Abstract

PURPOSE: To prevent non-water feed operation while improving the overall efficiency concerned with the operation of a pump by exercising rotation control coresponding to the head of fluid at any time by automatically varying the set value of a limiter for the lowest limit of the pump according to the head of fluid.
CONSTITUTION: When water is supplied to distributing reservoir 4 from pump 2 by way of water pipe 3 by using pump 1 as much as that flowing out from distributing reservoir 4, the water level of distributing reservoir 4 is measured by distributing reservoir water gauge 5. In recording controller 6, a measurement signal from water gauge 5 and a preset water-level set value are processed by comparing and the output signal of the comparing arithmetic is applied to lowest-limit limiter 7, which sends its output to rotational-frequency controller 8 to adjust the rotational frequency of pump 1, thereby keeping the water level of distributing reservoir 4 constant. Then, nonwater feed operation is eliminated by improving the overall efficiency concerned with the operation of pump 1.
