Buying Single-Stage and Two-Stage Reciprocating Compressors

Reciprocating compressors with industrial applications come generally in two types. One is a single-stage reciprocating compressor and the other two-stage reciprocating compressor. Going to but this single-stage or dual-stage reciprocating compressor, the first question that might arise in your mind, would be that what exactly the differences between these two variants are. Let’s put some light on this fact and analyze both types with their implications.

Just like their names suggest, the exact difference between these two types of compressors is the number of stages, air goes through the process of compression before reaching out to the final cooling phase. With this application, the air is compressed once in a single-stage reciprocating compressor while, in a two-stage reciprocating compressor, the air is compressed in two stages, or phases to double the entire pressure mechanism and cool more vigilantly.

To understand this scenario better, we need to thoroughly understand or dig out what exactly happens in every stage. Let’s do some research and analyze what happens in both stages of reciprocating compressors.

Single-stage

In a single-stage air compressor, the air comes up with a sucking mechanism into the compression cylinder with the help of a filter that works through the impacts of two inlet valves and the movement of pistons. After the induction of the necessary amount of air drawn to the cylinder, the inlet valves close and the crankshaft starts to rotate. This movement pushes the piston upward to compresses the air and then pushing the air to the exit valves. This pressurized air is further discharged into the storage tank to use when needed or to go on further for the cooling phase.

In contrast to the procedure described above, in a two-stage air compressor, the process of sucking and compressing might be similar to a single-stage compressor, but the air goes through the second phase of compression or double compression with new pressure application and further cooling phase. This will differentiate the process in a way that compressed air isn’t stored in a storage tank yet. The compressed air is employed to another compression with a new pressure by a small piston in the second cylinder. Through this process, the air is double pressurized and comes out with double energy and then stored in a tank for further cooling processes.

You might think which stage process is better out of these two. The single-stage reciprocating compressor is suitable for simple and manhandles tasks with low-pressure requirements. Therefore, this may be the best choice for auto shops for trimming, framing, nailing purposes, or similar small tasks.
Whereas, a two-stage compressor is made to deliver more pressure or intensity to make it suitable for factories and construction purposes, requiring more and continuous air supply or air pressure.

This may cost more than a single-stage compressor and therefore, may not be suitable for local or personal use.
