Abstract

In present work, two piezo actuated cantilever beams are connected to a glass tube setup. The glass tube arrangement consists of the vertical tubes inserted in the liquid solutions, connector tubes, a glass bulb, and a helical tube, and it acts as a pump and mixer. When the piezo actuators are energized by AC voltage, vertical tubes start pumping the solution. At whatever point the two different solutions are in contact with each other in vibrating glass bulb and helical tube, mixing occurs. The proposed technique is a combination of active and passive mixers in which the liquid pumping action is utilized for fluid mixing. The diverse flowrates acquired at 65, 75, and 80 V_p-p are 0.038, 0.05012, and 0.06976 mL/s. UV-vis spectrophotometer tests mixed solutions for mixing performance. The important findings are, mixing performance depends upon two parameters, viz. solution concentration and flowrate.

压电驱动泵系统进行液体混合的实验评估

摘要

在当前的工作中，两个压电致动悬臂梁连接到玻璃管装置。玻璃管装置由插入液体溶液中的垂直管，连接器管，玻璃灯泡和螺旋管组成，并用作泵和混合器。当压电执行器由交流电压供电时，垂直管开始泵送溶液。在振动的玻璃灯泡和螺旋管中，两种不同的溶液在任何时候彼此接触，都会发生混合。所提出的技术是主动混合器和被动混合器的组合，其中利用液体泵送作用进行流体混合。在65、75和80 V _p-p时获得的各种流量分别为0.038、0.05012和0.06976 mL / s。紫外可见分光光度计测试混合溶液的混合性能。重要的发现是，混合性能取决于两个参数，即。溶液浓度和流速。
