The selection of fans is crucial in the pneumatic conveying system of industrial alumina powder. The following is a fan selection guide based on a comprehensive consideration of multiple factors:
1、 Selection of Air Volume and Wind Pressure
1. Airflow:
Calculate the required air volume based on the conveying volume of alumina powder, pipeline diameter, and conveying speed. Ensure sufficient air volume to ensure stable flow of alumina powder in the pipeline.
2. Wind pressure:
Calculate the required wind pressure based on factors such as pipeline length, number of bends, and valve resistance. At the same time, margin needs to be considered to ensure that the alumina powder can reach the target position smoothly.
2、 Matching of speed and power
1. Speed:
A higher rotational speed usually means greater air volume and pressure, but it can also increase power consumption and noise. Therefore, when choosing the speed, it is necessary to weigh the actual needs.
2. Power:
The selection of power should match the air volume, air pressure, and system efficiency. Ensure sufficient power to meet transportation needs while avoiding excessive energy consumption.
3、 Selection of structural types
1. Three leaf Roots blower:
2. Compared to a two blade Roots blower, a three blade Roots blower has smaller exhaust pulsation, lower noise, and smoother operation. Therefore, it is more suitable for pneumatic conveying of alumina powder.
4、 Control system and additional functions
1. Variable frequency speed regulation:
By adopting a variable frequency speed regulation system, the fan can achieve stepless speed regulation, adjust the air volume and pressure according to actual needs, and improve system efficiency and energy-saving effect.
2. Remote monitoring:
Set up a remote control system that can monitor the real-time operation status, fault alarms, and other information of the fan, facilitating remote management and maintenance.
3. Protective function:
Set up protection functions such as overvoltage, undervoltage, overcurrent, overload, etc. to ensure that the fan can automatically shut down in case of abnormal conditions, preventing damage and accidents.
5、 Other considerations
1. Pipeline design:
Reasonably design pipeline layout and diameter, reduce the number of elbows and valves, lower pipeline resistance, and improve transportation efficiency.
2. Dust removal device:
Install a dust removal device at the end of the conveying system to separate the alumina powder from the transport airflow and avoid dust pollution.
3. Maintenance and upkeep:
Regularly maintain the Roots blower, check the wear of bearings, gears, and other components, replace damaged parts in a timely manner, and ensure the long-term stable operation of the blower.
In summary, the selection of industrial alumina powder pneumatic conveying fans needs to comprehensively consider multiple factors such as air volume, air pressure, speed, power, structural type, control system, and additional functions. Through scientific and rational selection, an energy-saving and stable pneumatic conveying system can be achieved. When making specific selections, it is recommended to consult professional fan manufacturers or technicians to ensure the accuracy and reliability of the selection.
