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 external source, such being an electric motor or diesel engines, into stored energy which may be released in the form of pressurised air. The pressurised air is then used to power tools and machinery.
Choosing the Right Air Compressor
However compressors vary within their method of operation, air capacity and degree of pressure that they’ll deliver. The proper compressor will able to keep enough air and deliver a high enough degree of pressure for the task, but performance should be balanced against considerations such as cost and durability compressor for mini fridge Compressed air is measured in cubic feet each minute (CFM), with a high requirement for CFM needing a bigger air capacity and higher horsepower (HP).
Types of Industrial Air Compressor
You will find three major forms of industrial air compressor on the basis of the method of operation. They are reciprocating compressors , rotary screw compressors and centrifugal compressors.
Reciprocating compressors are positive displacement compressors , where air is reduced in volume to increase its pressure. Reciprocating contain pumps driven by pistons with a cylinder compressing and displacing the air. You will find two types, direct drive compressors and belt drive compressors. Belt drive compressors are 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 are more efficient, meaning lower electricity consumption and lower costs. Reciprocating compressors are often portable and suitable for trades people involved with construction and similar fields.
Rotary screw air compressors also work by way of a positive displacement process. They choose two helical screws meshed together to force air through and compress it. The method of operation is a smoother process than that of pistons, with less surges and vibration than that sometimes found in reciprocating compressors. They’re durable and an easy task 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 can be closely controlled, and where airflow requirements are variable this can lead to 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 by way of a different mechanism. They use the momentum gained from a revolving disk to transfer and pressurise air. This method is recognized as dynamic displacement and is a continuous process, causing a steady method of getting pressurised air. They could deliver very high pressures. Though the method also requires higher speeds and higher air capacities than other compressors. The capability and airflow can be controlled through inlet guide vanes. Centrifugal compressors have many applications, and are employed for machinery such as pneumatic drills and automotive superchargers and turbochargers, in addition to for air conditioning and refrigeration. They’re also found in gas turbines, gas pipelines, oil refineries, petrochemical plants and chemical plants.
