What are the precautions for fire prevention of tubular heating element?
The precautions to prevent the fire of the tubular heater are: the wire must be installed with a plug, and the end of the wire must not be directly inserted into the socket;
1. The wire of the electric tubular heating element should be replaced in time if it is aging and damaged. tubular heating element without fuses in the circuit must not be used; when the tubular heating element is in use, someone must take care of it and unplug it when leaving. In the event of power failure during use, Also pull out the plug in time, don't forget.
2. It is better not to use the heating tube for the repaired resistance wire for many times. It should be replaced with a new resistance wire. Flammable and explosive items are strictly prohibited from drying with tubular heating element; electric ovens should be equipped with temperature control devices to prevent the temperature from becoming too high and the baking time to be too long.
3. Electric heater is a kind of equipment used in work and life, such as electric stove, electric iron, electric iron, electric heater, electric oven, electric heating furnace, etc., all belong to electric heating equipment. Therefore, when in use, do not place flammable and explosive items near the tubular heating element, and you must maintain a certain safety distance. The tubular heating element must be placed on the base of non-thermally conductive non-combustible material; the safety cutoff of the wire of the tubular heating element must meet the capacity requirements of the tubular heating element, and the industrial tubular heating element must be equipped with a separate circuit in any case.
4. The resistance wire of the electric heater is made of nickel and chromium alloy, and the temperature of the heating tube in Suwaie is over 800 ℃. Because the power of tubular heating element is relatively large, users accidentally ignore safety, and fires may occur at any time. The resistance wire of the tubular heating element of the electric heating furnace is made of nickel and chromium alloy, and the temperature is as high as 800 ° C or more. Because the power of tubular heating element is relatively large, users accidentally ignore safety, and fires may occur at any time.
5. The first is to place the tubular heating element that is energized near a flammable or flammable material, and the heating tube may cause a fire under high temperature baking for a long time. The electric heater is not equipped with a plug, and the electric wire plug is directly inserted into the socket, so it is easy to cause a short circuit and fire. Third, the user did not remove the plug of the tubular heating element when leaving, the time was too long, causing the tubular heating element to overheat, igniting the nearby combustible materials and causing a fire. Fourth, continued use of the resistance wire after repeated repairs may cause overload of the line and cause fire.
