Example Embodiment
[0026] Such as figure 2 , image 3 with Figure 4 As shown, a high-temperature axial-flow exhaust gas turbine adopts an axial intake and radial upward or downward exhaust structure, including an intake housing 1, a primary guide vane 2, a secondary guide vane 3, Rotor 4, transition housing [20], exhaust casing 5, bearing system 6 and base 7.
[0027] Moving blades are installed on the rotor 4;
[0028] Each leaf of the moving blade includes a leaf crown 14, a leaf body [18] and a leaf root 15. Each leaf crown 14 has a V-shaped structure.
[0029] The bucket includes a primary bucket 12 and a secondary bucket 13.
[0030] The tip shroud of the rotor blade adopts a honeycomb seal with a complete ring structure. Specifically, the outer side of the first-level rotor blade 12 is the first-level rotor honeycomb seal 8, and the outer side of the second-level rotor blade 13 is the second-level rotor. Leaf honeycomb seal 9.
[0031] When the blades of the entire stage of the moving blades ar...
