【Abstract】 The gas diaphragm pump with the magnetic spring structure is proposed,and the specific structure and operating principle of the gas diaphragm pump are presented.The core component of the gas diaphragm pump,including piezoelectric vibrator,passive cut-off valve,etc.have been chosen and designed.The structure of magnetic spring is analyzed.The relationship between the axial force and axial clearance of the magnetic spring has been determined through the theoretical calculation.The output flow and pressure of the gas diaphragm pump with different valve mouth diameters have been verified.The result shows that the gas diaphragm pump with the magnetic spring structure can greatly improve the volume change rate of the pump body,and the magnetic spring has excellent rigidity.Compared with the similar gas pump,the output flow and pressure have been significantly improved.更多还原
