If you use it as a charger, please connect a diode in series to one end of the output line. If you use it as lighting, it only needs a drive motor to rotate.
The driving method can be tap water, bicycle, hand wind, etc. Wait, I suggest you use tap water to inject the tap water holes into the fan blades. If you want to succeed, buy some thermal glue and make a box to enclose. the water flow. It will be perfect.
Generator cooling water pressure Normally, if the flow rate suddenly decreases, the cause should be identified immediately if air enters the generator rotor, causing a decrease in the flow and input. the water pressure increases, the generator must be decoupled and the speed must be reduced to release the air. However, unit vibrations should be closely monitored. If vibrationsIf abnormalities occur, they should be treated according to the abnormal vibration treatment method. .
