ADJUSTMENT OF FRONT BEARING BOX AND ROTOR'S UPLIFT DEGREE FOR STEAM TURBINE NO.4 AT THERMAL POWER PLANT UNDER QILU PETROCHEMICAL INC
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
一次启动成功
Abstract
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.
