Abstract

본 발명은 순환펌프의 안전장치는 순환펌프의 입력관에 내설되는 온도센서 및 압력센서와, 인출선을 통해 상기 온도 및 압력센서에 연결되는 아날로그-디지탈 변환회로와, 상기 아날로그-디지탈 변환회로를 매개로 입력단에 상기 온도 및 압력센서가 연결되고 그 출력단에는 순환펌프가 연결되는 마이크로 콤퓨터로 구성된 것으로 난방환수의 수압이 그때의 물의 증기압보다 낮아짐으로써 부분적으로 증기가 발생할때 나타나는 캐비테이션의 소음을 제거할 수 있고 나방환수의 부족으로 순환펌프가 공회전하게 될때 그 펌프내의 베어링이 훼손되는 것을 방지할 수 있도록 된 것이다.The safety device of the circulation pump includes a temperature sensor and a pressure sensor built into the input pipe of the circulation pump, an analog-digital conversion circuit connected to the temperature and pressure sensor through a lead wire, and the analog-digital conversion circuit. The temperature and pressure sensor is connected to the input terminal and the microcomputer is connected to the circulation pump at the output terminal, and the pressure of the heating return water is lower than the steam pressure of the water at that time to partially eliminate the noise of cavitation generated when steam occurs. It is possible to prevent the bearings in the pump from being damaged when the circulation pump is idling due to the lack of moth return.
