the current situation

As the development of science and technology, the rotor material nowadays of screw compressor and centrifugal compressor had very great progress and change, the author has done test of a few research to this, this article discusses just a little slightly. Material of rotor of 1 centrifugal compressor is centrifugal compressor rotor is multi-purpose stainless steel is made, but the centrifugal empty press on hydrogenous batteries car however somebody uses aluminium alloy to make rotor, and make rotor as generally however as this adjacent car supercharger with stainless steel. Go up as a result of hydrogenous batteries car from
