Definitions
- the invention relates to a device for sealing between the vanes and the rotor of turbomachinery with the Features of the preamble of claim 1.
- a cooled honeycomb seal is known, the at the outer boundary of the flow channel inside a gas turbine is arranged.
- the honeycomb seal is a part of the cooling air, which is the upstream Guide vane is available on the outer shroud, through Holes in the honeycomb ring bearing the Honeycomb supplied.
- the invention is based on the object, the generic Seal so that the distance between the Honeycomb seal and the labyrinth tips to reduce the Leakage currents while increasing the efficiency of Turbomachine can be reduced.
- the sealing gap can be from be designed narrower in the front.
- turbomachines The construction of turbomachines is basically known.
- a formed as a gas turbine turbomachine is shown in FIG. 7 from a housing 16 in which a rotor 17 is rotatably mounted.
- the rotor 17 carries a plurality of rows of blades 18, between which fixed, attached to the housing 16 vanes. 1 are arranged.
- Figs. 1 to 5 and 9 to 11 is a part of the rotor 17 with two blades 18 and the lower part of a vane. 1 shown.
- the vane 1 is at its end facing the rotor 17 provided with a Leitschaufelfuß 14.
- a Leitschaufelfuß 14 At the Leitschaufelfuß 14 is heat-elastic, an inner ring 3 suspended.
- the Leitschaufelfuß 14 provided with a projection 19 which in an adapted recess 20 engages in the inner ring 3, wherein between the end face of the projection 19 of the Leitschaufelfußes 14 and the bottom of the recess 20 of the inner ring 3 a the Thermal expansion receiving gap 13 remains.
- Centering pins 2, in the projection 19 of the vane root 14 and in the bottom the recess 20 of the inner ring 3 are used, provide for a centering of the inner ring 3 on the Leitschaufelfuß 14th
- honeycomb seal 4 On the rotor 17 facing surface of the inner ring 3 is a honeycomb seal 4 soldered.
- the honeycomb seal 4 contains an open honeycomb structure made up of webs. The Webs are connected to the inner ring 3 and limit the after inside open honeycomb.
- the honeycomb seal 4 are labyrinth peaks 5 of a one-piece sealing labyrinth ring opposite, which is mounted on the rotor 17. Between the with the rotor 17 rotating labyrinth tops 5 and the fixed honeycomb seal 4 is a sealing gap of small to be held radial height.
- the guide vanes 1 are cooled and have a cavity 21 on, which is traversed by cooling air.
- the cooling air occurs at the Vane trailing edge 6 off.
- the cooling air is taken from the vane 1. To this end is through the Leitschaufelfuß 14 a first flow channel guided, which is designed as a bore 15 and into the gap 13th between the Leitschaufelfuß 14 and the inner ring 3 opens.
- the first flow channel can also be shown in FIG. 8 as an inner bore 23 of a hollow centering pin 2 may be formed, wherein the Inner bore 23 via a radially through the Leitschaufelfuß 14th guided bore 24 with the cavity 21 of the guide vane 1 in Connection stands.
- the inner bore 23 of the hollow Centering pin 2 is at least one of the second as well Flow channel serving, radial bores 7 connected. In each case one of the radial bores 7 opens into one of the axial holes 8 a.
- At least one of the radial bores 7, which serve as second flow channels, branch off fourth flow channels, as the oblique holes. 9 are guided by the inner ring 3 and in a further annular groove 22 end. In this way, the honeycomb seal 4 is a large area cooled.
- the inner ring 3 consists of two parts, the on the mutually facing sides with grooves and projections are provided.
- the two parts of the inner ring 3 are so put together that the grooves and protrusions into each other and thereby forming serpentines 12 which form a fifth represented by the inner ring 3 guided flow channel.
- the Serpentine 12 are in communication with the axial bores 8. Through this serpentine-like cooling air flow is the residence time the cooling air in the inner ring 3 larger than the others described embodiments.
- the surface becomes for heat transfer (cooling) through the serpentines 12 increases and thus the effectiveness of cooling.
- Fig. 9 shows the cooling air flows a to h for the uncooled Variant of the inner ring 3 according to the prior art.
- a hot gas stream e from the Flow channel of the vane 1 in the annular gap between the Wickelichtung 4 and the labyrinth tips 5 is pulled and there leads to an increase in the leakage current f.
- FIGS. 10 and 11 illustrate the cooling air flows a to 1 for the cooled variant of the inner ring 3, wherein the cooling air flow k is low in FIG. 10 and large in FIG. 11.
- the amount the cooling air flow k can be controlled by a higher pressure of the Cooling air in the vane 1, a larger diameter of the Hole 7 or a change in the flow resistance through the design of the inlet and outlet (rounded, sharp-edged) change the hole 7.
- the cooling air flow k is a cooling air flow of small amount. It is observed that the Hot gas collapse e is avoided and a much lower Leakage flow f through the annular gap between the honeycomb seal 4th and the labyrinth tips 5 flows. The annular gap between the Wickelichtung 4 and the labyrinth tips 5 is in one Direction of the leakage flow f flows through.
