U.LUBEteamon-siteservicecase:Bearinglubricationimprovementforhotfanofpaperplant
某纸厂目前共有热风机10台，由于温度高每天加油比较不方便，以及油脂损耗大。经优润(U.LUBE)团队现场调研发现，热风机轴承为SKF轴承，轴径分别为：内径75，外径，转速转/分钟。使用测温枪测轴承座温度为-℃，在工作不太正常的情况下轴承座温度会升到℃左右，据此推算，轴承的实际温度正常情况下应该在-℃，目前使用的油脂为某牌的油脂，基本上每天都需补加油脂，从现场看，环境中灰尘较多，油脂出现流失等现象。

润滑改良建议Suggestionsforlubricationimprovement
针对上述问题，优润(U.LUBE)团队建议使用合适的润滑剂对轴承进行润滑，如优润(U.LUBE)高温轴承润滑剂，同时也要定期检查轴承密封性，避免密封件老化等。优润(U.LUBE)高温轴承润滑剂在满足热风机轴承高温持续运转的基础上，提高了油品的抗磨承载能力，润滑改良后可以降低轴承的磨损率，延长轴承的使用寿命，增强轴承密封性，改善油脂流失，提高设备运行的稳定性，减少设备维护成本。

针对热风机每天都需人工补加油脂的情况，优润(U.LUBE)团队建议使用VMAXX单点加脂器，提高生产效率。另外，在更换合适的润滑剂之后，对热风机的运转状态应进行状态监测和故障诊断，通过对设备的温度监测、振动分析、油液检测等各种先进的检测手段，掌握设备运行状态，判定产生故障的部位和原因并预测、预报设备未来的状态。从而防止设备事故和计划外停机，提高设备的维护水平。
