Normal shutdown process of axial flow fan with standardized interface

Release Time：2021-07-20

Axial fans have many familiar dimensions and standardized interfaces, which make it especially easy to switch to our lightweight fans. Use these fans for ventilation and point cooling of internal mechanical parts in areas with limited space. They are computers, photocopiers, Ideal for electronic instruments, crankshaft flow machine tool products and solar energy systems.
The tube shaft fan is designed to meet various requirements from general ventilation to process air supply. The installation flexibility makes it ideal for many industrial and commercial applications. The unit can be driven directly or belt. The axial flow fan has fixed or adjustable blade spacing. Steel or aluminum wheels.
This fan is designed for applications that require large amounts of air at moderate to high pressures. Direct and belt drive models are available with fixed and adjustable impellers. Tubular design and high wheel efficiency provide optimal performance while minimizing space.
Axial fans are usually used to exhaust dirty air or smoke from processes (such as paint spray booths), supply fresh air, and general on-site cooling of personnel, rooms or machines. They are usually designed to handle large amounts of air at low pressure. Axial fans are usually used in direct drive models, propellers are mounted on the motor shaft, and belt drive models. The material used for industrial axial fans is usually low carbon steel, however, some applications may require aluminum propellers or all aluminum for fireproofing, stainless steel or coating for chemical resistance, and axial fans. Some applications may also require the fan to be belt-driven outside the airflow without being affected by air flow conditions, such as high temperatures, excessive dirt, or corrosive contaminants.

Normal shutdown process of axial flow fan.
1. Press the explosion-proof switch to stop pressing the button of the axial flow fan, move the handle to the power failure position, and "lock" to cut off the power supply of the local fan motor and stop running.
2. If the operation of the local fan must be stopped due to failure or other reasons, the work at the air supply site of the local fan must be stopped immediately, the personnel must be evacuated, the fence must be set up, the warning sign of "no entry" must be hung up, and the mine leader on duty must be reported.
3. In the tunneling work site using local fan ventilation, temporary shutdown is not allowed to stop the wind to avoid tile accumulation. If the wind stops, the axial flow fan must set up the fence, reveal the warning mark, and "lock" the explosion-proof switch ".
