一简述乌溪江湖南镇水电站#4机组(水轮机型号HL200-LJ-250,250转/分,转轮叶片14个,设计水头90米,额定容量40800千瓦。发电机型号TS-520/182-24,额定容量50000千伏安)1979年9月试运行,当时水头约80米,空载时,水轮机摆度0.35mm,导叶开度100％,负荷3.3万千瓦时,水轮机摆度0.40mm(法兰0.24mm,上滑环0.55mm)。以后运行中曾达0.55～0.60mm。根据机组运行情况,进行动平衡试验,并相应采取了配重措施,空载摆度虽有所好转,为0.25～0.30mm,但随着机组负荷增加,水轮机摆度也逐渐增加。导叶开度50％时,摆度为0.45mm,导叶全开时,摆度为
A brief description of WuHeiJiangNanZhen hydropower station # 4 unit (turbine model HL200-LJ-250,250 r / min, runner blades 14, design head 90 meters, rated capacity of 40,800 kilowatts.) Generator Model TS-520 / 182- 24, the rated capacity of 50000 KVA) trial operation in September 1979, when the head about 80 meters, no-load, the turbine swing 0.35mm, guide vane opening 100%, load 33,000 kwh, turbine swing 0.40mm (Flange 0.24mm, slip ring 0.55mm). After running has reached 0.55 ~ 0.60mm. According to the operation of the unit, the dynamic balance test was carried out, and the counterweight measures were taken accordingly. Although the no-load swing was improved, it was 0.25-0.30mm. However, as the unit load increased, the turbine swing increased gradually. When the vane opening is 50%, the swing is 0.45mm. When the guide vane is fully open, the swing is
