Title
(EN) UNDERWATER PUMP
(FR) POMPE IMMERGÉE
(JA) 水中ポンプ
Abstract
(EN) This underwater pump (100) is provided with a one-sided water channel (6) extending along a rotary shaft (1) on one side of an underwater pump main body (100a), the underwater pump (100) comprising: an impeller (4); and a pump casing (5) in which the impeller (4) is disposed on the inner side thereof, wherein the pump casing (5), as seen from the axial direction of the rotary shaft (1), includes a tongue part (53) disposed between a pump chamber (5a) in which the impeller (4) is disposed and an inlet opening (6a) of the one-sided water channel (6), and as seen from the axial direction of the rotary shaft (1), a connecting water channel (54) which is provided between an inner surface (55) of the pump casing (5) and the tongue part (53), and which is directly connected to the inlet opening (6a) from the upstream side.
(FR) La présente invention concerne une pompe immergée (100) pourvue d'un canal d'eau unilatéral (6) s'étendant le long d'un arbre rotatif (1) sur un côté d'un corps principal de pompe immergée (100a), la pompe immergée (100) comprenant : une roue (4) ; et un carter de pompe (5) dans lequel la roue (4) est disposée sur le côté intérieur de celui-ci. Le carter de pompe (5), vu dans la direction axiale de l'arbre rotatif (1), comprend une partie languette (53) disposée entre une chambre de pompe (5a) dans laquelle la roue (4) est disposée et une ouverture d'entrée (6a) du canal d'eau unilatéral (6), et vu depuis la direction axiale de l'arbre rotatif (1), un canal d'eau de liaison (54) qui est disposé entre une surface intérieure (55) du carter de pompe (5) et la partie de languette (53), et qui est directement relié à l'ouverture d'entrée (6a) depuis le côté amont.
(JA) この水中ポンプ(100)は、水中ポンプ本体(100a)の片側に回転軸(1)に沿って延びる片側水路(6)が設けられた水中ポンプ(100)であって、羽根車(4)と、羽根車(4)が内側に配置されたポンプケーシング(5)とを備え、ポンプケーシング(5)は、回転軸(1)の軸方向から見て、羽根車(4)が配置されるポンプ室(5a)と片側水路(6)の入口開口(6a)との間に配置された舌部(53)と、回転軸(1)の軸方向から見て、ポンプケーシング(5)の内表面(55)と舌部(53)との間に設けられ、入口開口(6a)に上流側から直接接続される接続水路(54)とを含む。
