摘要
对不同上升管直径和不同浸没比的气泡泵进行了实验研究。根据气液两相流理论提出了气泡泵性能的计算公式,该计算结果与实验结果相一致。计算结果还表明,适当选择较小的上升管直径和较大的浸没比对提高气泡泵的效率是有益的。
An experimental study has been made for the air- lift pumps with differentriser tube diameters and submergence ratios. Based on the theory of air- liquidtwo phase flow, a formula for predicting air-lift pump performance is presen-ted. The calculating results show a reasonable agreement with those by expe-riments, and indicate that the efficiency of air-lift pump will be improved,provided that a small riser tube diameter and large submergence ratio canproperly be selected.
