摘　　要：工业蒸汽透平驱动离心压缩机的机组在石油、石化行业有广泛应用,其是否可以持久、稳定地运转直接决定该石油石化装置的效益产出情况,机组的轴系找正精度又是其能否长期稳定运行的关键因素,若安装过程中存在较大误差,会造成安装工作返工,机组振动异常,推力轴承温度过高,支撑轴承温度过高等问题,直接影响机组运行。该文主要剖析该装置的轴系布置原理及安装找正方法,轴向找正利用两表法消除蒸汽透平与离心压缩机转子的轴向窜动,利用两轴同盘的方法消除打表盘端面跳动误差,径向利用单表法和两轴同盘消除打表盘外圆的跳动误差,以提升轴系装配精度。Industrial steam turbine-driven centrifugal compressor units are widely used in the petroleum and petrochemical industries,and their ability to operate reliably and consistently directly determines the efficiency and output of these facilities.The precision of the shaft alignment in these units is a key factor in their long-term stable operation.If significant errors are present during the installation process,it can lead to rework,abnormal unit vibration,excessively high temperatures in thrust bearings,and excessive temperatures in support bearings,all of which can directly impact the operation of the unit.This paper primarily analyzes the principles of shaft layout and installation alignment methods for these units.Axial alignment uses the two-gage method to eliminate axial movement between the steam turbine and the centrifugal compressor rotor,and the method of aligning both shafts simultaneously is used to eliminate end-face runout errors when taking gage readings.Radially,the single-gage method and the method of simultaneous shaft alignment is used to eliminate runout errors of the outer circumference of the gage disk,thereby enhancing the precision of shaft assembly.
