中文摘要:根据轴流泵进口导叶片的设计要求,设计了可调进口导叶并开展了不同安放角进口导叶轴流泵装置的三维定常数值计算,获取了进口导叶对轴流泵装置水力性能调节的综合特性曲线,建立了带可调进口导叶轴流泵装置水力性能预测的多元非线性回归预测数学模型。依据数值计算结果和速度三角形分析了可调进口导叶对转轮及轴流泵装置水力性能的影响,结果表明:在进口导叶安放角0°时,相比不带可调进口导叶的轴流泵装置,在高效区及小流量工况时带进口导叶泵装置的能量性能变化很小,大流量工况时进口导叶的水力损失较大进而导致带进口导叶泵装置的效率下降幅度较大。随进口导叶安放角由0°逐渐向正角度增大时,泵装置的最优工况向小流量方向偏移,泵装置的流量效率曲线呈现出整体下降的趋势;随进口导叶安放角由0°逐渐向负角度减小时,泵装置的最高效率先增大后减小,但泵装置的最高效率点对应的流量未发生改变。

Abstract:The theoretical analysis and numerical simulation method were used to study the influence of inlet guide vane on the hydraulic performance of axial-flow pumping system. The inlet guide vane was designed based on design requirements. The three-dimensional internal flow of axial flow pumping system was simulated in different installation angles of inlet guide vane. Overall performance curves of axial-flow pumping system with adjusted inlet guide vane were obtained and the multiple non-liner regression prediction mathematical models of the hydraulic performance were established based on the results of numerical simulation and velocity triangle analysis. Compared with the pumping system without inlet guide vane, the hydraulic performance of pumping system with inlet guide vane changes little in the high efficiency area and small flow rate condition, but the efficiency of pumping system drops greatly because the hydraulic loss of inlet guide vane increases greatly in the large flow rate condition. With the increase of positive installation angle of inlet guide vane, the high efficiency operating condition is offset to small flow rate and the whole efficiency curves of pumping system would drop. While, with the decrease of negative installation angle, the high efficiency of pumping system increases firstly then decreases. The flow rate doesn’t change in the high efficiency operating condition of different negative installation angles.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
