PROBLEM TO BE SOLVED: To provide a shaft seal mechanism and a turbine equipped with the shaft seal mechanism capable of suppressing the wear of a brush and a rotating shaft while reducing the leakage quantity of gas from the high pressure side to the low pressure side.
SOLUTION: A brush seal 25 adopted in this shaft seal mechanism has a recessed part 31 formed on the inner peripheral surface of a stationary blade 24a; A ring 26 comprising a plurality of divided bodies formed in annular shape and disposed in the recessed part 31; the brush 28 formed of a large number of wires inserted in the inner periphery of the ring 26; plate springs 27a, 27b energizing the ring 26 in a separating direction from the rotating shaft 23 to lift the brush 28 from the peripheral surface 23a; and a lead hole 38 for leading fluid pressure for bringing the brush 28 into contact with the peripheral surface 23a by pressing the ring 26 in an approaching direction to the rotating shaft 23 against the energizing force of the plate springs 27a, 27b. Constitution provided with the brush seal 25 is adopted to the turbine.

<P>PROBLEM TO BE SOLVED: To provide structure for separating high pressure and low pressure turboexpanders of a gas turbine. <P>SOLUTION: This structure includes a diaphragm 31, a pair of shaped plates 50' and 50", a seal ring 60. The diaphragm 31 has a function to supply a flow of cooling air. The pair of shaped plates 50' and 50" are fixed on the diaphragm 31 and form a gap 52 to which the cooling air extracted from a turbocompressor 11 and supplied to a high temperature area of a turboexpander is blown. The seal ring 60 supported by the shaped plates 50' and 50", is designed to separate a high pressure 12 turboexpander and a low pressure 13 turboexpander and distribute the cooling air obtained from the gap 52. <P>COPYRIGHT: (C)2003,JPO |

PURPOSE: To obtain a braided filamentary sealing element having improved shape.dimension restorability, improved compliance and improved elastic modulus by arranging a plurality of three dimensionally braided filamentary sealing surfaces for engaging with other parts on sealing portions placed in a clearance space.
CONSTITUTION: This three dimensionally braided filamentary sealing element 30 has an outside portion 30a received in a support plate 40 and an inside portion 30b disposed in a clearance space S in a state faced to a circular rotor flange 20. The inside sealing portion 30b is formed from a plurality of densely braided filaments 60, has a free length L toward the rotor flange 20, and has a free end 60a cut on a flat surface PP.

PURPOSE:To enable the replacement of a sealing plug by a method wherein the sealing plug is inserted into a hole formed at a horizontal coupling surface of turbine casing and then the sealing plug is crossed at a right angle with a vertical coupling surface. CONSTITUTION:A hole for sealing plug is formed on a horizontal coupling surface, a sealing plug 5 is inserted at the end surface D of the discharging chamber and arranged in such a way as it may be crossed with a vertical coupling surface. Then, inserts 6, 7 are fixed to the discharging chambers 3, 4 by a welding at 8. In case of a replacement of the sealing plug 5, at first the inserts 6, 7 are removed and the sealing plug is replaced. |

PURPOSE:To facilitate the replacement work of sleeve, by threadably engaging a sleeve having the same outer diameter as that of rotor with the part of rotor opposing against a labyrinth packing. CONSTITUTION:An external thread formed at the part of turbine rotor 22 opposing against a labyrinth packing is engaged an internal thread formed around the inner periphery of sleeve 23 having the same outer diameter as that of rotor 22. Annular recesses 22b, 23b are projected from an area where the rotor 22 and the sleeve 23 contact each other at their side surfaces, and then a common annular sealing member 25 is inserted into these recesses. |

PURPOSE:To improve the sealing performance of a shank section by providing a seal plate with a degree of freedom for relative movements in the peripheral and axial directions of the shank between the shank sections of a turbine moving blade. CONSTITUTION:An H-shaped seal plate 19 is inserted between shank 3 sections of turbine moving blades 2 adjoining in the peripheral direction. Since individual lugs 19a protruding in four directions of the seal plate 19 have spring forces in the directions to press the sides of a groove 10, a sufficient seal performance can be assured. Furthermore, even if both adjacent shanks 3 moves relatively in the axial direction, the seal plate 19 rotates because the outside faces of individual lugs 19a are formed in an arc, and no gap is generated between the seal plate 19 and the side faces of the groove 10, thereby a sufficient sealing property can be assured. Accordingly, the sealing property of the shank section can be improved. |
