1. Wear: First, Parts And Equipment That Have Been In Contact With Copper Mesh, Woolen Cloth Or Paper Pulp And Formed Paper For A Long Time, Such As Pulp Pump, Pulper, Desander, Vacuum Box Panel, Press Roll, Calender Roll, Etc; The Second Reason Is That Parts With Relatively Frequent Movement Between Parts, Such As Scrapers, Steam Inlet Heads, Cylinders, Vacuum Couch Rolls, Vacuum Pumps, Etc.

2. Lubrication: Mechanical Rotation Can Not Be Separated From Bearings. For Paper Machines, Mainly With Rotating Rollers, There Are Many Types And Quantities Of Rollers, And There Are Hundreds Of Bearings Of Various Models. Therefore, Lubrication Management Is Very Important, Especially Under The Influence Of Water, High Temperature And Heavy Load. Lubricating Oil (grease) Is Easy To Run Off, Evaporate And Age, Thus Damaging The Lubrication Effect, Causing Bearing Damage And Shaft Head Wear. Therefore, It Is Essential To Check And Refuel Regularly.

3. Fatigue: Heavy Loaded And Continuously Running Machinery Is Prone To Fatigue Damage. On Paper Machine, Due To The Restriction Of Mechanical Structure And Operation Principle On Some Parts, The Design Strength Of Parts (such As Mesh Table Shaking Spring Plate, Electromagnetic Clutch Suction Cup, Coupling Anti Overload Pin, Etc.) Should Not Be Too Large To Avoid Damage. Measures Such As Maintenance And Technical Transformation Can Be Taken To Solve The Problem.
