Definitions

  • the object of the present invention is a simplified modular system for manufacturing centrifugal pumps, which due to its configuration, provides a greater sturdiness of the pump assembly while preventing vibrations and offsetting.
  • the blind nut placed on the end of the wheel shaft has an inner pressure washer and an O-ring for sealing the shaft, while in the industrial application it has a standard washer.
  • the present invention relates to a simplified modular system for manufacturing centrifugal pumps constituted by a body-flange (1) joined to the casing of a motor (12) and which allows passage of the shaft (13) of the open wheel (4) in sanitary application pumps and the semi-open wheel (5) in industrial application pumps, and also Includes the part Intended for the pump impulsion (14).
  • the seal of the body-flange (1) and the cover (2) is achieved by an O-ring (8), located on the peripheral seat (1.1) of the body-flange (1).
  • the body-flange (1) has an inner seat (1.2) on which rests a cover-closure (3) that allows to couple different types of mechanical closures between this cover-closure (3) and the wheel (4, 5).
  • the cover-closure system (3) comprises two parts (29,30). The outer part (29) is coupled by screws (31) to the body of the pump (1), and the inner part (30) iscoupled to the mechanical closure, the two joined to each other by screws (32).
  • the cover-closure (3) is also provided with a centering office (33).
  • the body-flange (1) and the cover (2) are joined by screws (7) while the blind nut (9) preferably Includes a standard washer (18).

Claims (10)

  1. Une pompe centrifuge comprenant un joint torique assurant l'étanchéité entre les parties en contact avec le fluide à pomper (8), dotée d'un corps de pompe composé d'un premier élément, une bride de corps (1), reliée à un corps de moteur (12), le corps de pompe permettant le passage de l'axe (13) d'une roue (4, 5) et comprenant une partie servant au refoulement de la pompe (14) et un deuxième élément (2) auquel la bride d'aspiration de la pompe (15) a été soudée, caractérisée en ce que la bride de corps (1) présente une portée intérieure (1.2) dans laquelle une fermeture couvercle (3) une a été placée, la couverture couvercle comprends deux parties (29, 30), une partie extérieure (29) montée sur le corps de la pompe (1) à l'aide de vis (31), et une partie intérieure (30), montée sur une fermeture mécanique, les deux parties de ladite couverture couvercle étant reliées au moyen de vis (32).
  2. Une pompe centrifuge selon la revendication 1, caractérisée en ce que la bride de corps (1) et la couverture (2) sont reliées par un collier (6) lorsque le mécanisme est appliqué à une pompe de plomberie.
  3. Une pompe centrifuge selon la revendication 2, caractérisée en ce que le collier (6) est constitué de deux parties reliées par des extrémités rainurées (19) et dont l'une des extrémités est raccordée de façon permanente à un anneau (20) retenu par une broche (21); à l'autre extrémité se trouve une partie (22), également retenue par une broche (21), qui épouse et qui est incorporée dans les extrémités rainurées (19), et qui est dotée d'un logement (23) servant à l'insertion d'une vis (24) destinée à serrer le collier (6).
  4. Une pompe centrifuge selon la revendication 1, caractérisée en ce que la bride de corps (1) et la couverture (2) sont reliées au moyen de vis (7) lorsque le mécanisme est appliqué à une pompe de plomberie.
  5. Une pompe centrifuge selon la revendication 1, caractérisée en ce qu'un écrou à chapeau (9) a été incorporé dans l'extrémité de l'axe (13) de la roue (4), comprenant de préférence une laveuse à pression intérieure (16) ainsi qu'un joint torique (17) destiner à garantir l'étanchéité de l'axe (13) lorsque le mécanisme est appliqué à une pompe de plomberie.
  6. Une pompe centrifuge selon la revendication 1, caractérisée en ce qu'un écrou à chapeau (9) a été incorporé dans l'extrémité de l'axe (13) de la roue (5), comprenant de préférence une laveuse traditionnelle (18) lorsque le mécanisme est appliqué à une pompe de plomberie.
  7. Une pompe centrifuge selon la revendication 1, caractérisée en ce qu'un joint torique (10) a été placé entre le corps de moteur (12) et la bride de corps (1) afin d'empêcher que du liquide de nettoyage ne pénètre à l'intérieur du moteur, lorsque le mécanisme est appliqué à une pompe de plomberie.
  8. Une pompe centrifuge selon la revendication 1, caractérisée en ce que la roue (4) est ouverte dans le cas des pompes utilisées dans le domaine de la plomberie.
  9. Une pompe centrifuge selon la revendication 1, caractérisée en ce que la roue (4) est semi-ouverte dans le cas des pompes utilisées dans le domaine industriel.
  10. Une pompe centrifuge selon la revendication 1, caractérisée en ce que la fermeture couvercle (3) est dotée d'une fonction de centrage.
