Where can the wear and tear of the paper machine be more serious?

    What are the reasons for the wear of the paper machine? The complete set of equipment that makes the pulp form the division of the paper web is collectively called the paper machine, including 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 and heat recovery.

    1. Lubrication: Mechanical rotation is inseparable from bearings. In paper machines with rotating rolls as the mainstay, there are many types and numbers of rolls. There are hundreds of bearings of various types. Therefore, lubrication management is very important, especially when 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 load and continuous operation 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 suction cup, 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: Reason one, parts and equipment that have been in contact with copper mesh, felt, pulp, or forming paper for a long time, such as pulp pumps, pulpers, desanders, vacuum box panels, press rolls, calender rolls, etc.; The second reason is the relatively frequent movement of parts, such as the scraper of the paper machine, the steam head, the air cylinder, the vacuum roll, and the vacuum pump.
