How to make the electric heating tube last longer

In the process of using electric heating tubes for civil and industrial use, people often have questions about the longer heating time of electric heating tubes. Why do electric heating tubes have the problem of slow heating? Most people think that the electric heating tube is damaged or there is a problem with the quality of the electric heating tube. In fact, there are many reasons for the slow heating of electric heating tubes, which are introduced one by one below:

1. The external power supply background will also have an impact on the heating rate, and the corresponding electric heating tubes under the voltage background of 220V and 380V are also different. If the power supply voltage is insufficient due to power consumption peak or other terminals, the heating tube will work at low power, and the heating rate will also decrease. Therefore, under the condition of high temperature for a long time, to slow down the normal phenomenon, regular rest and health preservation can be adopted, which can not only ensure the heating rate, but also prolong the service life.

2. For the change of heating background, whether the heating liquid is still dry burning, the starting temperature of heating shall be considered when designing the electric heating tube. Because the heating background cannot be completely consistent, the heating time will become longer or shorter with the change of starting temperature.

3. In addition, long-term uninterrupted service will also slow down the heating of the electric heating tube, because the heating principle of most heating tubes is that the internal resistance wire generates heat and then transmits heat. Under the condition of high temperature for a long time, the resistance value of the resistance wire will increase and slow down the heating.

4. Generally, the difference of heating time is directly proportional to the power of the electric heating tube. The greater the power, the shorter the heating time. Therefore, the appropriate power should be selected before using the electric heating tube.

5. In the case of heating water, due to the problem of water quality, water rust is easy to sprout on the surface of the heating pipe, and a large number of water rust will reduce the heat rate of the heating pipe. Therefore, in the case of heating water, if it is found that the heating of the heating pipe is slow after the service period, the problem of water rust should be considered first. Therefore, considering the heating time, the power should be regarded as a large guarantee heating rate when designing the electric heating tube.
