Analysis and Solution of the Failure of the Press Roll of Paper Machine. Whether a piece of equipment is operating 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 and handled in time to avoid delays in production.
During the operation of the equipment, the press roll of the paper machine is constantly scoured by the material, and there is often a problem of wear in the transmission part. Usually, the bearing part of the press roll is worn out. If it is not treated, the equipment will wear out all the time, which will cause damage to our equipment, which will affect the normal operation of our equipment.
In view of the phenomenon of wear of the press roll, the more traditional repair methods are surfacing welding, thermal spraying, electroplating, etc., but they all have the disadvantages of remote locations. When repairing welding, due to the high temperature will produce thermal stress, there is no way to completely eliminate it, and the electroplating layer will also be subject to certain restrictions. If we want to solve this problem, we have to choose polymer composite materials to solve it. Since the material itself has relatively 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 materials have the lack of metal concessions, which can well absorb the shock and vibration caused by the operation of the press roll, reducing the probability of secondary wear.
