Features: This textbook is compiled in accordance with the requirements of the "Occupational Skill Identification Specification for the Power Industry of the People's Republic of China" for the vocational skill training of power generation. The textbook highlights practical operational skills as the main focus, closely integrating relevant professional theory with production practice. It reflects the current level of power generation technology development in China and embodies the principle of serving production realities and enterprises. The textbook is basically organized into volumes based on the "Specification" for the operation and maintenance of power generation. The entire set consists of 15 volumes, covering the vocational skill training of nearly 40 related job categories in the "Specification." For the key and difficult points in the textbook, supplementary "Review Questions and Solutions" will be published for each volume. The authors and reviewers of this textbook are technical personnel who have worked long-term in production lines, possessing a solid theoretical foundation and extensive practical and training experience. This volume is part of the "Power Generation," covering training content for four job categories: main turbine overhaul, auxiliary turbine and maintenance, turbine speed regulation system maintenance, and pump maintenance. Main contents include: turbine maintenance management, disassembly and maintenance of high-pressure alloy steel bolts, cylinders, nozzle, diaphragm (static vanes), steam seals, rotor and shaft system maintenance, bearing maintenance, composition of the speed regulation system, composition of the safety system, intermediate reheat turbines, static characteristics and sluggishness, regulation system maintenance, defect analysis and handling of the speed regulation system, function and composition of the fuel supply system, power-frequency electro-hydraulic regulation system, turbine digital electro-hydraulic control system DEH, pump concepts, small pump examples, small pump maintenance, key and special items in pump maintenance, DC-type pump maintenance, Weil-type feedwater pumps, and maintenance of the 72LKXA-28.5 vertical circulating water pump. Vibration fault handling, mechanical seals, feedwater pump steam turbines, hydrostatic couplers, condensers, high- and low-pressure heaters, deaerators, and air extraction units. This textbook serves as the vocational skill identification training material for power generation and the on-site production technology training textbook for power generation. It can also be used for teaching purposes in technical schools for power generation professionals.
