Welcome Suzhou Hengchaowin Technology Co., Ltd!
The working principle of the two-stage double screw air screw air compressor:
The double compression screw host adopts two-stage sub-compression. After the first-stage compression, the oil and gas can be fully mixed between the stages, reducing the suction temperature of the second-stage compression, thereby reducing power consumption.
1. After the first-stage compression, the oil and gas can be fully mixed between the stages to reduce the suction temperature of the second-stage compression, thereby reducing the power
2. consumption.
3. Two-stage compression replaces single-stage compression, and the displacement increases by nearly 15%, which can achieve an energy saving effect of up to 15%.
4. The compression ratio of each stage of compression reduces bearing loads.
5. The compression ratio of each stage is small, the leakage is smaller, the volumetric efficiency is high; the vibration and noise are low.
6. Under the same power, the two heads bear the load, the bearing is less stressed and the service life is longer.
To put it simply, using a smaller motor to achieve a larger displacement!
the energy saving effect is 35-40% higher than that of ordinary screw air compressors, and 15% higher than that of ordinary variable frequency air compressors.
