Abstract

PURPOSE: To calculate operation and stop points, and make it possible to control speedily and exactly the operation and stop of each pump, by making it unnecessary to set in a multi-point setter each operation and stop point for a plurality of pumps, by providing an arithmetic circuit.
CONSTITUTION: Suppose that No. 1 pump 3, No. 2 pump 4 and No. 3 pump 5 are to be controlled in succession. With respect to an additional operation command to No. 3 pump 5, for example, arithmetic unit 12 calculates its operation point, and this value is compared with the actual water supply, that is, the output of flowmeter 7, and thereby an additional operation command is issued. On the other hand, suppose that No. 1 pump 3, No. 2 pump 4 and No. 3 pump 5 are operated in succession. In stopping No. 2 pump 4, for example, its stop point is calculated, the value is compared with the output of flowmeter 7, and thereby a stop command is issued. In this way, it is possible to control the operation and stop of each pump.
