An Ultrasonic Suction Pump with No Physically Moving Parts
نویسندگان
چکیده
A new ultrasonic suction pump is described in this paper. The pump uses suction force of the rigid cylinder tube vibrating at an ultrasonic frequency and has no physically moving parts. The pump is consists of a longitudinal bolt-clamped Langevin transducer (BLT) combined with a stepped horn working at its resonance frequency of 24 kHz. A glass tube of the half-wavelength-resonance length is glued at the tip of the horn. To enhance the pump performance, we introduce a reflection plate and a thin rod installed to the end of the glass tube with a small gap. The maximum pressure of 7.2 kPa and 23.5 kPa were recorded by using the reflection plate and the thin rod, respectively. In this study, we investigate the characteristics of the pump, and the operation physics experimentally. The highest pressure is the functions of the vibration velocity of the end surface of the glass tube and of the gap.

Design and fabrication of an ultrasonic thermoacoustic generator using metal nanocoatings (Research Article)
In this paper, we design, simulate, and build an ultrasonic heat generator. In thermoacoustics, heat generated by the passage of alternating current through a thin conductor produces a sound wave. In this method, unlike other methods of sound production, moving parts are not used to vibrate air molecules, and as a result, the frequency response of these generators is flatter than other sound ge...
متن کاملTemperature profile of a power-law fluid over a moving wall with arbitrary injection/suction and internal heat generation/absorption
The heat transfer for a non-Newtonian power-law fluid over a moving surface is investigated by applying a uniform suction/injection velocity profile. The flow is influenced by internal heat generation/absorption. The energy equation is solved at constant surface temperature condition. The Merk-Chao series is applied to obtain a set of ODEs instead of a complicated PDE. The converted ordinary diffe...
متن کاملAutomatic Control of the Coronary Suction Pump
___________ _ (J. Extra-Corpor. Tech. 18[4) p.219-220 Winter 1986) A coronary suction device is described which affords the surgeon direct control of blood aspiration. The device described is nondisposable and can be made up from extra level sensors. With use of the device, there was a reduction in the time that coronary sucker pumps were used, hence reducing the aspiration of air. As the coron...
