Description

Dans une turbine, ou partie de turbine à échappement axial l'un des paliers qui supporte le rotor est intégré dans le fond d'échappement.In a turbine, or part of a turbine with axial exhaust, one of the bearings which supports the rotor is integrated in the exhaust bottom.

Ce palier est tenu par l'intermédiaire de tirants judicieuse­ment placés dans le fond d'échappement qui reportent les efforts normaux et accidentels du rotor sur les pattes d'appui et sur le centrage transversal du stator, les pattes et le centrage transversal du stator étant en appui sur le radier.This bearing is held by means of tie rods judiciously placed in the exhaust bottom which transfer the normal and accidental forces of the rotor to the support legs and to the transverse centering of the stator, the legs and the transverse centering of the stator being resting on the raft.

Cette disposition constructive laisse apparaître une certaine faiblesse. En effet le bon comportement dynamique du rotor ainsi que sa sécurité vis-à-vis des grands balourds accidentels exigent du palier une grande raideur difficile à obtenir par le système à tirants.This constructive disposition reveals a certain weakness. Indeed, the good dynamic behavior of the rotor as well as its safety with regard to large accidental unbalances require from the bearing a great stiffness which is difficult to obtain by the tie rod system.

En outre, à chaque azimut correspond une raideur différente ce qui rend plus difficile la tenue de la ligne d'arbres lors de balourds dynamiques accidentels importants.In addition, each azimuth corresponds to a different stiffness which makes it more difficult to hold the line of trees during significant accidental unbalance.

Tous les efforts transitent par le palier ou par l'étrier, les tirants, les pattes d'appui et le centrage transversal du stator et le radier.All the forces pass through the bearing or the stirrup, the tie rods, the support legs and the transverse centering of the stator and the base.

De plus l'augmentation constante de sections échappements conduit à des sollicitations dynamiques de plus en plus importantes dans des stators de dimensions plus grandes encore.In addition, the constant increase in exhaust sections leads to increasing dynamic loads in stators of even larger dimensions.

On connaît également du document FR-A-7 510 810 une installation de turbine à gaz dans laquelle le palier est tenu par deux béquilles reliées au radier.Document FR-A-7 510 810 also discloses a gas turbine installation in which the bearing is held by two crutches connected to the raft.

Une telle installation présentera un mauvais comportement dynamique étant donné que seuls les efforts dans le sens verticaux sont compensés.Such an installation will exhibit poor dynamic behavior since only the forces in the vertical direction are compensated.

Par contre les efforts importants dans le sens horizontal vont entraîner une forte déformation de la structure.By cons significant efforts in the horizontal direction will cause a strong deformation of the structure.

Enfin les béquilles sont longues et présentent une raideur insuffisante pour supporter les gros balourds.Finally the crutches are long and have insufficient stiffness to support large unbalances.

Un des buts du système de support selon l'invention défini par les revendications est d'augmenter la raideur du palier suppor­tant le rotor et d'assurer dans de meilleures conditions la tenue du palier vis-à-vis d'accidents majeurs (par exemple perte d'une dernière ailette BP). De plus grâce à la séparation de la fonction palier de la fonction stator, tout balourd du rotor ne peut exciter un mode propre de la structure du stator.One of the aims of the support system according to the invention defined by the claims is to increase the stiffness of the bearing supporting the rotor and to ensure, under better conditions, the bearing behavior with regard to major accidents (for example loss of one last BP fin). In addition, thanks to the separation of the bearing function from the stator function, any unbalance of the rotor cannot excite a specific mode of the structure of the stator.

La présente invention sera mieux comprise à la lumière de la description qui va suivre dans laquelle :

  • Les figures 1 et 2 représentent un système de supportage du rotor pour turbine à échappement axial selon les dispositions actuelles en vue de côté et en vue de dos.
  • Les figures 3 et 4 représentent le système de supportage du rotor selon l'invention en vue de côté et en vue de dos.
  • Les figures 5 et 6 représentent le système de supportage du rotor des figures 3 et 4 en perspective vue du côté admission et vue du côté échappement.
The present invention will be better understood in the light of the description which follows in which:
  • Figures 1 and 2 show a rotor support system for an axial exhaust turbine according to the current arrangements in side view and in back view.
  • Figures 3 and 4 show the rotor support system according to the invention in side view and in back view.
  • Figures 5 and 6 show the rotor support system of Figures 3 and 4 in perspective viewed from the intake side and viewed from the exhaust side.

