Abstract
본 발명은 복수개의 펌프를 사용하여 압력에 따라 자동으로 용수를 공급하는 자동급수 가압장치의 펌프 사용을 조정회로에 관한 것으로서, 본 발명의 목적은 운전개시 시점에서 펌프의 사용빈도 및 부하 상태 그리고 가동 시간에 따른 누적운전량에 따라 복수대의 펌프의 동작을 선택적으로 제어함으로써 특정 펌프에 부하가 편중되는 것을 방지할 수 있는 자동급수 가압장치의 펌프 사용율 조정회로를 제공하는데 있다.The present invention relates to a control circuit for the use of a pump of an automatic water supply pressurization device that automatically supplies water according to pressure by using a plurality of pumps, and an object of the present invention is the frequency of use of the pump at the start of operation and the load state and operation thereof. It is to provide a pump utilization rate adjustment circuit of the automatic water supply pressurization device that can prevent the load from being biased to a specific pump by selectively controlling the operation of a plurality of pumps according to the cumulative operation amount over time.
이러한 목적을 실현하기 위한 본 고안에 따른 자동급수 가압장치의 펌프 사용율 조정회로는 복수개의 펌프에 접속되어 각 펌프의 가동빈도를 측정하는 가동빈도측정부와, 상기 펌프의 부하량을 측정하는 부하량측정부와, 상기 펌프 누적운전시간을 카운트하는 타이머부와, 상기 타이머부 및 가동 빈도 그리고 부하량측정부에서 검출된 값에 운전량 가중치 x1,x2,x3를 적용하여 누적운전량으로 연산하는 연산회로부와, 상기 연산회로에서 출력되는 누적운전량이 임의의 한정운전량을 초과하는지를 판단하는 비교부와, 상기 비교부의 출력과 압력감지부의 출력을 입력으로 하여 펌프의 운전상태와 구운전개시 시점에서 구동할 펌프를 결정하는 순차운전회로로 구성되는 것을 본 발명의 요지로 한다.Pump utilization rate adjustment circuit of the automatic water supply pressurization device according to the present invention for realizing this purpose is connected to a plurality of pumps operating frequency measurement unit for measuring the operation frequency of each pump, and load measurement unit for measuring the load of the pump And a timer unit for counting the pump accumulated operation time, an arithmetic circuit unit for applying the operation amount weights x1, x2, x3 to the values detected by the timer unit, the operation frequency, and the load measurement unit to calculate the accumulated operation amount; A comparison unit for determining whether the accumulated operation amount output from the operation circuit exceeds an arbitrary limited operation amount, and an output of the comparison unit and an output of the pressure detection unit as inputs, and a pump to be driven at the operation state of the pump and the start of baking It is the summary of this invention that it consists of a sequential operation circuit which determines.
