The pneumatic logistics fan runs overtime.

1. First of all, the output time of gas-ash mixture in the conveying equipment of pneumatic conveying system is determined by calculation, so it is necessary to check whether the calculation result is correct.

2. Secondly, the gas-ash mixture in the sending equipment is conveyed to the conveying pipeline, and the material is conveyed by using the pressure of the sending equipment and the pressure difference inside the pipeline.

3. Finally, the pressure in the pipeline to be transported is less than the pressure of the sending equipment, and the pneumatic logistics fan runs overtime.
