Air compressors have many applications in the industrial field and are used in a variety of fields such as automation and assembly, chemical manufacturing, agriculture and construction. All compressors operate by converting the power from an external source, such as an electric motor or diesel engine, into stored energy that can be emitted in the form of compressed air. Pressurized air is used to power tools and machinery.
Choosing The Right Air Compressor
Compressors, however, differ in how they operate, the capacity of the air, and the pressure levels they can deliver. Not only can adequate compressors accommodate sufficient air, but they can also provide sufficient pressure for the job, but they must balance performance, cost, and durability. Compressed air is measured in cubic feet per minute (CFM), and there is a high requirement for CFMs that require greater air capacity and higher horsepower (HP).
Types of Industrial Air Compressors
There are three main types of industrial air compressors, depending on how they work. These are reciprocating compressors, rotary screw compressors and centrifugal compressors.
Reciprocation
A reciprocating compressor is a saturated compressor that increases the pressure by reducing the volume of air. The reciprocating motion includes a pump driven by the piston, which compresses and moves the air. There are two types of direct drive compressors and belt driven compressors. Belt driven compressors are durable and can deliver high pressures. Reciprocating compressors are available in single and multi-stage. Multistage compressors provide higher pressure and operate more efficiently, reducing power consumption and lowering costs. Reciprocating compressors are portable and suitable for people engaged in construction and similar fields.
Rotary Screw
Rotary screw air compressors also operate with a positive displacement process. Use two helical screws to forcibly push and compress air. The operating method is a smoother process than a piston with less surge and vibration than is often found in reciprocating compressors. They are durable and easy to maintain. Rotary screw air compressors generally have greater capacity than reciprocating compressors and can provide high air pressures. Some types have variable speed drives that allow for close control of airflow and pressure, and considerable energy savings when the airflow requirements are variable. Rotary screw air compressors have a variety of applications that are used in fields such as construction sites, factories and hospitals.
Centrifugal
Centrifugal compressors work with different mechanisms. They use the momentum obtained from the rotating disk to transfer and compress air. This process is known as dynamic displacement and because it is a continuous process, pressurized air is supplied reliably. They can deliver very high pressures. However, this method requires higher speed and higher air capacity than other compressors. Capacity and airflow can be controlled via inlet guide vanes. Centrifugal compressors have many applications and are used in air conditioners and freezers as well as pneumatic drills and machinery such as car superchargers and turbochargers. It is also found in gas turbines, gas pipelines, refineries, petrochemical plants and chemical plants.
