In pneumatic conveying, the air source serves as the core equipment of the entire system, providing power to ensure the effectiveness and reliability of the conveying process. Due to the varying methods of conveying, different application sites, and distances, the properties of the materials being conveyed are diverse, thus necessitating different power sources and principles for pneumatic conveying.

Common gas source equipment includes air compressors, Roots blowers, Roots vacuum pumps, centrifugal fans, etc. When selecting the type of equipment to serve as the power source for the system, consider the following aspects:

According to the conveying conditions, fully meet the required air volume and pressure: due to the changes in the physical properties of the conveyed material, changes in environmental climate and humidity, and the wear and tear of the equipment used, the function of the pneumatic conveying system may decline; therefore, when selecting the air source, the air volume and pressure calculated by the design should have a certain margin.

2. Changes in pressure will also affect the air volume; drastic changes in air volume due to pressure fluctuations can cause pipeline blockages when the internal velocity decreases; conversely, an increase in internal velocity will raise the pressure required for conveyance, accelerating pipeline wear and material breakage; as the working range of the pneumatic system is wide, the pressure required for conveying is several times more than that for pure air flow, thus ensuring the motor does not overload.

The sensitivity to dust should be minimized to prevent fine particles from entering the gas source equipment and causing gas malfunctions.

4. For positive pressure pneumatic conveying system air source equipment, it is essential to minimize oil and moisture content in the exhaust; for pneumatic conveying devices used in chemical industries and food conveying, due to the strict prohibition of oil content in the air, a negative pressure pneumatic conveying system should be adopted, and centrifugal fans, Roots vacuum pumps, or oil-free reciprocating air compressors can be chosen. In all cases, air filters and oil-water separators must be used to eliminate oil, moisture, and dust in the air as much as possible.

5. Durable and reliable in operation;

6. Types and properties of the conveying medium used: temperature, humidity, corrosiveness, suction pressure, lubrication conditions, etc.

7. Installation location, ground bearing capacity, area, height restrictions, surrounding temperature, and installation access conditions, etc.

8. Operations Management Controls and Monitoring: Automated Control, Remote Control, On-site Control

9. Compliant with environmental protection requirements and noise restrictions.

The selection of air conveying system's air source equipment is complex, requiring high standards for air volume, pressure, and velocity. Incorrect selection can lead to failure in conveying or even damage to the equipment. Therefore, professional personnel are needed for the selection.
