Common Paper Machine Equipment Failure
Common paper machine equipment failures are as follows:
- Abrasion. The reasons for wear mainly include parts and equipment that have long contact with copper mesh, pulp, wool cloth or moulding paper, such as pulper, pulp pump, vacuum box panel, sand cleaner, calendering roller, pressing roller, etc. Another reason is the frequent movement between parts, such as steam inlet, vacuum roller, scraper, cylinder and vacuum pump.
- Lubrication. The mechanical rotation is directly related to the bearing. The paper machine mainly made of rotating rolls. There are many types and quantities of rollers, and there are hundreds of bearings of various types in paper machine. Therefore, the management of lubrication is very necessary. Especially affected by water, heavy load and high temperature, the lubricating oil is prone to evaporation, loss and aging. This can cause damage to the lubrication effect, resulting in bearing damage and shaft head wear problems. Therefore, the regular inspection of the oiling work is extremely necessary.
- Machine Fatigue. Heavy duty and continuous operation are easy to cause fatigue damage to machinery. Because some parts are restricted by the mechanical structure and operating principle on paper machine. So the parts cannot have too much design strength to avoid damage. It can be solved by using measures such as maintenance techniques.
