Definitions
- the invention relates to a spiral of a turbomachine, which consists of a number of interconnected segments and at least one parallel plate, and an application of such a spiral in a hydropower plant.
- spirals of fluid-flow machines such as turbines, pump turbines or pumps
- the spirals of fluid-flow machines are generally formed from individual segments welded together.
- the object of the invention has now set itself the task of specifying a spiral, which makes it possible to use thinner sheets for the spiral and at the same time improves the flow of the spiral.
- a reinforcing plate which forms part of the shell of the spiral is arranged on at least one connecting joint between two segments of the spiral and / or in the region of the transition from the spiral to the parallel plate.
- the reinforcement plates also cause a weaker deflection of the liquid medium in the spiral, which improves the flow contour in the spiral.
- a particularly voltage-reducing and flow-improving configuration is obtained if the reinforcing plate is triangular.
- the reinforcement plates are advantageously used in such a way that the inner contour of the spiral is essentially retained by the reinforcement plate, with the result that the flow contour of the spiral is improved by the gentler deflections that result. This reduces flow losses and improves efficiency.
- the reinforcement plates are only arranged in the area of the spiral with the largest diameters, since the greatest loads occur there and the reinforcement plates can therefore also have the greatest effect.
- At least one reinforcing plate is advantageously arranged on both sides of the transitions to the parallel plate.
- a spiral according to the invention can be produced simply by welding the segments and welding the reinforcement plates into recesses in the spiral or welding the reinforcement plates on.
- Fig. 1 shows a part of a spiral with reinforcing sheets according to the invention and Fig. 2 shows a cross section through the spiral with a parallel plate.
- a section of a spiral 1 of a turbomachine such as a Francis turbine, a pump turbine or a pump, which is composed of several segments 2 for reasons of production technology.
- the segments 2 are welded to one another along the segment joints 5.
- the spiral 1 is welded to a parallel plate 3 to which other components of the turbomachine, such as a turbine cover, the stator ring, etc., can be flanged.
- well-known support blades or other suitable connecting elements such as spacer supports, etc., not yet shown here, could also be arranged.
- the spiral 1 with the largest cross-sectional diameters, i.e.
- reinforcement plates 4 are now arranged in the intersection area of the segment joints 5 with the parallel plate 3, i.e. in the area in which the greatest stresses and loads normally occur.
- the reinforcement plates 4 are designed triangular here and are welded into recesses in the casing of the spiral 1, so that the base of the triangle is connected to the parallel plate 3 and the two legs of the triangle converge at the segment joint 5 to form a rounded tip.
- the shape of the reinforcement plate is of course not limited to a triangle, but any other shape, such as an elliptical or oval reinforcement plate, is also conceivable.
- the circular inner contour of the spiral is essentially retained.
- the internal contour could be changed by the reinforcement plates 4 for fluidic or voltage-related reasons, e.g. the radius of the reinforcement plate 4 could be chosen somewhat larger than the inner spiral radius.
- the reinforcing plate 4 is thicker here than the rest of the spiral 1, or better expressed, the plate thickness of the spiral 1 can be chosen thinner than before by the stress-reducing effect of the reinforcing plates 4, which results in a considerable weight saving of the spiral 1.
- a reinforcing plate 4 is used on both sides of the parallel plate 3.
- the number of segments is doubled from the view of the parallel plate 3 through the reinforcement plates 4, since the reinforcement plate 4 actually functions as a segment in the region of the parallel plate 3. This reduces the opening angle of the individual segments, which in turn leads to smaller voltage peaks.
- the reinforcement plates 4 also have an advantageous flow effect, since the reduced deflection of the medium reduces the risk of the medium detaching from the spiral skin, and the flow contour is thus improved.
