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 ...

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...

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...

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...

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...

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) 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...

An air compression is a means by which one type of energy is converted to another. During this conversion certain losses occur because of the rise in temperature of the air as it compressed. In general practice, the air is stored in a receiver and heat is lost both in the receiver and pipe lines running to equipment. Since the rise in temperature of the air is a direct loss of energy. We want to keep it down to a minimum. The ideal method is to compress air isothermally but this is impossible in practice owing to lack of time necessary to affect transfer. Water jackets and inter-cooling can be used to keep the temperature down. These have the effect of reducing the compression index (n) to something less than 1.4. When air is compressed to a pressure to exceeding about 4 bar it is usual to compress it in stages, with intercooling between each stage. This considerably reduces the total amount of work required on the air. For two stages compressing, the air is compressed in the first...

Air is not a perfect gas but for practical purpose the laws relative to perfect gases may be applied to it. Boyle’s law states that: The absolute pressure of a gas varies inversely as the volume, provided the temperature remains constant. p V = a constant where: p = pressure in bar, V = volume in m 3 . Charles’ law states that the volume of a gas under constant pressure, or the pressure of a gas under constant volume, varies as the absolute temperature. Therefore V varies as T, and p varies as T where T is the absolute temperature. If the two laws are combined, we get: p V / T = constant The constant is usually denoted by R and therefore: p V = R T It can be shown that the value of the constant R applicable to air is 287.0 J/(kg K). The relation between the pressure and volume of air during its expansion and compression may be represented by: p V n = R T where ‘n’ has value which depends on the addition or subtraction of heat during the process . When the te...

Approximately 10 % of all electrical power used in industry comes from compressed air. This is proof of its widespread usage but it is also evidence of the potentially large saving in costs which could be achieved if the energy management opportunities are put into practice. Normally, the purpose of compressed air systems in the industrial sectors is to deliver the necessary volume of air at the required pressure and temperature to the correct places. Compressed air is used for operating pneumatic equipments, cleaning purposes, and other general services. This is accomplished by a distribution system consisting of pipes, valves and fittings. The Compressed Air pipe work is arranged in the form of ring mains with interconnections to points of end-users. Careful evaluation of existing compressed air systems can ensure against improper operation, and poor energy utilization. Alert design, operations, and maintenance personnel, with an awareness of energy management, can achieve signif...

Let's continue from [ Compressed Air System Energy-Reduction Case Study (Part 1) ] Compressed Air Energy-Reduction Strategy Project Goals and Implementation Following the IAC assessment, FUJIFILM’s maintenance team formulated project goals and an implementation plan that centered on the utilization of existing facility infrastructure and equipment. The team’s implementation strategy was divided into three phases and focused on increasing the system’s storage capacity to handle production peaks and valleys; lowering air compressor operating pressure; repairing system leaks; and ultimately, operating the facility with one compressor. The team’s strategy was also aided by the company’s closure of its Orange Park, Florida, operations. This facility housed a 75 horsepower (HP) air compressor, a dryer, and a receiver, which the Dayton facility incorporated into its efforts. Project success, then, depended on the accomplishment of four specific goals: To increase system redundanc...

FUJIFILM Hunt Chemicals U.S.A. Achieves Compressed Air System Energy-Reduction Goals with a Three-Phased Strategy. In an attempt to eliminate equipment failures and downtime issues associated with the plant’s compressed air system, FUJIFILM Hunt Chemicals U.S.A.’s in-house maintenance team worked with a team of faculty and students from the Tennessee Technology University Industrial Assessment Center (IAC) to conduct an assessment at its Dayton, Tennessee, facility to identify opportunities for improvement. Following the assessment, the team formulated an implementation plan that would increase the system’s reliability, reduce system maintenance costs, reduce the facility’s overall energy use, and eliminate the use of nitrogen when compressed air systems are down. The Energy Situation The Dayton facility was experiencing excessive downtime due to chronic air compressor failures and significant inefficiencies throughout its compressed air system. In 2007 alone, system operating costs...

