Few environmental pollution, it has also become the main development direction of current industry advanced country thermal power generating technology.
600MW level coal unit is the thermoelectricity main force unit of majority industrially developed country of the world, and the unit of this capacitance grade is also
The series greatly developed at present China's construction of fire and electricity, thermoelectricity either development to national economy, or living standards of the people
Improve, all play significant role.And novel 600MW steam turbine 193 high, medium and low voltage soldering blade, high, medium and low voltage
Blade carries out the optimization operation in structure to it, to improve its stability and economy again, improves production efficiency, cost-effective,
It is made more to adapt to the fired power generating unit requirement to it.
Utility model content
Utility model purpose: this utility model provides the high, medium and low voltage soldering blade of a kind of 600MW steam turbine, high, in,
Low pressure blade is made up of blade root, blade profile and shroud, and blade uses two panels group structure, and blade elder generation monolithic is processed, then two
Sheet blade soldering connects, and is effectively improved production efficiency, improves the features such as blade strength, makes 600MW steam-turbine unit have well
Stability and economy.
Technical scheme: the high, medium and low voltage soldering blade of a kind of 600MW steam turbine, is made up of blade root, blade profile and shroud, institute
Stating blade root cross section along its length is " work " shape, and described blade profile is complete three-dimensional bending blade profile, and described shroud is positioned at vane tip,
For integral (tip) shroud form；Described blade is that two panels one group is arranged side by side, and between described blade two panels, soldering connects.
Further, the fusing point fusing point less than described blade of solder is used between described blade two panels.
Beneficial effect: this utility model uses single blade profile, blade root, shroud composition integral form blade.The blade root of this kind of blade
Use " work " shape blade root, compared with vertical tree type blade root, process easier, it is simple to location and installation and effective.Blade profile uses

Moistening blade, fills play movement and is allowed to blade phase counterdiffusion weld with another sheet blade.It is effectively improved production efficiency, carries
The features such as high blade strength.The application of the type blade will improve the service life of 600MW steam turbine high, medium and low voltage blade,
Increase blade strength, make 600MW steam-turbine unit have good stability and economy.
The high, medium and low voltage soldering blade of a kind of 600MW steam turbine of the present utility model, has processing simplicity, it is easy to assembling,
It is easy to location and installation and effective.Blade uses two panels group structure, and blade elder generation monolithic is processed, and then uses ratio blade fusing point
Solder made by low metal material, by a piece of blade and solder heat to higher than solder fusing point, less than blade fusion temperature, utilizes liquid
State solder wetting blade, fills play movement and is allowed to blade phase counterdiffusion weld with another sheet blade.Answering of this Series Blade
With the service life of the high, medium and low voltage blade by improving 600MW steam turbine, increase blade strength, make 600MW steam turbine machine
Group has good stability and economy.Use the 600MW steam-turbine unit of this Series Blade, tie up during life-time service
Repair frequency substantially to reduce, 15 years overhaul lifes, greatly reduce maintenance cost.
