| 摘 要： | 搭建了低温管路预冷过程实验台,并对不同管长和不同入口压力下低温管路预冷过程中压力和温度的变化情况进行了实验研究。结果表明,管路较长时,不稳定现象表现得更加剧烈,管路预冷时间变长,并会产生更大的压力峰值。

| Abstract: | The experimental device of pre—cooling of cryogenic pipe was establised.The pressure and temperature variations of cryogenic pipe during pre—cooling process was experimental investigated,The results show that the longer pipe will cause more seri- ous unsteady process and increase the cooling time.Meanwhile,the peak value of the pressure was increased. |

| Keywords: | Cryogenic pipe Pre—cooling Peak pressure |
