Attention to installation of electromagnetic heating furnace I: guarantee the circulating pressure of the system
In order to produce a larger additional circulating pressure. The return water pipe of radiator should be higher than that of electromagnetic heating furnace, and the horizontal main pipe of water outlet of electromagnetic heating furnace should be higher than that of radiator.
Installation of electromagnetic heating furnace 2: pay attention to exhaust gas to prevent dry burning
To ensure that there is no air in the system, air resistance will be formed, which will cause water shortage and dry burning of electromagnetic heating furnace, which will cause damage due to rapid heating of heater of electromagnetic heating furnace. Therefore, exhaust gas must be paid attention to during installation.
Especially, the exhaust process is long when the ground heating is used for the first time. It is necessary to repeatedly open the pump circulation and exhaust gas. After all the gas is discharged, the power can be connected and the heating furnace can be turned on. All horizontal pipes shall be installed with slope, and the slope shall be based on the degree that the blisters in water cannot stay at any horizontal pipe, generally 1-3%. Automatic exhaust valve must be installed at outlet pipe and all bosses, and manual vent valve shall be installed at the end of each radiator;
Attention to the installation of electromagnetic heating furnace 3: reducing the circulation resistance of the system
Reduce the circulation resistance to try to achieve "short, coarse, less". The pipeline design is as short as possible; the pipe diameter design is rougher; the resistance links (such as elbows, valves, etc.) are less;
Installation of electromagnetic heating furnace note 4: installation of circulating water pump
Circulating water pump must be installed in return water pipe, and the direction indicated by water outlet arrow of water pump is electromagnetic heating furnace. During operation, the circulating pump must be started first, and then the power supply shall be turned on after the water circulation, and the heating furnace shall be started. When closing, the heating furnace must be shut down first, and then the circulating pump shall be closed.
