Theoretical And Experimental Research On The High-Viscosity Piezoelectric Pump

Piezoelectric pump is a kind of new transmission fluid device driven by the piezoelectric transducer components. Piezoelectirc pump is also a new kind of superior smart materials actuator. It is a good try and a profound innovation that using piezoelectric ceramic materials as fluid pump actuator driving components. Along with the continuous deepening researches on the piezoelectric pump, the liquid media has not only involved in water. In some conditions, the piezoelectric pump was used to transmit the high viscosity liquid. As everyone knows, the different fluid has their different viscosity. How would piezoelectric pump work under different viscosity; what are the transmission characteristics of different viscosity liquids; how is the law and how to design the piezoelectric pump prototype using for pumping the high viscosity liquid. These are precisely the issues discussed in this paper. The full dissertation is divided into seven chapters, mainly as follows:1. PrefaceIn recent decades, the study on the piezoelectric pump has transfored from the structure and principle to the market-oriented direction. Nowadays, the research and development trends of piezoelectric pump are roughly two directions: the one is to high-pressure, large piezoelectric pump flow direction; the other is to the size miniaturization, less power consumption, high output accuracy direction. After more than 20 years development, piezoelectric pump has been coming out of the laboratory and gradually applied to practical workplace with the bright market demand prospects. Compared with the traditional pump, piezoelectric pump has many unparalleled advantages: precision micro flow control, no magnetic...
