Energy-Saving Two-stage Compression Screw Air Compressors with Low Speed
Applying the perfect match of Rare-earth permanent magnetic motor, inverter and coupling transmission, the double-stage end can be driven with highest efficient. The working life of the double stage is much longer than regular model due to the lower RPM, besides the power saving is more obvious by above 20%. With two screw rotors of different sizes, the reasonable pressure distribution can be realized to reduce the compression ratio of each compression. The low compression ratio reduces the internal leakage, increasing the volumetric efficiency, and greatly reduces the bearing load, extending the service life of main machine.
