旋轉導葉
英文
rotating guide vane-
The dynamo runs at rull speed to drive main shaft, then the main shaft makes the emulsifying wings in emulsification grove rotate, which absorbs the liquid in its brand groove into ring groove through guide vanes on upper and lower sides of the groove. the vanes spins circularly at high speed with the main shatf as center, and the blade and emulsificaton groove cut and crush it continuously. after that. it gers squeezed by the vanes highspeed centrifugal rotation. at last, it finishes isotropt emulsification tratment within extremely short time after continuous circulating mixing
由電動機全速運轉帶動主軸,經主軸轉動乳化框槽內之乳化翼片,使其將桶槽內之液體經框槽上、下兩側之導流葉片吸入環狀框槽內,經以主軸為中心高速圓周旋轉葉片;連續使乳化翼端刀面與乳化框間極小之間系高頻率之強力切割剪斷、粉碎,再借葉片高速離心旋轉排擠,持續循環混合,以極短之時間即可完成均質乳化之處理。The vortex simulated in this article include the shedding vortex induced by the vane trailing edge boundary layer, the endwall vortex generated by the endwall boundary layer interaction, the passage vortex generated by the rotor rotation, and the leakage vortex generated by the tip clearance flow
渦輪級內的渦運動包括:導向器葉片尾緣附而層引起的脫落渦;轉子通道內轉子的旋轉運動產生的通道渦;根腳區兩個端壁附面層干涉,形成的根腳渦;存在葉尖漏流時,出現的漏流渦。The main research outcomes were as follows : ( 1 ) the paper applied quasi - three dimensional design model and optimization design model based on si flow surface that was effected by runner ( impeller ) and guide vane jointly. the vortex flow, blade thickness limitation and runner ( impeller ) blade force functions were taken into account. the paper got the improved runners of hl240 type, which were runner hlx240d and runner hlx240e

本文對轉槳機組在過渡過程中的槳葉劃水產生水推力的數學模型進行了改進,在原來使用無邊界螺旋槳進行等效的基礎上,使用了導管螺旋槳對轉槳機組中的槳葉劃水進行等效,並且比較詳細的分析了影響轉槳機組軸向水推力的各個因素,以及給出了動態計算軸向水推力的公式,通過計算表明,使用改進后的動態水推力計算模型得到的結果能較好的反應實測的動態軸向水推力。The primary purpose of this paper is how to solve the overloaded propeller ' s condition. the style of propeller trailing edge cutting and shave on the pressure surface is adopted. the propeller ' s actual effect pitch will be reduced which cause the propeller ' s torque down
本文主要是考慮螺旋槳出現負荷過重時如何處理的問題,所以採用槳葉隨邊切割並在葉面處將翼型修順的方式,實質上是切割后導致螺旋槳實效螺距的減小,從而使螺旋槳吸收的轉矩降低來達到主機負荷降低的目的。The former one is a product of the pressure pulsation resulting from the fan blade periodically cutting the air, with the blade passing frequency as its base frequency and accompanied by higher harmonics. the wide - band turbulent noise is formed when the rotating fan forces the surrounding air to produce turbulent throw - outs and results in gas thickening and thinning processes
旋轉噪聲是由於風扇的葉片周期性地切割空氣,引起空氣的壓力脈動產生的,以葉片通過頻率為基頻,並伴有高次諧波。湍流噪聲是由於風扇運動導致的周圍空氣發生湍流脫體,使空氣發生擾動,形成氣體的壓縮與稀疏過程而形成的,是一個寬頻帶噪聲。This text, after analysing the interdependent relation between the flow law of the efflux, broken rock mechanism and the parameter of nozzle, the lead impeller nozzle and the auto - rotate nozzle were manufactured
本文在分析了射流的流動規律、破巖機理和噴頭參數三者之間相互制約、相互依存的關系后,設計並加工製造了內導葉輪噴頭和自旋轉噴頭。Studies have shown, lead impeller nozzle it forms the hole to be equal to size of the nozzle, gush out from light, difficult to arrange bits and realize it cut one layer of advantages effectively ; under the equal condition, rotate the nozzle by oneself, can be designed in accordance with the actual need while vary the size of aperture of hole, gush out the distance longer effectively, it is apt to give play to the role of its pulse broken rock
以此設計出限速部分的參數,且初步討論射流功率與轉速之間的關系。研究表明,內導葉輪噴頭形成鉆孔孔徑與噴頭大小相當,有效噴距小,不易排屑和實現其切向剝層優勢;同等條件下,自旋轉噴頭,成孔孔徑大小可依實際需要設計,有效噴距較長,易於發揮其脈沖破巖作用。Damping was then determined via exciting the equation at the critical frequency to get the transit decay which was then analyzed with the moving - block method. in chapter 4, the nonlinear dynamic equation of rotor - body system with inter - blade dampers ( taking all possible attachment offsets into consideration, spanwise offset, vertical offset and in - plane offset ) was modeled
本文重點推導了帶葉間減擺器(減擺器帶三個外伸量:展向,垂向和旋轉方向)的旋翼/機體耦合系統的非線性動力學方程,針對該方程提出了一種改進的多槳葉坐標變換方法。分享友人
