Description
Technical field
The present invention relates to technical field of temperature control in wind generator unit wheel hub, and in particular to a kind of wind power generating set
Wheel hub temperature control equipment.
Background technology
Wind power generating set is to convert wind energy into a kind of device of electric energy, is typically made up of tower, cabin and wind wheel, tower
Cylinder is generally used for supporting cabin to high-altitude.Wind wheel part mainly includes blade, wheel hub, kuppe, variable blade control system etc..
Wind wheel structure is double-decker in form, and outer layer is kuppe, and it, which is acted on, mainly prevents wind and rain, sand and dust and air-flow from entering inlet air
Wheel is internal, and the parts in wind wheel are adversely affected.Internal layer is wheel hub, is thick and heavy metal level, and it, which is acted on, mainly holds
By the load of blade and whole wind wheel.The related components of variable blade control system are also typically mounted to hub inner lumen.When unit is transported
During row, the related components of variable blade control system, which can give off heat, accumulates in hub inner lumen, causes hub inner lumen temperature to raise, respectively
Parts overtemperature, finally forces compressor emergency shutdown.
The mainstream technology for solving each parts overtemperatute in wheel hub both at home and abroad at present mainly has three kinds.
1st, air holes is opened on wheel hub wall, is forced outside the air and wheel hub of hub inner lumen（Between kuppe and wheel hub）Formed
Circulate, when hot-air flow to position between wheel hub and kuppe, heat is passed to by the external world by kuppe heat conduction.Heat
The temperature of air is again introduced into hub inner lumen circulation after reducing, to reach temperature in control hub inner lumen, so as to solve parts
The purpose of overtemperatute.But because kuppe is generally glass steel material, thermal conductivity factor is relatively low, and the limited area of kuppe,
Cause heat output limited, so it is difficult to the control of hub inner lumen temperature is arrived into lower temperature.Although the program can be to a certain extent
Solve parts overtemperatute, but parts are still run under comparative high temperature environment, to the performance requirement phase of parts
To higher, simultaneously because running at relatively high temperatures, accelerate parts aging, shorten parts service life.
2nd, the perforate on kuppe, makes cool ambient air directly be skimmed over from hub outer wall, passes through the high heat conduction of metal wheel hub
The heat transfer of hub inner lumen into outside air, or is directly introduced external air into hub inner lumen by coefficient.Although the program
The temperature of hub inner lumen can be controlled in lower temperature, but in this scenario, the purpose of kuppe is used for the purpose of preventing rainwater
Into hub inner lumen, and will even be drenched with rain by wind for a long time for the parts in non-hub inner chamber, therefore for this
The corrosion resistance of parts thereof requires very high.In addition, the program is difficult to avoid sand and dust and salt fog to each zero in whole wind wheel
The influence of part.
3rd, the grade of each parts high temperature resistance service ability in wind wheel is improved, to improve each parts self performance grade
It is required that to solve overtemperatute.The program undoubtedly can solve parts overtemperatute, but and can not select versatility
Industrial part, while the performance rate of parts is improved, the cost of parts is set also to increase at double.
In view of this, it is special to propose the present invention.
The content of the invention
