Air compressors have numerous applications in industry and are utilized in various fields, including automation and assembly, chemical manufacturing, agriculture and construction. All compressors work by converting power from an additional source, such as an electric motor or diesel engines, into stored energy which is often released in the proper execution of pressurised air. The pressurised air is then used to power tools and machinery.
Choosing the Right Air Compressor
However compressors vary inside their method of operation, air capacity and level of pressure that they may deliver. The right compressor will able to put up enough air and deliver a top enough level of pressure for the duty, but performance should really be balanced against considerations such as cost and durability. Compressed air is measured in cubic feet each minute (CFM), with a top requirement for CFM needing a bigger air capacity and higher horsepower (HP).
Kinds of Industrial Air Compressor
You will find three major forms of industrial air compressor on the basis of the method of operation. These are reciprocating compressors , rotary screw compressors and centrifugal compressors.
Reciprocating compressors are positive displacement compressors , where air is reduced in volume to boost its pressure. Reciprocating contain pumps driven by pistons with a cylinder compressing and displacing the air. You will find two types mini compressor direct drive compressors and belt drive compressors. Belt drive compressors tend to be more durable and in a position to deliver higher pressures. Reciprocating compressors can be purchased in single stage and multi stage. Multi stage compressors deliver higher pressures and tend to be more efficient, meaning lower electricity consumption and lower costs. Reciprocating compressors are often portable and ideal for trades people involved in construction and similar fields.
Rotary screw air compressors also work with a positive displacement process. They use two helical screws meshed together to force air through and compress it. The method of operation is really a smoother process than that of pistons, with less surges and vibration than that sometimes present in reciprocating compressors. They’re durable and simple to maintain. Rotary screw air compressors generally have greater capacities than reciprocating compressors and can deliver higher air pressures. Some types have variable speed drives and therefore airflow and pressure may be closely controlled, and where airflow requirements are variable this may result in significant energy savings. Rotary screw air compressors have various applications, finding use in areas such as construction sites, factories and hospitals.
Centrifugal air compressors work with a different mechanism. They utilize the momentum gained from a spinning disk to transfer and pressurise air. This method is known as dynamic displacement and is really a continuous process, resulting in a steady method of getting pressurised air. They could deliver extremely high pressures. Nevertheless the method also requires higher speeds and higher air capacities than other compressors. The ability and airflow may be controlled by means of inlet guide vanes. Centrifugal compressors have many applications, and are useful for machinery such as pneumatic drills and automotive superchargers and turbochargers, along with for air conditioning and refrigeration. They’re also present in gas turbines, gas pipelines, oil refineries, petrochemical plants and chemical plants.
