How to Select the Right Air Compressor
Air compressors are necessary for different industries as they are used in automation and assembly, agriculture and construction and also in chemical manufacturing. 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 is used in the industries to power machinery and equipment. When in the market seeking for an air compressor there is the need to pay attention to select the best compressor as a mistake will lead to financial loss on the part of the company. Different types of compressors are available which vary regarding the level of pressure of the air they are delivering, their operation methods and also the capacity of air that a given compressor can deliver. One thus needs to consider the duration as well as the cost of buying the compressor when they are buying one as much as they need to purchase a compressor that will balance capacity of the air they can hold and the level of pressure that they deliver.
Based on their method of operation, there are three types of industrial compressors that one can purchase in the market. One kind of the compressors is the reciprocating compressors which work as positive displacement compressors. The reciprocating compressors have pumps which also have pistons and cylinders that are attached which serves to press the air reducing the volume of the air and thus resulting in the high pressures of the air being displaced from the compressor. 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. Due to their portability and their effectiveness the reciprocating compressors are recommendable for the building traders.
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. 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. The rotary screw compressors are used in hospitals, construction sites and factories as they also have variable speeds allowing one to control the airflow.
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. For companies in need of compressors that can provide extremely high pressures which is controllable, they can purchase this kind. Some of the applications of the centrifugal compressors include in automotive, air conditioners and refrigerators.
