Abstract


The microfluidic system refers to the technique of control, operation and testing of the microscopic size of complex fluids , the micro - pump is one of the microfluidic system of the main driving device is an important sign of the level of development of the microfluidic system . Has developed various types of micro- pumps , which valve micro- pumps have become a research focus in recent years because of its simple structure . This paper presents a novel valveless micro pump - double cavity strikeouts sub valveless piezoelectric micro- pump . Its main components include the two piece cavity, on both sides of the cavity the expansion / contraction of the port, and three film (intermediate film is common to the film) and the film of the piezoelectric vibrator. The present novel micro-pump structure is simple , compact , easy to control, significantly improve the reliability and service life , may be able to achieve fine , a small ripple , high flow, high efficiency transfer fluid . Main topic of research contents: (1) A novel valveless micro pump of its working principle , and its actuation , the driver program , the composite piezoelectric transducer of the structure , the expansion / contraction of the shape and dimensions of the pipe , the pump the chamber and the buffer chamber shapes and geometric parameters of the research and design. (2 ) establish the key components of the new micro- pump - a composite piezoelectric oscillator mechanical model of a composite piezoelectric oscillator of elastic surfaces differential equations and the vibration equation is derived . Static analysis and dynamic analysis using ANSYS software oscillator , oscillator structure optimization . ( 3 ) study the microscale fluid flow characteristics , the expansion / contraction of pipe pressure loss coefficient and energy loss , the derivation of the expansion / contraction of the pipe flow and efficiency . FLUENT software expansion / contraction of the pipe , the pump chamber and the buffer chamber depth analysis of their structural parameters were optimized . The results for the piezoelectric driver valve micropump research and design to provide reference data for the research and application of micro- pump system has some theoretical value .
