A Design Study of a Production Centrifuge with Respect to Maintainability and Condition Monitoring
Starting from basic design data referring to process conditions, a simple centrifuge has been designed for use in production processes involving radioactive liquids. The centrifuge will separate fine solids from liquid. The design study is not concerned with the mechanics of the centrifuge process, previous experimental work had decided the speed (20000 rpm) and centrifuge type (open bowl, 125 mm diameter). For a centrifuge to be used successfully in service, it must be maintainable within a radioactive environment and fault diagnosis equipment should be incorporated to a useful, but not overcomplicated, level.
The paper describes the design work carried out subject to process and environmental constraints. A systematic approach is taken to incorporate condition monitoring equipment at the design stage. Maintainability requirements feature prominently and a complete design of the centrifuge is presented.
