The yoke forgings disc manufactured by SDYL Energy Equipment Tech Group, a large-scale disc, ring, cylinder, module forging and special-shaped forging manufacturer in China, are shipped to the world's largest pumped storage power station-Fengning Pumped Storage Power Station.
The yoke forging is an important structural part for fixing the magnetic pole and an important part of the entire magnetic circuit. It will be installed at the most core position of the generator motor unit. Due to the huge centrifugal force generated when the generator motor rotates, these centrifugal forces are mainly borne by the body of the yoke forging, so the quality requirements of the yoke forging are also very high. At -30 ℃, the tensile strength is ≥800MPa and the yield strength is ≥700MPa.
SDYL uses radial and axial integral rolling technology to manufacture yoke forgings, which breaks through the limitation of the opening space of traditional free forging presses on the size of forgings, improves the processing and installation accuracy of yoke components, and ensures good overall rigidity of yoke components. Successfully solved the problems of looseness and shrinkage of current cast steel yoke parts, deformation and wrong teeth of steel plate splice yoke parts.
Since 2019, SDYL has also provided various forgings such as ring plates, magnetic yoke discs, top cover flanges and other projects for Heilongjiang Huangou Pumped Storage Power Station and Guangdong Yangjiang Pumped Storage Power Station.
About Fengning Pumped Storage Power Station. The Fengning Pumped Storage Power Station is a key green energy project supporting the 2022 Beijing Winter Olympics and is used to provide power guarantee for various events during the Winter Olympics. After the project is completed, the annual power generation can reach 6.6 billion kWh, which is equivalent to saving 480,000 tons of standard coal, which is of great significance for achieving the 100% clean energy power supply promised by the Beijing Olympic Winter Games. After the completion of the first and second phases of the Fengning project, it will become the world's largest pumped storage power station with an installed capacity of 3,600 MW.
At present, the conversion rate of electric energy of large pumped storage power stations can reach an astonishing 75% -85%, while the conversion rate of our commonly used mobile phone charging treasure is only about 65%. Fengning Pumped Storage Power Station uses reversible generator motors (motors when pumping, which quickly become generators during power generation), and the pumping-generation state transition takes less than 5 minutes. When a large-scale power outage occurs in the power grid, the pumped storage power station does not need any external power, and only needs to "open the gate to release water" to instantly generate electricity and wake up the power grid. Fengning Pumped Storage Power Station will undertake the important tasks of peak shaving, valley filling and emergency response throughout the Beijing-Tianjin-Hebei power grid.
