The Various Types of Air Compressors
In different sectors one of the most used equipment is the air compressors as they are used in automation and assembly, agriculture, construction and the chemical manufacturing industries. The primary task of an air compressor is to convert the power from an external source mainly diesel engines and electric motors to stored energy which is released in the form of pressured air. The pressurized air is then transferred where it is used to power tools and machinery. It is important that one pays attention when they are selecting a compressor, as any mistake will lead to financial losses to the company. The compressors that are available in the market vary in terms of their operation methods, level of pressure that they are capable of delivering and their air capacity. 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. Reciprocating compressors are the first kind of air compressors where they function as positive displacement compressors. In positive displacement compressors, the volume of the air is reduced using pumps which are driven using pistons which are attached to cylinders that compress and also displace the air where the released of has high pressure as a result of the reduced volume. There are two kinds of the reciprocating compressors as one can choose between the direct drive compressors and the belt drive compressors but most buyers prefer purchasing the belt drive compressors as they are durable and also have high output. The reciprocating compressors are portable and thus suits traders in construction while they are also efficient.
The second kind of air compressors, which also function as positive displacement compressors, are the rotary screw air compressors. The rotary screw compressors are reliant on helical screws rather than the pistons and thus have less surges and vibration in comparison to the reciprocating compressors. They are also durable and also easy to maintain while their capacity is also larger than that of the reciprocating compressors. Some have variable speeds meaning that one controls the airflow and they are used in construction sites, factories and hospitals.
One can also purchase the centrifugal compressors which have a rotating disc which provides the momentum to move and also pressurize air. For companies in need of compressors that can provide extremely high pressures which is controllable, they can purchase this kind. They are used in refrigerators, automotive and air conditioners.
