Problems in the use of air duct electric heater

The air duct electric heater can not be heated after being used for a period of time. It is likely that the internal electric heating wire is broken or has poor contact. If it is broken, just connect it again or replace it with a new one, but if it is a poor contact, the circuit needs to be reconnected.
There is also the occurrence of electric leakage. It is necessary to judge the specific location of electric leakage. If it is electric leakage of the electric heater, you can bake it in the oven. If not, you must replace the electric heater. If the leakage is caused by the insulation skin damage of the conductor, it can be wrapped with insulating cloth.
The liquid circulation of the whole system of the explosion-proof electric heater of the reactor is closed. The system is equipped with an expansion container. The expansion container and the liquid circulation are insulated and do not participate in the liquid circulation, but are mechanically connected. No matter whether the temperature of the liquid circulation is high or low, the medium in the expansion container is less than 60 ℃.
The whole liquid circulation is a closed system. There is no absorption of water vapor at low temperature and no oil mist at high temperature. The heat transfer oil can work at a wide range of temperatures; The same machine and the same heat conducting medium can realize temperature control from - 95 ℃ to 200 ℃. Refrigeration capacity range mechanical and electronic valves are not used in the whole cycle system.
The safety of explosion-proof electric heater standard is guaranteed, especially in the production process, the manufacturer needs to complete it according to the technology and performance in the standard. Only in this way can we really occupy a certain advantage in the domestic market. Because in the domestic water heater, the function and effect of the electric heater is relatively obvious. It has the advantages of good heating effect, low energy consumption, fast heating speed and so on.
The new type of explosion-proof electric heating belt has been widely applied to heating equipment, and has improved the advanced and advantageous position in technology. Only in this way can we always achieve a first-class advantageous position in the national market and create the characteristics of the industry. It really creates technical recognition and selectivity.
