一、前言我厂装有两台天津发电设备厂制造的水轮发电机组,分别于73年底、74年底投产。水轮机主要参数: 型号:HL710—LJ—410 额定出力:82000KW 设计水头:60米最高水头:74米最低水头:55米设计流量:155水~3/秒吸出高度:-2米,(实际运行RS<-1.5米) 安装高程:89.3米。发电机型号:TS854/190—44。出力:80000瓩。 1.水机状况: HL710轮是HL702转轮的改型,由水科院等单位进行模型能量试验,部分点的汽蚀试验。为了加大过流量,提高出力。在叶片尾部等宽切割50mm,叶片北面离出水边二分之一
I. Preface Our factory is equipped with two hydro-generator units manufactured by Tianjin Power Generation Equipment Factory and put into operation at the end of 73 and the end of 74 respectively. Turbine Main parameters: Model: HL710-LJ-410 Rated output: 82000KW Design head: 60 meters Maximum head: 74 meters Minimum head: 55 meters Design flow: 155 water ~ 3 / s Aspiration height: <-1.5 m) Installation elevation: 89.3 meters. Generator Model: TS854 / 190-44. Output: 80000 瓩. 1. Water condition: HL710 round is a modification of HL702 runner, which is carried out by the ASTRI and other units of energy model test, part of the point of cavitation test. In order to increase over-flow, increase output. The width of the blade at the end of the cut 50mm, leaves the north out of the water one-half
