Air compressors are mechanical devices which increase the pressure of the oil or gas by reducing its mass. An air compressor in simple terms is a special type of internal combustion engine that uses a pressurized tank to mix and store compressed air in a closed tank. This pressurized air is the product of gas compression, with a small amount of air going into the tank at high pressure and a much larger amount of air going out at low pressure.
Compressors are divided into two main categories based on their mechanism and the way in which they work. The two major types of air compressors are the displacement in compression and the reciprocating compression types. The displacement in compression air compressors works by allowing more gas to be compressed and compressing it rapidly (DIP) resulting in a small increase in pressure. On the other hand, the reciprocating compression air compressors work by letting the same amount of gas to pass through the nozzle in order to reduce the overall pressure by compressing it slowly (RCC). Reciprocating compressors are generally used for low pressure applications. Visit Swift Equipment website to see the available used portable air compressors for sale now.
These two compressor types are generally categorized as gas and oil-free compressors. A gas-free compressor runs through an electric motor instead of an impeller. As you may know, electric motors tend to be more durable than impellers because they do not need any lubrication and they are less likely to overheat. Because gas-free compressors run through electric motors, you can use them even in areas where there is not power or electricity. There are even some gas compressors which have been converted to run purely on the force of atmospheric air pressure. They use the same principles of the electric motor, only they run on a different frequency.
Air compressors can also be classified according to the pressure they can handle. The flow capacity of these devices will be based on this. A tankless compression air compressor, for instance, has no liquid to slow down during compression and so it can handle very high pressure. There are exceptions though, such as the 12-volt models, which can handle up to three times as much pressure as their conventional counterparts.
The third type is classified according to its portability. You have to consider whether you want to use the device for long-term portable air compressors, or if you just need to use them occasionally. If you plan to use them occasionally then you should get a smaller compressor to start with. On the other hand, if you are going to carry them around then it would be more advisable to get a bigger and more powerful compressor that could be powered by your vehicle's battery or, in the case of jackhammers, even with a solar panel. You can even find some portable air compressors that can run on diesel. Discover the most affordable portable air compressors and caterpillar generators for sale here.
Finally, you also need to know how air positive displacement works. Air positive-displacement compressors work by creating a chamber whose volume is lower than the surrounding air pressure. The air pushes on this chamber, which expands causing a pressurized gas to be released. Air positive-displacement compressors work in a similar way to a normal vented tire pump by creating a low pressure area in the cylinder, which is higher than the ambient pressure.
