Abstract
The utility model discloses a turbine blade, which relates to the technical field of mechanical manufacture and solves the problem that wind energy delivered by the turbine blade in the prior art is hindered by air eddy to cause large gap loss among air flow and then reduce the output efficiency of the wind energy. The technical scheme provided by the utility model is as follows: air guide baffle braces which are uniformly and spirally distributed on the turbine blade are changed into air guide baffle braces which are uniformly and spirally distributed and alternated with long and short. With the adoption of the technical scheme, the gap loss among the air flow can be reduced by the air guide baffle braces on the turbine blade, and thus the conversion efficiency of air flow to kinetic energy is obviously improved.
Description
Technical field
The utility model relates to machinery manufacturing technology field, is a kind of turbine blade specifically.
Background technique
Turbo machine is widely used in each industrial field.In practical application, the rotating shaft of turbo machine is high speed rotating under the drive of motor, is installed with turbine blade in the rotating shaft of turbo machine, and turbine blade rotates around the shaft.Because turbine blade in the high speed rotating process, can produce air swirl.The wind energy that turbine blade of the prior art is carried receives the obstruction of air swirl, causes the wind-force delivery efficiency to reduce.Its main cause is the diaphragm lacing wire on the turbine blade, is even spiral and distributes, and this design causes the gap loss between the air-flow big, so the low defective of wind-force delivery efficiency.
Summary of the invention
The purpose of the utility model provides a kind of turbine blade, in order to solve the inefficient defective of turbine blade output wind-force in the existing technology.
For realizing above-mentioned purpose; The technological scheme of the utility model is a kind of turbine blade; Comprise the turbine blade main body, the diaphragm lacing wire, turbine blade is installed hoop; On said turbine blade main body, be provided with long and short alternately and be the diaphragm lacing wire that even spiral distributes, turbine blade is installed the neutral position of hoop in the turbine blade main body.
Because adopt above-mentioned technological scheme, the diaphragm lacing wire on such turbine blade has reduced the gap loss between the air-flow, the conversion efficiency that makes air-flow be transformed to kinetic energy significantly improves.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Indicate in the accompanying drawing 1: 1 turbine blade main body, 2 diaphragm lacing wires, 3 turbine blades are installed hoop.
Embodiment
On turbine blade main body 1, be provided with long and short alternate and be the diaphragm lacing wire 2 that even spiral distributes; Turbine blade is installed hoop 3 neutral positions in turbine blade main body 1; The place, axle center that turbine blade is installed hoop 3 is provided with mounting hole, is used for turbine is installed in main shaft.According to hydromechanical principle, air-flow gets into turbine blade, through the motion of the stream between the diaphragm lacing wire on the turbine blade, has the function that the air-flow of high pressure is transformed to kinetic energy.
The utility model with the diaphragm lacing wire that even spiral distributes that is on the turbine blade, changes over long and short diaphragm lacing wire alternate and that be even spiral distribution just according to this hydromechanical principle.Thereby the gap loss between the diaphragm lacing wire on the reduction turbine blade causes conversion efficiency to improve.
In the practical application of present embodiment, the rotating shaft of turbo machine is high speed rotating under the drive of motor, and turbine blade rotates around the shaft, produces air swirl.Diaphragm lacing wire on the turbine blade of the prior art is even spiral and distributes, and the wind energy that turbine blade is carried receives the obstruction of air swirl, causes the wind-force delivery efficiency to reduce.Its main cause is that the gap loss between the diaphragm lacing wire on the turbine blade reaches quite significant degree, thereby causes tangible loss in efficiency.The reason of this gap loss be on turbine blade diaphragm lacing wire outer end on the pressure side with the pressure difference of inner end suction side; The overflow of working air current appears; Move through the stream between the diaphragm lacing wire on the turbine blade; This overflow has increased the friction between the diaphragm lacing wire on the turbine blade, and the wind energy that turbine blade is carried receives the obstruction of air swirl, causes the wind-force delivery efficiency to reduce.The utility model changes over long and short diaphragm lacing wire alternate and that be even spiral distribution with the diaphragm lacing wire that even spiral distributes that is on the turbine blade.Thereby the gap loss between the diaphragm lacing wire on the reduction turbine blade makes efficient significantly improve.
Obviously, the foregoing description of the utility model only be for explain clearly that the utility model does for example, and be not to be qualification to the mode of execution of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here can't give exhaustive to all mode of executions.Conspicuous variation that every technological scheme that belongs to the utility model is extended out or change still are in the row of the protection domain of the utility model.
