Air Compressors and How They Function

Air compressors are essential as their services are applied in many industries such as agriculture, construction, chemical manufacturing and the automation and assembly industries. The air compressors function by converting power from an external source, primary an electric motor and diesel engines where they convert the electric power to the stored energy released in the form of pressurized air. Pressurized air from the compressor is used to power other machinery and equipment. When selecting the compressor to purchase, there is the need to be keen as they are costly equipment and any mistake will cost the company huge amount of finances. Various kinds of air compressors are available, and thus one’s choice depends on factors such as the capacity of air, the operation methods of the compressor and also their pressure levels. When one is purchasing an air compressor, they also need to determine the cost of a given air compressor, the durability and also the ability of the compressor to balance the capacity of the air they hold and the pressure levels of the air that they release.

Three main types of compressors, based on the operation methods, are available in the market. The first kind of compressor is the reciprocating compressors which are categorized as positive displacement compressors. They function by reducing the volume of the air thus increasing the pressure as they have pumps driven using pistons which are attached to the cylinders that compress and displace the air. One also, chooses between the direct drive and the belt drive kinds of reciprocating air compressors but it is advisable to purchase the belt drive compressors as they are durable and also effective. The reciprocating compressors are portable and thus suits traders in construction while they are also efficient.

The second type of compressors is the rotary screw compressors which also function by positive displacement process. In their operation, the rotary screw compressors are smoother in comparison with the reciprocating compressors, as they use helical screws and not pistons and thus have less surges and vibration. One can also decide to purchase the rotary screw compressors as they are easier to maintain and are also durable and in comparison with the reciprocating compressors they have larger air capacity. Some have variable speeds meaning that one controls the airflow and they are used in construction sites, factories and hospitals.

The third kind if the air compressors that one can buy is the centrifugal compressors which depend on the momentum from a rotating disk to transfer and pressurize air. They are capable of delivering extremely high pressures which are controlled by way of inlet guide vanes. They are used in refrigerators, automotive and air conditioners.
