Valveless pumping using a two-stage impedance pump

V. C.-C. LEE, Y. A. ABAKR, K.-C. WOO

Frontiers of Mechanical Engineering 2013, Volume 8, Issue 3,   Pages 311-318 doi: 10.1007/s11465-013-0270-x

Abstract:

Impedance pump is defined as a type of valveless pumping mechanism, where an elastic tube is joinedthe past, but little experimental work was found to exploit the principle of multi-stage impedance pumpingThe aim of this work is to have an insight on the deliverable head and pumping rate of an open-loop two-stageimpedance pumping system.

Research on the valveless piezoelectric pump with Y-shape pipes

ZHANG Jianhui, LU Jizhuang, XIA Qixiao

Frontiers of Mechanical Engineering 2007, Volume 2, Issue 2,   Pages 144-151 doi: 10.1007/s11465-007-0024-8

Abstract: A piezoelectric pump with its Y-shape elements is presented. Two Y-shape pipes are fixed outside the chamber serving as an inlet and outlet, with the chamber and a piezoelectric vibrator being the actor. The pump has the potential to be miniaturized and integrated. Eddies occurring in the Y-shape elements are smaller, which is beneficial for the transport of living cells or long-link macromolecules. In this paper, the structure of the pump is first presented. Then, the equations on the change in volume and the mean pressure in the chamber are established, as well as the relation between the flow rate and the working frequency of the piezoelectric vibrator. Moreover, the relation between the mean pressure in the chamber and the working frequency of the piezoelectric vibrator is established. Finally, experiments are carried out to test the characteristics of the pump and to verify the correction of the theory on this pump.

A control scheme with performance prediction for a PV fed water pumping system

Ramesh K GOVINDARAJAN,Pankaj Raghav PARTHASARATHY,Saravana Ilango GANESAN

Frontiers in Energy 2014, Volume 8, Issue 4,   Pages 480-489 doi: 10.1007/s11708-014-0334-6

Abstract: This paper focuses on modeling and performance predetermination of a photovoltaic (PV) system with a boost converter fed permanent magnet direct current (PMDC) motor-centrifugal pump load, taking the converter losses into account. Sizing is done based on the maximum power generated by the PV array at the average irradiation. Hence optimum sizing of the PV array for the given irradiation at the geographical location of interest is obtained using the predetermined values. The analysis presented here involves systems employing maximum power point tracking (MPPT) as they are more efficient than directly coupled systems. However, the voltage and power of the motor might rise above rated values for irradiations greater than the average when employing MPPT, hence a control scheme has been proposed to protect the PMDC motor from being damaged during these conditions. This control scheme appropriately chooses the optimum operating point of the system, ensuring long-term sustained operation. The numerical simulation of the system is performed in Matlab/Simulink and is validated with experimental results obtained from a 180 V, 0.5 hp PMDC motor coupled to a centrifugal pump. The operation of the system with the proposed control scheme is verified by varying the irradiation levels and the relevant results are presented.
