Title (EN) METHOD AND APPARATUS FOR PUMPING LARGE SOLID ARTICLES
(FR) PROCEDE ET APPAREILLAGE POUR LE POMPAGE D"ARTICLES SOLIDES DE GRANDES DIMENSIONS
Abstract: front page image
(EN)A pump for pumping large solid articles includes a rotary pump having a plain disc impeller (28) disposed in a substantially cylindrical chamber (26) of a housing (24) with an inlet (54) coaxial of the impeller into the housing and an outlet (56) from the periphery of the chamber with a rotor arranged to provide a substantially unobstructed passage between the inlet past the discs of the rotor to the outlet of the pump. The impeller includes pairs of discs (40, 42) spaced close together for providing increased fluid pressure and pairs spaced apart of distance for providing a passage for the solid articles. The articles are pumped in a fluid medium, such as water, through the pump and maintained suspended during transport from the inlet to the outlet of the system.
(FR)Cette pompe comprend une pompe rotative ayant un impulseur a disque simple (28) place dans une chambre substantiellement cylindrique (26) d"un bati (24) avec une admission (54) dans le bati coaxiale a l"impulseur et une sortie (56) de la peripherie de la chambre dont le rotor est agence pour fournir un passage substantiellement non obstrue entre l"admission, les disques du rotor et l"orifice de decharge de la pompe. L"impulseur comprend des paires de disques (40, 42) a espacement faible provoquant une augmentation de la pression du fluide et des paires espacees plus largement pour permettre le passage des articles solides. Ces articles sont pompes dans un milieu fluide, au travers de la pompe et sont maintenus en suspension pendant le transport depuis l"orifice d"admission jusqu"a l"orifice de decharge du systeme.
