据了解,很多矿井满负荷运行的国产大型提升机,在夏季高温季节都程度不同地存在着减速器润滑油过热、滑动轴承超温的问题。例如,我矿主井JKM-3.25×4型提升机,近几年随着矿井原煤产量的逐年增加,提升机连续运转的时间延长,轴承超温问题日渐突出,经常影响生产。该减速器采用润滑油站强迫润滑的方式进行润滑。据此特点,我们自制了一台水冷式油冷却器,串 It is understood that many large-scale operation of the mine at home large hoist, varying degrees in the summer high temperature season exist over-temperature gear lubricants, bearing over-temperature problem. For example, mine mine shaft JKM-3.25 × 4 hoist, in recent years with the mine coal production increased year by year, hoist continuous operation of the extension of the bearing temperature problems have become increasingly prominent, and often affect the production. The reducer using lubrication station forced lubrication lubrication. According to this feature, we made a water-cooled oil cooler, string
