50HP Industrial electric air compressor PM VSD two stage screw air compressor
Product Description
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.
