解决水泥厂辊压机高温报警，优润(u.lube)辊压机脂保障生产运转
solve the high temperature alarm problem of roller press in cement plant, u.lube roller press grease ensure the production operation
某水泥厂的辊压机是合肥院产的hfcg160-140，其对辊轴承润滑原使用某牌润滑剂，加油方式则采用电动泵加油，分配器为电磁给油器形式。
the roller press of a cement plant is hfcg160-140 made by hefei institute, which uses a brand of lubricant for roller bearing lubrication, and adopts electric pump for refueling, and use the electromagnetic oil feeder in distributor.
先前辊压机频繁出现设备高温报警，经优润(u.lube)团队到现场调研，发现主要是使用的润滑剂无法满足辊压机对辊轴承的润滑要求，导致轴承略有磨损，温度升高进而报警。
previously, the roller press had frequent high temperature alarms, and the u.lube team went to the site to investigate and found that the main reason was that the lubricant used could not meet the lubrication requirements of the roller bearing of the roller press, which led to bearing slightly wear, and the temperature increased and then alarmed.
辊压机的对辊轴承润滑需要专用的重负载高性能润滑脂，如优润(u.lube)辊压机轴承脂et rp 1500，能够适应高负载、高温工况下的设备运转，具备抗水性好、抗冲击载荷，具有良好的润滑性能，能够最大程度地减少设备磨损，延长设备使用寿命。
the roller bearing lubrication of roller press needs special heavy duty high performance grease, such as u.lube roller press bearing grease et rp 1500, which can adapt to the operation of equipment under high load and high temperature conditions, with good water resistance, impact load resistance and good lubrication performance, which can minimize equipment wear and extend equipment life.
通过与现场人员进行沟通交流及现场调研，解决轴承高温问题以及降本考虑，优润(u.lube)团队建议水泥厂更换使用专用辊压机轴承脂。
through communication with site personnel and on-site research, the u.lube team recommended the cement plant to replace the roller press bearing grease with a special roller press bearing grease to solve the high temperature problem and reduce costs.
使用优润(u.lube)辊压机脂前后热成像仪测温对比
comparison of temperature measurement by thermal imager before and after using u.lube roller press grease
在换油前后外界环境温度无太大差异，冷却水冷却情况良好，入料温度均衡，工作压力及电流稳定一致等情况下，使用优润(u.lube)辊压机脂前后热成像仪测温对比：辊压机轴承温度存在一定程度降低。
before and after the oil change, there was no big difference in the external environment temperature, the cooling water was good, the feeding temperature was balanced, and the working pressure and current were stable and consistent, etc. the temperature of the roller press bearings decreased to a certain extent by the thermal imager before and after the use of u.lube grease.
在换油前，辊压机轴承温度最高47.6℃，设备高温报警，轴承出现磨损以及维护工作量大，换油后，辊压机后非驱动侧动辊轴承温度存在一定程度下降，同时四个轴承温度保持在合理温度范围内，温度最高40℃，对辊轴承温度、工作压力都保持正常，未出现高温报警/跳停等异常现象。表明轴承润滑情况良好，保证辊压机长期稳定运行，减少大量维护工作。
before the oil change, the bearing temperature of the roller press was 47.6℃ at the highest, the equipment high temperature alarm, bearing wear and maintenance workload, after the oil change, the temperature of the dynamic roller bearing on the rear non-driven side of the roller press decreased to a certain extent, while the temperature of the four bearings remained within a reasonable temperature range, the temperature was 40℃ at the highest, the temperature and working pressure of the roller bearing remained normal, and no abnormal phenomena such as high temperature alarm/jump stop occurred. it shows that the bearing lubrication is good, which ensures the long-term stable operation of the roller press and reduces a lot of maintenance work.
