20 螺旋離心泵的設(shè)計(jì),20,螺旋,離心泵,設(shè)計(jì) 湘潭大學(xué)興湘學(xué)院畢業(yè)設(shè)計(jì)- I -螺旋離心泵的設(shè)計(jì)摘要：此說明書設(shè)計(jì)了一臺(tái)用于輸送固液兩相流體的螺旋離心泵。本文的設(shè)計(jì)重點(diǎn)和難點(diǎn)是螺旋離心泵特有的是三維螺旋葉輪的設(shè)計(jì)。因此，葉輪設(shè)計(jì)是以何希杰和勞學(xué)蘇提出的螺旋離心泵葉輪葉片工作面和負(fù)壓面空間曲線方程為依據(jù)進(jìn)行的設(shè)計(jì)，葉輪葉片型線為對(duì)數(shù)螺旋線。根據(jù)設(shè)計(jì)參數(shù)和工作條件的要求，在設(shè)計(jì)上采用固液兩相流理論對(duì)葉輪、背葉片、壓出室等泵過流部件進(jìn)行水力設(shè)計(jì)。說明書從螺旋離心泵的結(jié)構(gòu)設(shè)計(jì)開始，分別進(jìn)行了葉輪的設(shè)計(jì)與繪形、壓水室及吸水室的設(shè)計(jì)、軸向力極其平衡、主要通用零部件的選擇、V 型帶傳動(dòng)設(shè)計(jì)和離心泵主要零部件的強(qiáng)度計(jì)算。本文為設(shè)計(jì)高效螺旋離心泵提供了一個(gè)重要的參考依據(jù)。關(guān)鍵詞：固液兩相流 螺旋離心泵 三維螺旋葉輪 空間曲線 對(duì)數(shù)螺旋線 湘潭大學(xué)興湘學(xué)院畢業(yè)設(shè)計(jì)- II -Spiral centrifugal pump designAbstract ：The article designs a screw centrifugal pump used to transport the mix flows of solid and liquid. The emphases and difficulty of the article is the design of three dimensional screw impeller owned by screw centrifugal pump. So, the design of impeller is designed with the space curve screw equation of impeller vane work surface of screw centrifugal pump and minus pressure surface raised by Xue su LAO and Xi jie HE. I take it as the gist of design. The impeller vane line is logarithm screw curve. Accord to the design parameter and the require of work condition, on the design , we do waterpower design to impeller , back vane, press out house and some flow over parts with the theory of the mix flows of solid and liquid. The article starts with structure design of screw centrifugal pump, and design the calculation and drawing of impeller, pressure out house and off water house, the force of direction of axis and its balance, the choice of the main parts in common use, the transmission design of V strip and intensity calculation of the parts of screw centrifugal pump. The article provides an important reference for designing the high efficiency screw centrifugal pump Key words：the mix flows of solid and liquid screw centrifugal pump three dimensional screw impeller the space the curve logarithm screw curve
