Thread Content
In chemical production, centrifugal compressors are widely used; some are driven by steam while others are powered by electric motors. Their rotation speeds range from 1,000 to 2,000 revolutions per minute, with some even reaching over 10,000 revolutions per minute. Please share information on what types of measuring instruments and control methods are used for centrifugal compressors in your companies, as well as the applications in which they are utilized.
