Whether the paper machine equipment is running normally, its key components play a very important role. The press roll is one of the more important parts in the paper machine. If there is a failure, it must be repaired in time to avoid delaying production.
During the operation of the equipment, the press roll of the paper machine is constantly scoured by the material, and wear problems often occur in the transmission parts. Usually, the bearing parts of the press roll are worn. If it is not treated, the equipment will continue to wear and tear, which will cause damage to our equipment, thereby affecting the normal operation of our equipment.
When the paper machine press roll is worn, the more traditional repair methods are surfacing, thermal spraying, electroplating, etc., but there are disadvantages in different places. During repair welding, there is no way to completely eliminate thermal stress due to high temperature, and the electroplating layer will also be limited to a certain extent. If we want to solve this problem, we must use polymer composite materials to solve it. Since the material itself has good adhesion and compressive strength, it can be repaired on site without disassembly, which saves time and manpower compared to traditional methods. Moreover, our polymer material has the concessional property of lack of metal, which can well absorb the shock and vibration caused by the operation of the press roll, reducing the probability of secondary wear.
The reasons for the failure of the press roll and the solutions are summarized for everyone. I hope everyone will pay attention to it when using it, so as to ensure that our paper machine runs more smoothly.
