Product Description
1. Manufacturing Industry
- Workshop Ventilation and Air Exchange: Removing dust and odors.
- Equipment Heat Dissipation: Cooling of motors, machine tools, etc.
2. Energy Industry
- Thermal Power Plants: "Air Supply" for boilers (providing air required for combustion) and "Induced Draft" (discharging flue gas).
- Nuclear Power Plants: Ventilation systems.
3. Chemical Industry
- Transportation of Corrosive Gases: E.g., treatment of hydrochloric acid mist.
- Gas Agitation for Reactors: Explosion-proof fans are required.
4. Environmental Protection Field
- Sewage Treatment: Delivering air into sewage via "aeration fans" to supply oxygen for microorganisms and promote organic matter degradation.
- Air Pollution Control: Gas transportation for dust removal systems (e.g., baghouse dust collectors) and flue gas circulation for desulfurization and denitrification equipment.
5. Livelihood and Construction Field
- Building Ventilation: Fresh air systems for central air conditioning in office buildings and shopping malls; exhaust systems for underground parking lots.
- Household and Commercial Use: Fans for indoor and outdoor units of household air conditioners, exhaust fans for range hoods, and air curtains (for temperature insulation and dust prevention at shopping mall entrances).
6. Special Scenarios
- Ventilation for Subways/Tunnels: Smoke exhaust in case of fire.
- Aerospace: Air circulation in aircraft cabins.
- Medical Equipment: Gas delivery components for devices such as ventilators.
1, Core Working Principle of Fans
1. Suction Process
2. Energy Conversion Process
3. Discharge Process
1. Air Volume Flow Rate
2. Air Pressure
3. Total Pressure Efficiency
- The efficiency of mainstream industrial fans is mostly 70%~90%, and high-efficiency fans (such as centrifugal fans with optimized impeller profiles) can have an efficiency of over 90%.
- Efficiency is significantly affected by "operating condition deviations": if the actual air volume deviates from the designed air volume by more than ±10%, the efficiency will decrease significantly (e.g., for a fan with a designed air volume of 10,000 m³/h, if the actual operating air volume is only 5,000 m³/h, the efficiency may drop from 85% to below 60%). Therefore, it is necessary to select fans with a "wide high-efficiency range" to adapt to fluctuations in operating conditions.
4. Shaft Power and Motor Power
- Shaft Power: The power required to be input to the fan's main shaft (the power consumed by the fan itself). The calculation formula is: "Shaft Power = (Air Volume × Total Pressure) / (3600 × Total Pressure Efficiency × Mechanical Efficiency)" (mechanical efficiency refers to the energy loss of bearings and transmission components, usually ranging from 0.95 to 0.98).
- Motor Power: The rated output power of the supporting motor, which needs to be 10%~20% higher than the shaft power (to reserve a safety margin) to prevent motor overload during fluctuations in operating conditions.
Common Units: kW (for small and medium-sized fans), MW (for large power station fans).Characteristic Description: Power is positively correlated with air volume and air pressure - as air volume or air pressure increases, power rises significantly (e.g., if the air volume doubles, the power approximately doubles). Therefore, methods such as frequency conversion adjustment should be adopted to avoid energy waste.
