Compressed air is present all around us, you use it for example when you inflate a balloon or the tubes of your bicycle. In this article, here is an explanation of what compressed air use to be and the way it is been created. To study more regarding air generally, please read this introductory article.
Compressed air: Definition
While you understand it or not, compressed air happens to be involved in every characteristic of your life, from the birthday balloons at a party to the air in the tires of cars and bikes. Compressed air was probably even used to make the phone, tablet, or computer you are using right now to read this article.
The main ingredient in compressed air is, as you may have already guessed, air. Air is a gaseous mixture, ie composed of several gases. These are mainly nitrogen (78%) and oxygen (21%). It is made up of different air molecules that each have a certain amount of kinetic energy.
Take the example of a balloon. When you inflate a balloon, the air forcibly enters a smaller volume. The energy contained in the compressed air inside the balloon is equal to the energy required to inflate it. When you will open the balloon and the air is released, it dissipates that energy and makes it fly away. This is also the principle of a positive fluid-aire dynamics displacement compressor.
Compressed air is an excellent means fluidairedynamics of storing and transmitting energy. It happens to beversatile, flexible, and comparatively safe compared to rest of the methods used to store energy, such as batteries and steam. The batteries are large and have a limited charge life. Steam, on the other hand, is neither cost effective nor easy to use (it gets extremely hot).
Why use compressed air?
One of the primary reasons for making use of compressed air in place of electricity happens to be safety. Into the applications where equipment use to be overloaded, electrical equipment represents a safety risk. Electric shocks or fires can occur and cause property damage or personal injury. Compressed air as well as pneumatic tools mightget used in a variety of conditions, such as on floors or damp places.
Second, compressed air offers more flexibility. It happens to be easier using in isolated locations like mines and construction sites. Air tools are less prone to heating and have variable speed and torque. Look at a jackhammer or impact tool of similar characteristics: it is almost impossible to achieve equal force with electricity, particularly in remote locations.
Tools that run on compressed air are also lighter. They can be made with materials that make them lighter and more ergonomic. Air costs balance out with labor costs, as worker fatigue decreases when using lighter tools.
Finally, there is the cost. The equivalent cost of compressed air can be 7 to 8 times that of electricity. However, equipment designed to use compressed air is less expensive. Its simpler design has fewer parts. Also, air tools are generally more rugged and last longer in production environments.
