coal chemical mill open gear lubrication improved, tooth surface temperature decreased
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.
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.
