Abstract

本实用新型公开了入口带有特斯拉阀的方形大流量高压力压电气泵，属于微型压电泵技术领域，包括：隔板Ⅰ、泵体Ⅰ、泵体Ⅱ、隔板Ⅱ、导流板，均为方形板状结构由上至下依次固接；所述泵体Ⅱ与泵体Ⅰ结构相似，二者相对设置，且二者间设有压电振子，将泵体腔室一分为二；所述的泵体Ⅰ和泵体Ⅱ上均设有第一象限孔、第二象限孔、第三象限孔、第四象限孔、入气口、出气口、腔室、入气口特斯拉流道、出气口流道；所述出气口位于腔室中心，其上设有出气方向朝外的单向阀；所述的入气口特斯拉流道为对称并联的特斯拉阀结构，具有单向导通作用；泵体Ⅰ和泵体Ⅱ间可通过改变装配连接相对位置，实现两泵腔的串联增大压力、并联增大流量两种工作模式。

English (machine translation): This utility model discloses a square, high-flow, high-pressure piezoelectric pump with a Tesla valve at the inlet, belonging to the field of micro piezoelectric pump technology. It includes: a partition plate I, a pump body I, a pump body II, a partition plate II, and a guide plate, all of which are square plate structures fixedly connected from top to bottom. Pump body II has a similar structure to pump body I, and the two are arranged opposite each other, with a piezoelectric vibrator between them, dividing the pump body chamber into two.…
