Centrifuge control system and method with operation monitoring and pump control
A system and method for controlling a centrifuge which receives a mixture of liquid and solid particles and separates the liquid from the solid particles. A bowl, along with a conveyor extending inside the bowl, are rotated and the speed of, and the torque applied to, the bowl and the conveyor are detected and corresponding output signals are generated. A variable speed drive pump is provided for pumping the flow of the mixture to the centrifuge. A computer responds to the output signals and controls the speed of the bowl and the conveyor as well as the operation of the pump to attain predetermined optimum operating conditions of the centrifuge.
