Where will the wear of paper machine be more serious?

What are the reasons for the wear and tear of the paper machine? The complete set of equipment that makes the pulp form the divisional linkage of the paper web is collectively called the paper machine, which includes the headbox, the wire section, the press section, the drying section, the calender, the reeling machine, and the transmission section. The main engine and auxiliary systems such as steam, water, vacuum, lubrication, heat recovery, etc.

1. Lubrication: The mechanical rotation is inseparable from the bearing. The paper machine mainly rotates the roll. There are many types and numbers of rolls. There are hundreds of various types of bearings. Therefore, lubrication management is very important, especially when it is exposed to water, high temperature, Under the influence of heavy load, lubricating oil (grease) is easy to lose, evaporate, and age, which will damage the lubrication effect and cause bearing damage and shaft head wear. Therefore, regular inspection and refueling is essential.

 2. Fatigue: Heavy-duty and continuous-running machinery are prone to fatigue damage. On the paper machine, because some parts are restricted by the mechanical structure and operating principle, the design strength of the parts (such as the screen shaking spring plate, electromagnetic clutch sucker, coupling anti-overload pin, etc.) should not be too large to avoid damage. As a solution, measures such as maintenance and technical transformation can be taken.

3. Wear and tear of the paper machine: Reason one, the parts and equipment that have been in contact with copper mesh, wool cloth or pulp and forming paper for a long time, such as pulp pump, pulper, desander, vacuum box panel, press roll, calender roll Etc.; Reason two, relatively frequently moving parts between parts, such as the scraper of the paper machine, the steam head, the air cylinder, the vacuum roll, the vacuum pump, etc.
