铜山矿是一个已投产30年的老矿,全矿设备新度系数为0.38(1989年),选矿新度系数仅有0.15。通过对设备现场技术管理和一系列改善维修,降低了备件库存和消耗,1989年备件消耗为28.3元/千元产值。备件库存周转天数为189天,连续10年处于同行业领先地位,并保持了设备技术性能良好,安全经济运行。主要做法如下。1.加强润滑管理,确保防尘密封装置有效,严格润滑“五定”,多年未发生润滑事故,滚动轴承使用寿命均在10年以上,齿轮等主要传动件寿命达30年。
Tongshan Mine is an old mine that has been in operation for 30 years. The new coefficient of the whole mine equipment is 0.38 (1989), and the new coefficient of beneficiation is only 0.15. Through the on-site technical management of the equipment and a series of improvements and repairs, spare parts inventory and consumption were reduced. In 1989, the spare parts consumption was 28.3 yuan / thousand yuan. Spare parts inventory turnover days of 189 days, for 10 consecutive years in the same industry-leading position, and maintained a good technical performance of equipment, safe and economical operation. The main approach is as follows. 1. To strengthen lubrication management, to ensure effective dust seal, strict lubrication “five”, for many years without lubrication accidents, rolling bearing life are more than 10 years, the main gear and other life expectancy of 30 years.
