Bearing is the paper easily-worn part and once wear failure, must stop and replace, it will give the mill produce certain economic loss. So guarantee bearing a continuous and reliable operation, the normal running of paper machine has important significance. In the paper the most easy to wear usually high speed of the failure of part is the paper nets bearing, squeezing department bearing, pressure light machine especially super pressure light machine and soft light pressure machine bearing, the reason is the parts of the machine working very bad, overwhelmed, high temperature, high humidity and high-speed operation. And at present paper machine the usual lubricant abrasion resistance, water resistance insufficient, it can't reach "ideal lubrication", even if is to use some of the world famous brand of synthetic lubricants also cannot completely meet and deal with the paper machine of the bad conditions.

Based on the sensing technology, control the development of technology and continuous production requirement, the modern high speed machine maintenance system by the time has been gradually into the state of TBM maintenance CBM change, the current domestic paper machine using lubricant lubrication performance insufficient,so it is because of bad lubrication lead to bearing failure caused the paper machine scheduling downtime is not unavoidable, and will be more.

Usually, once appear abnormal temperature increase paper bearing, vibration increase exceeds the situation, it needs to stop changing bearing. This paper introduces a kind of method of on-line repairing bearing.

The method of on-line repairing paper machine bearing

In the paper machine using common lubricant appear abnormal temperature rise, bearing vibration increase overweight need to stop changing bearing, can through the higher performance lubricant for on-line repairing bearing. When stop in not into high-performance lubricant, the replacement of the original lubricant, run after period of time, may also play a role of repair, bearing temperature and vibration return to normal and can make paper machine maintain run to overhaul, and thoroughly clean and replace the lubricant and don't have to replace bearing. At present, there are already has the repair function of the high performance lubricant. If the United States purple crown company produces the purple crown synthetic lubricants. On-line repairing the paper machine failure can not only reduce the bearing scheduling downtime, avoid to cause huge economic losses, but also can save large amount of the cost of maintenance and bearing equipment spending.
