How does a heater achieve heating and heat generation functions?

When using an electric heater, it is mainly necessary to connect the power supply before heating the heated material. During the heating process, the medium with lower temperature can convert the heat flow passing through the internal container of the electric heater under pressure. The heating medium raises its temperature and obtains the required high-temperature medium when it reaches the outlet of the electric heater. Compared with similar heating equipment, electric heaters have more advantages. It has a very intelligent system that can automatically adjust the output power and maintain a uniform medium temperature. In addition, if the temperature is too high, the protective device of the heater will immediately shut off, effectively avoiding material waste and extending the service life of the heater.

I Stop running: Check if the power supply of the electric air heater is caused by a circuit problem, whether the three-phase electricity is normal or missing phase. If there is a missing phase, promptly seek repair from an electrician; Whether the safety fuse is intact and whether the equipment itself is burnt out; Open the protective cover of the air heater and use a multimeter to check if a single electric heating element is open circuit.

2, Abnormal thermometer display: When the thermometer data of the electric air heater is abnormal, it is necessary to first check whether the air switch is closed, and then check whether the control circuit is intact; After power on, the temperature of the heater is moderate and cannot rise. We need to identify the cause of the malfunction. Firstly, check if the fuse is intact. If there are no issues, check if the heater itself is damaged; When the temperature often drops below 0 ℃ in winter, if no measures are taken, the water inside the heater is prone to freezing, affecting normal operation and potentially causing pipeline explosions. The causes of frost cracking in surface coolers may vary in different regions. In areas with mild temperatures, this may be due to the lack of preheating plates in winter and water in the surface cooler. Freeze after inhaling cold outdoor air. At this time, when not in use in winter, attention should be paid to draining the water from the surface cooler. For example, in southern winter, there are frost cracks in the surface cooler. However, due to the extremely low temperature in specific weather conditions, the return air does not mix well with fresh air, causing outdoor cold air to blow directly onto the surface cooler. We can set up a mixing valve to fully mix fresh air and return air; For three-phase imbalance, we can first check whether the input voltage of the three-phase is out of phase, or open the protective cover of the gas pipeline heater and use a multimeter to check whether it is caused by an open circuit of the electric heating element.