Stabilizing system pressure is an important way to lower energy costs and maintain reliable production and product quality. The need to stabilize system pressure should be guided by the compressed air demand patterns and the minimum acceptable pressure level required for reliable production. High-volume intermittent air demand events can cause air pressure to fluctuate, which is often misinterpreted as insufficient pressure. In some cases, improperly set compressor controls will cause another compressor to start, but because of the time required for the new compressor to ramp up, there will be a shortfall of air supply to the system. Such a delay can cause the system pressure to decay, resulting in lost production. Three methods can be used to stabilize system pressure: adequate primary and secondary storage, Pressure/Flow Controllers (P/FCs), and dedicated compressors. Primary and Secondary Storage One or more compressed air applications having large, intermittent air demands can...

Removing condensate is important for maintaining the appropriate air quality level required by end uses. However, significant compressed air (and energy) losses can occur if condensate removal is done improperly. Excess compressed air loss during condensate removal can occur due to several factors. Following shows several condensate removal methods and the characteristics of each method. Manual operation: Operators manually open valves to discharge condensate. Depends on people opening valves at the appropriate time for the necessary amount of time. Often leads to excess loss because air escapes when the valves are left open to drain the condensate. Level-operated mechanical float traps: Use a float connected by linkage to a drain valve that opens when an upper setting is reached and closes when the drain is emptied. Require considerable maintenance. Are prone to blockage from sediment in condensate. Are prone to getting stuck in open position (leak excess air) and in the ...

A brewery neglected to perform routine maintenance on its compressed air system for years. As a result, two of its centrifugal compressors, whose impellers had been rubbing against their shrouds, were unable to deliver the volume of air they were rated for and one of those units had burned up several motors during its lifetime. In addition, plant personnel did not inspect the system’s condensate traps regularly. These traps were of a type that clogged easily, which prevented the removal of moisture and affected product quality. Also, the condensate drains were set to operate under the highest humidity conditions, so they would actuate frequently, which increased the system’s air demand. As a result, energy use was excessively high, equipment repair and replacement costs were incurred unnecessarily, and product quality suffered. All of this could have been avoided through regular maintenance. Like all electro-mechanical equipment, industrial compressed air systems require periodic mai...

"Maintaining the proper air quality level is essential for keeping compressed air energy costs down and to ensure reliable production." Poor air quality can have a negative effect on production equipment and can increase energy consumption and maintenance needs. The quality of air produced should be guided by the quality required by the end-use equipment. The air quality level is a function of the levels of particulate, moisture, and lubricant contaminants that the end uses can tolerate. Such air quality levels should be determined before deciding whether the air needs additional treatment. Compressed air should be treated appropriately but not more than is required for the end-use application. The higher the quality, the more the air usually costs to produce (in terms of initial capital investment in equipment, energy consumption and maintenance). Once the true end-use air quality requirements have been determined, the proper air treatment equipment can be configured. Se...

Compressed air is one of the most important utility requirements of many industrial manufacturing plants because it directly serves processes and applications such as pneumatic tools, pneumatic controls, compressed air operated cylinders for machine actuation, product cleansing and blow-off applications. Ensuring an appropriate, stable pressure level at the end-use applications is critical to the performance of any industrial compressed air system. End uses that are engineered for maximum efficiency can help provide the consistent supply of compressed air that ensures reliable production. To ensure the efficiency of compressed air end-use applications, a number of steps should be taken: Review the pressure level requirements of the end-use applications. Those pressure level requirements should determine the system pressure level. Because there is often a substantial difference in air consumption and pressure levels required by similar tools available from different manufacturers, ...

Compressed air generation is one of the most expensive utilities in an industrial facility. When used wisely, compressed air can provide a safe and reliable source of power to key industrial processes. Users should always consider other cost-effective forms of power to accomplish the required tasks and eliminate unproductive demands. Inappropriate uses of compressed air include any application that can be done more effectively or more efficiently by a method other than compressed air. The table below provides some uses of compressed air that may be inappropriate and suggests alternative ways to perform these tasks. Potentially Inappropriate Uses could be replaced by following suggested alternatives: Clean-up, Drying, Process cooling: Low-pressure blowers, electric fans, brooms, nozzles Sparging: Low-pressure blowers and mixers Aspirating, Atomizing: Low-pressure blowers Padding: Low to medium-pressure blowers Vacuum generator: Dedicated vacuum pump or central vacuum system Pers...
