影响气举装置临界提升气体表观速度因素的研究

摘要

For further understanding the factors contributing to the apparent air velocity of critical lift in the process of air⁃lift, the theoretical analysis and experiments conducted showed that apparent air velocity in the critical lift decreases with an increase in the submergence ratio. Besides, both the installation number and angle of air nozzle have an influence on the apparent air velocity in critical lift. It is concluded that there exists an optimum number of nozzle for the critical lift under the same conditions.%为了进一步弄清在气举提升过程中影响临界提升气体表观速度的因素，进行了理论与实验分析，结果表明：随着浸入率增加，临界提升气体表观速度减小；气体喷嘴的安装个数影响临界提升气体表观速度，其它条件不变的情况下存在最佳喷嘴安装个数；喷嘴的安装角度也是影响临界提升气体表观速度的重要因素。
