テム。[Scope of Claim for Utility Model Registration] In a water pump control system that pumps liquid in a tank using multiple pumps, an operation time accumulation means for accumulating the operation time of each of the plurality of pumps in the tank, and the operation time of the pumps. an operating time upper limit setting means for setting an upper limit of the operating time; a comparison means for inputting the integrated value of each of the operating time integrating means and comparing it with a set value set by the operating time upper limit setting means; and a plurality of pumps. Based on the comparison result of the comparison means and the memory storing the usage priority of the pump, the priority of the pump whose operating time has reached the upper limit is lowered, and the priority of the pump with a lower priority than this pump is lowered. a priority exchanging means for incrementing and exchanging the priorities in the memory; a flow meter for measuring the flow rate of liquid pumped by the pump via a secondary tank; and a measured value of the flow meter and current operation of the pump. A pump control system comprising: pump control means for determining the number of operating pumps based on the number of pumps and controlling operation/stop of the pumps according to the priority order of the pumps in the memory.
