中文摘要:为了优化旋流泵的水力性能,找出影响旋流泵性能的主要结构参数,采用正交试验方法,选取叶轮外径D2、叶片数Z、叶片宽度b2、叶片出口安放角β2、叶片进口安放角β1为主要因素,选取L16(45)正交表得到16组方案,由数值计算结果级差分析初步获得各因素的较优取值范围,再次进行少因素的正交试验,通过级差综合分析法,探索主要因素对旋流泵的影响规律,找到了影响旋流泵性能的主要因素和次要因素,最终得出较优方案组合。原型机和较优设计方案内流场和试验结果对比分析表明:旋流泵进口处产生两个不同程度的回流损失;优化方案内流场回流损失较少,优于原型泵;较优方案比原型机的效率高出4.2个百分点,扬程高出10m左右;效率和扬程有一定的提高,满足设计要求,验证了正交试验的可行性。

Abstract:In order to acquire the main structure parameters impacting on performance of vortex pump and optimize the performance of the vortex pump, the orthogonal testing method was introduced. Impeller outer diameter D2, blade number Z, width of blade b2, impeller outlet blade angle β2 and impeller inlet blade angle β1 were chosen to be the main factors. So 16 sets of programs with 16 type of impellers were designed according to L16(45)orthogonal table. Optimum value range of each factor was preliminarily obtained through range analysis. Quadratic orthogonal test was conducted to investigate the effects of main factors and acquire the primary and secondary factors of the design parameters on the vortex pump, and an optimization scheme for further design was obtained. The internal flow field and experimental results of optimization scheme were compared with the original model, and it showed that pump inlet produced two back-flows with different degree; the back-flow loss of optimal model was less than that of the original model; the efficiency and the head of optimal model are both higher than those of the original model 4.2 percentage points and 10m, respectively. The improved efficiency and head can meet the design requirements. The orthogonal testing method has some feasibility to the performance optimization of vortex pump.

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.
