摘要

研究了被动阀压电泵在方波驱动下出现的吸程出流现象

建立了被动阀压电泵的流体力学模型与振动模型

依此对吸程出流现象的物理过程进行了理论分析

推出了吸程时出口阀开启高度的计算公式。测量了吸程时压电泵在0.4

0.8

45 Hz等不同工作频率下出口阀的开启高度

并对公式中影响吸程出流的其余因素进行了实验验证。理论分析指出

流动惯性是产生吸程出流现象的根本原因

同时惯性流在排程中亦存在。实验结果表明

压电泵工作频率增加时出口阀的吸程开启高度会减小

出口阀刚度、入口与出口负载增大时吸程流会减小

实验结果与理论计算公式符合较好。分析认为

压电泵的输出流量应当包含容积流与惯性流两部分

在进行压电泵精密流量控制时应同时考虑这两部分的作用。

Abstract

The sucking outflow phenomena of a passive piezoelectric pump under the square wave driving is studied and a hydrodynamics model and a vibration model of the passive piezoelectric pump are built to analyze theoretically the physical process of the sucking outflow process.Then

an open height formula of the exiting valve in sucking processing is derived. The open height of the piezoelectric pump is measured during the sucking outflow process under different frequencies of 0.4

0.8

45 Hz

and the other factors effecting on the sucking outflow in the formula are verified. In the theoretical analysis

it points out that the flow inertia is the root cause for the outflow sucking phenomena

and the inertial flow also exists during the draining process. The experiment indicates that when the piezoelectric frequency increases

the open height of the exiting valve during sucking process decreases. When the exiting valve rigidity and the loadings in input and output increase

the outflow decreases.The results above are coincident with the formula well. It concludes that the output flow of the piezoelectric pump should include two parts: cubage flow and inertial flow

which should be considered in the same time when the flow of the piezoelectric pump is controlled precisely.
