How to heat the pipeline heater safely

Tubular furnace is a kind of equipment used in work and life, such as electric furnace, soldering iron, electric iron, electric furnace, electric furnace, etc. It belongs to electric heating equipment. The tubular heater is made of nickel chromium alloy, and the resistance wire is above 800 ℃. Due to the large power of the electric furnace, if users do not pay attention to safety, the fire will break out at any time. The reasons for the ignition of the electric heater are: placing the electrified electric heater near or near flammable materials may cause high-temperature combustion for a long time.

The electric heater has no plug, and the wire head is directly inserted into the socket, which is easy to cause short circuit and fire. Third, do not unplug the electric socket when the user leaves. If it is used for a long time, the temperature of the electric furnace will be too high, causing fire of nearby combustibles. After re maintenance, the resistance wire shall continue to be used, otherwise it may cause fire due to line overload.

During operation, inflammables and explosives shall not be placed near the electric heating furnace, and a certain safe distance must be maintained. The electric heater must be placed on the base of non combustible materials without heat conduction. The electric heating shall meet the capacity requirements to safely cut off the power-off hot wire. In any case, industrial electric heaters should have independent circuits.

An important part of the work of electric heating wire is the work of electric heating wire. The quality of electric heating wire determines the quality of heating tube. Through the study of the electric heating wire, the resistance value of the electric heating wire is obtained, so as to determine the power of the electric heating tube. The resistance value has been determined. Under different working voltages, different power effects of electric heating tubes will be produced, and the thermal effect is the same.

Generally, the smaller the resistance, the larger the wire diameter of the resistance wire. When the voltage is fixed, the greater the current passing through the resistance wire. When the current passing through exceeds the load of the resistance wire, it is easy to break or damage. The data show that the smaller the resistance of the heating pipe is, the better. The appropriate resistance should be selected according to the actual situation of the heating pipe and to ensure the normal use of the heating pipe.

Maintenance items of pipeline heater during daily use include:

1. When the heating medium is liquid or water, please open the water valve first. After the water supply of the heater manufacturer is normal, turn on the electric heater. The heating pipe cannot be heated empty. Otherwise, the side is very easy to be damaged.

2. The working medium is ordinary water. After two months of use, the heater needs to be pumped out to clean the scale on the surface of the heating pipe.

3. The electric heating pipe of the pipeline, especially the control part, is a precision instrument. It should be handled with care during transportation. Collision and collision are prohibited. The drum parts shall be lifted reasonably to avoid deformation and damage to the internal heating elements. The electric heating pipe and control cabinet of the equipment shall be placed in the warehouse and shall not be exposed to rain.
