It connects the wind turbine unit and the generator set, playing the role of transmitting mechanical power and bearing torque. At the same time, it also plays a crucial role in the connection and fixation of components such as blades, generator hubs, and tower barrels, enabling the wind turbine unit to operate smoothly in the natural environment. Types Tower barrel flange: It is used to connect each section of the tower barrel of the wind turbine generator set. Usually, it has a large diameter and heavy weight, and it is necessary to consider its ability to bear the load of the wind turbine tower barrel and its anti-fatigue performance. Hub flange: It connects the hub and the top of the tower barrel. It needs to bear the thrust and bending moment from the wind wheel, and has high requirements for strength and stiffness. Blade flange: It is used to connect the root of the blade to the hub. Its size is relatively small, but it requires a high degree of precision to ensure the correct installation angle of the blade and the efficient operation of the wind turbine. Tower foundation flange: It connects the tower foundation and the tower barrel, mainly bearing the wind turbine itself and the effect of the wind force. It has seismic performance and corrosion resistance. Generator flange: It connects the generator and the blade shaft, mainly bearing the weight of the generator and the received rotational torque, and has high strength and high stiffness. Pitch frame flange: It connects the pitch frame and the blade shaft, mainly controlling the angle and rotation speed of the blade, and has a precise and stable adjustment effect. Assembly fitting flange: It is used to connect equipment such as pipelines, valves, and pumps inside the wind turbine, and has the characteristics of good sealing performance and easy installation. Features High strength: It needs to withstand the influence of wind force and rotational torque, and should have high strength and stiffness to ensure safe and reliable operation. Strong corrosion resistance: Since wind turbine generator sets are often installed in marine or storm-prone areas, wind power flanges need to have good corrosion resistance and be able to resist the erosion of environmental factors such as seawater and climate. Firm connection: It is usually fastened and connected by bolts to ensure a firm connection between the wind turbine impeller and the main shaft, and at the same time, it can bear a large amount of torque and vibration. Good lubricity: Regular lubrication and maintenance are usually required to reduce friction and wear and maintain a good working state under high-speed rotation and harsh environmental conditions. Detachability: For the convenience of maintenance and replacement of components, it is usually designed as a detachable structure, which can be quickly disassembled and installed. Good anti-fatigue performance: Since wind turbine generator sets need to operate continuously for a long time, wind power flanges need to have good anti-fatigue performance and be able to withstand frequently fluctuating loads. Materials Steel: It is one of the main raw materials. Commonly used steels include carbon steel, alloy steel, and stainless steel, etc. Carbon steel has good mechanical properties and workability; alloy steel has high strength and wear resistance; stainless steel has excellent corrosion resistance and high aesthetic degree. Cast iron: It has high strength and toughness, low cost, and can be produced through the casting process. It is often used to make the main body of large wind power flanges. Aluminum alloy: It is light in weight, has good corrosion resistance and thermal conductivity, and is often used to make small wind power flanges, suitable for environments where weight and size are limited. Polymer materials: Such as polypropylene, polyurethane, etc., have good corrosion resistance, insulation performance, and anti-fatigue performance, and can be used for some wind power flanges in special environments or with low weight requirements. Production Processes Forging: Forged flanges have high mechanical properties, dense structure, and reliable quality, but the cost is also high. Casting: It is suitable for flanges with complex shapes and large sizes. The cost is low, but there may be internal defects, and the strength and sealing performance are relatively poor. Cutting: Directly cut out a disc with the inner and outer diameters and thickness, leaving a machining allowance, of the flange on the medium plate, and then process the bolt holes and water lines. The flatness is good, and the quality can meet general requirements. Rolling: Cut the medium plate into strips, roll and process them into a circular welded joint, then use the flattening process for processing, and then process the water lines, spigot joints, bolt holes, etc. The cost is relatively low, and it is often used in the production of large flanges. Development Status With the acceleration of the pace of energy low-carbon transformation, the number of large-scale onshore and offshore wind power projects is increasing day by day, and the demand for wind power flanges is also continuously increasing. At present, some enterprises have achieved the intelligent and high-precision processing of wind power flange production, and are able to produce various types and specifications of flange components to meet the needs of different wind power projects.
