Abstract

Un involucro o corpo per una pompa ad anello liquido, ottenuto per fusione in materiali metallici, comprende una bocca d'aspirazione assiale (2) raccordata ad una camera premente anulare (5) atta ad accogliere una girante periferica (11) e provvista di una bocca di mandata (6). La bocca di aspirazione (2) presenta, nella zona di raccordo con la camera premente (5), un canale periferico approssimativamente radiale (10) ed un'apertura passante assiale (20), entrambi ottenuti mediante un'unica anima di fusione formante sia la bocca (2) che la camera (5). L'apertura (20) è provvista di un bordo anulare (21) che definisce una superficie di rasamento frontale (22) per la girante. Tale bordo (21) definisce con la parete opposta della girante (11) un elemento di separazione tra la bocca d'aspirazione (2) e la camera premente (5).A casing or body for a liquid ring pump, obtained by casting in metallic materials, includes an axial suction mouth (2) connected to an annular pressing chamber (5) adapted to receive a peripheral impeller (11) and provided with a delivery port (6). The suction mouth (2) has, in the connection area with the pressing chamber (5), an approximately radial peripheral channel (10) and an axial through opening (20), both obtained by means of a single fusion core forming both the mouth (2) and the chamber (5). The opening (20) is provided with an annular edge (21) which defines a front leveling surface (22) for the impeller. This edge (21) defines with the opposite wall of the impeller (11) a separation element between the suction mouth (2) and the pressing chamber (5).
