WIND MILL 2000W 96V+STAND Small Wind Turbine: Descriptions: Traditional small wind generator at high speed(tail protection type),requires to fold the tail or yaw so that to control the SWT rotating speed. The normal SWT tail working method is folding in a Right Left direction; when the wind speed is too high, the tail can t response immediately affected by the tail rod length, the tail service area and the rod angle; What s worse, the tail cannot return back at the time that the SWT RPM is controlled. Such problems directly have affect on the SWT efficiency, cannot maximize the utilization of wind power. The tail keep folding all the time, its mechanical stabilization efficiency will be badly affected. Some time lately after installation, the tail would occur breakdown, may result with danger for the people. Because of the structure design loophole, the traditional SWT and its tail cannot be completely sealed, cannot get over water seepage problem and stop from dust erosion, the safety protection Grade is badly lowered. During practical application, traditional tail SWT, both its tail axle and axle sleeve will be worn down to different extend, affect SWT s service efficiency, most importantly it may result the tail with function loss and the generator burnt up under over wind speed.
MAX Nature Green Energy Limited after one year experiments and study invents a totally new tail design for SWT. As known to all, the tail s working principle is from aerodynamics, simply speaking, as the wind blows the SWT blades moving, back the blades forms eddy pressure, the tail will automatically rotate according to the pressure size. By the way reducing the blades windward area to decrease the wind power for the blades, its rotation speed can automatically reach to a reasonable speed that keep it and the SWG at a high efficiency service speed. We have named the new structure SWT as SWT with Rotating Shaft Tail. By our deep study and test, SWT with rotating shaft tail can achieve omniseal, equipped with mature standard bearing, using waterproof seal ring between every connection unit to stop from dusts, water, salt fog etc. The tail service principle is gravity, will not be affected by service time, normal wear or etc. Its operating point is comparatively unalterable, and its work stabilization well improved. SWT with rotating shaft tail during actual work, benefited from our unique technical innovation, the only mobile part is the tail s horizontal axial rotation, maximum working angle is 90, almost zero vibration. We have applied for patent protection for this technology. Advantages: 1.Wind wheel structure is simple and clear,hub adopts the mature fixed pitch structure,no complex mobile mechanical devices, extremely low failure rate and maintenance free. 2.All replacement parts are National Standard, can be easily found in oversea market. 3.Electric conduction device uses 3phase transmission slip ring, getting rid of twist cable risk. 4.No direct diving mechanism requirement for the revolving body s vertical axle, just the standard bearing; this structure easily solves the shaking problem caused by unstable airflow, in favor of improving the SWG s service life.
5.Unique and simple control mode, automatically wind warding, the SWT s work efficiency well increased. Make the best use of aerodynamics design, ensure the SWT working at safe wind speed and automatically deflexing 90 angle, totally avoiding windward if the wind is over high. The tail rotating method is patented; when the control system disabled, itself rotation axle can keep the SWT safe away from breakdown. Triple Protection, Away from Faults.
