Centrifugal Extractor with Magnetic Clutch for Chemical Productions

Abstract

Two alternative designs of a hermetically sealed extractor, the drive of which utilizes a cylindrical magnetic clutch, are examined. In the first version, the driving half coupling is internal, and the driven half coupling external. In the second version, the driving half coupling is external, and the driven internal. It is shown that as the extractor based on the first design begins to accelerate with use of a frequency regulator that permits smooth variation in current frequency, the maximum angle of mismatch between the half couplings of the magnetic clutch is less then 0.5π rad. The proposed design of the extractor has been tested at an establishment manufacturing radiochemical products, and placed in experimental-industrial service. © 2013 Springer Science+Business Media New York.
