辊压机轴承润滑，需要什么样润滑脂？优润特种润滑给出答案
What kind of lubricant is best for roller press bearing? U.LUBE Special Lubricants give the answer!
辊压机轴承负载高、压力大，存在低速冲击载荷，且工作环境多有粉尘污染，因此要求主轴承润滑脂能够形成较高强度的润滑油膜以抵抗冲击载荷影响。同时，需要润滑脂泵送性能好，工作温度范围宽，以保障在低温环境下也能在润滑系统泵送下提供有效润滑。
The working condition of roller press bearing is heavy load, high pressure, low-speed shock load , and dust pollution, so it requires the main bearing grease can form a high strength lubricating film to resist the impact load. At the same time, a grease with good pumpability and wide working temperature range can provide effective lubrication even under low temperature environment.
从技术角度上来说，普通极压锂基脂的基础油粘度一般无法达到1000~1500 cSt(@40℃)，极压性能四球焊接载荷一般无法达到400kg，根据国标GB/T 6391关于辊压机轴承寿命的影响因素中的建议，辊压机主轴承润滑脂需达到以上性能为佳。
From the technical point of view, the base oil viscosity of common extreme pressure lithium grease generally cannot reach 1000~1500 cSt (@40℃), and its four ball welding load generally cannot reach 400kg. According to the recommendation in standard GB/T 6391 on influencing factors of roller press bearing life, it’s better to choose a grease which can reach the above properties for roller press main bearing.
市面上现有辊压机主轴承润滑剂满足以上条件，如优润重载轴承脂ET RP 1500系列润滑脂，得到鹏飞等设备厂家OEM推荐，广泛应用于水泥、矿山、钢铁、电力、化工、造纸等行业的大型设备的轴承润滑，如:辊压机、干燥机、造粒机、挖掘机、破碎机等，具有良好的润滑性能，包括高滴点、泵送性好、良好的抗氧化性能、高粘附性能、显著的防腐性能、长效、抗重载抗振动冲击性能良好，能够减少设备磨损，延长设备使用寿命。同样，也适用于低速、有冲击、振动载荷的设备润滑。
The existing roller press main bearing lubricants on the market meet the above conditions, such as U.LUBE heavy-duty bearing grease ET RP 1500 series, which has gotten the recommendation from OEM equipment manufacturers such as PENG FEI, and is widely used in the bearing lubrication of large equipment in cement, mining, steel, electric power, chemical and paper industries, such as: roller press, dryer, granulator, excavator, crusher, etc. It has good lubricating performance, including high drip point, good pumping properties, good anti-oxidation properties, high adhesion properties, significant anti-corrosion properties, long-lasting, good anti-vibration and shock resistance to heavy loads, can reduce equipment wear, extend the service life of equipment. Likewise, it is also suitable for lubrication of equipment with low speed, shock and vibration loads.
辊压机工作环境多有粉尘污染，不加防护，有效润滑将大打折扣，如配合防护型润滑系统(VMAXX辊压机防护型润滑系统)，对润滑脂要求需要泵送性能好，而优润ET RP 1500能满足在低温环境下也能被泵送提供给辊压机轴承有效润滑，达到良好的润滑效果，保障企业生产线正常运转。
Roller presses work in an environment with dust pollution, if without protection, lubrication effect will be greatly reduced. Grease requirements good pumping properties when use with the protective lubrication system (VMAXX roller press protective lubrication system) , here we recommend the U.LUBE ET RP 1500 grease which can be easily pumped and provide effective lubrication to roller press bearings even under low temperature, to achieve good lubrication effect and ensure the normal operation of the enterprise production lines.
