Operating principle of diaphragm pump (2)

  When the diaphragm 1 under high pressure, it will slowly move to maximum position of the stroke. Meanwhile, the compressed air will slowly enter into diaphragm 2 following space and impels the diaphragm 2 away the center body. The diaphragm 1 also will moves toward center body for these two diaphragm pumps are connected by one rod. The diaphragm 2 will extrude the medium and function on entry valve ball and seal up the suction pipeline through the water power. The water power also will function on exit valve ball and open the discharge pipeline. Meanwhile, exit valve ball of pump another side will shut down for pressure function, entry valve ball will open, then the medium will enter into the pump chamber.
  When one stroke finish. The compressed air will enter into diaphragm 1 following space again through reversing valve, simultaneously the diaphragm 2 following compressed air will discharge out through muffler.
