摘要
齐鲁石化热电厂 4号汽轮机由于前轴承箱及后汽缸基础沉降不一致 ,使前轴承箱扬度与转子 1号瓦处的扬度出现较大偏差 ,影响到机组的安全生产。通过采用支撑汽缸、抽出前箱、研磨台板基础的方法 ,完成了前箱及转子扬度的调整 ,使两者同心度趋于一致。机组大修后 。
Due to foundation subsidence of the front bearing box is not consistent with that of the rear cyninder of title steam turbine, great deviation occurred between uplift degree of frond bearing box and that of the rotor at bearing pad No.1, affecting safe operation of said unit. Through supporting the cylinder, drawing off the front bearing box, and grinding the tableplate of foundation etc., the adjustment of uplift degree for the front bearing box and the rotor has been completed, making the concentricity of them both to be consistent with each other. After major repair, the unit has successfully started up on its first run.
