In June 2010, Dongfang Electric New Energy Co., Ltd. began to independently design, research and develop and manufacture large-scale onshore new-generation permanent magnet direct-drive wind turbines with completely independent intellectual property rights according to market demand. After a year and a half, the first 2.5 MW permanent magnet direct drive wind turbine was successfully launched. The center of the fan hub is 80 meters high and the diameter of the wind wheel is 103 meters. It adopts direct drive + permanent magnet synchronous motor + full power converter technology, which is suitable for the second and third types of wind farms on the land, and continues the advantages of direct drive permanent magnet technology. Innovate and optimize the product structure design and electronic control system, compared with most wind turbines of the same capacity on the market, on the basis of better performance, lighter weight, power generation efficiency, reliability, grid adaptability, etc. Excellent performance on key indicators, in the future, in the installation, transportation, hoisting, maintenance and other aspects, will also reflect better performance value and economic indicators.
Dongfang Electric Co., Ltd., the parent company of Dongfang Electric New Energy Co., Ltd., as a large state-owned enterprise in China's power generation equipment manufacturing, has accumulated considerable technical strength in the research and development and manufacture of power generation equipment. To this end, Dongfang New Energy Company has established a development route with international cooperation, high starting point and sustainable development in combination with the development trend of wind power technology and the advantages and characteristics of Dongfang Electric. Especially in the technical route, the new energy company has chosen a direct-drive wind turbine that represents high reliability and high power generation. It cooperates with the famous wind power design technology company in Europe and combines with the world's most advanced design concepts and design methods. The successful development of the Oriental 1.5 MW direct-drive wind turbine has been mass-produced and passed the A-level design evaluation and type certification of the internationally renowned certification company TüV SÜD in accordance with the GL guidelines. Liu Hui, secretary of the Party Committee of Dongfang Electric, said that the downline of the 2.5 MW direct-drive wind turbine is of great significance for the development of Dongfang New Energy Company. The future 2 MW to 3 MW units will be the main models of the onshore wind turbine market. The downline of the new energy company's 2.5 MW direct-drive wind turbine enriches the company's product line and will effectively enhance its competitiveness. According to reports, Dongfang Electric New Energy Co., Ltd. will gradually introduce 6 MW, 10 MW and other wind turbines with higher power, more adaptability and more advanced technology, bringing more and better choices to the market and users.
1. Welding Machines - A welding machine is an essential tool for any welding job. It is used to create a welding arc that melts the metal being joined, allowing it to fuse together.
2. Welding Electrodes - Welding electrodes are metal rods that are used to conduct electricity and create an arc. They are coated with a flux that helps to protect the weld from contamination and oxidation.
3. Welding Wire - Welding wire is used in the MIG welding process to feed the welding arc with a continuous supply of wire. It is available in different thicknesses and materials, such as stainless steel, aluminum, and mild steel.
4. Welding Helmets - Welding helmets are designed to protect the welder's eyes and face from the intense light and heat produced during welding. They come in different styles and designs, including auto-darkening helmets that automatically adjust to the brightness of the welding arc.
5. Welding Gloves - Welding gloves are used to protect the welder's hands from heat, sparks, and other hazards associated with welding. They are made from materials such as leather and Kevlar and come in different sizes and styles.
6. Welding Safety Glasses - Welding safety glasses are designed to protect the welder's eyes from the intense light and UV radiation produced during welding. They are available in different shades and styles.
7. Welding Filler Metals - Welding filler metals are used to add material to the weld joint to create a strong, durable bond. They come in different materials, such as stainless steel, aluminum, and bronze.
8. Welding Clamps - Welding clamps are used to hold the metal being welded in place during the welding process. They come in different sizes and styles, including C-clamps, locking pliers, and magnetic clamps.
9. Welding Flux - Welding flux is used to protect the weld from contamination and oxidation during the welding process. It is available in different types, including powder, paste, and liquid.
10. Welding Gas - Welding gas is used in the TIG and MIG welding processes to shield the welding arc from contamination and oxidation. It is available in different types, including argon, helium, and carbon dioxide.
