Common Problem
  • What is the reason for the slow working rhythm of pneumatic diaphragm pumps

    Explanation: If the air source pressure is too low, in addition to the air compressor itself, the distance between the air pipes should be shortened as much as possible, because if the air pipe is too long, compressed air will be consumed and the actual air pressure will not meet the rated requirements.

  • How to extend the service life of pneumatic diaphragm pumps

    Explanation: Install the pneumatic FRL, keep the air source pressure within the normal range; keep the feed inlet unblocked, do not install valves; Clean the pump with clean water every time the pump is finished, especially when pumping relatively viscous or viscous materials.

  • What is the reason why the pneumatic diaphragm pump is ventilating, but cannot suck up the material

    Explanation: In this case, the wear of the ball valve may lead to poor sealing of the ball valve and the ball seat, requiring replacement of parts. In addition to the cause of wear, check whether there is any air leakage in the feed pipe. If air enters the feed pipe during the operation of the pump, the pump will not be able to suck materials.

  • What is the reason why the new pneumatic diaphragm pump does not work after installation and ventilation

    Explanation: During the express delivery process, the slider inside will shift and need to be reset manually. The specific operation method is as follows: Open the air valve cover, move the two small black sliders back and forth, one on the left and the other on the right, and then install the air valve coverThere is no need to tighten the air valve cover screws too tightly

  • What is the necessity of installing a pneumatic triplex at the air inlet of a pneumatic diaphragm pump?

    Explanation: Compressed air contains impurities and moisture. Over time, the impurities will accumulate more and more in the valve chamber, which will wear the V-ring and O-ring inside, causing the pneumatic diaphragm pump to not work; adjust the intake pressure to avoid Excessive pressure damages the diaphragm; the added oil can lubricate the valve chamber.

  • Several common causes of diaphragm damage in pneumatic diaphragm pumps

    Explanation: The pressure of the air source is too high, which causes the diaphragm to be broken; the inlet is blocked or the valve is installed, which causes the vacuum in the pump cavity to cause the diaphragm to rupture.
