Vibration attenuation support assembly for a centrifugal liquid processing apparatus

摘要

The vibration attenuation support assembly is utilized in a centrifugal liquid processing apparatus for supporting a rotor assembly, a non-rotatable arm fixed to and forming part of the support assembly and a prime mover and for attenuating vibrations created by an unbalanced mass in the rotating parts of the apparatus. The apparatus comprises a cabinet having sidewalls and a floor and a rotor assembly mounted on the support assembly mounted on the floor. Tubings are coupled directly between a source of the liquid outside of the rotor to receptacles within the rotor without the use of fluid seals and are supported from the stationary arm. The rotor assembly includes structure for guiding the tubings from the stationary arm to the rotor and a drive train mechanism and prime mover for rotating the tubings at a first speed and for rotating the rotor at a second speed twice the first speed. The support assembly includes a weldment for supporting the rotor assembly and prime mover and includes four elastomeric members for mounting the weldment on the floor. The support assembly has a mass greater than the unbalanced mass and in one embodiment the support assembly together with the rotor assembly and prime mover have a mass of approximately 150 kilograms and the unbalanced mass is 30 grams acting at a radius of 5 inches at a rotation of 1400 revolutions per minute.
