Let’s give praise and encouragement to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Great Development in Chemical Engineering Equipment】Regular updates and summaries are available – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** Recently, the turbine developed by Hangzhou Steam Turbine Group for 120,000-class air separation units completed a full-scale no-load operation test on the factory’s assembly and testing platform, with the test succeeding successfully from start to finish. All key performance indicators of the turbine met the required standards, and representatives of the customers witnessed this remarkable moment of domestic high-end power equipment in action! The key performance indicators are at their best levels. This no-load test represents a comprehensive assessment of the quality throughout the entire process of unit design, manufacturing, and assembly. During the testing process, the unit operated smoothly, with key performance indicators such as vibration and bearing temperature showing excellent results that far exceeded industry standards. This fully demonstrated the scientific design of the unit, the precision of its manufacturing, and the professionalism of its assembly, laying a solid foundation for the subsequent official operation of the unit. Multiple industry-related technical challenges have been overcome. The 120,000-class air separation turbine is a significant benchmark in China’s field of air separation turbines, representing the highest level of research, development, and manufacturing in this sector at home. This product features high individual power consumption, high requirements for operational efficiency, a complex overall structure, and strict controls on vibration levels; as a result, the research, development, and manufacturing processes face numerous technical challenges common to the industry. To develop this high-quality equipment, Hangzhou Steam Turbine Group established a dedicated technical team to focus on the key technical challenges. They carried out in-depth optimization of the flow layout structure, systematically improving the aerodynamic performance of the units. As a result, the design efficiency of these units under rated operating conditions reached an internationally leading level, thereby breaking foreign countries’ technological dominance in the field of ultra-large air separation steam turbines. Rigorous refinement throughout the entire process yields high-quality products. During the research and development phase, the project team adheres to the philosophy of creating high-quality projects while improving efficiency. By adopting modular and standardized design approaches, they develop standardized design solutions and system configurations, which not only reduces the amount of work required for customizations but also significantly shortens the R&D and manufacturing cycle, thereby enhancing both efficiency and quality. At the same time, the team takes full account of the thermal stress distribution, aerodynamic matching of flow, structural strength, stiffness, and vibration characteristics under varying operating conditions of the engine unit. By leveraging cutting-edge technologies such as numerical simulation analysis and lightweight design, it carries out scientific optimization of key components such as high-temperature heat-resistant parts and large-sized welded components, thereby enhancing the overall performance and long-term operational reliability of the entire system. During the final assembly phase, the assembly team works in close collaboration with the R&D and technical teams to identify key challenging processes and potential risk factors in advance, thereby continuously improving the assembly processes. The front-line staff worked overtime to overcome various challenges, including the difficulties associated with assembling large-sized components, the complexity of tuning out new designs, and tight delivery deadlines. They completed the entire process of unit assembly and testing to high standards and with strict requirements. Level breakthroughs to expand into global markets: The successful no-load test of this 120,000-class air separation turbine on the first attempt marks a significant technological advancement by Hangzhou Turbine Group in the research, development, and manufacturing of ultra-large, high-efficiency turbines for air separation applications. This breakthrough further strengthens the group’s leadership position in this industry, providing strong support and product assurance for the company to enter larger domestic and international air separation markets and capture a share of the market for high-end equipment.
