低漩涡大流量流线型流管无阀压电泵的设计与实验
Design and Experiment of Streamlined Piezoelectric Pump with Low Vortex and Large Flow Rate
摘要
Abstract
Valveless piezoelectric pump is widely used in the medical,however,there is a general and difficult problem to be solved:Low vortex and large flow rate are not compatible,resulting in the blood prone to thrombosis during blood delivery. In this paper, a new valveless piezoelectric (PZT) pump with streamlined flow tubes (streamlined pump)is proposed. The design method and the working principle of the pump are analyzed. The velocity streamlines are simulated,and the results demonstrate that there are no obvious vortexes in the flow tube of the streamlined pump. Five prototype pumps(two cone pumps and three streamlined pumps)are designed and fabricated to perform flow rate and flow resistance experiments. The experimental results illustrate that the maximum flow rate of the streamlined pump is 142 mL/min, which is 179% higher than that of the cone piezoelectric pump, demonstrating that the streamlined pump has a large flow rate performance. This research provides an inspiration for future research on simple structure,low vortex and large flow rate volume-type pumps,and also provides a useful solution for thrombosis preventing.关键词
