摘要: A centrifugal extractor of non-contact journaled construction is provided in which, even under the environments corrosive gase and mist-like liquid such as nitric acid mist generated reprocessing a spent nuclear fuel, no problem corrosion or deterioration parts occurs high reliability obtained, operation enabled for long period time free from maintenance. rotor 12 housed housing 10 by main shaft 14 rotated driven motor 16. The surrounded drive-portion 30, has thrust magnetic disk 36 on upper end radial disks 46, 48 motor-rotor portion 54 circumference thereof. Thrust bearing electromagnets 38 a, b, 50, 52 stator 56 are incorporated into housing, covered non-magnetic anticorrosive protective plates 40, 42, pipe 64, being also can 58. Slide bearings 66, 68 touch down made fluorocarbon resin disposed inner wall vicinity rotor.
