What does an air pump do?

An air pump is a device that increases the pressure of air. It can be used to fill balloons, tires, and other inflatable objects, or to move air from one place to another. Air pumps come in a variety of shapes and sizes, and can be powered by hand, electricity, or gasoline.

Here is a more detailed explanation of how an air pump works:

1. The pump has a chamber that is sealed off on one side.

2. A piston or diaphragm moves back and forth inside the chamber, creating a vacuum.

3. Air is sucked into the chamber through a one-way valve.

4. The piston or diaphragm then moves in the opposite direction, compressing the air and forcing it out of the chamber through another one-way valve.

The pressure of the air that is pumped out of the air pump depends on the amount of force that is applied to the piston or diaphragm. The greater the force, the higher the pressure.

Air pumps are used in a variety of applications, including:

* Inflating tires

* Filling balloons

* Blowing up pool floats

* Aerating fish tanks

* Cleaning dust and debris from surfaces

* Moving air from one place to another

Air pumps are a simple but versatile tool that can be used for a variety of purposes.
