In order to overcome the shortcoming of complicated structure for electrical and pneumatic central lubrication system of mining hydraulic excavators, the hydraulic central lubricant system was designed. By fully using the hydraulic system of the mining hydraulic excavators, the hydraulic oil was used as power supply for the designed system to drive the hydraulic grease pump and supply grease for all the lubrication points. A single-line injector was used for the designed system,which simplified the hydraulic central lubricant system and made all the lubrication points to get a good lubrication.为了克服矿用液压挖掘机电动和气动集中润滑系统存在系统复杂的缺点，设计液动集中润滑系统。该系统充分利用矿用液压挖掘机的液压系统，以液压油为动力源驱动液动润滑泵，向各个润滑点供脂，同时采用单线给油器，简化了整个集中润滑系统，使各个润滑点得到良好的润滑。
