What is the difference between a single-stage and two stage screw compressor?

Two stage screw air compressors |
Single-stagescrew air compressors |
|
Compression ratio: |
Two-stage screw air compressors consist of two pairs of yin and yang rotors. After the gas is compressed in the first stage, it enters the second stage for compression, with a high compression ratio. |
Single-stage screw air compressors use one-step compression to achieve air compression, with a relatively low compression ratio, suitable for low-pressure gas loads. |
|
Compression efficiency: |
Two-stage screw compressors compress air in two steps - first compress to medium pressure, and then compress to higher pressure after cooling in the intercooler. This brings higher efficiency and better performance for applications that require higher pressure. |
Single-stage screw compressors compress air in one step to reach medium pressure, and the efficiency is low at high pressure. |
|
Gas output: |
Due to the design features and high efficiency of two-stage screw air compressors, their gas output is improved compared to single-stage screw air compressors. |
Single-stage screw air compressor has low gas output |
In summary, two-stage screw air compressors provide higher gas output and better energy efficiency through their high compression ratio and two-stage compression design, and are suitable for applications that require high pressure and large amounts of gas. Single-stage screw air compressors are suitable for small and medium-sized equipment or occasions where gas demand is not particularly high due to their simplicity and low cost.
How two stage screw air compressor Works？
First stage compression:
Natural air first enters the first stage compression through the air filter, mixes with a small amount of lubricating oil in the compression chamber, and compresses the mixed gas to the interstage pressure. After the first stage, the compressed air passes through the intercooler. The intercooler cools the air, which helps to reduce the load of the second stage and improves the overall efficiency by reducing the air temperature.
Second stage compression:
The compressed gas after cooling enters the second stage rotor for secondary compression and is compressed to the final exhaust pressure. The second stage increases the gas pressure to the required level, which is usually higher than the pressure of a single-stage compressor.
Discharge:
Finally, the compressor is discharged through the exhaust flange to complete the entire compression process. Ready for use in various applications.
Advantages of olymtech two stage screw air compressors
1. Super energy saving 2 stage air end, which is higher efficiency.
2. Permanent Magnet VSD motor, with more than 95% high efficiency.
3. Direct driven, no transmission energy loss.
4. Inovance inverter&upgrade cooling system, ensure high efficiency and long service life.
5. Colorful touch screen, user friendly design.
6. Using the centrifulgal fan, lower noise and have a much larger volume than the axial flow fan.
7. Strong cylinder intake value, much stable and have a longer service life.
8. Separated cold/hot area to ensure the air compressors can run in the high temperature environment.
9. Thick sound proofing enclosure to make sure the low noise operation.
