Introduction to the Main Causes of Abrasion of Three blade Roots Blower Impeller

Introduction to the main reasons for wear of three blade roots blower impeller. There are many reasons for wear, so the wear is very complicated. But what is the reason for wear of three blade roots blower impeller?

1. Fatigue wear=appearance fatigue stress (or temperature or impact) causes appearance crack and scale falling off.

2. Abrasive wear=because of the file effect of solid particles dispersed between interfaces under the action of relative motion and wear, concave and uneven contact surfaces are generated. It has a greater impact on the wear of the impeller. In the three blade roots blower, the solid particles and the surface of the parts move at a relatively fast speed, resulting in wear.

3. Scour wear=surface scratches formed by solid particles cleaning the metal surface.

4. Adsorption wear=if other conditions are the same, improving machining accuracy and surface cleanliness will not reduce wear. On the contrary, because the interface is tight and the molecular adsorption function is large, the interface is worn and added. This is adsorption wear.
