Air Compressors



Air compressors are mechanical devices which increase the pressure of an atmosphere by reducing its volume in the same way that a large cylinder reduces the volume of an oil bottle. An air compressor is a particular kind of industrial air compressor. It works on the principal of reciprocating compression, in which an air pump compresses a gas (oxygen or nitrogen) in a container, and forces it into another container in return. The final, released gas, in a cylinder, acts in much the same way as a compressed solid liquid, for example, when a car engine has to push out the same amount of air that it takes in, whether that's a liter or a gallon.

There are two basic types of compressors: single-stage and reciprocating air compressors. A single-stage air compressor runs only one cycle; its compressor stroke is generally limited to the intake of one gaseous (oxygen or nitrogen) at a time. It uses a long thin metal tube called a statuary, which consists of several concentric rings or cylinders. As the compressed air flows through the statuary, it expands its interior walls, thus allowing a second, smaller ring, or cylinder, inside the statuary, to open. This second, smaller ring then compresses the gas inside the single-stage cylinder. Click for more info about diesel powered air compressor .


This process, repeated a number of times, allows the compressed gas to reach its maximum pressure, before the valve shuts off and on again.
Reciprocating air compressor types work in a similar fashion to single-stage compressors, but it begins with the intake of a lighter fuel, like propane. The air is blown by the pilot to the tip of the reciprocating piston, where it is compressed yet again. The third stage, which contains the oil for lubrication, draws all the air pressure out of the piston. In some of today's models, the O-rings, or balls, are replaced by pressure relief devices that eliminate the need for oil. The result is an air compressor that operate more rapidly than any other available, and it produces much less pressure than the other two.



Pulse Dispensing - these units use a variable-speed electric motor to rotate the discs inside a chamber, which expands as the motor rotates. Because of this, the inner pressure builds continuously, even when the motor is turned off. These types of compressors must have a very high efficiency, or else the pump will overheat. They tend to be the most energy-efficient compressors, but they also cost the most to run.


Rotary screw vane - these pumps utilize an intermediate pumping action between the screw and vane flow. A screw vane refers to the innermost part of the rotor. These types of compressors are usually found in sewage treatment plants or sewage treatment facilities, and are often used to power vacuum systems. They can pump a large volume of air, although their performance does not match that of other rotary compressors. As their name implies, their operation is similar to that of a screw jack.


Rotary displayed pump - these pumps are used in applications that require high pressure pumping. They use a fixed displacement pump, which is rotated by a fixed-length screw. In these pumps, the screw is typically located at a low-profile level, allowing for a high volume pump to be installed. The assembly simply moves up or down to change the pressure. They are also often used in high-volume water pump applications.
