Title (EN) SUBMERGED PUMP DEVICE AND METHOD
(FR) DISPOSITIF DE POMPE IMMERGÉE ET PROCÉDÉ ASSOCIÉ
Abstract:
(EN) A piston-pump device (1) for use underwater is described, in which a pump shaft (5), via a cylinder housing (9) which is axially fixedly mounted on the pump shaft (5), is arranged to move a number of pistons (20) between a first position and a second position in respective cylinder bores (12), and each of the pistons (20) is connected to a piston shoe (22) which is securely held in a slanted track of rotation, the track of rotation of the piston shoes (22) and of a sliding ring (25) being arranged between a supporting ring (26) and a slip surface (28) on a bevelled plate (27). A method of adapting a piston pump (1) for use underwater is described as well.
(FR) La présente invention se rapporte à un dispositif de pompe à piston (1) destiné à être utilisé sous l'eau et pour lequel un arbre de pompe (5), par l'intermédiaire d'un logement de cylindre (9) qui est monté axialement et fixement sur l'arbre de pompe (5), est agencé pour déplacer un certain nombre de pistons (20) entre une première position et une seconde position dans des alésages de cylindre respectifs (12), et chaque piston (20) est raccordé à un sabot de piston (22) qui est tenu de manière sûre dans une trajectoire de rotation inclinée, la trajectoire de rotation des sabots de piston (22) et d'une bague coulissante (25) étant agencée entre une bague de support (26) et une surface glissante (28) sur une plaque biseautée (27). La présente invention se rapporte également à un procédé permettant d'adapter une pompe à piston (1) destinée à être utilisée sous l'eau.
