福建仙游蓄能电站水泵水轮机结构设计
摘要
抽水蓄能电站在电网中担任填谷调峰的关键作用,对提高电网供电质量和电网灵活性有着十分重要的意义。安装在抽水蓄能电站的水泵水轮机,需要根据电网的调度在水轮机和水泵两种工况间转换运行,以此完成调频调峰等重要任务。由于水头高、转速高、容量大、运行工况复杂、起停频繁等特点,因而决定了水泵水轮机在结构上表现出独有的特征.
福建仙游蓄能水电厂从电站规模、机组容量及高水头水泵水轮机等方面而言,都是极具代表性的抽水蓄能电站。本次毕业设计就是以该电站为对象,通过查阅相关资料及水轮机设计手册,辅助以CAD绘图工具,对其混流式水泵水轮机结构进行设计,绘制了总装配图,导水机构装配图,导叶布置图,主轴零件图。

The Structural Design of Pump-turbine in
Fujian Xianyou Pumped Storage Power station
Abstract
Pumped storage power station plays a pivotal role in peka-clipping of power grid,being significant to improve the quality of power supply and the flexibility of -turbine,which is specially applied to pumped storage power station,transfers between turbine and pump according to the manage of power grid to fulfil the vital task of peak regulation and frequency adjustment. It also shows unique features in structure due to the characteristics of high water head, high speed, large capacity, complex operation condition and frequent start-stop.
Fujian Xianyou pumped storage power station is extremely typical when es to the scale,unit capacity,or the high-head pump- graduation project takes Guangzhou pumped storage power station as the object,aiming pleting the structural design of Francis pump-turbine in this power station by refering to related data,the design hand book of hydraulic turbine puter Aided Design overall assembly, the distributor assembly, as well as some of the major parts are well designed.
KEY WORDS: Fujian Xianyou pumped storage power station, pump-turbine, structural design, CAD
