Integrated control system used for electrically heated boiler

Abstract

The invention discloses an integrated control system used for an electrically heated boiler. The integrated control system used for the electrically heated boiler comprises a water level detection unit, a water inlet control valve, a water inlet flow detection unit, a water outlet flow detection unit, a water temperature detecting unit, a first controller which conducts difference value comparison to detected results and regulates opening degree of the water inlet control valve according to the difference value comparison results, a second controller which analyzes increase or decrease amount of water use per unit time according to detected results of the water outlet flow detection unit and regulates heating power of a heater utilized by a controlled boiler according to the analyzed results, a parameter setting unit and a display unit. The parameter setting unit and the display unit are respectively connected with the first controller. The integrated control system used for the electrically heated boiler is reasonable in design, convenient to install and arrange, simple to operate and good in use effect. The problems that an existing hot water boiler control system is low in intelligent degree and can not conduct adaptive adjustment to heating power of a heater according to increase and decrease situations of water quantity needed to be heated and the like can be solved.

Description

technical field [0001] The invention relates to an automatic control system, in particular to an integrated control system for an electric heating boiler. Background technique [0002] A boiler is a mechanical device that uses heat energy from fuel or other energy sources to heat water into hot water or steam. The boilers currently used in the market are divided into steam boilers, hot water boilers and steam-water dual-purpose boilers according to the state of the outlet medium. For hot water boilers, if the internal water level of the boiler does not meet the preset requirements, an alarm will be automatically issued to remind technicians to take corresponding measures to avoid safety accidents caused by the lack of water inside the boiler. Therefore, in the actual use process, it is necessary to monitor the water level inside the boiler in real time and maintain the water level inside the boiler at a constant level. At the same time, it is necessary to monitor the water t...
