Working principle of hot water circulating pump of wall-hung boiler;

The heating system is normal → the pressure of the detection system is normal → the hot water circulating pump works → the water flow switch or the water flow sensor is turned on → the water flow signal is output → the fan is cleaned before entering → the wind pressure is detected to be normal, and all safety devices are normal → the fan is ignited (the fan enters low-speed operation or is turned off by inertia operation) → the primary and secondary electromagnetic valves (the proportional valve automatically enters the ignition volume, and the segmented valve enters the small fire ignition) → ignition → ion flame induction, normal combustion, and the fan enters the normal speed.

2. Figure 2 shows the internal structure of the wall-hung boiler. Different brands of wall-hung boilers may have different internal structures, but they are basically the same.
