On November 16, at 2:28 pm, the steam turbine generator set of Unit 3 of Huadian Wuhu Phase II Project constructed by China Power Construction Anhui Electricity Construction Company was successfully installed, laying a solid foundation for the subsequent installation of steam turbine main body.
The project No. 3 turbine turbo generator stator length of 11.8 meters, 5.2 meters wide, 4.7 meters high, net weight of 409 tons, is the heaviest single unit of the entire project.To successfully complete the lifting tasks, China can build Anhui Power Build a company to take the initiative to communicate with the owners, supervisors, according to the arrival of the stator, hoisting plan developed in advance planning, and the relevant parties to conduct joint review of the hoisting of the two vehicles installed in the engine room hanging suspension system Lifting in place of the program.After the layout of a complete lifting system, the project department involved in the lifting of machinery and equipment were strictly checked and accepted, all the operators conducted a safety test.
7:58 on the same day, together with the preparation work is ready, along with the instructions of the lifting command, the generator stator in the two traffic lift, slowly raised to 2 meters, do static load test ten minutes, Lifting technicians check lifting wire rope force, driving lag, brake performance, etc. After confirming the accuracy is correct, continue to upgrade.When the height of the stator lifting more than 17 meters layer platform 5 meters, the hydraulic lifting device to stop lifting, lifting personnel Command the two cars to move to the stator base direction.When the stator is fully into the 17 meter platform, the car stops moving, use the hook to rotate the generator stator 90 degrees, and continue to the stator base direction until the stator reaches the foundation just above , The operation of hydraulic lifting device descend the strand to the stator landed on the base plate, to find the right place finally, after all the operators more than six hours of meticulous cooperation, under the witness of the owners, supervisors, Unit 3 Generator stator hoisted in place.
Huadian Wuhu Power Plant Phase II plans to build two 1 million kilowatt-class ultra-supercritical clean high-efficiency coal-fired generating units were included in Anhui Province 'Thirteen Five' major construction project library, first to build a Taiwan with an investment of 3.92 billion yuan. The project follows the concept of "leading indicators and advanced environmental protection", and adopts high-parameter energy-saving technologies. At the same time, advanced technologies such as low-temperature electric dust removal, high-efficiency desulfurization and dust removal integration, digitized coal yard and deep waste heat utilization of flue gas are adopted, Leading Unit 3 is scheduled to be completed and put into operation in August 2018. Put into operation, for the strengthening of southern Anhui power supply capacity, improve the reliability of power security and promote local economic development of great significance.