Les figures 1 et 2 représentent une turbine connue ayant un échappement axial 1 faisant partie du stator 2. Cette turbine comporte un palier 3 supporté par un appui 4 en béton faisant partie d'un radier 5 en béton situé du côté de l'admission 6 et un autre palier 7 du côté de l'échappement 1.Figures 1 and 2 show a known turbine having an axial exhaust 1 forming part of the stator 2. This turbine comprises a bearing 3 supported by a concrete support 4 forming part of a concrete base 5 located on the inlet side 6 and another bearing 7 on the side of the exhaust 1.

Le palier 7 comporte un coussinet 8 et un étrier 9 qui supporte le rotor 10 ainsi qu'une garniture vapeur 11. Cette garniture 11 assure l'étanchéité entre la vapeur et la pression atmosphérique à laquelle elle est reliée par une canalisation 20.The bearing 7 comprises a pad 8 and a stirrup 9 which supports the rotor 10 as well as a vapor lining 11. This lining 11 provides a seal between the steam and the atmospheric pressure to which it is connected by a pipe 20.

Le palier 7 est supporté par des tirants 12 fixés à leurs extrémités sur la paroi d' échappement 1.The bearing 7 is supported by tie rods 12 fixed at their ends on the exhaust wall 1.

L'échappement 1 est muni de deux pattes latérales 13 qui reposent sur des appuis en béton 14 solidaires du radier 5.The exhaust 1 is provided with two lateral legs 13 which rest on concrete supports 14 integral with the raft 5.

Un dispositif de centrage transversal 15 est situé à la partie inférieure de l'échappement. Ce dispositif 15 comporte deux barres horizontales 16 boulonnées à une extrémité sur des attaches 17 solidaires du bas de l'échappement et à l'autre extrémité sur des attaches 18 fixées sur le radier en béton 5.A transverse centering device 15 is located at the bottom of the exhaust. This device 15 comprises two horizontal bars 16 bolted at one end to fasteners 17 secured to the bottom of the exhaust and at the other end to fasteners 18 fixed to the concrete slab 5.

Pour faciliter l'accès au palier 7 sans avoir à démonter la partie supérieure du stator 2, l'échappement 1 comporte une demi-pièce intermédiaire 19 démontable par l'intermédiaire de deux demi-brides verticales.To facilitate access to the bearing 7 without having to dismantle the upper part of the stator 2, the exhaust 1 comprises an intermediate half-piece 19 which can be dismantled by means of two vertical half-flanges.

Les efforts normaux et accidentels du rotor 10 sont reportés par les tirants 12 sur la paroi de l'échappement qui les transmet aux pattes 13 et/ou au dispositif de centrage 15.The normal and accidental forces of the rotor 10 are transferred by the tie rods 12 to the wall of the exhaust which transmits them to the lugs 13 and / or to the centering device 15.

Dans le système de supportage connu en cas de balourds acciden­tels importants il y a des risques de détérioration du palier 7 et du système de support surtout lorsque les dimensions des pièces en jeu sont très importantes.In the known support system in the event of significant accidental imbalances there is a risk of deterioration of the bearing 7 and of the support system, especially when the dimensions of the parts in play are very large.

De plus, les tirants 12 répartis sur toute la circonférence à l'intérieur de l'échappement sont générateurs d'une perte de charge relativement importante.In addition, the tie rods 12 distributed over the entire circumference inside the exhaust generate a relatively large pressure drop.

Le système de supportage selon l'invention est représenté sur les figures 3 à 6. Les parties similaires à celles du système connu portent les mêmes références.The support system according to the invention is shown in Figures 3 to 6. Parts similar to those of the known system have the same references.

Le rotor 10 de la turbine est supporté par deux paliers 3 et 7, l'un situé du côté de l'admission 6, l'autre dans l'échappement axial 1.The rotor 10 of the turbine is supported by two bearings 3 and 7, one located on the intake side 6, the other in the axial exhaust 1.

Le palier 3 est supporté par un appui en béton 4 solidaire du radier en béton 5.The bearing 3 is supported by a concrete support 4 integral with the concrete slab 5.

Le palier 7 comporte un coussinet 8 sur lequel est fixé un étrier 9 et une garniture vapeur 11.The bearing 7 comprises a pad 8 on which is fixed a stirrup 9 and a steam lining 11.

