摘　　要：气泡泵是单压吸收式制冷循环的重要组成部分,基于Einstein制冷循环理论,搭建气泡泵实验台,在标准大气压下以水为工质,研究了在加热功率为300~1650 W,沉浸比为0.4,管径为8 mm、10 mm、12 mm,提升管长600 mm状况下单管对导流式气泡泵连续性性能的影响。实验结果表明:在加热功率为300 W和450 W时,随着管径的增加,液体累计提升量最大值反而减小,而随着加热功率的增加,从650 W开始,管径越大,液体累计提升量的最大值越大,在最大功率1650 W时,三种管径的提升管最大累计提升量分别为:6.667 kg、10.059 kg和13.337 kg。实验结果对气泡泵效率在提升管管径的选择上具有指导意义和参考价值。Bubble pump is an important part of the single-pressure absorption refrigeration cycle.Based on the theory of Einstein refrigeration cycle,a bubble pump performance test system was build.At an atmospheric,under the condition of heating power in 300~1650 W,immersion ratio is0.4,riser diameter is 8 mm,10 mm,12 mm and riser length at 600 mm,the device,which is used water as the working fluid,is studied to test the continuous performance of guided bubble pump.The experimental results shows that when the heating power is 300 W and 450 W,the maximum capacity of the liquid lift decrease as the diameter increase;while from 650 W,the larger the diameter,the greater the maximum capacity of lift liquid;and when the power is 1650 W,the maximum capacity is6.667 kg,10.059 kg and 13.337 kg,respectively.The experimental results are of guiding significance and reference value for the selection of bubble pump efficiency in riser pipe diameter.
