本研究利用CO2雷射雕刻技術製程與表面熱接合技術製作直立式壓電幫浦，透過實驗流場以高速攝影技術擷取流場結構進行流場特性區分，配合流場數值模擬與體積流率量測資料，探討在不同鋼球位移量對幫浦效能之影響，以設計出符合經濟效益之有閥微幫浦。主要利用上鋼球及下鋼球設計使兩端閥門一開一關帶動流體運作。當使用鋼球ψ7mm、驅動電壓120V與方波頻率為31Hz之操作條件驅動下，有最大體積流量146.66ml/min，且能產生最大背壓70cm-H2O，腔體厚度最大可達70.6mm。當使用鋼球ψ9mm、驅動電壓120V與方波頻率為33Hz之操作條件驅動下，有最大體積流量121.6...顯示更多本研究利用CO2雷射雕刻技術製程與表面熱接合技術製作直立式壓電幫浦，透過實驗流場以高速攝影技術擷取流場結構進行流場特性區分，配合流場數值模擬與體積流率量測資料，探討在不同鋼球位移量對幫浦效能之影響，以設計出符合經濟效益之有閥微幫浦。主要利用上鋼球及下鋼球設計使兩端閥門一開一關帶動流體運作。當使用鋼球ψ7mm、驅動電壓120V與方波頻率為31Hz之操作條件驅動下，有最大體積流量146.66ml/min，且能產生最大背壓70cm-H2O，腔體厚度最大可達70.6mm。當使用鋼球ψ9mm、驅動電壓120V與方波頻率為33Hz之操作條件驅動下，有最大體積流量121.6ml/min，且能產生最大背壓25cm-H2O，腔體厚度最大可達106.6mm。藉由改變鋼球大小與腔體厚度進行系統性的分析，以期獲得較佳之操作條件。相信此研究可改善以往繁複製程的缺失，成本低廉，對學術及工業在微流體的操控及發展上有實質上的幫助。更新:翻出來有通順ㄇ???更新2:喔翻譯軟體我也會翻但是翻出來錯誤太多所以我想請英文高手幫我翻流暢一點的=.=更新3:flowthroughexperimentfieldisitisit我想請問一下@@isitisit怎ㄇ會那麼多呢??



This research makes use of CO2 Laser a carvings technique manufacturing process and surface heat to join together the technique manufacture erection type to press electricity pump, through the experiment flow a field to photograph a technique to pick to flow a structure to carry on flowing a characteristic distinction by high speed, the concert flows a number emulation and physical volume to flow rate measurement data, study at different steel ball the influence which move quantity to the pump effect match by designing an economic benefit it have the valve the tiny pump. Mainly make use of the last steel ball and descend a steel ball's design to make both ends valve a door an open a pass to arouse a fluid operation. Use a steel ball ψ 7 mms and drive the electric voltage 120 Vs and square wave frequency to drive for the operation condition with 31 Hzs bottom, there is the 146.66 mls/min of the biggest physical volume discharge, and can produce biggest carry on the back to press 70 cms-H2 Os, chamber body the thickness is the biggest and can reach to 70.6 mms.When use a steel ball ψ 9 mms and drive the electric voltage 120 Vs and square wave frequency to drive for the operation condition with 33 Hzs bottom, there is the 121.6 mls/min of the biggest physical volume discharge, and can produce biggest carry on the back to press 25 cms-H2 Os, chamber body the thickness is the biggest and can reach to 106.6 mms. By the change steel ball size and the chamber body thickness carry on system analysis, with the period acquire better operation condition. Believing this research can improve before the imperfection of the complicated manufacturing process, the cost is cheap, to academic and the industry have a substantial help on operation and development of tiny fluid. 2008-08-18 16:34:30 補充： 好像有點亂= = 不要介意 XD