La garniture 11 est mise à la pression atmosphérique par une canalisation 20.The lining 11 is brought to atmospheric pressure by a line 20.

Selon l'invention, on a prévu un mur vertical en béton 21 solidaire du radier 5 comportant une ouverture demi-circulaire 22 dans lequel vient se loger la partie inférieure de l'échappement 1.According to the invention, a vertical concrete wall 21 is provided integral with the raft 5 comprising a semicircular opening 22 in which the lower part of the exhaust 1 is housed.

Le palier 7 est supporté par quatre tirants 12 rayonnants et situés dans un plan vertical perpendiculaire à l'axe du rotor. Deux tirants sont horizontaux et les deux autres sont dirigés vers le bas et écartés d'un angle de 60° avec les tirants voisins.The bearing 7 is supported by four radiating tie rods 12 and located in a vertical plane perpendicular to the axis of the rotor. Two tie rods are horizontal and the other two are directed downwards and spaced at an angle of 60 ° with the neighboring tie rods.

Les tirants 12 sont ancrés à leurs extrémités dans l'épaisseur du mur 21 autour de l'ouverture demi-circulaire 22.The tie rods 12 are anchored at their ends in the thickness of the wall 21 around the semicircular opening 22.

Les tirants 12 sont munis de soufflets d'étanchéité 24 au niveau de leur traversée de la paroi de l'échappement 1.The tie rods 12 are provided with sealing bellows 24 at their crossing of the wall of the exhaust 1.

La partie inférieure de l'échappement 1 est solidaire du stator 12, elle est munie de deux pattes latérales 13 qui reposent sur le massif en béton 14 solidaires du radier 5.The lower part of the exhaust 1 is integral with the stator 12, it is provided with two lateral lugs 13 which rest on the concrete block 14 integral with the raft 5.

Un dispositif de centrage 15 du stator est situé côté échappe­ment 1. Il comporte une clavette 25 montée sur un appui en béton 26 solidaire du radier 5, ladite clavette 25 étant emprisonnée dans une glissière 27 parallèle à l'axe de la turbine et solidaire de l'échappement.A centering device 15 of the stator is located on the exhaust side 1. It comprises a key 25 mounted on a concrete support 26 integral with the base 5, said key 25 being trapped in a slide 27 parallel to the axis of the turbine and integral with the exhaust.

Les appuis 4, 14, 26 et le mur 21 sont de préférence en béton et sont directement intégrés au radier 5 et constituent avec celui-­ci un massif. Il y a bien sûr toute possibilité de réaliser ces appuis dans une structure acier.The supports 4, 14, 26 and the wall 21 are preferably made of concrete and are directly integrated into the raft 5 and constitute with it a solid. There is of course any possibility of carrying out these supports in a steel structure.

La transmission des efforts du palier ne passent plus par le stator 2 et l'échappement 1 puisque les tirants 12 sont scellés au mur en béton 21 ; le système selon l'invention est particulière­ment simple et peut encaisser ainsi de très grands balourds acciden­tels tout en conservant l'intégrité du supportage du rotor.The transmission of the bearing forces no longer pass through the stator 2 and the exhaust 1 since the tie rods 12 are sealed to the concrete wall 21; the system according to the invention is particularly simple and can thus absorb very large accidental unbalances while retaining the integrity of the support of the rotor.

Les tirants 12 nécessaires à la transmission de ces efforts sont beaucoup moins nombreux que ceux qui devraient être utilisés dans le système connu. Les pertes de charge à l'échappement sont donc ainsi minimisées.The tie rods 12 necessary for the transmission of these forces are much less numerous than those which should be used in the known system. The pressure losses at the exhaust are thus minimized.

Enfin puisque le palier 7 ne transmet pas d'efforts à l'échap­pement 1 les appuis 14 supportant les pattes latérales 13 peuvent être de construction moins massive et le dispositif de centrage 15 peut être un simple dispositif à clavette.Finally since the bearing 7 does not transmit forces to the exhaust 1 the supports 14 supporting the side tabs 13 can be of less massive construction and the centering device 15 can be a simple key device.

L'accès au palier côté échappement est particulièrement aisé et se fait par démontage de la demi-partie supérieure 19 de l'échap­pement 1, le palier 7 ancre directement sur le radier restant en place.Access to the bearing on the exhaust side is particularly easy and is done by dismantling the upper half-part 19 of the exhaust 1, the bearing 7 anchors directly on the raft remaining in place.
