A novel piezoelectric pump is proposed in which the drive element consists of two large fiber composite (MFC) layers cross-bonded to a circular beryllium bronze substrate. Both finite element analysis and experiments were carried out. According to previous studies, MFC can be approximated by conventional piezoelectric ceramic materials, and the actuator works in a reciprocating motion. The vertical deformation of the actuator decreases as the thickness of the substrate increases, and increases as the angle of the MFC layer increases until the angle is 90°. The output performance of the new piezoelectric pump was tested with air and pure water. At a frequency of 15 Hz, the maximum output flow rate was 380.88 ml/min with air as the experimental medium. The pure output water was used as the experimental medium. The maximum output flow was 28.70 ml/min.

提出了一种新颖的压电泵，其中驱动元件由两个大纤维复合材料（MFC）层交叉粘合到圆形铍青铜基体上组成。进行了有限元分析和实验。根据以前的研究，MFC可以用传统的压电陶瓷材料近似，并且执行器以往复运动的方式工作。致动器的垂直变形随着基板的厚度增加而减小，并且随着MFC层的角度增加直到角度为90°而增加。新型压电泵的输出性能已通过空气和纯水进行了测试。在15 Hz的频率下，以空气为实验介质，最大输出流速为380.88 ml / min。纯净的出水用作实验介质。最大输出流量为28。
