Piezoelectric Hydraulic Pump Development
Journal of Intelligent Materials Systems and Structures, 2000A piezohydraulic pump is presented that makes use of the step-and-repeat capability of piezoelectric actuators. This work discusses piezohydraulic pumping theory, pump design, and pump performance. Efficiency is analyzed for the pump cycle with theoretical efficiency being 1.0. Loss mechanisms that result in actuator heating are discussed. The pump was

Development of Piezoelectric Diaphragm Pump
Solid State Phenomena, 2012In the present work, a piezoelectric diaphragm pump was designed and investigated. The pump uses a piezoelectric diaphragm transducer as the driving component, and two check valves located at the inlet and outlet to control the flow direction. The displacement of the transducer was first measured statically and dynamically.

Development of an inertial piezoelectric pump with separable chamber
Review of Scientific Instruments, 2022This paper presents an inertial pump with rectangular piezoelectric actuators. The mass block adhered at the free end of the actuator increases the actuator deformation, and the pump chamber is separable. Theoretical and experimental analyses are conducted.

A pump is comprised of a piezo-electric vibrator mounted in a casing. The piezo-electric vibrator is coated with an elastic elastomer layer, and a peripheral part of the elastomer layer is secured to the casing within the casing. Suction and discharge of fluid is performed by means of piezo-electric vibrator vibrated by applying alternative current ...

Modeling and testing of a novel piezoelectric pump
IEEE International Conference on Robotics and Automation, 2004. Proceedings. ICRA '04. 2004, 2004While there is a wide range of actuation technologies, none currently rivals the overall performance (power density, bandwidth, stress, stroke) of conventional hydraulic actuation [1]. It is well known in the actuation community that the power-to-weight ratios and the power-to-volume ratios of hydraulic actuators are, respectively, around 5 times and ...
