The flow of the pneumatic diaphragm vacuum pump is regulated by two "8" type rotors. The principle is that two "8" rotors (you can see the position change on the dial) undergo axial transformation through adjustable axis and sliding axis.
This motion is transformed into the radial displacement of the eccentric wheel through the inclined slot on the sliding shaft, and the piston is driven by the connecting rod. As a result of the change of piston stroke, the flow regulation is achieved. Pneumatic diaphragm vacuum pump how to adjust the flow and pneumatic diaphragm vacuum pump maintenance.
