Abstract

本实用新型公开了一种压电泵和其配管,该压电泵包括进出口配管、上下壳、换能片、阀片和密封圈。其中一个核心的方法是将换能片的定位做成圆周边固定不能伸缩——换能片的外圆柱面与下壳的内圆柱面为紧配合定位。把壳体和换能片形成的工作腔内流体流动的表面做成弧面或曲面等流线体形状。在泵的进出口加一段配管,有利于流体的流动从紊流状态向稳流状态转变。这些方法能有效地降低无用功的消耗,极大地提升泵的效率。

Description

压电泵和其配管
技术领域
本实用新型涉及微型泵,特别是,涉及一种以压电陶瓷片为能量转换装置的压电泵及其配合使用的配管。 
背景技术
压电泵是一种新型泵,因为它的节能环保、体积小、重量轻、噪音低等许多优点,而被许多技术工作者看好它的应用前景,这种泵因为有许多技术基础工作的研究没有做透切,技术指标的提升有不少可以努力改进的空间。 
实用新型内容
本实用新型从换能片的安装定位、泵体工作腔的设计和管路配置方面来提升泵的性能指标。 
本实用新型的技术方案如下:一种压电泵和其配管,由进出口配管、上下壳、换能片、阀片和密封圈等零件组成。其中一个核心的方法是将换能片的定位做成圆周边固定不能伸缩,最好是机械方法的紧配合——换能片的外圆柱面与下壳的内圆柱面为紧配合定位,这种做法相当于杠杆原理的支点做在了圆周边,把换能片水平方向的伸缩变化最大化的转化为垂直振幅了,从而有效地提升了泵的工作腔的体积变化率,也就相应地提升泵的性能指标。我们把下壳和换能片形成的工作腔内流体流动的表面做成为无尖锐过渡的弧形面,或为逐渐变化的曲面和流线体形状,有利于减少流体流动的阻力和加速度突变,从而提高能量转化的效率,相应地也提高了泵的性能指标。我们在泵的进出口加一段配管,有利于流体的流动从紊流状态向稳流状态转变,从而降低了流体流动过程中的 能量消耗,达到了节能的目的。 
附图说明

图2是本实用新型中换能片的结构图 
图3是本实用新型中下壳的结构图 
图4是本实用新型中压电泵和其配管的仰视图 
图5是本实用新型中换能片的俯视图 
图6是本实用新型中下壳的结构图的俯视图 
具体实施方式
以下结合附图和具体实施例,对本实用新型进行更详细地说明。 
图1是本实用新型中压电泵和其配管的结构图,该泵由进口配管(1)、上壳(2)、换能片(3)、阀片(4)、下壳(5)、密封圈(6)和出口配管(7)等零件构成。上壳(2)和下壳(5)用螺钉连接或超声波焊接等方法将这些零件有机地组合在一起形成一个完整的压电泵。早前许多已报的专利或者是已经试产的压电泵产品是以图2中换能片(3)的(101)面和图3中下壳(5)的(102)面作为换能片(3)的定位面,而换能片(3)的外圆柱(A)面是可以自由伸缩的,本专利中将下壳(5)的内圆柱(B)面和换能片(3)的外圆柱(A)面以紧配合的方式限定,使换能片(3)通电后产生的伸缩变化最大化的转化为垂直振幅,从而提高了能量转化的效率。在图3中,我们把下壳(5)的(103)面做成流线体形式的弧面或曲面,减少流体流动过程中的阻力和涡流,也有利于 能量最大化地转化为有用功。在图1中,我们把压电泵的进出口再配一节管子,由于这种管子有利于把紊流变为稳流,从而减少了流体在进出口部位的能量损耗,相应地也就提高了压电泵的工作效率。
