我铁矿现有5台1987年购置的工作质量为460t的WK-10A型电动正铲挖掘机,随着生产任务的逐年增加,为了使其发挥出最大的生产能力,减少挖掘、回转、行走机构摩擦部位的磨损,延长挖掘机使用寿命,我们决定对其润滑脂加注方式进行改进。1.存在缺陷及改进方法(1)存在缺陷WK-10A型挖掘机主要由挖掘、回转和行走机构组成。其中挖掘机构的推压装置有10个注油点,
At present, the iron mine has 5 sets of WK-10A electric front shovel excavators with a working mass of 460t purchased in 1987. With the increasing production tasks, in order to maximize its production capacity and reduce excavation, slewing and walking Friction parts of the body wear and prolong the service life of excavators, we decided to improve its grease filling method. 1. Defects and methods of improvement (1) Defects WK-10A excavator mainly consists of digging, turning and walking mechanism. Excavating mechanism which has 10 push points oiling device,
