The invention relates to the technical field of fluid machinery, in particular to a stacked double-cavity parallel piezoelectric pump with a partition plate at an outlet. The stacked double-cavity parallel piezoelectric pump with the partition plate at the outlet comprises two piezoelectric pump cavity components symmetrically arranged on two sides of a circulation plate, each piezoelectric pump cavity component comprises a pressing cover and an intermediate body, piezoelectric vibrators are installed on the pressing covers, piezoelectric pump cavities are arranged on the intermediate bodies,inlet grooves and outlet grooves are formed in the intermediate bodies, passive stop valves are installed on the inlet grooves and the outlet grooves, inlet holes and outlet hole are formed in the twosides of the circulation plate, the inlet holes communicate with the inlet grooves in the intermediate bodies on the two sides, partition plates are arranged in the outlet holes and divide the outletholes into an upper part and a lower part, the upper parts of the outlet holes communicate with the outlet grooves of the intermediate body at the upper side, the lower parts of the outlet holes communicate with the outlet grooves of the intermediate body at the lower side, inlet pipes and outlet pipes are installed on the partition plates, the inlet pipes communicate with the inlet holes, the outlet pipes communicates with the outlet holes. According to the stacked double-cavity parallel piezoelectric pump, the problem that in the prior art, fluid of a stacked double-cavity piezoelectric pump collides when flowing out, and consequently energy loss is caused can be solved.
Description
technical field [0001] The invention relates to the technical field of fluid machinery, and specifically relates to a stacked double-cavity parallel piezoelectric pump with a partition at the outlet. Background technique [0002] Piezoelectric pumps use piezoelectric vibrators fixed around them to be driven by alternating voltage, so that the volume of the pump chamber changes continuously and a certain pressure difference is generated inside and outside the chamber to drive the fluid to flow. Therefore, the volume change of the pump cavity when the piezoelectric pump is working determines the output capacity of the piezoelectric pump. [0003] The existing double-cavity parallel piezoelectric pumps generally have two structures, one is the "inline" structure, and the other is the "stacked" structure. The "inline" structure is relatively large, while the "stacked" structure When the medium fluid flows out, it will collide positively in the outlet hole and cause energy loss,...
