Zhao Shaowu,Zhang Hao,Qin Tailing(Air Separation Workshop,Yankuang Guohong Chemical Engineering Co.,Ltd.,Zhongxindian Town,Zoucheng 273512,Shandong,P.R.China)  
At initial period from start and during operation of high-pressure liquefied oxygen pump necessary for 28000 m3/h inner compression process air separation plant,abnormalities such as damage of bearing and seal,which impairs the normal operation of air separation plant.Through technical reform and optimized operation,the operation period of high-pressure liquefied oxygen pump is prolonged.Here,the technical parameters of high-pressure liquefied oxygen pump are briefed,the technical reform and the measures to optimize the technical process are described,and experiences on operation and maintenance of high-pressure liquefied oxygen pump are summarized.
