文摘利用三维造型软件创建了50ZB-25D型射流式自吸喷灌泵的内部全流场,运用FLUENT软件计算了该泵在3种情况,即回流阀完全关阀、不使用回流阀、回流阀完全关阀但不考虑分离室和储液室的影响等情况下的效率,探讨了回流阀、分离室和储液室对泵效率的影响.为了验证运用FLUENT计算射流式自吸喷灌泵效率的准确性,对该泵做了效率试验.运用FLUENT软件提供的M ixture两相流模型,对泵自吸过程中的气液两相流进行了非定常计算,探讨了自吸过程中泵体内气液两相流流动规律.结果表明,回流阀对泵效率的影响很大,而分离室和储液室结构的复杂性并不会产生大的影响;数值模拟结果与试验结果的吻合度较高,效率在各个流量点下相差不超过3%,扬程相差不超过1.5 m.
