A pump that uses ultrasound and has no areas that can be rubbed.
Keywords: Ultrasonic Pump Non-contact
Pumps that transport liquids and gases use rubber valves to prevent backflow and employ bearings to support rotating parts. Since these components are constantly rubbing against each other, they can be a source of failure. Additionally, using rubber makes them unsuitable for low-temperature environments (where the rubber hardens) and high-temperature environments (where the rubber melts). By eliminating the rubbing parts, the probability of failure decreases, and they can be used in both low and high-temperature environments. By exciting high-frequency vibrations, which are inaudible to the human ear, on the surface of a solid and positioning another surface a few tens of microns apart, with some clever modifications to those surfaces, the fluid in the gap flows in one direction, functioning like a pump. There are no rubber components used, and there are no rubbing parts. Research is being conducted to increase pressure and flow rate with this type of pump configuration. The introduction of an ultrasonic non-contact rotating mechanism is also being considered.
