Diaphragm pump flow is adjusted by rotating the adjusting mechanism to adjust to change the piston stroke. The principle is: the hand wheel rotation adjusting mechanism (you can see the position change of the dial), through the adjustable shaft and the sliding shaft axial transformation, the motion of the sliding chute transition shaft is radial displacement of the eccentric wheel, through the connecting rod pushes the piston, the piston stroke of the change, so as to achieve the purpose of regulating the flow of objective.
