In thermal power plants, steam turbines are the core equipment, and their operational efficiency directly affects the power generation efficiency and power supply stability. Under long-term operation, turbine components are affected by various factors, resulting in frequent wear and corrosion problems, which seriously threaten the normal operation of the equipment. Therefore, regular major repairs have become a necessary means to ensure the continuous and reliable operation of steam turbines. However, the overhaul process is complex and covers numerous key nodes, making its management and quality control extremely critical. This article deeply analyzes the management process of key nodes in steam turbine overhaul, from preparation, disassembly, maintenance to installation and commissioning. Combining with the construction of quality control system, process supervision and acceptance management, it elaborates on how to ensure the quality of overhaul, improve equipment performance, and lay a solid foundation for safe and efficient production in thermal power plants.
