Do you know the main reasons for the wear of the impeller in a three-lobe rotary blower?
Release time:
2022-06-14
There are many reasons for wear, so wear is very complex. But what are the reasons for the wear of the three-lobe Roots blower impeller? 1. Fatigue wear = surface fatigue stress (or temperature or impact) leads to surface cracks and flaking. 2. Abrasive wear = due to the filing effect of solid particles dispersed between interfaces under relative motion and wear, resulting in concave surfaces and uneven contact surfaces. It has a significant impact on the degree of wear of the impeller. In the three-lobe Roots blower, solid particles and the surface of parts move relative to each other at a relatively fast speed, causing wear. 3. Erosion wear = surface scratches formed by solid particles cleaning the metal surface. 4. Adsorption wear = if other conditions are the same, improving processing accuracy and surface cleanliness does not reduce wear. On the contrary, because the interface is tight, the molecular adsorption function is large, and interface wear increases. This is adsorption wear.
