摘　　要：醋酸反应釜是醋酸系统的重点设备,反应釜由锆/钢复合材料焊接而成,主要由7个部件组成:电机、变速箱、机械密封、机轴、导流板、叶轮和轴套等。由于反应釜控制的温度和压力较高,所以对于特材设备的日常维护就显得尤为重要。根据不同部件的工作特点,重点阐述了反应釜顶部密封垫片的更换和变速箱的拆检以及回装时的注意事项等。An acetic acid reactor is important equipment in acetic acid system.It is welded with composite material of steel and zirconium.It is consisted of seven components,motor,gear box,mechanical sealing,shaft,guide plate,impellers and bushing,etc.The daily maintenance of special material equipment becomes more important because of the high temperature and high pressure controlled by the reactor.According to the characteristics of different components,this paper states the following points：exchange of sealing gaskets on top of a reactor and considerations of overhaul and restoration of the gear box.
