Description
Technical field
The utility model relates to steam turbine accessory technical field, particularly relates to a kind of turbine blade.
Background technique
In existing steam turbine technology, Turbo-generator Set belongs to a very ripe generation technology, and it relies on heat energy to produce High Temperature High Pressure air, and is rotated by High Temperature High Pressure air driven turbine blade, and then realize power generation process, wherein turbine blade is the vitals of Turbo-generator Set.The turbine blade generally used on the market is at present generally that the shape by changing blade is increased work efficiency, but the shape difficulty of processing changing rear blade increases, and then processing cost also corresponding increase.
Model utility content
The purpose of this utility model is to propose a kind of turbine blade, can increase the ability capturing steam impringement power, improve the utilization ratio of steam.
For reaching this object, the utility model by the following technical solutions:
A kind of turbine blade, comprise blade face and blade root, described blade face comprises inner arc surface and exterior arc surface, bottom described inner arc surface upwards bottom five/mono-to inner arc surface upwards 1/3rd places be coarse focusing surface, described blade face long side direction is arranged with several apertures.
As preferably, described aperture is cone shape hole.
As preferably, described coarse focusing surface is in netted projection or groove, and it is made up of fibrous composite.
As preferably, bottom described inner arc surface, upwards 1/5th places are provided with stiffening rib, and described stiffening rib is arranged with the radian of inner arc surface.
The beneficial effects of the utility model:
The utility model, by arranging coarse focusing surface on blade face, can increase the ability capturing steam impringement power, improve the utilization ratio of steam; By arranging aperture on the long side direction of blade face, the steam being parallel to blades flows can be changed and flowing to, impact force being produced to blade, improves utilization ratio and the generating efficiency of steam; The load-carrying ability of blade is enhanced by arranging stiffening rib.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the turbine blade that the utility model embodiment provides;
Fig. 2 is the single structure schematic diagram of the turbine blade that the utility model embodiment provides.
In figure:
1, blade face; 2, blade root; 3, inner arc surface; 4, exterior arc surface; 5, coarse focusing surface; 6, aperture.
Embodiment
The technical solution of the utility model is further illustrated by embodiment below in conjunction with accompanying drawing.
The utility model provides a kind of turbine blade, it comprises blade face 1 and blade root 2, described blade face 1 comprises inner arc surface 3 and exterior arc surface 4, bottom described inner arc surface 3 upwards bottom five/mono-to inner arc surface 3 upwards 1/3rd places be coarse focusing surface 5, coarse focusing surface 5 can increase the ability capturing steam impringement power, improves the utilization ratio of steam; Described blade face 1 long side direction is arranged with several apertures 6.
In present embodiment, preferably, described aperture 6 is cone shape hole, and the steam being parallel to blades flows can be changed the flow direction by cone shape hole, produces impact force to blade.
In present embodiment, preferably, described coarse focusing surface 5 is for being netted projection or groove, and it is made up of fibrous composite.
In present embodiment, preferably, bottom described inner arc surface 3, upwards 1/5th places are provided with stiffening rib 7, and described stiffening rib 7 is arranged with the radian of inner arc surface 3, the load-carrying ability that stiffening rib enhances blade is set, provides the working life of whole steam turbine.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not by the restriction of above-mentioned mode of execution; what describe in above-mentioned mode of execution and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall within the scope of claimed the utility model, and claimed scope of the present utility model is defined by appending claims and equivalent thereof.
