The pneumatic conveying system uses compressed air as power, and materials are conveyed in sealed pipelines under the action of airflow. With the rapid development of the economy, this dust-free conveying method is also constantly evolving, and pneumatic conveying technology is constantly improving. The materials conveyed are becoming more and more extensive, and morePneumatic conveying manufacturerAfter years of exploration, the factors that affect the performance of pneumatic conveying have been summarized as follows:

1、 Erosion loss

    Hard gravel like materials can quickly wear down components of pneumatic conveying systems, especially in the pipelines used for elbow feeding. Wear occurs through impact, especially at high speeds, and wear occurs through the friction of particles sliding on the surface. This occurs in both dilute phase pneumatic conveying and dense phase pneumatic conveying. The rotor top of the rotary valve is particularly susceptible to wear, and severe wear can cause air leakage. When air leaks, the amount of air reaching the conveying pipeline will decrease, causing blockages in the pneumatic conveying system. If the pneumatic conveying filtration system is not regularly cleaned and maintained, materials will enter the fan, reducing its lifespan.

2、 Material damage

    A large amount of energy is generated during the pneumatic conveying process, which can decompose materials beyond what is necessary or required. Collisions and friction with materials such as pipelines can cause damage to the materials, especially when they are fragile. This not only reduces the quality of the material, but also generates fine powder that cannot be used by the pneumatic conveying system. Due to the high material velocity in dilute phase pneumatic conveying, the material is suspended in the air and does not pass through the surface of the pipeline. Therefore, conveying to the dense phase can solve some of the material degradation problems. If dilute phase transportation is a feasible option, reducing the number of bends in the pipeline will reduce impact and minimize material damage.

3、 Condensation

    Condensation is a common cause. In some cases, when the factory is running, the temperature increases significantly during the day and decreases at night. These temperature changes can cause condensation, and the substance will absorb, leading to condensation or sticking. The micro heating or insulation part of the pipeline can help prevent this problem. Alternatively, as this issue typically occurs during start-up, blowing air into the pneumatic conveying pipeline for a short period of time before use can dry the pipeline. If none of these solutions are applicable, then an air drying system is needed.

4、 Dust

   The pneumatic conveying system is completely enclosed, which helps reduce dust issues. Dust has caused significant harm to factories in many different industries. Long term and frequent exposure to any type of dust can often pose health and safety hazards, ranging from lung problems, skin problems to fires and dangers. Substances that appear harmless on the surface, such as flour, have caused multiple explosions It is crucial to control the dust inside and around the pneumatic conveying system. There are special hazards at the inlet and outlet of pneumatic conveying systems. Pneumatic conveying systems often work with materials that are prone to generating dust, which accumulates around belts, bucket elevators, hoppers, and other equipment at both ends of the conveyor. The dust collection system at these locations is essential.

5、 In addition to dust, eliminating sources of ignition is also crucial. Electric arcs between faulty lines are a common cause of fires and explosions. Regular maintenance, inspection, and necessary replacement can help prevent this situation from happening. The correct design of pneumatic conveying system can help maintain smooth and safe operation of the factory.
