摘要：The volume valve piezoelectric pump has received increasing attention from many areas because of its different characteristics such as the absence of chemical pollution and electromagnetic pollution.However,when the pump is working,it produces cavitations and the air bubbles that originate from these will flow out of the pump.Cavitations occurring in the pump will bring out noise and shorten the life of the pump.Furthermore,air bubbles flowing out of the pump will hinder its application in areas such as medical treatment and health care where blood transfusion and infusion are concerned.As a solution to this disadvantage,the CR3DMS (cavitations resistance with 3-dimensional mesh structure) method is developed,which is tested and verified to be effective on not only reducing the occurrence of cavitations and eliminating cavitations' flowing out,but also restraining the emission of noise.In conclusion,the pump with CR3DMS,on the relationship between flow and driving frequency and the relationship between flow and the number of Resistant-Layers in both theory and test,are analyzed.
