案例|铜矿厂中信球磨机开式齿轮润滑改良，优润团队现场服务
某铜矿厂的φ4.5ｘ7.6m球磨机，为中信重工生产，在2013年开始投产，球磨机开式齿轮原使用某牌润滑油进行操作润滑，喷洒系统为某牌润滑系统，采用六个喷嘴进行喷洒。齿面润滑情况不稳定，非驱动端接触比较重，大小齿对应部位油膜比较薄，呈现石墨碾压痕迹，废油堆积，同时润滑剂消耗量比较高。
the φ4.5x7.6m ball mill of a copper mining plant, produced by citic heavy industries, was put into operation from 2013. the ball mill open gear previously used a brand of lubricant for operation and lubrication, and the spraying system was a brand of lubrication system with six nozzles for spraying. the lubrication performance of tooth surface is unstable, the contact of non-drive end is relatively heavy, the oil film of the match part between gear and pinion is thin, presenting graphite lapping traces and oil residue accumulation, meanwhile the lubricant consumption is relatively huge.
经优润团队现场调研分析，再与业主方沟通，确定以能够改善开齿齿面损伤情况，增强设备保护并减少油脂消耗量的云顶集团官方网站入口的解决方案，建议使用优润et系列高性能纯油，有良好的粘附性能及优良的抗磨、抗极压性能，特别适用载荷高，有冲击的开式齿轮传动机构。
after the on-site research and analysis by our u.lube team, and then communicate with client, we made a solution that can improve the damage of open gear surface, enhanced the protection of equipment and reduce the consumption of grease, and suggested to use u.lube et series high performance pure oil, which has good adhesion with excellent anti-wear and anti-pressure performance, especially for the open gear transmission mechanism with heavy load and impact.
从3月开始，使用优润et o-og c-f16纯油，球磨机整体齿面润滑情况较好，油膜较厚，非驱动端接触较重部位相对换油之前石墨碾压面积减少，油膜变化明显；
our client began to use the product: u.lube et o-og c-f16 from march, the overall tooth surface lubrication of the ball mill is highly improved, the oil film is thicker, graphite lapping area of heavier contact part of the non-drive end is relatively reduced compared with the lubricant used before, and the performance of oil film is highly improved.
在5月、6月时，优润团队又进行两次检查，球磨机整体润滑情况较好，油膜较厚且透亮，大小齿轮面可见明显的金属光泽，齿面光滑平整，无明显损伤，废油堆积因纯油流动性改善而得到解决，有效的改善废油的排放和废油的处理等问题，降低现场维护工作和难度。
in may and june, our u.lube team also carried out two inspections, we found that the overall lubrication performance of the ball mill was better, the oil film was thick and translucent, the size of the gear surface was visible with obvious metallic luster, the tooth surface was smooth and flat without obvious damage, the oil residue accumulation was solved by the improvement of pure oil fluidity, effectively improving the discharge and disposal of waste oil, therefore, greatly reduced the difficulty of on-site maintenance work.
同时，整体润滑剂使用量有所下降。原使用某牌润滑剂消耗量为50kg/40天左右；更换使用优润纯油之后，润滑剂消耗量为50kg/60天左右，综合对比润滑剂用量较之前能节省大约1/3左右，为业主方降本增效。
at the same time, the overall lubricant usage has been reduced. the consumption of the lubricant previously used is about 50kg per 40 days; after replacing the u.lube lubricant, the consumption reduced to 50kg per 60 days, which can save about 1/3 compared with the previous lubricant and reduce the cost and increase the efficiency for client.
▲使用优润纯油后，球磨机大小齿齿面光滑平整，无明显损伤
▲after using u.lube pure oil, the tooth surface of the gear and pinion of the ball mill is smooth and flat without obvious damage.
