A BRIEF HISTORY OF AIR COMPRESSORS

Air compressors have been around due to literally thousands of years. whereas granted the devices the ancients practiced for compacting air take little resemblance to the modern air compressor. However, the basic principle is the same and adrift the primitive air compressors, civilization would not take it evolved as fast it has. One of the primary uses for compressed atmosphere was to increase the combustion in the furnace. its operator of a forge would use a bellows to explosion compressed air into the furnace to stoke increase the heat. This allowed ancient man to produce stronger and higher quality metals for tools and weapons. Most people today would not equate a bellows as an air compressor, but that is exactly what it is. the blacksmith would pull apart the handles on its bellows besides a check valve would allow fresh air to enterprise into the accordion like chamber. Then using muscles as the power source, its blacksmith would squeeze the handles together and the compressed air would shoot out the fitting on the end. Using this process it became possible to occasion a fire hot enough to smelt ores of copper, tin, lead and iron. Bellows are inactive used today guidance a variety of applications. The organ at your inborn church is probable powered by a bellows that is practically identical to one the thousand years ago. They planed pop up in medical applications such as breathing machines in operation rooms.

It wasn't until later in history that it became possible to compress air running mechanical methods. In the past, only human and animal power was possible to power crude atmosphere compressors and this unduly limited its utility of these primitive devices. With the industrial revolution, the automatic air compressor was born. Engines running from force power became the first method to power an air compressor. One of the first uses of a momentum powered air compressor was in underwater diving equipment. This opened up whole new methods for under water exploration and even underwater construction. The compressed air could be pumped down to a diver and allow broad stays below surface. Compressed air was also much safer to use thanks to a power source for anterior pneumatic tools and drills. For example, original force drills were powered through steam. However, hot steam is far more hazardous than compressed air. A ruptured sock line can kill or seriously injure a worker instant compressed atmosphere is relatively benign. impulse powered rock drills eventually gave way to drills powered through air compressors.

As the internal combustion engine gained popularity, they began to be used as a power source for air compressors. Gasoline engines are today commonly practiced in piston type air compressors. This would be a common air compressor you would find in your garage or on the back of a service support. The gasoline engine drives a crankshaft besides piston. as the piston moves into;nation the downstroke postion, air flows into the cylinder on the low pressure end. When the upstroke begins, air moves into;nation the high pressure. This action produces compressed air. In bigger industrial applications, a rotary morale air compressor is used. Rotary air compressors produce compressed air through branch the vaned rotor inside of a long enclosed chamber. As the engine spins the rotor, atmosphere is sucked inside the chamber. the air is then forced down its vanes into smaller and smaller areas. This action compresses the air and army it out the other solve. Rotary vane air compressors work very well in industrial applications because they are capable of producing large amounts of compressed air for extended periods of time.See Others
