Description
Technical field
A kind of steam turbine stator is the utility model is related to, stator is turned to more particularly, to a kind of steam turbine high efficiency.
Background technology
Steam turbine blade is mounted on turbine rotor, and produces moment of torsion under the vapor action of HTHP, is made
The important component of turbine rotor high-speed rotation.Chinese patent discloses a kind of final stage moving blade of feed pump industrial steam turbine
（Publication number：CN106256993A）, a kind of final stage moving blade of feed pump industrial steam turbine, including be sequentially connected blade root,
Blade and for making blade form the shroud of whole circle self-locking, blade is provided with lacing wire boss, and the molded line of blade is variable cross-section distortion type
Line, have relative torsion between the two neighboring section of blade, along blade root to shroud short transverse, with blade with respect to the high H of leaf by
0% monotonicallys increase up to 100%, and the pitch to chord length in tea residue section to leaf top section is than T/b changing rule：0.2≤T/b≤
1.0, the pitch from tea residue section to leaf top section is than T/B changing rule with blade profile section axial width：0.2≤T/B≤
4.0；Pitch from tea residue section to leaf top section is than T/Dmax changing rule with blade profile section maximum gauge：2.4≤T/
Dmax≤17.6；Pitch from tea residue section to leaf top section is than T/A changing rule with blade profile area of section：0.02≤T/A
≤0.3；Blade profile leading-edge radius R0 changing rules from tea residue section to leaf top section are：1.6mm≤R0≤2.2mm；From tea residue
The blade profile trailing edge radius R1 changing rules of section to leaf top section are：0.7mm≤R1≤1.1mm.But this turbine blade
More it is not easy when in use because the impulsive force being subject to is larger, during steering, wearability is poor, and water conservancy diversion is ineffective, therefore uses
Life-span is shorter, can not use in steam turbine turns to stator, production cost is higher.
Utility model content
The utility model is to provide a kind of steam turbine high efficiency and turns to stator, and it is mainly solved present in prior art
Turbine blade is larger due to the impulsive force received when in use, is more not easy during steering, wearability is poor, and water conservancy diversion effect is not
It is good, therefore service life is shorter, can not use in steam turbine turns to stator, the technical problem of the higher grade of production cost.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：
Steam turbine high efficiency of the present utility model turns to stator, including stator body, is set at the top of described stator body
There is connector, the neck of connector is provided with groove, and the outer surface of stator body is provided with into vapour intrados, enters vapour intrados indent simultaneously
And entirety is in echelon, stator body integrally bending camber.Connector can be used for each guide vane and first stator, last stator
It is fixed together, ensures the fastness of connection, set groove that material therefor can be greatly decreased, saves production cost.Enter in vapour
Cambered surface can be directed into vapour, bear the high temperature and high pressure steam that nozzle is come in, and make steam by changing steam flow direction with more preferable
Angle enters first order movable vane piece to increase the whole efficiency of steam turbine.
Preferably, the described outer surface for entering vapour intrados is provided with some water conservancy diversion fins, water conservancy diversion fin spirality row
Cloth.Steam flow can be guided, increased into vapour efficiency by water conservancy diversion fin.
Preferably, being provided with zigzag caulking groove at the described edge air intake for entering vapour intrados, it is embedded with caulking groove
Strengthen alloy-layer.Set and strengthen alloy-layer, it is ensured that enter abrasion-resistance during vapour, increase the service life.Strengthening alloy-layer can
To be made of commercially available high-abrasive material.
Preferably, the side of described stator body is inclined-plane, the angle α of itself and vertical plane is 5-10 °.Inclined-plane is set
Vapour can be preferably directed into, angle α most preferably can be 8 °.
Therefore, the blade angle that the utility model is set is best angle, and using strengthening alloy-layer so that steering is led
The erosion that leaf is subject to when rotated is smaller, and it is higher to enter vapour efficiency, therefore service life is longer, and production cost is relatively low, simple in construction,
Rationally.
