摘　　要：汽轮机同轴驱动泵是一种相对简化的锅炉给水设备。针对国内首台660 MW机组汽轮机调速之星同轴给水泵的启动及调试过程中遇到的问题,进行详细了的描述,并提出了解决方案。主要介绍了调速之星的设备功能、工作原理、系统结构、试运过程及运行中影响设备系统安全的隐患。重点对调速之星及同轴给水泵空负荷启动、带负荷试运、满负荷运行及重大试验过程中的控制要点,以及汽轮机、同轴给水泵、调速之星之间的相互控制逻辑进行了详细说明;对系统设备运行过程中存在的问题也提出了明确的建议和意见,通过调整启动参数、优化控制方式、修改DEH逻辑以及细化运行操作等措施,逐一解决系统试运过程中的各种问题,从而完成汽轮机同轴给水泵带负荷及满负荷连续试运的过程,为同类型新建机组同轴给水泵的启动调试提供了借鉴。The steam turbine coaxial drive pump is a kind of relatively simplified boiler water supply equipment. The problems in the start-up and commissioning of the first 660MW steam turbine speed governing star coaxial feed water pump are described in detail, and the solutions are put forward the function, working principle, system structure, trial operation process and hidden trouble affecting the safety of the equipment system of speed regulating star is introduced. Focus on the speed control star and coaxial feed pump start-up, load test, full load operation and major test process control points, the mutual control logic among the steam turbine, the coaxial feed water pump and the speed regulating star is explained in detail, by adjusting the start-up parameters, optimizing the control mode, modifying the DEH logic and refining the operation, the various problems in the trial operation of the system are solved one by one. Thus, the process of continuous trial operation of coaxial feed pump with load and full load of steam turbine can be completed.
