我矿使用的4m~3挖掘机,共有润滑点96个,原来用油壶手动注油和涂沫润滑,铜套磨损较快,个别的挖掘机仅使用1年左右,铜套磨损量最大达5～6mm。 1982年我们在4m~3挖掘机上应用了干油自动集中润滑,经过5年来的使用,效果良好,润滑可靠,延长了备件的使用寿命。自动集中润滑系统主要由风动干油泵、单线给油器、管道及电控盘等组成,由人工控制按钮起动,停止,其运转由挖掘机本身的空气压缩机为动力,带动风马达驱动柱塞式干油泵工作。 I mine used 4m ~ 3 excavator, a total of 96 lubrication points, the original manual oiled and painted with oil lubrication, copper sleeve wear faster, individual excavators only use about 1 year, the wear of copper up to 5 ~ 6mm. In 1982 we applied 4m ~ 3 excavator automatic concentrated oil lubrication, after 5 years of use, the effect is good, reliable lubrication, extending the life of spare parts. The automatic centralized lubrication system is mainly composed of a pneumatic dry pump, a single-line oil feeder, a pipe and an electric control panel, and is started and stopped by a manual control button. The operation of the automatic centralized lubrication system is driven by the air compressor of the excavator itself and drives the wind motor driving column Plug dry pump work.
