Definitions
- the present invention relates to the technical field of steam turbines.
- the present invention relates insbesonde re ⁇ a blade module for attachment to a drive acting ⁇ felkranz a steam turbine, a steam turbine with several such blade modules and a method for manufacturing such a blade module.
- a steam turbine generally has a series of rotor blades which are mounted side by side on an axis of rotation.
- Each blade ring has a plurality of rotor blades, which have a shape optimized in terms of fluid dynamics.
- the rotor blades may be modular, with each module having a base plate, an airfoil and a fastener.
- the foot plates and fasteners for the blades must i.a. be designed so that the design default number of blades on the blade ring fit next to each other and so that a predetermined maximum distance to an adjacent blade ring can be maintained. Due to these restrictions with regard to the shape and size of the individual parts, undesired stress concentrations can arise, in particular in the transition region between the blade and the foot plate / fastening means.
- the object of the present invention is to reduce or avoid such stress concentrations.
- a blade module for mounting on a rotor part for forming a blade ring in a steam turbine comprises: (a) a base plate, (b) an airfoil that extends from one side of the base plate, and (c) a Befest Trentsmit ⁇ tel which extends from the other side of the base plate, wherein a projection the airfoil to the foot plate ⁇ -containing layer is completely covered by the base plate.
- the described blade module is based on the finding that stress concentrations can be significantly reduced or completely avoided if the projection of the blade onto the soleplate plane is completely covered by the soleplate, that is to say that the profile of the airfoil does not overlap the edge of the base plate protrudes.
- This property is to be achieved in particular by the form ⁇ nosti the footplate, in particular the edge of the base plate, as the shape of the airfoil is CARDINAL ⁇ Lich fluid dynamic conditions.
- Base plate a quadrangular shape with pairwise parallel
- the base plate is rhomboid-shaped or diamond-shaped.
- two opposing edges of the foot plate for example, perpendicular to the axis of rotation of the rotor while the two other opposing edges are not parallel to the axis of rotation.
- the foot plate has no angle which is 90 °.
- the fastening means has a plurality of tabs, which for Attach the blade module to the rotor section
- Forming of the blade ring are set up.
- the tabs may in particular have a quadrilateral shape and parallel to each other and perpendicular to the rotational axis ⁇ net angeord.
- the tabs fit into corresponding grooves in the rotor member and can be secured therein.
- the tabs on a through hole for receiving a tapered pin is used to attach the Laufschaufelmo ⁇ module.
- the through hole running through the center of each link plate and parallel to an edge of the foot plate that is neither parallel nor perpendicular ⁇ right to a rotational axis of the rotor blade ring.
- the central through bore results in a stable as possible struc- ture when the blade module is attached (for example by means troduction ⁇ proceedings of a tapered pin into the through hole) on the rotor ⁇ part because the stressed cross section of the flaps (the level of the hole) on both sides of the same is great.
- the foot plate, the blade and the fastening means are integrally formed.
- a steam turbine is described.
- the steam turbine described comprises (a) at least one rotor part and (b) a plurality of rolling show ⁇ felmodulen according to the first aspect or any one of the above embodiments, wherein the blade modules are attached to form a blade ring on the rotor part. Due to the use of the advantageous blade modules, this steam turbine benefits from the advantages described above. In particular, results in comparison with other steam turbines a longer life and a lower risk of failure.
- a method of manufacturing a blade module for mounting on a rotor part to form a blade ring in a steam turbine comprises: (a) providing a base plate, (b) providing an airfoil that extends from one side of the base plate, and (c) providing a Fixed To ⁇ supply means extending from the other side of the base plate, wherein a projection of the airfoil on a footplate-containing plane is completely covered by the foot plate ⁇ dig.
- This aspect basically relates to a method of manufacturing a blade module according to the first aspect.
- Base plate a quadrangular shape with pairwise parallel
- the footplate may in particular be rhomboidal.
- the attachment means comprises a plurality of tabs adapted to secure the blade module to the rotor member, and the method further comprises forming a throughbore through the tabs to receive a bevel pin.
- the method further comprises forming a recess in one
- Figure 1A shows a first side view of a conventional blade module.
- Figure 1B shows a second side view of the conventional blade module.
- Figure IC shows a plan view of the conventional Laufschau ⁇ felmoduls.
- Figure 2 shows another view of the conventional run ⁇ shovel module.
- FIG. 3 shows a partial view of a rotor part with three conventional moving blade modules.
- Figure 4 shows a plan view of a blade module according to the present invention.
- Figure 5 is a sectional view of a foot strap of a blade module according to the present invention.
- FIG. 1A to 1C show various views of a conventional blade module 1. More specifically, FIG. 1A shows a first side view of the blade module 1 with airfoil 2 and base plate 3. FIG. 1B shows a second side view of the blade module 1 relative to the first side view in FIG 1A is turned 90 °. In Figure 1B tabs 4 can be seen. The lugs 4 represent a fastening means for mounting the blade module 1 on a rotor part with corresponding grooves.
- FIG. IC shows a plan view of the blade module 1.
- the projection of the blade 2 lies on the plane of the base plate 3 In other words, a part of the profile of the airfoil 2 protrudes beyond the edge of the base plate 3.
- the arrow 6 shows the direction of the incoming steam.
- FIG. 3 shows a partial view of a rotor part 7 with three conventional running blade modules 1 mounted side by side. More specifically, the tabs 4 of each run ⁇ scoop module 1 are inserted into corresponding grooves 8 of the rotor part 7 and two fasteners, in particular conical pins 9 (per module) pass through corresponding holes in the tabs 4 and thus hold the modules 1 on the rotor part 7 fixed ,
- FIG. 4 shows a plan view of a blade module 11 according to the present invention.
- the blade module 11 has an airfoil 12 and a base plate 13. Rectangular base plate 3 deviate ⁇ accordingly shown by in FIG IC (and in Figure 4 also in phantom), the foot ⁇ plate 13 of the rotor blade module of the invention 11 designed so that the projection of the airfoil 12 on the plane completely inside the edge of the Foot plate 13 is located. In the illustration shown, this is achieved in that the foot plate is rhomboid-shaped or diamond-shaped. In other words, although the shape of the foot plate is quadrangular and the opposing edges 13a and 13b are pairwise parallel, the shape is not at right angles.
- Figure 4 further shows the outer surfaces 7a, 7b of the rotor 7.
- the rotor blade part module 11 is Zvi ⁇ rule the outer surfaces 7a, 7b mounted.
- the rotor blade module 11 also has tabs (not visible in FIG. 4) with a through bore whose axis 14 is shown schematically.
- This axis 14 extends parallel to and in the middle between (in this embodiment) longer edges 13a of the footplate 13.
- a recess 15 may be provided in one of the outer side surfaces 7a, 7b of the rotor member 7 which forms a surface perpendicular to the direction of the axis 14.
- the arrow 16 shows the turbine longitudinal axis.
- FIG. 5 shows a sectional view of a foot strap 17 of the blade module 11 shown in FIG. 4 according to the present invention.
- the foot-plate 17 as shown has a cross sectional shape corresponding to the shape of the foot plate 13 and has a central through bore 18 into which a buildin ⁇ actuating element, for example a tapered pin can be inserted. This is done according to the same principle that in
