Control system for electrically heated boiler

Abstract

The invention discloses an electric heating boiler control system, which comprises a water level detection unit, a water inlet control valve, an inlet water flow detection unit, an outlet water flow detection unit, a water temperature detection unit, and a detection unit for the outlet water flow detection unit and the inlet water flow detection unit. The controller that compares the difference between the results and adjusts the opening of the water inlet control valve according to the result of the difference comparison 1. According to the detection result of the outlet water flow detection unit, analyze the increase or decrease of water consumption per unit time, and adjust the water consumption according to the analysis result A controller two for adjusting the heating power of the heater used by the monitored boiler, and a parameter setting unit and a display unit respectively connected with the controller one. The invention is reasonable in design, convenient in installation and layout, easy in operation and good in use effect, and can solve the problem of low intelligence in the existing hot water boiler control system and the inability to adjust the heating power of the boiler heater according to the increase or decrease of the amount of heated water. Adaptive adjustment and other issues.

Description

technical field [0001] The invention relates to an automatic control system, in particular to an electric heating boiler control system. 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 temperature in the ...
