Definitions

  • the invention relates to methods for producing a turbine rotor according to the preamble of claim 1 and a turbine rotor according to the preamble of claim 2.
  • the rotor of a turbine used to generate electricity including a steam turbine, is subject to high loads.
  • a variety of design options have been devised, all of which have certain advantages, but of course also disadvantages.
  • a particularly solid, but equally complex manufacturing method is to forge a one-piece runner from the solid.
  • the required before manufacturing Material can only be ordered after receipt of the order and often requires a long delivery time, which is not least caused by the small number of suppliers available.
  • prefabrication independent of the order and also no parallel processing of individual parts is possible, so that long production lead times result. Difficulties also arise when inserting impeller blades, insofar as the blade feet can be inserted axially, since a larger axial distance between the impeller disks is required for machining the groove in order to be able to work with appropriate tools. However, wide distances between the impellers degrade the rotor dynamics.
  • the object of the invention is to provide a method for producing a rotor and a rotor for a turbine according to the preamble of claim 1 and the preamble of claim 2, which enables simple production with a short lead time.
  • the steam shaft end can be finished except for the bearings, the compensating piston and, if necessary, the blade attachment.
  • the exhaust steam shaft end can be finished except for the bearings and the coupling connection and the impellers can be finished except for the outer diameter in the weld area.
  • the impellers can also be manufactured entirely as castings, whereby Powdermet can also be used.
  • Another essential advantage of the method according to the invention is that it is possible to build particularly compact short runners with better dynamic properties due to the reduced weight. Since the largely finished machined disks are already provided with the grooves required for their blading, it is no longer necessary to ensure that their mutual distance is large enough to provide adequate tools for machining the grooves. The distance between the adjoining running disks can thus be minimized from a rotor dynamic point of view.
  • a double rotor washer has proven to be a particularly advantageous part of the modular system, since it can be used to optimize the modularization.
  • By combining two rotor disks for a double running disk on the one hand a high stability of the component is guaranteed, and on the other hand good accessibility is achieved, in particular when machining the grooves for the base parts of the blades, and in addition the number of weld seams is reduced by using individual disks.
  • the blades can also be comfortably inserted axially with their blade base into the correspondingly shaped grooves.
  • the rotor parts expediently have an axial bore which serves to receive an axial tie rod which holds the parts together, so that they can be connected to one another by electron beam welding.
  • the modular system designed for the manufacture of a rotor includes, in addition to the already mentioned double running disks, single running disks, steam shaft ends, steam shaft ends and condensation end stage drums.
  • a recess is provided in the rotor parts, at least on one side symmetrical to the central axis, through which a ring-shaped sleeve which is symmetrical to the axis is created, which lies against the adjacent rotor part and defines the position of the welding night.
  • the annular cuff is made of a lighter welding material, preferably a steel with a lower carbon and / or nickel content than other areas of the rotor part. This can be done by appropriate processing methods such. B. melting in a vacuum or a slag melt can be achieved.
  • the region of the rotor disks which is located further away from the central axis and to which the blades are fastened from a steel of higher mechanical strength.
  • the annular sleeve and possibly also the rest of the rotor disk can be made from a material that is easy to weld.
  • toothings are provided on the outer region of the rotor parts which are located towards the central axis and which engage in corresponding toothings of the adjacent rotor part. These gears can absorb at least part of the rotational forces, which relieves the pressure on the weld seams. It is expedient to then produce these toothings from a steel with higher mechanical strength.
  • the section of a rotor shown in FIG. 1 corresponds to a section of FIG. 2.
  • the rotor of this embodiment consists of an inlet steam shaft end 1, two double rotor disks 3, a single rotor disk 2 and an exhaust steam shaft end 4.
  • a control wheel 6 is part of the steam shaft end 1, but it does can also be further divided.
  • a condenser output stage drum 5 is added to the rotor parts 1 to 4 already listed.
  • the rotor parts 1 to 5 are provided with different recesses 7a, 7b, 7c, which ensure that ring-like sleeves 9a, 9b are formed which overlap one another and thus bring about a concentric alignment with the axis.
  • All rotor parts have an axial bore through which a tie rod 8 is guided, which is screwed into the steam shaft end 1 and holds the rotor parts 1 to 5 together.
  • a tie rod 8 is guided, which is screwed into the steam shaft end 1 and holds the rotor parts 1 to 5 together.
  • weld seams 13 can now be made by electron beam welding, which ensure that the rotor parts 1 to 5 are connected to a single rotor.
  • the tools required for cutting the grooves can be used both for the single discs 2 and for the double discs 3 can be conveniently introduced from the outside. It is thus possible to implement any desired groove shape, as shown in FIGS. 4 and 5, and to insert blades 10 with their blade roots 11 and 12 axially into the rotor disks 2.
  • This disc construction therefore enables any type of blade attachment and its manufacture can be carried out in a simple manner on smaller machine tools. Processing with welded-on blades or complex pulleys made of powder metal is also possible. Very short throughput times can be achieved through parallel processing.
