Air Compressors and How They Function
Air compressors are necessary for different industries as they are used in automation and assembly, agriculture and construction and also in chemical manufacturing. The task of the air compressors is to convert the power from an electric motor or a diesel engine into stored energy form which is later released in the form of pressurized 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. 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.
Based on their method of operation, there are three types of industrial compressors that one can purchase 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. 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 not only effective but also portable and suits the construction traders.
The second type of compressors is the rotary screw compressors which also function by positive displacement process. The rotary screw compressors operate using helical screws and are smoother than the pistons thus less surges and vibration than the case of reciprocating compressors. They are also durable and also easy to maintain while their capacity is also larger than that of the reciprocating compressors. The rotary screw compressors also allow one to control the airflow as they come with variable speeds and are widely used in hospitals, construction sites and factories.
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.
