Title (EN) REACTION-TYPE TURBINE
(FR) TURBINE DU TYPE À RÉACTION
(KO) 반작용식 터빈
Abstract: front page image
(EN)A reaction-type turbine according to the present invention is configured in that a portion of a rotary shaft module which penetrates through a side with an inlet portion of a housing has a diameter larger than the diameters of other portions. Thus, the pressurized area in which a working fluid applies pressure to a rotary shaft in the direction opposite to the working fluid flow direction increases, thus increasing force in the direction opposite to the working fluid flow direction. As a result, axial direction force applied to the rotary shaft in the working fluid flow direction may be reduced. Therefore, the reaction-type turbine of the present invention has the advantages of eliminating the necessity of installing a separate thrust bearing for supporting axial force in the working fluid flow direction.
(FR)La présente invention porte sur une turbine du type à réaction conçue de telle sorte qu'une partie d'un module d'arbre rotatif qui pénètre à travers un côté présentant une partie d'entrée d'une enveloppe a un diamètre plus grand que le diamètre d'autres parties. De cette façon, la zone mise sous pression dans laquelle un fluide de travail applique une pression à un arbre rotatif dans le sens inverse du sens de l'écoulement de fluide de travail s'agrandit, accroissant ainsi la force dans le sens inverse du sens de l'écoulement du fluide de travail. Par suite, la force dans la direction axiale appliquée à l'arbre rotatif dans le sens de l'écoulement du fluide de travail peut être réduite. De cette façon, la turbine du type à réaction de la présente invention a les avantages d'éliminer la nécessité de monter un palier de butée séparé pour supporter la force axiale dans le sens de l'écoulement du fluide de travail.
(KO)본 발명에 따른 반작용식 터빈은, 회전축 모듈이 하우징 유입부가 형성된 측을 관통하는 부분의 직경이 다른 부분의 직경보다 크게 형성됨으로써, 작동유체가 유동방향의 반대방향으로 회전축에 압력을 가하는 가압 면적이 증가됨에 따라 유동방향의 반대방향으로의 힘이 증가되어, 회전축에 유동방향으로 가해지는 축방향 힘이 감소될 수 있다. 따라서, 유동방향의 축방향 힘을 지지하기 위한 별도의 스러스트 베어링을 설치할 필요가 없는 이점이 있다.
