Abstract

La présente invention se rapporte à des pompes durables pour liquides abrasifs. Selon une mise en uvre, une pompe centrifuge donnée à titre d'exemple ou un étage de pompe pour une opération de sous-surface comprend une rondelle de butée placée à l'intérieur de la circonférence d'un joint d'étanchéité bien ajusté avec jeu entre un flasque de roue et le diffuseur. La nouvelle disposition de la rondelle de butée permet au joint d'étanchéité avec jeu de protéger la rondelle de butée des liquides abrasifs pendant que la rondelle de butée supporte la roue contre les forces de réaction du flux liquide axial. Selon une mise en uvre, le rayon ou la taille d'une rondelle de butée ou d'un autre élément caractéristique semblable à un joint d'étanchéité est réduit, ou réduite, afin d'augmenter l'exposition du flasque de roue inférieur au fluide mis sous pression, ce qui permet d'équilibrer la pression au niveau de la partie supérieure et de la partie inférieure de la roue afin de diminuer le frottement entre la roue et la rondelle de butée. La réduction du rayon de la rondelle de butée permet également de réduire la surface de la rondelle soumise à un frottement et de réduire le bras de levier d'un couple de freinage sur la roue rotative, ce qui permet de réduire la perte de puissance de la pompe.
