In any pneumatic conveying system, wind speed is a very important factor. Ensure that materials are correctly stored in the pipelineThe speed movement ensures that materials can be transported from storage or retrieval points to the destination or processing machine. If the material moves too slowlyOr the air velocity may be low, making it difficult to load the material. The material may be blocked at the bottom or bend.

    Reducing the air velocity during pneumatic conveying of materials may cause them to fall out of the airflow. In order to completeThe pneumatic conveying system must be carefully adjusted:

If the material is conveyed too quickly and the air flow rate is too high during the pneumatic conveying process, it may damage the material.

●If the conveyed material is soft and the speed is too high, it may have an impact on the material.

●If the material conveyed by pneumatic conveying is hard, it may produce breakage and dust.

●If the material is filled with glass and the flow rate is too high, it will wear down the pipes and bends.

●When pneumatic conveying heavier materials, a higher air flow rate may be required to ensure their normal flow in the airflow。

●Lower air flow rates may be required for pneumatic conveying of lighter materials to minimize their passageDegradation during pipeline operation.

    The shape and weight of materials in pneumatic conveying systems can affect the way they are transported in the airflow. These variables canChanges in air velocity are required to adapt to changes in material shape and packing density.

    Understand the material characteristics and flow characteristics through the pneumatic testing process and experience of these materials.

    The common material conveying speed can be fixed and set to the applicable standard value. Sometimes, the installation of pneumatic conveying systemsCalculate and adjust to meet the special requirements of heavier engineering resins. If the old system was designed for heavier resinsHowever, if the current design parameters are changed to lighter resins, the air flow rate of the pneumatic conveying system may be set too high.This may cause material issues such as dust, abrasion (soft materials), or pipe damage (glass filling materials).

    The pneumatic conveying system can adjust the air velocity of specific materials, and the vacuum pump can be adjusted according to the data of the blower manufacturerRecheck the blower curve and recalibrate the motor/blower speed ratio. Improved the overall efficiency of the pneumatic conveying systemBody efficiency reduces maintenance of pneumatic conveying system components.

    If appropriate conveying methods are used, the quality of the process can be maximized. In most cases, open-loop transportationEnough, no need to consider special requirements.

    However, when a material has dried and needs to be transported, some resins are very sensitive to moisture regain. In this caseThe pneumatic conveying process will benefit from closed-loop conveying or blowdown conveying systems. Maximum limit of a closed-loop pneumatic conveying systemReduce the exposure time of dry materials to the environment, from the time they are dried until they enter the processing machine. thingThe material is transported from the silo to the processing equipment using regenerated or pre treated air with a lower dew point than the surrounding airSource.

    The advantage of pneumatic conveying system is that it eliminates the surrounding air. Improve the quality of dry materials and reduce part defects. even ifEven the smallest amount of external air can contaminate this material. Closed loop pneumatic conveying system is used to be sensitive to moisture regain in a short period of timeThe sensory material must be included to prevent or minimize the possibility of moisture regain after drying.

    If a pneumatic conveying system requires a purging system, the size of the conveying pump must be carefully selected. We must considerThe time required for materials to be transported from the source to the destination. The size and capacity of the vacuum pump must be large enough to allow for trueThe "loss time" when an empty pump only transports material once in the pipeline and the remaining time (loss) when no material is transportedTime/loss of capacity).
