Abstract

Currently, pumps are used in various fields to supply air and liquid. These pumps include problems on wear, lifetime, working temperature and so on. To solve these problems, we have proposed an ultrasonic pump. Previously, we found an occurrence of pump effect when an opposing block faces an ultrasonically vibrating surface with a small gap. To observe the pump effect, an experimental setup with an ultrasonic transducer and a block was prepared. Fluid flow could be decided according to configuration of the opposing surface. When circumference of the opposing surface was tapered, air was discharged from the gap of two surfaces. On the other hand, when center of the surface was tapered, fluid was sucked into the gap. As experimental results, the maximum gauge pressure of 10 kPa with zero flow rate and the maximum flow rate of 60 ml/min with no load were observed.
