摘要(Abstract):

采用三维造型软件创建了射流式自吸喷灌泵全流场,运用Fluent软件模拟了泵在回流阀关阀、回流阀开启2种情况下的内部流场,预测了泵的扬程、效率。并对泵在回流阀关阀、开启2种情况下分别进行试验,结合数值预测结果与试验结果分析回流阀对泵性能的影响。结果表明,回流阀对泵的扬程、效率影响较大。
The self-priming irrigation pump's model was created by using three dimension modeling software,and the pump's internal field with FLUENT software under two different conditions was simulated to predict the pump's performances.the pump's performances was tested by experiment.The results indicate that the valve has great influence on the self-priming irrigation pump's performances.
