摘要
对双入口压电泵进行了结构设计及工作过程分析,推导了单腔体压电泵的输出流量与入口截面积的关系。搭建了双入口压电泵的试验测试系统,分别对单入口压电泵和双入口压电泵的输出性能进行试验测试。试验结果表明:双入口压电泵的最大输出流量比单入口压电泵提高77.4mL/min;双入口压电泵的最大输出压力比单入口压电泵提高1.92kPa,双入口压电泵可以实现两种流体的混合。理论分析及试验结果表明:双入口压电泵可以提高单腔体压电泵的输出性能,并实现两种流体的混合,同时通过控制双入口压电泵的驱动频率,可以实现对两种流体的变量混合。
Structure design and working principle analysis of dual-entrance piezoelectric pump were carried out,and the relationship between output flow rate and the entrance area was inferred theoretically.The testing system was built and the output performances of single-entrance piezoelectric pump and dual-entrance piezoelectric pump were tested respectively.Testing results show that the maximum flow rate against zero back pressure of the dual-entrance piezoelectric pump is increased by 77.4 mL/min compared with single-entrance piezoelectric pump.The highest output pressure against zero flow rate of the dual-entrance piezoelectric pump is increased by 1.92 kPa compared with single-entrance piezoelectric pump.It is realizable for dual-entrance piezoelectric pump to achieve two kinds of micro fluid mixing.It turns out that the dual-entrance piezoelectric pump could enhance the output performance of single chamber piezoelectric pump,realize the mixing of two kinds of micro fluid,and variable mixing of two kinds of micro fluid by controlling the driving frequency of the pump.
