In this tutorial I will show you how to make an air pump from a simple DC motor and using a number of commonly available materials.
How To Make Homemade Air Pump
This is a portable air pump made from very common hardware. The body of the air pump is made from a gallon cap. Using an old bicycle tire tube creates a check valve that only allows air to move in one direction. The diaphragm is made of a balloon and the clip is made using two SIM card holders cut into circular shapes and glued together with the balloon inserted between them.

The outlet is made using a pen tube and glued to the pump body. The pump is powered by a Speed 545 DC motor and an old lithium polymer cell from a laptop battery.
The body of the air pump is made from a plastic cap that I removed from a gallon. The first eight entry holes are drilled at equal distances, each with a diameter of 10 mm.
To pump air in the desired direction, it is necessary to force the incoming air in the desired direction. This can be achieved by using a check valve. As the name suggests, without a check valve, air can only move in one direction.
In this case, we will use a rubber washer cut from an old bicycle tire tube. The washer is then screwed inside the cap so that air can only be drawn into the cap through the eight inlets as the piston expands the internal volume of the suction cavity. As the piston moves so that the volume of the chamber decreases, the air inside the cavity forces the rubber washer against the wall of the cap, allowing air to move only through the outlet, thus pumping the air in the desired direction.

There are imperfections on the front of the cover that need to be addressed. Then the face of the cover is smoothed with sandpaper.
The air outlet is located on one side of the cover. First, a 10 mm hole is drilled in the cover. we used the body of an old pen for the output tube, which fits the 10mm hole perfectly.
The exhaust pipe is then glued to the cap, making sure no air leaks through the joint.
The pusher is made of two spare SIM card holders. These cards are made from almost 1mm thick plastic sheet, so any close alternative can be used to make the air pump piston.

Cut two circles slightly smaller in diameter than the suction cavity/cap.
The diaphragm in the pump allows an air gap to be created as the piston moves back and forth. The diaphragm is made of a balloon. The two circular panels are then glued to the balloon, pressing the balloon between them.
Then a hole is drilled in the center of the piston, which is then fixed with the nut that we got with the bicycle tire stems. The nut is washered on each side of the piston and then taped to ensure air leakage during air pump operation.
The piston, along with the balloon diaphragm, was then glued to the suction cavity/cap using super glue, stretching the balloon to prevent wrinkles around the piston. Later, the extra edges of the balloon are cut off with a sharp razor.

Later, four rubber pads are glued to the bottom of the MDF sheet, which act as feet for the base and prevent it from moving when the pump is running due to vibration.
We made a sheet of 5 mm thick fiberglass with a diameter of 20 mm for the piston to move back and forth. The pulley has a central hole for attaching the motor, and the second hole is used as a holder for the connecting rod, which is connected to the piston. The character is made from a bicycle tire stick. The metal rod is screwed onto the piston nut. The other end of the stick is bent at a 90 degree angle.
The engine has a crank pulley that is simply glued to the engine shaft. Then the rod is attached to the crankshaft pulley, and the other end is bent so that it does not slip off the pulley during movement.
The motor is then attached to the MDF base plate using a wooden bracket. The motor is then glued to the bracket.

The battery is made of a single lithium polymer cell with a voltage of 3.7 V and a capacity of 2200 mAh. This cell was extracted from an old laptop battery.
The battery is then connected to the motor via a switch to operate the pump as desired. The battery and switch are hot glued to the base plate.
The final results are good. The way it was done in the end seems creative, as most of the materials used to make this air pump are common household items.
To demonstrate the operation of the air pump, I attached a rubber tube to the outlet of the air pump and immersed it in a container filled with water. When the switch is on, the end of the tube begins to bubble very quickly. The air pump was invented by Robert Boyle and Robert Hooke. It is a pump that is installed in bicycles, an aquarium, a gas compressor, an air signal and a vacuum cleaner for pumping air.
How To Rebuild An Air Compressor Pump
The usual mechanism that goes into an air pump is that some of the air is pushed out and a vacuum is created that fills in more air.
It is basically used to push air. The air pump on different tools and equipment works exactly the same except for very small differences.
There are two categories of air pumps: diaphragm pumps and piston pumps. The way these two types of pumps work differ, they are installed in different machines and used for different purposes.

How To Manually Generate Oxygen In Aquariums
A. An air pump is used in various machines to push air. For example, it is used in an aquarium to diffuse oxygen into the water, not just on the surface of the water. In bicycles and other vehicles, it is used to fill inflated tires with air.
A. The air pump has a piston and two valves. One of the valves connects to the vehicle to be inflated, while the other valve takes in air from the outside. Thus, when the pump is raised up, the pressure is reduced by drawing air from the outside, and when the pump is pushed down, air is pushed into the tire.
A. There is very little difference between a compressor and a pump. An air pump moves air/gas from one place to another. The compressor compresses the gas into a smaller volume and at the same time pumps it elsewhere.
A. There are two types of pumps: reciprocating pumps and rotary pumps. An example of a reciprocating pump is a bicycle, while an example of a rotary pump is a washing machine.

Air guns are pretty good because they rely on increased air pressure to propel the bullets. You can buy them at the store, but they can be expensive. Fortunately, you can make one very cheaply. If you can find stuff at home, you can do it for free!
