Abrégé
(EN)
Disclosed in the present invention is a hydraulic turbine comprising: a turbine part equipped with a runner assembly that is rotated by a fluid which is introduced from a high pressure portion on one side and discharged to a low pressure portion on the other side; and a gear part having one end connected to the center of rotation of the runner assembly and the other end having a turbine shaft connected to a generator installed thereon, wherein the runner assembly is formed such that a plurality of runner segments, which have a lobe surface parallel to a rotary shaft having a predetermined thickness, are coupled in a twisted shape at a predetermined angle along the longitudinal direction of the rotary shaft. According to the present invention as described above, since the runner assembly is formed by stacking the plurality of runner segments in a twisted shape along the longitudinal direction of the rotary shaft, the flow of heating water is changed so as to swirl, thereby preventing pulsation from occurring in the wake of the runner assembly.

La présente invention concerne une turbine hydraulique comprenant : une partie turbine équipée d'un ensemble roue mobile qui est mis en rotation par un fluide qui est introduit à partir d'une partie haute pression sur un côté et évacué vers une partie basse pression de l'autre côté ; et une partie d'engrenage ayant une extrémité reliée au centre de rotation de l'ensemble roue mobile et l'autre extrémité ayant un arbre de turbine relié à un générateur installé sur celui-ci, l'ensemble roue mobile étant formé de telle sorte qu'une pluralité de segments de roue mobile, qui ont une surface de lobe parallèle à un arbre rotatif ayant une épaisseur prédéterminée, soient couplés en une forme torsadée selon un angle prédéterminé le long de la direction longitudinale de l'arbre rotatif. Selon la présente invention telle que décrite ci-dessus, étant donné que l'ensemble roue mobile est formé par empilement de la pluralité de segments de roue mobile sous une forme torsadée le long de la direction longitudinale de l'arbre rotatif, l'écoulement d'eau de chauffage est changé de manière à tourbillonner, ce qui permet d'empêcher une pulsation de se produire dans le sillage de l'ensemble roue mobile.

본 발명에서는, 일측의 고압부로부터 유입된 후 타측의 저압부로 배출되는 유체에 의해 회전하는 회전차 어셈블리가 장치되어 있는 터빈부와; 일단은 상기 회전차 어셈블리의 회전 중심에 연결되며, 타단은 발전기에 연결되는 터빈축이 장치되어 있는 기어부를 포함하고, 상기 회전차 어셈블리는, 소정 두께의 회전축과 나란한 로브 면을 가지는 복수개의 회전차 세그먼트를 회전축 방향을 따라 소정각도로 트위스트 되는 형태로 결합한 것을 특징으로 하는 수력 터빈이 개시된다. 이상과 같은 본 발명에서 회전차 어셈블리는 복수개의 회전차 세그먼트를 회전축 방향을 따라 트위스트된 형태로 적층하여 형성함으로써 난방수의 흐름을 휘어지도록 변경하여 회전차 어셈블리 후류에서 펄세이션(pulsation)이 발생하지 않도록 한다.
