VIBRATION RELIABILITY AND ENDURANCE OF A CENTRIFUGE FOR SEPARATING SUSPENSIONS

摘要

A model of a centrifuge is developed, critical centrifuge speeds are determined by the Dunkerley and Krylov method, and the expected endurance with centrifuge vibration is determined.rnIn the design, manufacture, and operation of centrifugal equipment, evaluation of their vibration reliability is recommended in order to provide accident-free operation. Here, a knowledge of the range of critical velocities, expected life with vibration, makes it possible to optimize the construction parameters of a device so that during its operation resonance phenomena are avoided, that lead to total breakdown of the device, and also to reduce development costs due to a reduction in the number of full-scale tests [1-4].
