BOPP横拉风机轴承润滑改良方案，优润(U.LUBE)团队现场服务

U.LUBE team on-site service: Lubrication improvement solution for bearing of BOPP transverse stretching machine

某石化公司BOPP车间共有40套横拉风机，其中轴承润滑使用的是某牌中高速轴承脂，目前陆续出现问题，有两台已出现淅油现象（如下图轴承下方的油槽）。

A petrochemical company has 40 sets of BOPP transverse stretching machines, among which a brand of medium and high-speed bearing grease is used on bearings. Currently, 2 machines appeared oil separation problem (the oil tank below the bearing in the photo below).

经咨询优润(U.LUBE)团队后，优润(U.LUBE)团队赶赴现场进行现场调研，检测横拉风机轴承的润滑状态，通过热成像仪、振动仪等工具拿到设备的温度值、振动值等数据和现场的照片。

After the on-site research, our U.LUBE team has checked the status of bearings and got the temperature value, vibration value and other data of the equipment and photos of the site through thermal imager, vibration meter and other tools.

经检测，目前横拉风机轴承温度控制可以，在规定的温度范围内工作；但是轴承的振动值比较大，尤其是垂直和水平的振动值超过5，是比较危险的，应该划到停机检修的范围内。

After inspection, the bearing temperature of BOPP transverse stretching machine can work within the specified temperature range; however, the bearing vibration value is relatively large, especially the vertical and horizontal vibration value is more than 5, which is dangerous and should be classified to shutdown maintenance.

另外、轴承座密封存在一定问题，淅出的油甚至少量油脂会从密封处挤出（如下图）。

Moreover, there are certain problems on the bearing seat sealing, the oil and even a small amount of grease will be extruded from the sealing parts (as following photo).

根据现场的现象和检测数据分析淅油原因，优润(U.LUBE)团队判断本身目前车间使用的某牌中高速轴承脂性能较差，经过设备较大振动，对油品的剪切力加大，更容易产生淅油现象，而且轴承座密封又一般，导致淅油较多。

According to the analysis of the phenomenon and testing data, U.LUBE team judged that the performance of a brand of medium and high speed bearing grease used in the workshop was poor, and the shearing force of the oil increased after the larger vibration of the equipment, which made it easier to separate the grease, and the sealing of the bearing seat is not good enough and easy resulting in more grease separation.

经优润(U.LUBE)团队建议，针对目前BOPP横拉风机轴承润滑状况，目前采用以下措施：

According to the suggestions of U.LUBE team, the following measures should be adopted for the current lubrication condition of the bearing of BOPP transverse stretching machine:

1、 及时改善设备振动过大问题，减少振动就减少了对油品的剪切力，就减小了淅油的可能性；

Improve the equipment vibration problems, reducing vibration can reduce the shear force , therefore it can result less oil separation.

2、 改善密封现状，及时更换密封件，在密封件上涂抹一圈密封脂，增强密封性能；

Improve the sealing through replacing the sealing parts, and applying a ring of sealing grease to enhance the sealing performance.

3、 使用稠度更大密封性更好的轴承润滑脂，如优润(U.LUBE)润滑脂ET FLUOR 72 ，适用于电机轴承，熔炉轮轴承，烘干设备轴承，定型机轴承，酸、碱性物质，汽油、燃油、溶剂等操作与泵送等应用于，适用于各种极限温度与苛刻工况下，需要长效润滑与密封的部位。

Use bearing grease with greater consistency and better sealing performance, such as U.LUBE grease ET FLUOR 72, which is suitable for motor bearings, furnace wheel bearings, drying equipment bearings, shaping machine bearings, equipment under acid, alkaline substances, gasoline, fuel oil, solvents on operations and pumping applications, and parts under a variety of extreme temperatures and harsh working conditions, with long-lasting lubrication and sealing.
