Embodiment Construction
[0014] See attached figure 1 , an embodiment of a magnetostrictive double-cavity membrane micropump of the present invention can realize the mixed delivery of two liquids in equal quantities. The overall size of the micropump is Φ50×55 mm. The micropump includes a pump body, The displacement amplifying mechanism 12 and the magnetostrictive driver have three parts.
[0015] The pump body part includes connecting body 11, elastic diaphragm 13, gasket 14, screw 15, left inlet valve 16a, left outlet valve 17a, right inlet valve 16b, right outlet valve 17b, pump casing 18, spring 19. Such as figure 1 As shown, the pump housing 18 contains two equal-volume cavities, and two springs 19 are placed at the protrusions of the central part of the two cavities; the inlet valve 16 and the outlet valve 17 are connected with the left and right cavities of the pump housing 18 respectively. The body is connected, and sealant is applied at the connection position to ensure its tightness; the e...
