The development of centrifuge units

I’m not sure whether the poster is asking about a centrifuge (separator) or a centrifugal (compressor) unit I guess the question is about centrifugal compressors. These devices represent the highest-quality products in the machinery manufacturing industry, and both domestically and internationally, they are controlled by a few major companies. Abroad: GE and Atlas in the United States, Mannesmann in Germany, KKK; in Japan: Mitsubishi Heavy Industries. In China: Shenyang Steam Turbine, Shaanxi Steam Turbine, etc. . . The development trends are, first, larger size, and second, smaller size. Larger size refers to the fact that as chemical processing units become bigger, the machinery used in them also becomes larger. Smaller size, on the other hand, is aimed at capturing a larger market share; manufacturers are willing to produce equipment of smaller size in order to encroach on the market previously occupied by piston compressors.
