中文摘要:基于泵的三元设计理论与数值试验相结合的方法,采用轴流式水泵的外形结构对某高比转数混流泵进行了设计,提出了高性能紧凑型水泵设计方法。首先,基于雷诺时均方法对该高比转数混流泵的性能进行了数值计算和分析,并将计算结果和试验值进行了比较,最大误差在3%以内,验证了数值计算模型的准确性。其次,采用轴流式水泵的外形结构基于泵的三元设计理论对该泵进行了重新设计,运用全三维考虑流体粘性的雷诺时均方法对设计结果进行计算分析与验证,最终的设计结果表明:新设计紧凑型水泵满足所有设计指标,在设计流量下裸泵效率达到了0.927,并且在较宽的流量范围内具有良好的水力性能。对比原混流泵和新设计紧凑型水泵性能,可以发现:新设计紧凑型水泵裸泵效率比原混流泵提高了3%,并且其轴面最大直径比原混流泵减少了38%,说明新设计的水泵能够有效减小泵的尺寸、重量并具有优异的水力性能。

Abstract:In order to study the design method of high performance compact pump, a high specific speed mixed-flow pump was designed with axial pump configuration by solving the 3-D inverse design equations and the full viscid flow iteratively. Firstly, the performance of the high specific speed mixed-flow pump was calculated using RANS simulation, the results of CFD simulation and test data were presented and discussed briefly. The errors of the mixed-flow pump power between the CFD simulation and pump test data were below 3% in the whole calculating region. Secondly, based on the axial pump configuration, the pump was redesigned by using 3-D inverse design method and CFD simulation iteratively. The final design result indicated that the pump had high efficiency of 0.927 on the design point and the flow within the pump was smooth without any separation and cavitation. In the end, the performance of the mixed-flow pump and the redesigned compact pump were compared, which indicated that the efficiency of the redesigned compact pump was higher than the mixed flow pump by 3%, and the transom size of the redesigned compact pump was smaller than the mixed-flow pump by 38%. The redesigned pump had compact size and excellent performance.

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.
