1 Abrasive wear
In the fan, the solid particles move relative to the surface of the parts at a certain speed, which will cause abrasive wear. Concave and uneven contact surfaces, wear due to the filing effect under relative motion or the abrasive action of solid particles dispersed between the interfaces. It has a great influence on the degree of impeller wear.
2 Adsorption wear
When other conditions are the same, even if the machining accuracy level and cleanliness of the machined surface are improved to make them fit better, the wear will not be reduced. Instead, because the interface is close, the molecular adsorption is significant, which aggravates the wear of the interface. Adsorption wear.
3 Scour wear
Surface abrasion caused by the erosion of solid particles on the metal surface is called erosion wear.
4 Fatigue wear
Fatigue wear is caused by surface cracks or scales falling off due to surface fatigue stress (or temperature or impact).
