Installation method of steam driven axial-flow blast furnace blower
The invention discloses an installation method of a steam driven axial-flow blast furnace blower. According to the method, center lines are placed in the transverse and longitudinal direction of a foundation, and reserved holes of foundation elevation bolts are retested; a hanging steel wire line is used as an alignment center line, a base is installed, and the elevation and levelness are adjustedby ball head bolts; a lower casing is installed, the levelness of the association plane of the lower casing is ensured, and the lower casing is placed on the base to eliminate deflection of the association plane of the lower casing; a lower stationary blade casing is installed, and is hoisted into the lower casing, and connecting bolts are fastened between the lower stationary blade casing and the lower casing; the association plane of the lower stationary blade casing is aligned, and an angle of a stationary blade at each level is measured; the angles of the stationary blades are opened to the maximum for rotor installation, and clearances and sealing clearances between rotor moving blades and tops of the stationary blades are measured; an upper stationary blade casing is buckled on theassociation plane of the lower stationary blade casing and tightens the connecting bolts; and an upper casing is buckled on the association plane of the lower casing, and the bolts are tightened afterinserting locating pins. According to the installation method of the steam driven axial-flow blast furnace blower, standard requirements are ensured to be met, and the safe and stable operation performance of a blast furnace is improved.
本发明公开了一种汽动轴流式高炉鼓风机的安装方法，本方法在基础横向和纵向放置中心线，复测基础标高螺栓预留孔；悬挂钢丝线作为找正中心线，底座安装并采用球头螺栓调整标高及水平度；下机壳安装并确保下机壳中分面水平度，下机壳放置在底座上，消除下机壳中分面挠度；下静叶承缸安装，下静叶承缸吊入下机壳中，紧固下静叶承缸与下机壳的联接螺栓；对下静叶承缸中分面进行找正并测量各级静叶的角度；将静叶角度开至最大进行转子安装，检测转子动叶与静叶顶之间的间隙以及密封间隙；上静叶承缸扣合于下静叶承缸中分面并紧固连接螺栓；上机壳扣合于下机壳中分面，插入定位销后紧固螺栓。本方法确保满足标准要求，提高高炉的安全、稳定运行性能。
