刘家峡水电厂是一座以发电为主的电厂。装有5台水轮发电机组,总装机容量为122.5万千瓦。设计年平均发电量57亿度。1969年3月第一台机组发电,1974年底5台机组全部投产。经过十几年的运行实践证明,机组的过机含沙量不断增加,同时经过几个检修周期的运行,转轮的磨蚀破坏也在增大,给检修工作带来了困难。检修周期和工期以及检修质量越来越难以保证。同时,转轮经过多次大面积补焊处理后,运行特性有所改变,效率也不同程度地有所降低。
Liujiaxia Hydropower Plant is a power-based power plant. Equipped with five hydro-generator sets, with a total installed capacity of 1.225 million kilowatts. Design annual average generating capacity of 5700000000 degrees. In March 1969, the first generating unit was produced. At the end of 1974, all five units were put into production. After more than 10 years of running practice has proved that the unit of increasing sediment concentration, and after several maintenance cycle operation, runner abrasion damage is also increasing, to the maintenance work has brought difficulties. Maintenance cycle and schedule as well as the quality of maintenance more and more difficult to guarantee. At the same time, runner after many large-area welding repair, the operating characteristics have changed, the efficiency is also reduced to varying degrees.
