Pneumatic diaphragm pump installation and precautions

    Pneumatic diaphragm pump working conditions are strong, for example, in the harsh site of the center, such as construction sites, industrial and mining wastewater discharge, due to the impurities in the sewage and complex composition, the pipeline easy to infarction, so that the electric pump to form a high load Environment, motor heat vulnerable. Pneumatic diaphragm pump through the particles and adjustable flow, the initiative to stop the pipeline when the infarct. Because of its strong advantages, the installation of pneumatic diaphragm pump and matters needing attention is very necessary.

    First, the pneumatic diaphragm pump specific installation process:

    1, check the diaphragm pump before operation:

    Before working on the diaphragm pump, inspect all fixings to prevent slackening. Tighten the loose parts to avoid leakage. Secure the diaphragm pump with the method described in the attached card.

    2, diaphragm pump intake and start:

    When activated, the air valve opens about 1/2 to 3/4 turns. After the pump is started, open the air valve to increase air flow to achieve the required flow rate.

    3, pneumatic diaphragm pump after use:

    If used to transport easily curable materials, to prevent damage to the pump, thoroughly clean the pump after each use.

    Second, the installation of pneumatic diaphragm pump Note:

    1, the suction pipe and the discharge pipe diameter configuration:

    (1) The suction pipe diameter of not less than the pump inlet port diameter, such as the delivery of high-viscosity fluid, the suction pipe diameter is preferably greater than the pump inlet diameter. Suction piping on the inlet side must be durable and free of wrinkles to create a high vacuum condition.

    (2) The diameter of the outlet pipe should be at least equal to the outlet diameter or slightly larger to reduce the friction loss. All piping and fittings must be leak-tight or pump self-priming will be reduced.

    2, diaphragm pump installation location, height, piping layout, gas supply and other matters:

    Pneumatic diaphragm pump installation: If you ignore the installation details, a long period of careful planning, research and selection will still result in poor pumping and affect the life of the pump.

    (1) Location: Noise, safety and other logic often require that the equipment be installed. Parallel installation with conflicting requirements may result in blockage in the area of ​​use, affecting the installation of other pumps.

   (2) Use: First, the location of the pump must be easy to use, so that maintenance personnel will facilitate routine inspection and commissioning.

   (3) Air supply: Each pump should have a vent pipe, and the vent pipe should be able to provide enough air to achieve the desired pump flow. Air pressure according to different pumping needs, but not more than 7BAR.

   (4) Installation height: Please take full account of pump self-absorption capacity to avoid self-absorption to reduce the problem.

   (5) Piping: The pump position can not be finalized until after considering each possible location of the piping problem.

   The use of such products as pneumatic diaphragm pumps needs more attention, but the preparation of these matters can provide good protection for the use of the products. As its position in the pump industry continues to improve, its research is even more important.
