“…Experimental results show that when the voltage of the electrical signal is 150 V pp , at about 716 Hz, the flow rate reaches a peak of 700.15 mL/min. The proposed piezoelectric pump in this study does possess a larger flow rate compared with several recently reported works in terms of maximum flow rate [ 16 , 19 , 20 , 21 , 22 ].…”

“…For fuel supply in aerospace and new energy vehicles fields, and heat dissipation of highly integrated and large-load micro-electronic systems, etc., piezoelectric pumps should have the ability to continuously transport liquid with high flow rates, which are generally in the range of 10 mL/min to 1000 mL/min. And at present, for the study of high flow rate pumps, the flow rates are usually between tens to hundreds mL/min [ 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 ]. The output characteristics of piezoelectric pumps play a key role in the development of the above fields.…”

“…The pump achieved a no-load flow rate and a maximum output pressure of 600 mL/min and 6.8 kPa, respectively, at the applied voltage of 100 V and driving frequency of 250 Hz. Mohith et al presented a novel valveless micropump for biomedical applications operated using the amplified piezo vibrator [ 20 ]. The proposed micropump could obtain flow rates of 7.192 mL/min, 6.108 mL/min and 5.013 mL/min based on water, blood plasma and whole blood mimicking fluid, respectively.…”

To obtain a high flow rate, a resonant-type piezoelectric pump is designed, fabricated, and studied in this paper. The pump consists of four parts: a piezoelectric vibrator, a pump chamber, a check valve and a compressible space. The designed piezoelectric vibrator is composed of a rhombic micro displacement amplifier, counterweight blocks and two piezoelectric stacks with low-voltage drive and a large output displacement. ANSYS software (Workbench 19.0) simulation results show that at the natural frequency of 946 Hz, the designed piezoelectric vibrator will produce the maximum output displacement. The bilateral deformation is symmetrical, and the phase difference is zero. Frequency, voltage, and backpressure characteristics of the piezoelectric pump are investigated. The experimental results show that at a certain operating frequency, the flow rate and the backpressure of the piezoelectric pump both increase with the increase in voltage. When the applied voltage is 150 Vpp, the flow rate reaches a peak of 367.48 mL/min at 720 Hz for one diaphragm pump, and reaches a peak of 700.15 mL/min at 716 Hz for two diaphragm pumps.

Piezoelectric pumps play an important role in modern medical technology. To improve the flow rate of valveless piezoelectric pumps with flow tube structures and promote the miniaturization and integration of their designs, a cardioid flow tube valveless piezoelectric pump (CFTVPP) is proposed in this study. The symmetric dual-bend tube design of CFTVPP holds great potential in applications such as fluid mixing and heat dissipation systems. The structure and working principle of the CFTVPP are analyzed, and flow resistance and velocity equations are established. Furthermore, the flow characteristics of the cardioid flow tube (CFT) are investigated through computational fluid dynamics, and the output performance of valveless piezoelectric pumps with different bend radii is studied. Experimental results demonstrate that CFTVPP exhibits the pumping effect, with a maximum vibration amplitude of 182.5 μm (at 22 Hz, 100 V) and a maximum output flow rate of 5.69 mL/min (at 25 Hz, 100 V). The results indicate that a smaller bend radius of the converging bend leads to a higher output flow rate, while the performance of valveless piezoelectric pumps with different diverging bends shows insignificant differences. The CFTVPP offers advantages such as a high output flow rate, low cost, small size for easy integration, and ease of manufacturing.
