Design and Test Rig Construction for Piezoelectric Pump having Sheet Type Check Valve

시트 체크밸브를 갖는 압전펌프 설계 및 펌프 실험장치 제작

In precision machinery industry, it's required with small size and low noise design to using in constant liquid delivery equipment. To accomplish it's purpose, we designed the check valve with rubber sheet of circle shapes as a possible assembly in pump body. The test equipment for piezoelectric pump was able to test pressure-flow property and output property of piezoelectric pump by variation(magnitude of voltage and frequency) of input power.
