dc.description.abstract | 本研究是利用壓克力為基材來製作無閥式微幫浦,而此幫浦是利 用壓電片上下振動作為流體的驅動來源,並利用設計的漸張管/漸縮 管原理來得到所需的流量。在本研究中對於漸張管/漸縮管的長度以 及開口角度不同的單一振動腔之微幫浦來作一比較。發現在相同開口 角度下,長度的長短所得到最大流量值是相同的,但是長度較短的微 幫浦其趨勢較為平緩,亦即在最大流量值附近敏感度較低,因此性能 較好。而在開口角度方面,則是比較4.6°與9.8°,發現開口角度在 9.8°時性能較好,亦即所得到的最大流量值較高。此外在本研究中也 針對串聯式雙微幫浦作流量的分析,發現固定兩個振動腔中的一個, 只驅動另外一個振動腔,都可以達到流量提升的效果;而且也比較同 相位與不同相位差對於流量的影響,發現在相位差為90°時所得到的 最大流量值最大且為單一振動腔微幫浦的三倍。 | zh_TW |
dc.description.abstract | This study is to fabricate a valveless micropump by using PMMA materials, and the micropump uses piezoelectric disk to drive the fulid, and it uses diffuser/nozzle principle to get the flow rate. In diffuser/nozzle design, the micropump compares different length and angle with the other one. It may be seen that on the same angle the maximum flow rates of the different length single micropumps are the same, but the trend of the shorter length is smoother and sensitivity is lower near the maximum flow rate. On the different angles of 4.6°and 9.8°, it could be seen that the performance and the maximum flow rate of 9.8° is better. In addition, in the study it also analyse flow rate of the dual micropump in series. It could be seen that fixing one chamber and driving the other one is promoting the flow rate. it also fabricate dual chamber micropump in series to compare the flow rate with single chamber micropump in phase and in anti-phase, and it could be seen that at the phase angle of 90°, a three-fold increase of flow rate is relative to that of a sinle chamber operation. | en |
