An air pump works by mechanically compressing or moving air to "transfer" it where it's needed. Its specific functions vary by application scenario:
1. Inflation & Pressurization
Inflating tires (car, bicycle, e-scooter), balloons, air mattresses, swimming floats, etc.
Recharging air springs, pneumatic suspension, and accumulators to maintain a set pressure.
2. Gas Delivery (Pneumatic Conveying)
Aerating fish ponds and shrimp tanks in aquaculture.
Aeration in wastewater treatment plants (supplying oxygen to microorganisms).
Pneumatic conveying: using airflow to move powders and granular materials.
3. Vacuum & Negative Pressure
Vacuuming: vacuum packaging for freshness, medical suction devices.
Vacuum gripping: mechanical grippers and suction cups to hold workpieces.
4. Providing Power (Pneumatic Control)
Driving cylinders, pneumatic valves, and pneumatic tools (air drills, spray guns).
Pneumatic actuators in industrial automation production lines.
5. Cooling & Dust Removal
Cooling electronics and engines.
Blowing away dust and debris.
6. Medical & Daily Life
Supplying air for blood pressure monitors, ventilators, and nebulizers.
Aquarium aerators and alternating-pressure air mattresses.
