Title (EN) PUMP
(FR) POMPE
(JA) ポンプ
Abstract:
(EN) The present invention relates to a pump for transferring fluid. A pump is provided with: an upper casing (3a) and a lower casing (3b), which accommodate an impeller (2) affixed to a rotating shaft (1); and a seal member (22) gripped between the upper casing (3a) and the lower casing (3b). The upper casing (3a) and the lower casing (3b) are respectively provided with an upper flange (8) and a lower flange (9), which have mating faces (21, 20) for gripping the seal member (22). The upper flange (8) and the lower flange (9) respectively have formed therein a plurality of fastening holes (16, 17) into which fasteners (10) for fastening the upper casing (3a) and the lower casing (3b) are inserted. The mating face (21) of the upper flange (8) has a plurality of recesses (14) formed therein.
(FR) La présente invention concerne une pompe destinée à transférer un fluide. Une pompe comporte : un boîtier supérieur (3a) et un boîtier inférieur (3b) qui logent une roue à aubes (2) fixée sur un arbre rotatif (1) ; et un élément d'étanchéité (22) saisi entre le boîtier supérieur (3a) et le boîtier inférieur (3b). Le boîtier supérieur (3a) et le boîtier inférieur (3b) sont respectivement pourvus d'une bride supérieure (8) et d'une bride inférieure (9) qui ont des faces d'accouplement (21, 20) pour saisir l'élément d'étanchéité (22). La bride supérieure (8) et la bride inférieure (9) ont respectivement, formée en leur sein, une pluralité de trous de fixation (16, 17) dans lesquels sont insérées des pièces de fixation (10) pour fixer le boîtier supérieur (3a) et le boîtier inférieur (3b). La face d'accouplement (21) de la bride supérieure (8) a une pluralité d'évidements (14) formée en son sein.
(JA) 本発明は、流体を移送するポンプに関するものである。 ポンプは、回転軸(1)に固定された羽根車(2)を収容する上ケーシング(3a)および下ケーシング(3b)と、上ケーシング(3a)と下ケーシング(3b)との間に挟まれたシール部材(22)とを備える。上ケーシング(3a)および下ケーシング(3b)は、シール部材(22)を挟む合わせ面(21,20)を有する上フランジ(8)および下フランジ(9)をそれぞれ備えている。上フランジ(8)および下フランジ(9)には、上ケーシング(3a)と下ケーシング(3b)とを締結するための複数の締結具(10)が挿入される複数の締結穴(16,17)がそれぞれ形成されている。上フランジ(8)の合わせ面(21)には、複数の凹み部(14)が形成されている。
