Title (EN) SHAFT SEALING APPARATUS AND VERTICAL SHAFT PUMP PROVIDED WITH SAME
(FR) APPAREIL D'ÉTANCHÉITÉ POUR ARBRE ET POMPE À ARBRE VERTICAL DOTÉE DUDIT APPAREIL
(JA) 軸封装置およびこの軸封装置を備えた立軸ポンプ
Abstract:
(EN) The present invention pertains to a shaft sealing apparatus that prevents leakage of a liquid from the shaft penetration part of a container penetrated by a rotary shaft. A shaft sealing apparatus (30) is provided with: a seal casing (70) that has a plurality of casing structures (33, 53) arranged along the axial direction of a rotary shaft (6); a plurality of seal chambers (33a, 53a) that are formed inside the respective casing structures; and a plurality of disk-shaped seal bodies (51) that have annular surfaces (31a, 51a) vertical to the shaft center of the rotary shaft, that are respectively housed in the seal chambers, and that rotate integrally with the rotary shaft. The casing structure have through-holes (35a, 55a) through which the rotary shaft passes and which are connected with the seal chambers, and the inner surfaces of the casing structures opposed to the annular surfaces of the seal bodies are planes vertical to the shaft center of the rotary shaft.
(FR) La présente invention concerne un appareil d'étanchéité pour arbre permettant d'empêcher les fuites de liquide à partir de la partie de pénétration d'arbre d'un récipient pénétré par un arbre rotatif. Un appareil d'étanchéité (30) pour arbre comprend : un carter d'étanchéité (70) comportant une pluralité de structures (33, 53) de carter disposées le long de la direction axiale d'un arbre rotatif (6) ; une pluralité de chambres d'étanchéité (33a, 53a) formées à l'intérieur des structures de carter respectives ; et une pluralité de corps d'étanchéité (51) en forme de disque et comportant des faces annulaires (31a, 51a) verticales par rapport au centre de l'arbre rotatif, les corps étant logés respectivement dans les chambres d'étanchéité et tournant d'un seul tenant avec l'arbre rotatif. La structure de carter comporte des trous traversants (35a, 55a) aptes à être traversés par l'arbre rotatif et reliés aux chambres d'étanchéité, et les faces internes des structures de carter opposées aux faces annulaires des corps d'étanchéité sont des plans verticaux par rapport au centre de l'arbre rotatif.
(JA) 本発明は、回転軸が貫通する容器の軸貫通部から液体が漏洩するのを防止する軸封装置に関する。 軸封装置(30)は、回転軸(6)の軸方向に沿って配置された複数のケーシング構造体(33,53)を有するシールケーシング(70)と、複数のケーシング構造体のそれぞれの内部に形成された複数のシール室(33a,53a)と、複数のシール室のそれぞれに収容され、回転軸と一体に回転し、回転軸の軸心に垂直な環状面(31a,51a)を有する複数の円板状のシール体(51)とを備える。各ケーシング構造体は、回転軸が貫通するとともに、シール室と連通する貫通孔(35a,55a)を有し、シール体の環状面に対向するケーシング構造体の内面は、回転軸の軸心に垂直な平面である。
