The working principle of the diaphragm pump: the motor drives the worm through the coupling and the worm gear speeds up to make the main shaft and the eccentric wheel rotate, and the eccentric wheel drives the tappet to reciprocate in the guide cylinder. The diaphragm pump works by adjusting a certain stroke to form a continuous pressure and quantitative discharge of liquid, relying on the back and forth agitation of a diaphragm to change the volume of the studio to inhale and discharge liquid.

The cam is hinged to one end of the driving shaft, and the other end of the driving shaft is connected to the diaphragm assembly. The rotating shaft is driven to rotate by a motor, which drives the three cams to rotate and the driving shaft to reciprocate, thereby driving the agitation of the diaphragm assembly, thereby realizing the synchronous conveying of medium by the three pump head units.

[0007] Furthermore, the three pump head units are arranged on the pump head cover along the same line.

[0011] Furthermore, the feed valve and the discharge valve are both one-way valves.
