Wind turbine components can be divided into blade systems, power systems, transmission systems and control systems. The main components are: blades, gearboxes, generators, hubs, spindles, electronic control systems, towers and so on. Among all the components, the four components of the blade, the hub, the gearbox and the generator account for 50% of the total cost. Due to the high technical requirements of the above components, the imported products are mainly used, but domestic manufacturers have begun production.
Let us know in detail the main components of wind power equipment and their production:
First, the blade: the material is glass fiber reinforced resin and carbon fiber. As the capacity of the wind turbine unit continues to increase, the length of the required blades increases, and the manufacturing difficulty increases. The megawatt blade is currently a relatively tight supply of components.
Second, the hub: cast by cast iron in the low temperature of minus 40 degrees Celsius, is the part that connects the blade to the main shaft. The wind turbine has high requirements on the fatigue resistance of the hub under low temperature conditions.
3. Bearings: The most scarce parts in the wind power equipment industry. The bearings required by domestic wind turbine manufacturers are mainly from SKF in Sweden, Schaeffler in Germany and Timken in the United States. Domestic enterprises have begun to develop wind turbine bearings, but due to product quality concerns, wind power equipment companies have not applied a large number of domestic bearings.
Fourth, the gearbox: an important part of the variable speed constant frequency doubly-fed wind turbine. The wind turbine has high requirements on the quality of the gearbox. If the fault occurs and the maintenance cost is high, the imported gearbox is often used in domestic fans. The domestic enterprises that can produce wind power gearboxes include Nanjing High Speed ​​Gearbox Factory, Chongqing Gearbox Factory and Hangzhou Gearbox Factory.
5. Generators: Technical barriers are relatively low. Domestic manufacturers can now produce high-end products such as 1.5MW variable-speed constant-frequency generators and 2MW direct-drive permanent-magnet generators.
Sixth, wind power tower: also known as tower, used to support the entire wind turbine, is the main load-bearing object of the wind turbine, the load bearing includes wind load, unit weight and eccentric moment caused by the center of gravity of the unit, etc. It is a truncated cone type, which is composed of multiple sections. Each section is flanged and the material is mostly Q345B steel.
