Air Compressors

Air compressors are machines that can convert electrical power into kinetic energy, precisely by utilizing the compressed air. When the compressed air is let loose in a quick burst, it can release enough kinetic energy that can be stored for some purposes, such as air transfer, pneumatic device activation, and other cleaning operations.

The device converts power by using an electric motor which may be diesel or gasoline powered. The result is potential energy, and it is stored as pressurized air. By one of quite a few methods, the air compressor forces more air into the storage tank, thereby increasing the pressure. The air compressor goes off when the tank pressure gets to its upper limit. The compressed air is held in the tank until it's needed. When the kinetic energy is released or being used, the tank depressurizes. Once the tank pressure gets to its lower limit, the machine turns on again and it re-pressurizes the tank. We have a great range of these available today in .

Air compressors operate in two phases;

  1. The compression operation
  2. The release operation

The most prevalent kinds of air compressors are diesel/gas or electrically powered compressors. The compressor’s power is measured in Horsepower and cubic feet of air. The gallon size of a tank shows you the amount of compressed air is available on reserve. The diesel/gas powered compressors are commonly used in remote areas who have reduced access to electricity.

They can be noisy and also require ventilation for their exhaust gasses. The electrically powered compressors, on the other hand, are used in workshops, factories, and garages that have permanent access to electricity. The regular workshop/garage compressors range from 110-120 Volts, or they may be 230-240 Volts. Most compressor tank shapes are: “twin tank”, "pancake", "horizontal", and "vertical". The shape depends on the size and purpose.

Air Compression Methods

  1. Positive-displacement compressors

These types used mainly by hobbyists, and in small-scale applications as well as industrial-scale applications. However, other types, such as the rotating impeller compressors may be used as well. The positive-displacement compressor principally relies on a part of the machine performing the intake of air and minimizing the quantity of space in the tank while pressurizing the air molecules. As the air is released, the valve opens, and compressed air rapidly discharges.

  1. Piston-type compressors

These are fairly common, and they utilize the motion of a piston and use it to introduce air into the chamber using an intake valve. The automotive-type piston is an example of this type. The automotive-type piston comprises of a crankshaft which is connected to a rod and is topped by one cylinder inside another cylinder.

The base of the crankshaft revolves in a tiny circle. The connecting rod stays in a fixed position, but it functions in a hinged way with the cylinder and allows the cylinder to remain horizontally or vertically oriented at all times. The rod releases the cylinder when the crankshaft reaches its lowest revolution point. When the crankshaft turns, the rod rises and pushes the cylinder up. The constant motion continues an up-and-down trail for the cylinder and permits air intake and release.

There is an inlet port on the exterior cylinder and an outlet port as well as two valves stored in three chambers. The first chamber is called the inlet chamber; the other chamber is known as the outlet chamber. Between these two chambers is the piston’s cylindrical chamber. When the piston rises, its inlet port doesn’t allow air to go back to the inlet chamber, so air travels through the outlet valve and into the outlet chamber. This process repeats and forces more air into the outlet chamber and causes more compression.

The other positive-displacement compressors utilize a different technique of compressing the air chambers.

  1. Rotary screw compressors

They create an air chamber amid helical screws and their housing. As the screws turn, the volume of the air chamber, compressing the air amid the screws. The Vane compressors comprise of a slotted rotor inside a slator. Due to the blade orientation built on the rotor, its revolution pushes air into the chamber and compresses the volume with every subsequent blade rotation.

A lot of positive-displacement compressors make use of oil as a lubricant for their compressor motion and a solid seal for compressed air.

  1. Centrifugal compressor

This is an example of non-positive-displacement compressors, and it uses dynamic compression to function. The centrifugal compressor spins its impeller, a kind of rotor, to fast-track the air within, and use a diffuser to reduce the speed the air. The deceleration makes pressure on the air to increase. The air heats up during this process and has to be cooled by the intercooler.

Uses of Air Compressors

Air compressors are used both commercially and industrially. Usually, commercial air compressors are built to function with various tool attachments to provide pneumatic power effectively. Some electrical devices that use the air compressor include nail guns, blowguns, air staplers, spray guns, air sanders, and sandblasters. The tools typically have industry standard attachments since they need to be hooked up to different air compressor brands for diverse purposes. Air compressors are also used to fill up tires and some other items with air.

The industrial strength air compressors, on the other hand, are used to power up industrial tools just like commercial varieties. However, they may also be used in powering larger machines as well as applications. For example, petroleum is often “coked,” after carbon particles called coke are brought in to change the behavior for efficiency reasons. Air compressors also power this process.
