Precautions for preventing fire from explosion protection electric heater

The size of the electric heater is small and the power heater is mainly used as a cluster tubular electric heating element.

The heat response is fast, the temperature control precision is high, and the comprehensive thermal efficiency is high. The heating temperature is high: the heater can be designed for the highest working temperature of 850 degrees C. The temperature of the medium is uniform and the precision of temperature control is high. Wide application and strong adaptability: the heater can be applied to explosion-proof or ordinary occasions, explosion-proof grade can reach D II B grade and C grade, and the pressure can be up to 20MPa. Long life and high reliability: the heater is made of special electrothermal material, and its surface power load is low, and multiple protection is adopted, so that the safety and life of electric heater will be greatly increased. Fully automatic control: according to the requirement, through heater circuit design, it can realize automatic control of outlet temperature, flow and pressure and so on, and it can be networked with computer. The energy saving effect is remarkable, the energy produced by electric energy is almost 100% to the heating medium.

Anti explosion electric heater to prevent fire

As the power of the electric heating pipe is relatively large, the fire can occur at any time if the user ignores the safety. So in order to avoid fire, we usually have to do a good job in the following aspects:

It is strictly forbidden to put the electric heating pipe on the combustible or to be placed near the flammable material.

The electric heating pipe should install the plug correctly and strictly prohibit the wire head to be inserted into the socket directly, otherwise the fire will be short circuited.

The user must break off the power supply when leaving.

The resistance wire can not be used again after multiple repairs more than three times, otherwise it will cause the line overload and cause the fire.

The safe cutting flow of electric heating pipe wire must meet the capacity requirement of electric heating pipe

Maintenance of explosion-proof electric heater

Before using the explosion-proof heater, the gas source should be first connected. After the gas is up to the standard, the heater can be energized, so that the explosion-proof electric heater can be prevented from being damaged.

If the gas quantity of an electric heater is stopped suddenly in operation, the power supply must be cut off immediately.

It should be often checked whether the wiring of the electric heating pipe is good or not, and the inspection of the insulation has reached the requirement.

The products of explosion-proof electric heater should be cleaned regularly in time.

Check the control instruments of the explosion-proof electric heater regularly, and measure and correct the insulation, so as to ensure that the insulation layer is intact.
