55kW 75HP Two Stage Energy-saving Stationary Oil-injected Screw Air Compressor Compressor tornillo

Two-stage compression energy saving principle:
Oil-injected screw air compressors use two-stage compression to improve the energy efficiency of the compressor. The two-stage compression screw main engine adopts two-stage segmented compression, namely the first-stage compression and the second-stage compression. 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 power consumption.
The double-stage compression main engine reduces the compression ratio of each stage, reduces the internal leakage, improves the volumetric efficiency, reduces the bearing load, and improves the life of the main engine.
●Double-stage compression replaces single-stage compression, the exhaust volume is increased by nearly 15%, and the energy saving effect of up to 15% can be achieved.
The compression ratio of each stage is small, the compression ratio of each stage reduces the bearing load, the leakage is smaller, the volumetric efficiency is high, the vibration is low, and the noise is low.
●Under the same power, the two heads bear the load, the bearing is less stressed and the service life is longer.
