Air Compressors

-

Air compressors are mechanic devices that take in air and then compress and store it in a compressed form (meaning, it occupies less space than in its normal state). Air compressors are equipped with a tank that holds the compressed air inside. The tank is able to withstand all the pressure that the air applies inside it, but there are always signs that warn the user that damaging the tank can result in an accident.

One major difference between the various types of air compressors is that some of them are oil-lubricated while some others are not. Those that are not oil lubricated are also called oil-free compressors. Oil-free compressors boast the advantage that they don’t need oil in order to operate, while oil-lubricated compressors do. Additionally, oil-lubricated compressors need to have their oil changed after certain periods of operation.

Another difference that can be seen among air compressors is that some of them are stationary (meaning they are static or unmovable), while some others are designed from scratch to be portable. Common air compressors are not used for industrial purposes, and they occupy the same volume as a medium-sized table. This type of compressor usually comes with built-in wheels in order to be more portable. However, air compressors aimed at industrial use can occupy areas larger than one, two, or even more rooms. These compressors are not intended to be moved more than a few times during their lifetime. Moving these compressors requires money as well as good planning.

Air compressors can be found in homes, small businesses, service stations, or in large industries. Their usage ranges from dust cleaning to heavy industry usage (inside machinery) and gas turbines. Air compressors play an essential role in the correct operation of many devices and procedures.

Air compressors work - Compression process

To understand how to save the energy in compressed air system , it is useful to start with theory background of how the air compressors work and how the energy is consumed. As we know from Thermodynamic principle that the compressor work is, where: rev = reversible in = input Our objective is to minimize the air compressor work that means to approach the reversible process i.e. minimize the friction, and turbulence Practical way to do this is to make v (specific volume) small by maintaining T (temperature) at low temperature during compression because v a T. In other words, to reduce the work input to a compressor, air should be cooled as it is compressed. Effect of Cooling Isentropic process: No cooling during compression Polytropic process: Involve some cooling Isothermal process: Involve maximum cooling Which process yields the minimum required compressor work? Let's consider the following equations of each process. Assumptions: All three processes are executed between the same

The electric motor is usually the prime mover of the air compressors. Therefore, to save the energy of compressed air system is to save the energy consumption of the electric motor. Energy saving of the electric motor can be written as shown in the following formula Thus, Cost savings = Energy savings x Unit cost of energy

Tips to Reduce Compressed Air System Pressure Drops

-
Ask a Question: What causes pressure drops in my compressed air system and how can I reduce them? Answer: Pressure drop can become a compressed air system problem that steals production time and money. What causes pressure drops? Any type of obstruction, restriction, or roughness in the system will cause resistance to air flow and cause pressure drop. In the distribution system, the highest pressure drops usually are found at the points-of-use, including undersized or leaking hoses, tubes, disconnects, filters, regulators and lubricators (FRLs). On the supply side of the system, air/lubricant separators, aftercoolers, moisture separators, dryers and filters can be the main items causing significant pressure drops. The maximum pressure drop from the supply side to the points-of-use will occur when the compressed air flow rate and temperature are highest. Your Compressed Air System components should be selected based upon these conditions and the manufacturer of each component should b
