How Does An Air Compressor Work? [Displayed In Animated Video]

People often wonder about how a compressor works. How air comes out of the hose in such a tremendous force. The mechanism is very simple. Let’s get start.The word “compressor” tells the meaning by itself. The compressor compresses air inside a tank that every compressor has. When the air is released, it comes out with great force. Source site Air Compressor Agency has dealt with this elaborately.

The engineering of compressing air is a little bit difficult. Before explaining, let’s get introduced with some basic parts of a compressor. There are three main equipment of a compressor.

  1. Pump
  2. Motor
  3. Air tank. 

Pump

How Does An Air Compressor Work?
Before knowing how pump works, let’s know what is inside the pump. There have the following parts: piston, connecting rod, crankshaft, cylinder and valve head. All are shrouded with cast iron cover.

The crankshaft is attached to the motor and helps it move up and down. With the movement of the crankshaft, the connecting road pushes the piston in the cylinder up and down. While the piston is moving, it takes a certain volume of air and sends to the air tank. This process goes on and a desired amount of compressed air is stored in the air tank.

Directly to the crankshaft, the connecting rod is attached and at the top of the connecting rod is the round shaped piston. The piston is inserted into a hollow cylinder. It is ensured that no air will leak when the piston will move upward and downward. A little leakage in this process will delay the main job of compressing air.

However, piston and cylinder are the main function of a pump. This pump can be either oil-lubricated or without lubrication. Lubricated tends to last longer than lubricant free pump. Contrarily, oil-free pumps are lighter and cheap in price compared to its counterpart. The drawback is that they create more noise than oiled pump.

Two-stage pump


How Does An Air Compressor Work?
In a two stage, there are two or three cylinders and obviously the same amount of piston. It is said that “One head is better than two heads”. The same applicable for the compressor’s pump. If one stage pump can fill up a 1-gallon tank in one minute, two stage pumps will take half of the minute.

Motor

The function of a motor is just to rotate the pump. A pump can’t rotate automatically. A pump’s function is compressing air and motor’s function is to rotate the pump. The power source of a motor can be either electric or battery. Battery powered compressors are very rare. Recently, Dewalt has brought a model named DeWalt DCC2560T1 FlexVolt 60V. California CAT-10020 is an electric powered compressor like many other electric compressors available in the market. Electric powered compressors are very popular among the users and 90 percent compressors sold are electricity powered air compressors.

Some air compressors are powered by generator where electricity is not available. Industrial air compressors are operated by oil engine; they don’t need electricity. 

Tank

How Does An Air Compressor Work?
Every air compressor has a tank that stores air at high pressure supplied by the pump. The more the size of a tank, the greater amount of air can be stored for use. Cast iron and aluminum made tanks are usually available in the market. Cast iron is stronger and heavier than aluminum built tank but cast
iron tank rust frequently if proper care is not taken.

Air Compressor For Spray Painting (Review With Video)

Most everything I built in my garage gets sprayed. You can purchase a small compressor for around $100. A rotary screw which starts at about $4,000. For my small garage workshop, I needed to purchase the best compressor for the least amount of money. The HVLP spray gun manufacturer recommends a three to five horsepower compressor. If you're in the market for a new compressor, the real measurement you should be looking at is the CFM, that's Cubic Feet Per Minute of air delivery. Many of the air tools you may want to use can require up to 20 CFM at maybe 60 PSI. Campbell Hausfeld Air Compressor So, we really should shop for CFM per dollar not horsepower or pressure. Also, when I purchase Campbell Hausfeld Air Compressor, 26-gallon Vertical Oil-free (DC260000), I didn't have the advantage of being able to look at the internet ratings. This compressor has a rating of 4 CFM @ 90 PSI (Pounds Per Square Inch) and once I start spraying it runs continuously. It...
