南桠河三级电站,系引水式地面厂房,共安装高水头混流式水轮发电机组3台。引水总管内径3.5米,分三根支管(内径1.6米)向各台机组引水,每台机组在蜗壳前装有一台φ1.6米双面止水球形伐。水轮机型号为H L004——LJ——210。设计水头265米;水轮机功率41700瓩;额定转速500转/分)发电机型号为TS425/125——12。额定出力4万千瓦;水轮机埋设部件的安装工作,是从1978年8月份开始的,电站于1983年三台机组相继投产发电。因为三台机组都系75年产品,设备缺陷较多。高水头高转速机组反应灵敏,要求安装质量高,在安装过程中,我们根据机组特点,对某些部件的安装施工方法
Nanxunhe III power station, Department of diversion ground plant, a total of high-head Francis turbine units installed three. The main water diversion pipe has an inner diameter of 3.5 meters and is divided into three branch pipes (1.6 meters in inner diameter) for diversion of water to each unit. Each unit is equipped with a φ1.6 meter double-sided water-stopping ball-shaped cutting in front of the volute. Turbine model H L004 - LJ - 210. Design head 265 meters; turbine power 41700 瓩; rated speed 500 r / min) generator model TS425 / 125--12. Rated output of 40,000 kilowatts; turbine installation of buried parts, from August 1978 onwards, the power station in 1983, three units have been put into operation. Because three units are 75 years of product lines, more equipment defects. High head and high speed unit responsive, requiring high-quality installation, the installation process, we based on unit characteristics, the installation of certain components of construction methods
