Control system for electrically heated boiler

Abstract

The invention discloses a control system for an electrically heated boiler. The system comprises a water level detection unit, a water inflow control valve, a water inflow flow detection unit, a water outflow flow detection unit, a water temperature detection unit, a controller A which compares the difference values of the detected results of the water outflow flow detection unit and the water inflow flow detection unit and adjusts the opening degree of the water inlet control valve according to the comparison results of the difference values, a controller B which analyzes the volume increase or decrease of water consumed per unit of time according to the detection results of the water outflow flow detection unit and adjusts the heating power of a heater used by the monitored boiler based on the analyzing results, and a parameter setting unit and a display unit connected with the controller A. The control system is reasonable in design, convenient in installation and layout, simple in operation and good in use effect, and the problems are solved that the intelligent degree of the existing hot water boiler control system is relatively low, the adaptive adjustments cannot be done to the heating power of the boiler heater based on the increases or decreases in the amount of water to be heated and the like.

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 ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide an electric heating boiler control system with simple structure, reasonable design, convenient installation and layout, easy operation and high intelligence, and good use effect in view of the deficiencies in the above-mentioned prior art. It can solve the problems existing in the existing hot water boiler control system, such as low degree of intelligence, inflexible control mode, and inability to adjust the heating power of the boiler heater according to the increase or decrease of the amount of heated water.
