After long-term use, the wood chip machine will have the symptoms of wear and tear. With the appearance of this phenomenon, the damage to the equipment will be greater. If it is not resolved and dealt with in time, once the wear degree reaches a certain level, it may Will directly cause the equipment to malfunction, which will affect the progress of use. For this series of problems, let ’s first understand the types of wear and tear. Let ’s take a look at them together with Xiaobian!
1. Particle abrasion: Hard particles or raised materials cause the material to fall off during the friction process, which will slightly affect the equipment.
2. Equipment surface abrasion: Surface abrasion is a common condition of wood chip machines. At the same time, alternating contact stress causes primary micro-cracks on the surface, and the phenomenon of material particles falling off continues to develop. For example, small rolling spots or acne-like pits often appear on the rolling element surfaces of equipment rolling bearings, near the gear tooth surface indexing circle, and the contact surfaces of the rails and wheels. This is the typical surface fatigue and wear.
3. Corrosion and abrasion: When the surface is in a corrosive environment, reaction products will be generated on the surface of the chip machine. The reaction products have a weak ability to bind to the surface. They will generally be worn away under constant friction, and the exposed ones will quickly generate new The reactants were cycled through this. Impact on equipment.
