To buy second-hand wind turbines, you can try the following methods:
1. Online second-hand trading platforms: such as eBay, Craiglist, Gumtree, etc. Second-hand wind turbines are often sold on these platforms Big windmill. You can search and contact sellers on these platforms to communicate and purchase.
2. Agricultural equipment market: In rural areas or agricultural equipment markets, some farmers or agricultural enterprises may sell second-hand wind turbines. You can go to your local agricultural equipment market to consult and find relevant information.
3. Recycling stations or scrap collection points: Sometimes some abandoned wind turbines may be purchased by recycling depots or scrap recycling points. You can consult your local recycling depot or scrap recycling point to see if There are used wind turbines available for purchase.
No matter which way you choose to buy a second-hand wind turbine, it is recommended to carefully check the condition of the equipment before purchasing to ensure that it is working properly and meets your needs. In addition, you also need to pay attention to the relevant regulations and safety matters for the installation and use of wind power generation equipment.
How much electricity can the wind turbine generate per hour?
It is recommended that you contact and communicate directly with the relevant departments of the Power Supply Bureau.
Because if your wind power is to be sent out, it will be directly connected to the power grid and you still need to contact and communicate with the power supply bureau. It is better to contact them directly now. They can also give you some suggestions or ideas.
Wish you a prosperous business!
The electric energy generated by each rotation of the wind energy generator is also different. For example, the most common 2MW direct-drive wind energy generator has sufficient and stable wind energy. The motor can generate 2,000 degrees of electricity every 60 minutes.
It takes 3.5 seconds for the fan blades to rotate once, and 60 minutes is 3600 seconds. Therefore, the amount of electricity generated by the generator per second is 0.56 degrees, so the amount of electricity generated by the wind energy generator fan for each revolution is The power generated is 0.56×3.5 seconds, which is 1.94 kilowatt-hours of electricity.
Extended informationBecause the wind volume is unstable, the wind turbine outputs alternating current of 13~25V, which must be rectified by the charger and then charge the battery to make the wind power The electrical energy produced by the generator is converted into chemical energy. Then use an inverter power supply with a protection circuit to convert the chemical energy in the battery into AC 220V mains power to ensure stable use.
Mechanical connection and power transmission: The horizontal axis fan blades are connected to the universal elastic coupling through the gearbox and its high-speed shaft to transmit the torque to the drive shaft of the generator. This coupling should be Has good damping and vibration absorption properties.
Performed by absorbing the appropriate amount of radial, axial and certain angular deflections, and the coupling can prevent the overload of the mechanical device. The other type is the direct-drive fan blades, which are directly connected to the motor without passing through the gearbox. Type of fan motor
