The impeller is the "heart" is the most important parts of slurry pump, the hydraulic performance of pump performance mainly depends on the impeller. The failure of live pump is mainly because the flow of serious wear and scrap, the impeller wear failure is the most common, the service life is short. The wear failure analysis, failure analysis is very important, as long as the correct, can really find the causes of wear fire effect, so the wear problems often can smoothly done or easily solved.
Erosion is a kind of wear form which is destroyed by the surface of the small and loose particles in the village. Particle in general small 1mm, impact velocity in the 55Om/s, beyond the range of material damage, often belong to the study of erosion wear.
Hard particles or on the grinding surface of the micro convex body in the friction caused by the material damage caused by the fire called abrasive wear. Because it has no or less lubrication and adhesion problem, it is relatively a simple form of wear. The material in the slurry pump, the two is its failure to wear.
