When the electric heater is used in life, it mainly appears in the water tank. During its use, it is important to pay attention to the phenomenon of dry burning, otherwise it will lead to more serious consequences. How are the existing electric heaters reasonably designed in this respect?
If there is no water in the water tank or the water is less than a certain amount when the electric heater is heating, the heating state is called dry burning. This is not the set working state, but because the electric heating system runs unexpectedly. If this phenomenon continues, the consequences will be disastrous.
In order to prevent the electric heater from being in a dry state, the products on the market will be equipped with various temperature controllers or thermal protectors. This kind of accessories can make the heated water break the circuit and stop when the temperature of the test point reaches the set value. Heating; and when the water temperature of the tested point drops to the lower limit, it will automatically close.
The reason why I worry about the dry burning of the electric heater is that the high temperature heat generated by the electric heater is directly transmitted to the connection part of the water tank, and it is repeatedly heated, which damages important parts such as the sealing ring, the insulation layer and the water tank, and harms it. Sex is very big.
When an electric heater is plugged into the water tank of a water heater, it constitutes a storage-type electric water heater. In addition to an automatic reset temperature controller, this equipment must also be equipped with a non-dry-burn prevention device. Automatic reset device to effectively prevent dry burning.
With this device, when the water heated in the water heater is less than a certain amount, it will forcibly disconnect the circuit and terminate the heating. This prevents the serious consequences of the electric heater from dry burning accidents, and also helps To extend the service life of electric heaters.
