Frequently Asked Questions Related to the Press Section of Paper Machinery-Jinling Paper Machine

　　Common problems related to the press section of papermaking machinery. Vibration is a common problem in the press section. In severe cases, it will produce marks on the paper web, causing the paper machine to slow down or stop. Unbalanced press rolls and bearing problems are the most obvious causes of vibration. Uneven press felt or roll coating, frame vibration, and vibration transmitted from other equipment components or scraper frames are all potential sources of vibration. Many press rolls are medium and high rolls, and their nip pressure is not optimized, and the pressure in some press sections is uneven. The uneven distribution of pressure in the transverse direction of the paper machine will result in uneven moisture in the banner of the press felt. The holes or longitudinal folds of the press felt not only damage the felt and interfere with production, but also damage the rollers. The most common problems related to the running performance of the paper machine are that the paper web breaks during the open threading after the press, the paper web is excessively stuck to the press roll, the paper web is crushed in a nip, and the wet streaks in the paper can pass Cancel the open threading, select the appropriate press roll material, use the appropriate nip pressure and press felt to overcome these problems.
