Researches on the Design and Operation of a Magnetic Drive Micropump for the Mixing of Compatible Fluids

Abstract:

This paper presents the current state of the conception of a magnetic drive micropump, different necessary constructive-technological and functional considerations, 3D modeling using parametric design, main geometric elements of the gears with helical teeth, specific calculations needed to determine the forces loads on the gears and a printed prototype of its model. Researches conducted from an actual micropump version in use led us to the design of an innovative variant, represented by a constructive solution with a driving gear and two driven gears. This ensures the possibility of displacing a fluid mixed of two compatible fluids, but also balancing the loads that appear in the gear mesh during the micropump's operation. This constructive solution is conceived for the size reduction of the pumping installation, for a good homogenization of the two mixed fluids, for an increased reliability of the micropump by reducing wear of moving components in contact, for a reduced noise and vibration.
