| 目前关于气泡泵的实验研究主要使用电加热作为驱动热源，实验过程中系统运行周期长、操作复杂、误差明显、不利于获得准确的实验数据，针对以上问题，为了能够更加准确的掌握气泡泵的运行性能，采用气体输入法对气泡运动规律进行冷态模拟,开展气泡泵性能的实验研究，根据实验结果，对气泡泵性能影响因素进行分析，发现在保持其他影响因素不变情况下，气体输入量、沉浸比、加热功率与液体提升量均成正比，并论证了热态实验与冷态实验的结论具有一致性。同时，通过无因次法对气泡泵系统性能参数进行分析，得出了液体提升量与加热功率的相关函数关系式。关系式表明：在固定的沉浸比下，液体提升量与加热功率成正比关系。 |

| Abstract: |
| Electrical heating is mainly used as heat source in experimental research on bubble pump. Operational term is long, operation is complicated, deviation is distinct and accurate experimental data is not obtained. In view of the above question, In order to grasp the bubble pump performance more accurately, this system the bubbles’ movements with a device injecting air is simulated to realize the bubble pump’s normal operation under a cold condition and is used to study bubble pump’s performance. According to the experiment results, the bubble pump’s performance influencing factor is analyzed.And that is found that keeping other influencing factors constant, the gas input and immersion ratio and heating power is proportional to the amount of liquid lifted. And it is demonstrated that the hot experiment and cold experimental results are consistent. The bubble pump system’s performance parameters with actor analysis method is analyzed and is the relevant function equation between the heating power and the amount of liquid lifted attained. The function equation indicates that with a fixed immersion ratio the amount of liquid lifted is proportional to heating power. |
