徴とするポンプ吐出し流量制御装置。[Claims for Utility Model Registration] A pump discharge flow rate control device for controlling the total flow rate of fluid discharged by a plurality of pumps, comprising pump number calculation means for calculating the required number of pumps in relation to the total flow rate. Given the data on the number of pumps calculated by this number calculation means and the operation pattern of multiple pumps,
A pump determining means determines whether to start or stop the pump based on these data, and receives data on the number of pumps calculated by the total flow rate and pump number calculating means, and determines the pump discharge flow rate per pump from these data. a pump discharge flow rate determining means, which receives a signal to start or stop the pump from the pump determining means, receives a run signal indicating the operating state of the pump, and starts the flow rate or starts the flow rate of the starting pump based on these signals; A start-up/down control means for controlling the pump's lowering is provided, and the start-up/shut-down control means controls the flow rate control setting value to be held at the immediately previous value from the request to stop the pump until the start of stopping the pump. A pump discharge flow rate control device characterized by:
