摘要

提出了一种新型的非对称坡面腔底无阀压电泵

这种泵巧妙地利用了泵腔内部的空间

将泵腔底部沿吸入口和排出口方向设计成非对称坡面形状

非对称坡面腔底与压电振子之间形成非对称交替排列的一组锥形流道。当泵工作时

使流体产生单向流动

从而可以不再需要传统的锥形流管;建立了这种泵关于平均值的流阻系数与泵流量关系的力学模型

并利用该模型分析了泵的工作原理;最后制作了非对称坡面腔底无阀压电泵

利用试验证明了上述理论的正确性。试验用泵采用的工作电压为220 V

工作频率为50 Hz

压电振子有效直径为30 mm

当非对称坡面的倾角差为70

工作介质为水时

泵产生了4.67 mm水柱的压差。

Abstract

A novel valve-less piezoelectric pump with Unsymmetrical Slopes Chamber Bottom (USCB) was presented. It ingeniously takes advantage of the space of the pump chamber by developing its bottom into an unsymmetrical slopes shape along the direction of the axis of the inlet and outlet

as a result

a series of diffuse channels and nozzle channels are alternatively formed between the USCB and the piezoelectric vibrator which is opposite to the USCB. It can force the fluid in the pump chamber to produce net flow when the pump works

and the regular diffuse/nozzle elements fitted outside the chamber can be eliminated. Mathematic model of this pump is established to present the relationship between the mean energy loss and the volume flow rate of the pump. Based on the mathematic model

the working theory of the pump is analyzed. Finally

a real USCB valve-less piezoelectric pump is manufactured

and the theory above-mentioned was verified by the pump in a test. Under conditions of the working voltage of 220 V

working frequency of 50 Hz and the diameter of the piezoelectric vibrator in 30 mm

the pressure difference produced between the inlet and outlet is 4.67 mm column when the pump works on water.
