Firstly, a patented new claw rotor is presented. The rotor profile is defined by parameters such as rotor radius, pitch radius, claw depth, contact angle and number of claws. Then, a new type of liquid pump using this new claw rotor is designed. Main components of the claw pump include a pair of claw rotors with five claws for transferring the liquid, a pair of gears for maintaining the two rotors with the same rotational speeds but with different directions, and a supporting housing for both the rotors and gears. Performances of the claw pump, such as specific flow rate, leakage and power consumption, can be predicted from design parameters of the rotor profile. Performances of the claw pump are also compared with those of lobe pumps and gear pumps to show the design advantages of claw pumps over the other two pumps. Finally, a prototype of the claw pump is manufactured, and performances, including flow rate, pressure head, rotational speed and power consumption, are measured. Performances of two similar traditional centrifugal liquid pumps and a gear pump are also measured for comparison with those of the claw pump. From the measured results, it shows that the proposed new claw pump has better performances than those of the traditional centrifugal pumps and gear pumps.口試委員會審定書 Ⅱ謝 Ⅳ文摘要 VI文摘要 VIII錄 X目錄 XII目錄 XVIII號說明 XX一章 緒論 1.1 簡介 1.2 液態幫浦的介紹 3.3 爪式轉子及液態幫浦之專利 10二章 文獻回顧與理論背景 15.1 轉子輪廓之理論與應用 15.2 具體流量以及面積效率 20.3 洩漏理論研究 22.4 幫浦總效率之理論研究 23.5 幫浦性能以及實驗架構 25三章 新爪式轉子液態幫浦之設計 27.1 爪式轉子之設計 27.2 間隙之設計與應用 29.3 新爪式轉子液態幫浦之細部設計 31四章 爪式轉子液態幫浦之性能分析 35.1 爪式轉子之具體流量 35.2 爪式轉子幫浦洩漏分析 45.3 爪式轉子液態幫浦之能量損耗 55五章 實驗與結果 57.1 實驗方法與理論 57.2 實驗設備 58.3 實驗步驟 64.4 實驗結果 64.5 實驗討論 79.5.1 洩漏結果之比較 79.5.2 幫浦效率之比較 85六章 結論與未來展望 97.1 結論 976.2 未來展望 98考文獻 101錄A 黏性係數對液態幫浦之影響 107錄B 齒底高與壓力角與具體流量之比較圖 109錄C 高效率馬達之詳細規格 111錄D 液態幫浦實驗之數據 113錄E 液態幫浦之軸承選擇與軸變形計算 121錄F 爪式轉子液態幫浦之其他變形 125錄G 液態幫浦應用於水上摩托車 129錄H 爪式轉子液態幫浦之濾網設計 131錄I 耐久測試幫浦耐久測試 1355757369 bytesapplication/pdfen-US液態幫浦揚程流量能量損耗爪式轉子幫浦效率具體流量liquid pumppressure headflow ratepower consumptionclaw rotorspump efficiencyspecific flow ratethesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/187218/1/ntu-98-R96522617-1.pdf
