Trouble analysis and solution of paper machine press roll

In view of the phenomenon of paper machine roller wear, the more traditional repair methods include surfacing, thermal spraying, electroplating, etc., but they all have the shortcomings of different parts. When repairing and welding, because the temperature is too high, thermal stress will be generated, and there is no way to completely eliminate it, and the electroplating layer will also be subject to certain restrictions. To solve this problem, it is necessary to choose polymer composite materials to solve it. Because the material itself has good adhesion and compressive strength, it can be repaired on site without disassembly, saving more time and manpower than traditional methods. Moreover, our polymer materials have the compatibility of metal defects, which can well absorb the shock and vibration caused by the operation of the press roller, and reduce the probability of secondary wear.

The key components of paper machine equipment play a very important role in the normal operation of the equipment. The pressure roller is one of the important parts in the paper machine. If there is a failure, it should be repaired in time to avoid delays in production.

During the operation of the equipment, the pressure roller of the paper machine is constantly being washed by the material, and the transmission part often suffers from abrasion problems. The bearing part of the pressure roller is usually severely worn. If it is not processed, the equipment has worn out, which will cause damage to our equipment, which will affect the normal operation of our equipment.
