1. Compared with single-stage compression, the trend of two-stage compression is close to the most energy-saving isothermal compression. In principle, two-stage compression is more energy-saving than single-stage compression.
The two-stage compression air end is adopted, that is, two groups of robust screw rotors with different sizes are adopted to realize reasonable pressure distribution and reduce the compression ratio of each compression. Low compression ratio has two special advantages: one is to reduce internal leakage and improve volumetric efficiency; The other is to greatly reduce the load of the bearing, improve the service life of the bearing and prolong the service life of the main engine.
2. High end configuration and system optimization
The key points are also reflected in the local design and details of the product, as well as the high-end configuration and optimization of the system, which is 5 ~ 8% more efficient than other brand products. The efficient air end and the innovative technologies inherent in the robust series, such as air inlet regulation design, smooth cooling design, oil-gas separation technology, efficient motor, intelligent control and so on, will be widely used key customers bring real energy-saving benefits.
