Abstract
A solids-liquid separating centrifuge with bowl and conveyor members rotated about a common axis at a differential speed has means for sensing torsional vibration of at least one of the members about its axis and providing an output representative of the vibration amplitude, and signal means which provides an indicative signal when the output indicates vibration amplitude above a predetermined level. The indicative signal may operate an alarm, or an automated centrifuge throughput reducing system, or both.
Claims13
In solids-liquid separating centrifuge apparatus of the type which includes a rotary bowl member and a rotary conveyor member mounted therein, drive means for rotating said members about a common axis at a differential speed, and feed means for feeding solids-liquid slurry to said bowl member,
- the improvement comprising:
- means for sensing torsional vibration only of at least one of said members about its axis and providing an output which varies in accordance with the sensed vibration;
- signal means connected to said output for measuring the amplitude of said variations thereof and providing an indicative signal when said amplitude is representative of vibration amplitude above a predetermined level;
- and
- means responsive to said signal for adjusting the solids throughput of said apparatus, said adjusting means including feed rate control means.
