Shandong Sitong Thermoelectric is a high-quality enterprise specializing in electric heating boilers, gas boilers, and biomass boilers! With the increase in boiler steam capacity, especially after adopting equipment such as deaerators, to ensure steam quality and the normal operation of the deaerator, a continuous water supply automatic control system is required. This system widely adopts a float inductive sensor, consisting of a float sensor, controller, and electric control valve as a regulation system. Its working principle is as follows: the displacement of the float triggers an inductive signal, which is then converted into an electrical signal. The controller generates three-position switch signals for starting, stopping, and shutting down. The Henan hot water boiler automatically operates the water supply control valve opening to maintain the water supply to meet the load demand, keeping the boiler water level within a range of 10-15mm, allowing the water pump to work continuously.
