摘要 针对膜片式压电泵气体驱动能力不足,被输送气体流动受阻时压电振子易发热受损,以及叠堆式共振压电泵造价高昂等问题,提出了一种以圆环状压电双晶片为动力源,通过位移放大机构驱动的新型共振式气体压电泵.对新型共振式气体压电泵的工作原理及其位移放大原理进行了分析,建立了该泵的振动力学模型.分析结果表明,该泵位移放大效果与压电双晶片提供的驱动位移有关,系统放大倍数与弹簧片和压电振子的刚度、系统的黏性阻尼因子及激励频率有关.设计并制作了新型共振式气体压电泵的试验样机,使用阻抗分析及激光测量方法测试了其位移放大效果,并验证了气体输出性能.试验表明,在70 V的正弦交流电压驱动下,该泵通过共振方式可将输出端位移放大至压电振子位移的42倍以上,气体输出流量可达1 685 mL/min. 在气体流动受阻的情况下,该泵连续工作2 000 h无明显温升.

Abstract: The pumps driven directly by piezoelectric membrane not only have a poor performance when pumping gas, but also they may be damaged with a high temperature generated by the piezoelectric membrane when the flow of gas is blocked. Even though the pumps driven by piezoelectric stack have an excellent performance, they are quite costing. To solve the problems above, a novel piezoelectric pump was presented. The pump was driven by an annular bimorph and the displacement of the diaphragm was amplified at the resonance frequency. Firstly, the working principle of the pump was described, and a mechanic model of vibration was built to clarify displacement amplification principle. The analysis shows that the amplification factor is related to the stiffness of spring lamination and piezoelectric vibrator, viscous damping coefficient of system and driving frequency. The experimental prototypes were manufactured and the experiments indicate that the amplification factor of displacement amplifier is more than 4.2 at a 70 V sinusoidal AC driving voltage, the maximum flow rate could be up to 1 685 mL/min; when the gas flow is blocked, the pump can operate continuously as long as 2 000 h without a noted temperature rise in bimorph.
