The sine and cosine linear valve piezoelectric pump has the advantages of high efficiency, large flow, simple structure, convenience in installation, low cost and the like.

Description

Technical field [0001] The invention relates to a sine-cosine linear valve piezoelectric pump, which belongs to the field of fluid machinery. Background technique [0002] A pump is a machine that transports fluid or transfers energy. In the traditional sense, pumps are generally driven by electric motors. No matter in theory, design method or manufacturing technology, it has reached a very complete level. However, limited by the working principle and structure, if an additional drive motor is required, the volume is large, and it is difficult to control the small flow due to electromagnetic interference. Therefore, it is difficult to meet the current aerospace vehicles, robots, automobiles, medical equipment, biological genetic engineering, micro machinery Application requirements. [0003] Piezoelectric pump is a new type of fluid driver. It does not require an additional drive motor, but uses the inverse piezoelectric effect of piezoelectric ceramics to deform the piezoelect...
