During the use of electric heating tubes for civil and industrial purposes, some people often have doubts about the longer heating time of the heating tubes. Why does electric heating tubes have the problem of slow heating? Most people believe that the electric heating tube is damaged or there is a quality issue with the electric heating tube. There are actually many reasons for the slow heating of electric heating tubes, and the following will introduce them one by one:
1. The external power supply background also has an impact on the heating rate, and the corresponding electric heating tubes are different under the voltage background of 220V and 380V. The peak electricity consumption or other reasons leading to insufficient power supply voltage can cause the heating tube to work at low power, and the heating rate will also decrease. Therefore, under long-term high temperature conditions, slowing down is a normal phenomenon, and regular rest and health preservation can be adopted to not only ensure the heating rate but also extend the service life.
2. Changes in heating background, whether it is heating the liquid or dry burning, must consider the starting temperature of heating when designing electric heating tubes, because the heating background cannot be completely consistent, so the heating time will become longer or shorter with changes in the starting temperature.
3. In addition, prolonged and uninterrupted use can also slow down the heating of the electric heating tube, because the heating principle of most heating tubes is that the internal resistance wire heats up and then transfers heat. Under long-term high temperature conditions, the resistance value of the resistance wire will increase, resulting in slower heating.
4. The difference in heating time is usually proportional to the power of the electric heating tube, and the higher the power, the shorter the heating time. Therefore, it is necessary to choose an appropriate power before using the electric heating tube.
5. In the case of heating water, due to water quality issues, the surface of the heating tube is prone to water rust. The large amount of water rust can cause a decrease in the heating rate of the heating tube. Therefore, in the case of heating water, if it is found that the heating of the electric heating tube is slow after a certain period of use, the problem of water rust should be considered first. Therefore, considering the heating time, when designing electric heating tubes, the power should be considered as the maximum guarantee for heating rate.
