| Abstract: | During transfer of liquefied oxygen from 600 m3 low-pressure liquefied oxygen tank to 20 m3 medium-pressure liquefied oxygen tank,an over-pressure trouble occurs in the pipeline post the liquefied oxygen pump due to ice blocking. The transfer flow process of liquefied oxygen and the trouble phenomena are briefed,the causes for icing of liquefied oxygen pipeline are analyzed,and finally the solutions and the measures to improve the pipeline of liquefied oxygen transfer system are described. |
