Working Principles Of Two-Stage Air Compressors

Understanding the functionalities of air compressors leads us to explore the mechanisms behind 2-stage air compressors. Distinct from single-stage compressors that usually deploy either a piston or rotary screw to intake air and compress it once, 2-stage compressors intensively compress the air twice. This inherently demands the presence of two cylinders to house the pressurized air and a dual methodology for both drawing in and compressing the air.

There are notable differences in the working operations of single-stage and 2-stage compressors. In the single-stage scenario, the air is compressed, consumed, and replaced at a rate that correlates with the capacity of a single piston or screw to draw in air. On the other hand, 2-stage air compressors introduce a second compression phase, enhancing the stored air pressure. This dual-staging is particularly valuable for those in need of higher air pressures, generally exceeding 100 PSI, alongside prompt and consistent air replenishment.

1. Single-Stage Rotary Screw Air Compressor

A single-stage rotary screw compressor operates using a singular rotating helical screw element that compresses air, driven by an electric motor.

This type of compressor can be viewed as a positive displacement motor, delivering a consistent volume for each revolution, known as the swept volume (compressed volume). This volume represents the space that gas will occupy when the rotor returns to its initial stage.

Single-stage rotary screw compressors see widespread application in various areas, including home and industrial air conditioning.

2. Two-Stage Rotary Screw Air Compressor

The Two-Stage Compressor represents an efficient method for delivering compressed air for tools whenever needed.

This compressor type integrates two rotating helical screw elements driven by individual electric motors for each stage. This allows for the provision of a larger volume of compressed air across diverse pressure levels, suiting most pneumatic needs. Additionally, unlike their single-stage counterparts, two-stage air compressors maintain a stable output without significant pressure fluctuations, making them ideal for larger applications.
