With the rapid development of industrial automation technology, the hydraulic system technology and computer control technology of paper machine have also developed rapidly, and the working performance and automation level of paper machine have made great progress. The development direction of paper machine is towards larger volume, higher production efficiency and faster paper output speed.
The working performance of the paper machine depends on the working state of the press section. The main function of the press section of the paper machine is to use mechanical extrusion to generate huge linear pressure on the couch roll to discharge the water content of the low wet paper web, so as to improve the dryness when the paper web enters the drying section of the paper machine. Especially during pressing, the online pressure of the couch roll has a great impact on the pressing and dehydration, When the paper machine is working, the linear pressure of the press is continuously increased, and the dehydration capacity of the press will be significantly improved.
