火电厂汽轮机大修关键节点管理与质量控制

摘要

在火电厂中，汽轮机作为核心设备，其运行效能直接左右发电效率与供电稳定性。长期运行下，汽轮机部件受多种因素影响，磨损、腐蚀问题频发，严重威胁设备正常运转。故而，定期大修成为保障汽轮机持续可靠运行的必要手段。然而，大修流程繁杂，涵盖众多关键节点，对其管理与质量控制极为关键。本文深入剖析汽轮机大修关键节点管理流程，从准备、拆解、维修到安装调试各环节，结合质量控制体系构建、过程监督及验收管理等内容，阐述如何保障大修质量，提升设备性能，为火电厂安全高效生产筑牢根基。

Abstract

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.
