DESCRIPTION AND OPERATION Document No. DER01120
Effective Date 25 May 07 Page 7 of 9
The vibration switch is mounted on the centrifuge frame in an orientation that is most affected by
out-of-balance vibration of the bowl assembly. Clogging of the conveyor or worn bearings may
produce sufficiently high vibration to trip the switch.

CASE, BASE, AND SKID
The stainless steel upper and lower case halves provide a sealed, protective enclosure that fully
surrounds the bowl assembly. The liquid discharge pipe and the solids discharge chute are
installed at the bottom of the lower case half. Mating baffles installed inside the top and bottom
case halves separate the solids and liquid. Bolts secure the top and bottom halves together, and
a rubber gasket in the top case seals the two halves. A separate, two-piece enclosure is provided
for the gearbox at the liquids end of the bowl assembly.
The case is bolted onto the welded steel base assembly, which contains mounting provisions for
the bearing pillow blocks and feed tube support. The base assembly is bolted to the welded steel
skid.
