锦江水电厂1号、2号机组转轮发现有多处裂纹，个别叶片随时可能断裂，严重威胁着电厂的安全生产。通过计算、调研，确定重新更换不锈钢转轮的改造方案，待新转轮投产出力达到预期要求后，再把机组出力提高至15.4MW的增容方案。机组改造后运行效果很好，达到预期目的。
錦江水電廠1號、2號機組轉輪髮現有多處裂紋，箇彆葉片隨時可能斷裂，嚴重威脅著電廠的安全生產。通過計算、調研，確定重新更換不鏽鋼轉輪的改造方案，待新轉輪投產齣力達到預期要求後，再把機組齣力提高至15.4MW的增容方案。機組改造後運行效果很好，達到預期目的。

Many cracks were found in the impellers of Unit 1 and 2 inJinjiang Hydropower Station, which exposed some of the blades to the risk of fracture and seriously threatened the safety operation of the station. Through calculation and investigation, a capacity-increasing transformation plan was determined, i.e., to replace the original impellers with proof stainless steel ones, and raise the unit output to 15.4 MW after the new impellers satisfy the requirements. Satisfactory results were obtained after the transformation.
