In this paper , spiral pipe flows generated by locally installing guide blade were researched 本文主要针对局部安装扭曲导流条的方式产生的圆管螺旋流做以研究。
Based on the previous research , the influences of boundary layer of guide blade were considered 本文在前人研究的基础上,主要考虑了导流条边界层对水流的影响。
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 增大后导叶出口安放角,可以消除环量和偏流,提高泵装置效率1 . 6 ~ 2 . 4个百分点。
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 本文针对电站风机性能监测系统研究较少的现状,在实验的基础上分析了现场加装进气箱和由于安装造成的导流器叶片开度不一致对风机性能曲线的影响,并在此基础上采用无节流方法测量流量,以风机调节性能曲线为依据,建立了基于径向基函数( rbf )神经网络的风机流量全程监测模型;以实验室4 - 73no . 8d离心风机为研究对象,探讨了rbf神经网络差压模型在变转速、变导流器开度和变管网阻力等工况下的应用精度和误差分布规律;最后用visualc + +语言开发了风机性能在线监测系统。
