Abstract

PURPOSE: To perform stable control for a filtration plant, with automatic control from the number of revolution signal by the comparison between delivery water flow or water level with set value and with the feedback signal of the detector of number of revolutions.
CONSTITUTION: The delivery water flow detected with the flow detector 9 is inputed to the regulator. Further, the set value of flow set with the flow setter 11 is inputted to the regulator 6 with the selection of the selector 12. In this case, the regulator 6 compares two inputs to output the result to the number of revolution control unit 7 as the number of revolution signal, and automatic control is made with the feedback signal of the number of revolution detector 8. Similarly, the water level is set with the water level setter 4 and the unit 12 outputs the input from the setter 4, then this set value and the water level signal from the water level detector 5 of the filtration plant 1 are compared with the regulator 6 to output the result to the unit 7 as the number of revolution signal and to perform automatic control with the feedback signal of the detector detector 8. Thus, stable control can be made for the filtration plant.
