Centrifugal compressor blade shape has a dollar wheel, binary wheel and ternary wheel. One element wheel has no twist, simple manufacturing, but the blade resistance loss is large, low efficiency, has been eliminated by the current centrifugal compressor used. Binary vanes are non-spatially twisted. Ternary blade surface twist for space twist, ternary surface is also divided into two kinds, space surface of the bus for straight line straight surface impeller and space surface of the bus is not straight free surface impeller. Ternary impellers are difficult to manufacture, but with low flow resistance and high efficiency, they are widely used in modern centrifugal compressors.
Dear Air Separation small air separation unit and large air separation plant have advanced technology and strong research and development capabilities that are in line with international standards, thanks to the long-term cooperation with the Chinese Academy of Sciences and the Japanese Taiyo Nippon Sanso. The company has made rapid progress in process design, manufacturing, installation and commissioning.
