵直接吸油,视压力表指针显示工作压力后,操纵运动部件控制手柄(或按钮),部件能正常动作,且压力指示平稳,则表明滤油器存在堵塞故障。否则表明滤油器正常。
The hydraulic system of the machine oil filter is generally installed in the suction pipe inlet, and all immersed in the tank of hydraulic oil, it is hydraulic oil cleaners. Can filter the dirt in the hydraulic oil clean, in order to improve the reliability of the hydraulic system, maintain the normal operation of the system and prolong the service life of the equipment. The author in the actual maintenance of deep experience in the use of hydraulic equipment, all moving parts suddenly produce creeping and system pressure shortage phenomenon, more than 85% are caused by the system filter plugging failure. However, at the maintenance site, people often according to the relevant information, only from the pump into the air, piston cylinder piston breakdown, valve failure, moving parts and mechanical factors such as death find the reason, while ignoring the so-called hydraulic system Important auxiliary components - oil filter. 1 DIAGNOSIS DIAGNOSIS Whether or not the oil filter is clogged is very simple. Remove the oil filter, start the oil pump motor, let the oil pump directly absorb the oil, and control the moving part control handle (or button) as the pressure gauge pointer shows the working pressure. Normal operation, and pressure indicating a smooth, then there is a clogged filter failure. Otherwise it shows that the oil filter is normal.
