Water level control circuit of electric steam boiler

Abstract

The invention discloses a water level control circuit of an electric steam boiler, and relates to the field of electric steam boilers, and the water level control circuit of the electric steam boiler comprises a commercial power supply module which is used for supplying 220V alternating current to a step-down rectification filtering module and a water pumping module; the voltage stabilizing module is used for stably outputting constant direct current; the water pumping module is used for pumping water to the electric steam boiler; the signal control module is used for controlling the water pumping module to work; compared with the prior art, the system has the beneficial effects that water level supplementation of the boiler is completely intelligent, water supplementation is automatically performed when the water level is too low, water supplementation is automatically stopped when the water level meets the requirement, meanwhile, protection measures are taken, and after the water level meets the requirement and water supplementation is still performed all the time, a working circuit of the motor is directly disconnected, so that energy is saved. And the water level in the boiler can be clearly judged due to the fact that the water level in the boiler can be clearly judged.

Description

technical field [0001] The invention relates to the field of electric steam boilers, in particular to an electric steam boiler water level control circuit. Background technique [0002] An electric steam boiler is a mechanical device that uses the heat energy of fuel or other energy sources to heat water into hot water or steam. The hot water or steam generated in the boiler can directly provide the required thermal energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power plant, or converted into electrical energy through a generator. It is mostly used in thermal power stations, ships, locomotives and industrial and mining enterprises. [0003] At present, the intelligent control of the water level of electric steam boilers on the market often only limits the upper and lower water levels. When a water level monitoring failure occurs, the automatic control of the electric steam boiler to add water will continu...

Problems solved by technology

[0003] At present, the intelligent control of the water level of electric steam boilers on the market often only limits the upper and lower water levels. When there is a water level monitoring failure, the automatic control of the electric steam boiler to add water will continue to add water to the electric steam boiler because it does not sense the upper and lower water level restrictions, causing power failure. The steam boiler is malfunctioning and needs to be improved
