In this paper , spiral pipe flows generated by locally installing guide blade were researched 本文主要針對局部安裝扭曲導流條的方式產生的圓管螺旋流做以研究。
Based on the previous research , the influences of boundary layer of guide blade were considered 本文在前人研究的基礎上,主要考慮了導流條邊界層對水流的影響。
Flow circulation and deviation could be eliminated by enlarging the back guide blade outlet incidence , and pump assembly efficiency could be increased by 1 . 6 ~ 2 . 4 percentage points 增大后導葉出口安放角,可以消除環量和偏流,提高泵裝置效率1 . 6 ~ 2 . 4個百分點。
Aiming at the study actuality of fan performance monitoring system and analysis of fan performance curve changes affected by inlet - box and the different fixed - angles of guide blades in the course of installation , a fan flow monitoring model based on rbfnn in whole flow zone was established in this thesis . in the model , the method of no throttle and fan performance curve were used as basis . and on the basis of that model , fan performance curves of 4 - 73no . 8d were approached with experimental data of different speed , different opening - angles of guide blade and different resistance of pipeline , the precision and the error law of model were studied 本文針對電站風機性能監測系統研究較少的現狀,在實驗的基礎上分析了現場加裝進氣箱和由于安裝造成的導流器葉片開度不一致對風機性能曲線的影響,并在此基礎上采用無節流方法測量流量,以風機調節性能曲線為依據,建立了基于徑向基函數( rbf )神經網絡的風機流量全程監測模型;以實驗室4 - 73no . 8d離心風機為研究對象,探討了rbf神經網絡差壓模型在變轉速、變導流器開度和變管網阻力等工況下的應用精度和誤差分布規律;最后用visualc + +語言開發了風機性能在線監測系統。
Presents the system established by taking variable - speed torque converter with adjustable guide blades as a pilot control unit and forming an open or closed loop feedback control system , and its outstanding advantages , such as high capacity , simplicity , reliability and good transmission efficiency owned by hydrodynamic drive , and the dynamic model developed for variable - speed torque converter with adjustable guide blades by means of theoretical analysis and regression analysis of experimental data , and concluds that the model is sophisticated and simple enough to be used as a tool for design , analysis and computer simulation of a hydrodynamic control system 以導葉可調式液力變矩器作為控制單元組成的開環或閉環液力控制系統,具有液力傳動裝置能容大、系統簡單可靠、傳動效率較高等顯著的優點.通過理論分析和試驗數據的回歸分析方法建立了導葉可調式液力變矩器的數學模型,模型既簡單,又有足夠的工程應用精度,為液力控制系統的設計、動態分析和性能預測提供了必要的理論基礎
