Beginning of Air Compressors

The first air compressors created were not machines , like many people may think. In fact they were actually people themselves. Humans used their lungs to blow oxygen onto fires, thus creating the first air compressors. The air compressors we know today are both stronger and more efficient. A healthy pair of human lungs can produce.02 to.08 bar, where one bar equals 14.5 pounds per square inch. Around 3,000 BC metallurgy had made its day view, and humans had turned over a new leaf in air compressors. As metals were melted down, higher temperatures were needed, which lead to a need for more powerful compressors. Hand held bellows were soon created and in the 1,500 BC era foot bellows began to be produced. For 2,000 years bellows driven by foot were the primary choice when it came to compressed air. Soon blast furnaces were developed, which lead to John Smeaton 's design of a water wheel-driven blowing cylinder in 1762. Hand held and foot operated bellows become obsolete, and the ...

How Does an Air Compressor Work?

Air compressors are essential mechanical equipment for homeowners (air conditioners and refrigerators), commercial businesses, jet engines, refining industries, manufacturing and automotive industries. In reality, air compressors have been utilized in industries in more than a century. It is a multi-talented device utilized to supply the compressed air and/or power in a specified space. It is being used in any purpose which requires air in decreased volume or increased force. They are are obtainable in several types, which are produced to meet dissimilar requirements. Each type may vary in chilling method, compression stages, power source and lubrication. The following are three main types of air compressors: Reciprocating (Piston) Air Compressor - uses piston in compressing air and keeping in storage tank. Based on the quantity of compression stages, this type may be single-stage or double-stage. In a single stage, one piston is utilized in compressing air, whereas in the doubl...

Compressed Air Can - Why Do You Need It?

Modern time is the time of electronic appliances and gadgets. In order to assure their long term use, they should not only be used with much care but also be cleaned in the best way to guarantee permanent usage. Compressed air can is a can that is used to remove the dust and dirt which settles down into closed and open areas of any type of machines and devices. The can contains gasses which have been compressed in a way that they turn into liquid. The liquid, then comes out of the can which has a nozzle to permit it passing out, and reaches out even for the hard to reach places to clean the surface of electric appliances. It is an ideal choice to clean your equipment with cans rather than with water. Most of this electric equipment is so sensitive that if cleaned by using water, they can damage the tools and equipment. Most of these cans are available in packages which include several accessories such as refill, which will match the size of the can you are buying, nozzles and dispos...

The Use of Compressed Air in Industry

Although it is perhaps not one of the better known 'tools of the trade', it may come as a surprise to many people, how wide the use of the industrial air compressor is in a wide variety of industries. From the health sector to mining, industrial air compressors are playing an increasingly important role in industry. Whilst this may surprise some, there are a good many reasons why this is the case. Compressed air is easy to store and is usually contained in large tanks, taking up little room in a factory or yard. Compressed air can be especially useful, and important, in an environment that is potentially hazardous; a good example of this is in the mining industry, where the use of electrical machinery could ignite explosive gases, causing injury or even loss of life. As they expel only pure compressed air, there are no toxic fumes or other chemicals to be concerned about either, which is one of the more obvious appeals to the health sector. Before buying an industrial ai...

Understanding Compressed Air Systems

In this day and age, it's difficult to find a manufacturing or construction business that does not use industrial compressors regularly in their daily routine. The key advantage of air compressors is that they can take the potential energy that builds up when a gas such as atmospheric air is placed under pressure and quickly convert it to kinetic energy. That energy can be used to drive small power tools such as impact wrenches or nail guns. Larger compressors are used in manufacturing when a large amount of torque needs to be applied. Most importantly, compressors are quite reliable and don't require extensive maintenance. Basic Components of Compressors compressors are similar to small internal combustion engines since they consist of a piston, a cylinder, and a connecting rod that is attached to a crankshaft. The crankshaft is driven externally, either by an electric or gas motor to rotate the shaft and move the piston up or down. The top of the piston cylinder has a valv...

Compressed Air Safety For Employees

To ensure compressed air safety when personnel are handling compressed air cylinders in the workplace (or in fact at home) all components of compressed air systems should be inspected regularly by qualified and trained employees. Operators carrying out the safety tests should individually take note of: the air receivers, the air distributions lines, the pressure regulation devices, the compressor operation and compressed Air Equipment Maintenance. Compressed air safety should be taken very seriously due to the fact that a compressed gas cylinder accident can be fatal for personnel. While it is perfectly safe to work with if the operator knows what they are doing, it can conversely be very dangerous if handled by someone who has not had the correct training or is not furnished with sufficient information. In order to guard against accidents in the workplace and to ensure a happy and healthy working environment, following are typical safety considerations that should be observed: ...

Compressed Air Energy Storage (CAES)

Compressed Air Energy Storage (CAES) is a way to store energy generated at one time for use at another time. At utility scale, energy generated during periods of low energy demand (off-peak) can be released to meet higher demand (peak load) periods. Compression of air generates a lot of heat. The air is warmer after compression. Decompression requires heat. If no extra heat is added, the air will be much colder after decompression. If the heat generated during compression can be stored and used again during decompression, the efficiency of the storage improves considerably. There are three ways in which a CAES system can deal with the heat. Air storage can be adiabatic , diabatic , or isothermic : Adiabatic storage retains the heat produced by compression and returns it to the air when the air is expanded to generate power. This is a subject of ongoing study, with no utility scale plants as of 2010. Its theoretical efficiency approaches 100% for large and/or rapidly cycled devic...
