The Main Reasons For The Vibration Of The Paper Press Roller

The main reasons for the vibration of the paper press roller are as follows:;

1. The squeezing roller has not found a good balance;

2. Natural frequency vibrations generated at specific vehicle speeds;

3. Due to improper storage, use, or long-term shutdown without lifting, the squeezing roller surface is not round;

4. The press roller bearings are damaged and not replaced in a timely manner;

5. The squeezing roller is not rotating smoothly, and there are problems with the electrical control; The pressure of the hydraulic squeezing and pressurization device is abnormal;

6. There are soft spots on the hanging rubber roller, and there are pulp blocks sticking to the surface of the pressing roller;

7. The uneven layering of papermaking blankets, uneven plugs, and fabric induced vibrations can be alleviated by changing the fabric moisture content, pressing load, and paper machine speed.
