Title (EN) COMBINED JACKET EJECTOR AND CENTRE EJECTOR PUMP
(FR) EJECTEUR À CHEMISE ET POMPE À ÉJECTION CENTRALE COMBINÉS
Abstract:
(EN) It is described an ejector pump (1) arranged for pumping a fluid containing particles or aquatic organisms, where the ejector pump ( 1) comprises: - a primary pipe (2) for directing a flow of a first motive fluid from a nozzle (22) on a free end portion (21) of the primary pipe (2) in a direction of a longitudinal axis (69) of an outlet pipe (6); - at least one inlet tube (3) for a pumped fluid; - a pump house (4); - a jacket (5) surrounding the pump house (4); - an outlet pipe (6) downstream of the pump house (4) comprising a mixing zone (60); and - an annular nozzle (52) around the pump house (4) for directing a flow of a second motive fluid in the direction of the longitudinal axis (69) of the outlet pipe (6)f the annular nozzle (52) is in fluid communication with the jacket (5), and where a longitudinal axis (39) of the at least one inlet tube (3) has a sloped angle (33) between 5 and 35 degrees relative to the longitudinal axis (69) of the outlet pipe (6).
(FR) L'invention concerne une pompe (1) à jet agencée en vue de pomper un fluide contenant des particules ou des organismes aquatiques, la pompe (1) à jet comportant: - une conduite primaire (2) servant à diriger un écoulement d'un premier fluide moteur issu d'une buse (22) sur un partie (21) d'extrémité libre de la conduite primaire (2) dans la direction d'un axe longitudinal (69) d'une conduite (6) de sortie; - au moins un tube (3) d'entrée destiné à un fluide pompé; - une enceinte (4) de pompe; - une chemise (5) entourant l'enceinte (4) de pompe; - une conduite (6) de sortie en aval de l'enceinte (4) de pompe comportant une zone (60) de mélange; et - une buse annulaire (52) autour de l'enceinte (4) de pompe servant à diriger un écoulement d'un deuxième fluide moteur dans la direction de l'axe longitudinal (69) de la conduite (6) de sortie; la buse annulaire (52) étant en communication fluidique avec la chemise (5), et un axe longitudinal (39) du ou des tubes (3) d'entrée présentant un angle (33) de pente compris entre 5 et 35 degrés par rapport à l'axe longitudinal (69) de la conduite (6) de sortie.
