Etude de l'effet de cavitation sur les roues de différents types de matériaux des pompes de POVAL.

Abstract

Indeed, work that planned us to carry out in this memory proposes to study the phenomenon of cavitation in the radial centrifugal pumps. With this intention, we took the pump (40 NVA) as an example in the first time; a general theoretical study has inculs the various characteristics of the pump, and the phenomenon of cavitation in addition, and at the time of the practical part, we tried to apply this phenomenon on the pump (200 hours for each type of materials in fact, bronze, aluminum and cast iron). This experiment will be based primarily on these three types of metals which are used in the manufacturing of wheel. And this for the study of resistibility of each material.
