The working principle of miniature diaphragm pump

The miniature electric diaphragm pump is powered by a miniature DC motor which drives an internal eccentric mechanism for eccentric motion, and the eccentric movement drives the internal diaphragm for reciprocating motion. So how does a miniature diaphragm pump work? Here's a brief introduction for you

Miniature diaphragm pumps use the rotation of a screw to draw in and discharge fluid. The screw of a miniature diaphragm pump is the active screw, and the main screw rotates on both sides toward the drive screw, which is opposed to the rotation of the active screw. The threads of the active screw and the driven screw are reversible. The mutual coupling of the individual screws and the tight fit of the screws to the casing wall divide the inlet and outlet of the miniature diaphragm pump into one or more sealed spaces. As the screws rotate and interlock, sealed spaces are continuously formed at the suction end of the vacuum pump, sealing the liquid in the suction chamber, and sealed liquid continuously flows out of the suction chamber along the axial direction of the screw to the outlet end, just as the nut is continuously moved as the screw rotates, which is the basic principle of the miniature diaphragm pump.
