Coal chemical mill open gear lubrication improved, tooth surface temperature decreased


某煤化工厂的气化车间现有四台由江阴中立机械生产的Φ4.0x6.0m磨机。开式齿轮采用喷雾润滑方式。经优润(U.LUBE)团队现场检查,发现磨机齿面存在不同程度的损伤,润滑效果不佳,如不及时解决,严重时将影响整个企业生产。

There are four Φ4.0x6.0m mills produced by Jiangyin Neutral Machinery in the gasification plant of a coal chemical plant. The open gears are lubricated by spray system. After an on-site inspection by the U.LUBE team, it was found that the mill tooth surfaces had different degrees of damage and the lubrication effect was poor, which would affect the production of the whole enterprise in a serious situation if not solved in time.


为了改善润滑,控制开式齿轮进一步磨损,延长磨机的使用寿命,优润(U.LUBE)团队以多年专业润滑经验,根据现场调研情况结合实际工况,推荐逐步使用符合开式齿轮润滑规范的产品的高性能开式齿轮润滑剂如优润ET G-OG C-16M。经过近一年的观察,从齿面温度、设备振动、齿面润滑状态及设备运行情况来看,优润高性能开式齿轮操作润滑剂达到了预期的使用效果。

In order to improve lubrication, control further wear of the open gear and extend the service life of the mill, U.LUBE team, with many years of professional lubrication experience, recommended the gradual use of high performance open gear lubricants such as U.LUBE ETG-OG C-16M, which is in line with the open gear lubrication specification, based on the site research and actual working conditions. After nearly one year of observation, from the point of view of tooth surface temperature, equipment vibration, tooth surface lubrication status and equipment operation, U.LUBE’s high performance open gear operating lubricant has achieved the expected use effect.


换油前,齿面较干,石墨碾压的面积较大,痕迹较深。换油后,油品粘度高,油膜厚,油膜承载能力较强,油品对齿面的润滑减摩效果更佳。相比之前,齿面石墨碾压的面积明显较少,齿面润滑效果有明显的改善。从齿面热成像数据对比分析,齿面温度有所下降,但齿面端部仍存在一定程度的载荷集中,对应区域热量累积较多,齿面接触较重,需持续关注,优润(U.LUBE)团队也会保持定期调研跟踪情况。

Before the oil change, the tooth surface is dry, the area of graphite lapping is larger and the trace is deeper. After the oil change, the oil viscosity is high, the oil film is thick, the oil film bearing capacity is stronger, and the oil has better lubrication and friction reduction effect on the tooth surface. Compared with before data, the area of tooth surface graphite lapping is obviously less, and the tooth surface lubrication effect is obviously improved. From the tooth surface thermal imaging data comparison analysis, the tooth surface temperature has decreased, but the tooth surface end still has a certain degree of load concentration, the corresponding area of heat accumulation more, the tooth surface contact is heavier, need to continue to pay attention to, U.LUBE team will also maintain regular research tracking situation.
