u.lube team on-site service case: bearing lubrication improvement solution for dairy longitudinal sealing machine
the plastic packaging line of the dairy factory uses a longitudinal sealing machine to seal the packaging bag for cold drink finished product.but after on-site research, our u.lube team found there’s some existing problems as followed:
1、 设备工况涉及高温，轴承处温度 130℃左右，出现润滑脂高温流失严重现象，目前使用某牌普通锂基润滑脂在 90-100℃左右就流失；
1、the equipment working condition involves high temperature, the temperature at the bearing is about 130℃, there is a serious loss of grease at 90-100℃ when using a brand of ordinary lithium grease.
2. the longitudinal sealing machine basically keeps running 24 hours, the bearing fatigue is high, in many cases it runs without oil, which results more serious wear on bearing, therefore, it brings frequent replacement of bearing.
3. at the same time, the grease is manually added, which increases human cost, poor greasing results and oil-free running.
4. in the workshop water vapor environment, the current grease’s waterproof performance is relatively poor, easy lead to lubrication failure.
纵封机润滑改良 longitudinal sealing machine lubrication improvement
针对上述润滑问题，优润(u.lube)团队建议进行润滑改良，需要选择一款合适的轴承润滑脂如优润(u.lube)高性能合成润滑脂 et plex 72s， 具有良好的高温耐受性与低温适用性。工作温度范围宽(-40℃～180℃)，润滑寿命长。产品由特制复合锂稠化剂及全合成基础油制作而成，具有良好的耐温、耐化学稳定性、滴点高、抗磨性能好，并且具有良好的抗氧化能力及防锈能力，保障产品在高温、水及水蒸汽环境下均能保持良好的工作状态，满足以下几点要求。
for the above lubrication problems, the u.lube team recommends a suitable bearing grease such as u.lube high performance synthetic grease et plex 72s, which has excellent high temperature resistance and low temperature applicability. it has a wide operating temperature range (-40°c to 180°c) and long lubrication life. the product is made of special complex lithium thickener and full synthetic base oil, which has good temperature resistance, chemical stability, high dropping point, good anti-wear performance, good anti-oxidation ability and anti-rust ability, and ensures good working condition under high temperature, water and vapor environment. it also meets following requirements:
1. use grease with high temperature resistance up to 160℃, the working temperature of longitudinal sealing machine bearing is between 130-140℃, the grease’s working temperature should be 20-30℃ above the maximum temperature point.
2、 要满足纵封机24小时工作状态，则应该使用耐高剪切力，四球载荷 200kg 以上具有良好润滑性，减缓轴承疲劳的工作状态，延长轴承使用寿命；
2. in order to meet the 24-hour working condition of the longitudinal sealing machine, grease with high shear force should be used, and its four ball load is more than 200kg with good lubrication, which can slow down bearing fatigue and extend the service life of bearings.
3. using a long-lasting lubricant to keep good oil film and lubrication of the bearing can change the situation of frequent refueling, save labor cost and improve efficiency.
4、for the workshop water vapor environment, it requires the lubricant must have good water resistance and waterproof performance to ensure the bearings can keep working normally for 24 hours under the humid environment in the workshop.
