1.Pneumatic conveying systems: Air compressors play a central role in pneumatic conveying systems, transferring bulk materials from one location to another through compressed air. Pneumatic conveying systems can be either positive pressure conveying (pressure conveying) or negative pressure conveying (vacuum conveying).

2.Positive pressure conveying: In the positive pressure conveying system, the air compressor provides compressed air to push the material from the starting point of the conveying to the end point. This system is suitable for long-distance, high-volume material transportation, such as cement, grain, chemical raw materials and other industries.

3.Negative pressure conveying: The negative pressure conveying system uses the negative pressure generated by the air compressor to suck the material into the pipeline from the starting point and convey it to the end point. This system is suitable for conveying short distances, especially for materials that are prone to dust and contamination such as food powders and pharmaceutical raw materials.

4.Compressed air purification requirements: In the process of pneumatic conveying, the purity, oil content and humidity of compressed air will directly affect the safety and stability of material transportation. Therefore, the air compressor needs to meet certain purification requirements, such as separating moisture, removing grease, filtering solid particles, etc.

5.Air pressure and flow requirements: Air compressors need to meet the high pressure and flow requirements of pneumatic conveying. The specific values of pressure and flow will vary according to the characteristics of the conveyed material, the conveying distance, the conveying height, the diameter of the conveying pipe, and other factors.

6.High efficiency and low energy consumption: Pneumatic conveying requires multiple processes such as compression, acceleration and conveying of materials, so air compressors need to have the characteristics of high efficiency and low energy consumption. Energy-efficient compressors should be selected to reduce overall operating costs.

7.Intelligent control requirements: The control requirements of air compressors for pneumatic conveying are complex, so it is necessary to choose an air compressor with intelligent control functions. The air compressor should automatically control and adjust the pressure in the conveyor pipe to ensure normal and stable material transportation.

Air compressors play a vital role in material handling, not only providing the necessary power, but also improving conveying efficiency and safety through intelligent control.
