The blades of the wind turbine do not rotate, what is the reason?

Introduction The blades of the wind turbine do not rotate. What is the reason why the owner's wind turbine does not rotate in strong winds? The situation is as follows: 1. Check the three-phase AC line of the generator.

The blades of the wind turbine do not rotate, what is the reason?

If the poster's wind turbine does not turn in strong winds, the following may be the problem:

1. Check whether the three-phase AC line of the generator is short-circuited

2 .Whether the fan blades are installed backwards

3. Whether the motor is burned out

4. Problems with the bearings

Problems with the other two fans of the original poster:< /p>

When people feel no wind on the ground but the blades rotate very fast, this is normal, because people on the ground certainly feel there is no wind, and when the fan is several meters high, the direction of the wind is different. The main thing is to see if the leaves are moving. If the leaves are obviously windy, it is normal for the fan to rotate so slowly, but the other one does not rotate. How far is the distance between the two units? If it is too close, it is normal. Because two units cannot be installed too close to each other, as this will affect its overall effect. In addition, the landlord should be aware that there should be no high-rise buildings around when installing the fan, and it is best to install it in an open area.

Based on these situations, please check if the above situation exists

What is the twisting angle of the twisted blades of the fan

Usually, there are two screws on the hub of the impeller. For M10 or M12 process holes, process an iron plate of 12mm or more, drill two holes according to the distance between the process holes, and weld a nut of M24 or above through the iron plate at the center of the iron plate and match it with a screw. The screw is in contact with the shaft end of the fan. Process it into a cone, push it onto the center hole of the fan shaft, and rotate the screw to pull out the impeller.

The twist angle of the fan blades is determined based on the wind pressure and air volume requirements of the fan design. If the wind pressure requirement is large, the power requirement will be large, but the air volume will be smaller. Of course, the angle of the fan can be 20°, 25°, 30°, the maximum is 35°. At this point I know you can choose the appropriate angle according to your needs.
