Title (EN) AXIAL FLOW TURBINE HAVING A DIAPHRAGM SPLIT IN TWO HALVES AT A HORIZONTAL JOINT PLANE
(FR) TURBINE À FLUX AXIAL AYANT UN DIAPHRAGME FENDU EN DEUX MOITIÉS AU NIVEAU D'UN PLAN DE JOINT HORIZONTAL
Abstract:
(EN) An axial flow turbine comprising a casing (14), a rotor (12) having an axial rotational axis (Z) and rotatably mounted into said casing (14),at least one set of a plurality of moving blades (16) supported by said rotor; and at least one diaphragm (18) having an outer ring (22), an inner ring (24), concentric to the outer ring, and a plurality of static blades (26) mounted therebetween, at least said outer ring (22) being split in an upper half (22a) and a lower half (22b) along a vertical joint plane (P). The turbine diaphragm (18) comprises an assembly system (30) for assembling the upper half (22a) to the lower half (22b) while allowing the upper half (22a) and the lower half (22b) to move axially relative to each other.
(FR) L'invention concerne une turbine à flux axial comprenant un carter (14), un rotor (12) ayant un axe de rotation axial (Z) et monté de manière rotative dans le carter (14), au moins un ensemble d'une pluralité de pales mobiles (16) supportées par le rotor; et au moins un diaphragme (18) ayant un anneau externe (22), une bague interne (24) concentrique à la bague externe, et une pluralité de pales statiques (26) montées entre celles-ci, au moins la bague externe (22) est divisée dans une moitié supérieure (22a) et une moitié inférieure (22b) le long d'un plan de joint vertical (P). Le diaphragme de turbine (18) comprend un système d'assemblage (30) pour assembler la moitié supérieure (22a) à la moitié inférieure (22b) tout en leur permettant de se déplacer axialement l'une par rapport à l'autre.
