What are the 17 key points of pneumatic conveying system design?

In the process of designing and conceptualizing a pneumatic conveying system, it is necessary to fully combine and analyze the initial conditions of the design concept, such as material characteristics, basic parameters of conveying conditions, etc., to determine the type of pneumatic conveying system, and to determine the layout of conveying pipelines and their basic elements such as conveying volume, mixing ratio, and airflow velocity. As a highly automated and precisely controlled conveying system, the force conveying system needs to consider multiple key factors comprehensively in the design and implementation process. If one factor is not properly considered, it may lead to low operational efficiency of the entire system, or even the inability to meet process requirements. Next, we will introduce the 17 key points of pneumatic conveying system design with the guidance of environmental protection:

1. The pneumatic conveying system technician also needs to analyze the initial design conditions.

The initial condition includes the material characteristics involved in the pneumatic conveying system, basic parameters of the conveying condition, etc. In addition, flammable and explosive materials require stricter and more careful handling.

2. Determine the type of pneumatic conveying system.

Based on the basic parameters of the initial condition, such as material characteristics, determine whether the conveying type is positive pressure conveying, negative pressure conveying, or mixed conveying.

3. Determine the layout of the conveying pipeline.

At the same time as determining the layout of the conveying pipeline, it is also necessary to determine the structural types of the main components and draw a system layout diagram, avoiding obstacles on site as much as possible according to customer requirements. And it is also necessary to ensure the operation of the pneumatic conveying system.

4. Determine the conveying capacity

Calculate and determine the conveying capacity design of the pneumatic conveying system based on the annual conveying volume, annual operating days, work regularity, and various types of process configurations of the enterprise.

5. Determine the mixture ratio of raw materials and gases.

The material to air ratio refers to the influence of the specific gravity of materials and air during the material transportation process.

6. Determine the airflow velocity for material transportation.

What type of Roots blower, centrifugal blower, or other gas source is needed to affect the airflow velocity!

7. Calculate the amount of air required to be conveyed by the pneumatic conveying system.

8. Calculate the diameter of the conveying pipeline.

11. Select the type and capacity of the pneumatic conveying system fan based on the required conveying air volume, total pressure loss, and related design conditions.

12. Choose the type and capacity of the motor.

13. Determine the required motor equipment and ancillary equipment.

14. Determine the start stop operation sequence, interlock safety devices, and determine the type and capacity of the control panel.

15. Determine the specific location of the suction and exhaust ports, whether to add noise reduction devices, and determine the dust removal measures.

16. Develop installation, debugging and operation procedures.

17. Prepare the types and quantities of vulnerable parts and spare parts required.
