Why The Heating Speed Of The Tubular Heater Is Slow？
During the use of tubular heaters for civil and industrial use, some customers have questions about the longer heating time of the heating element. Why does the tubular heater have the problem of slow heating? Most people think that the heating element is damaged or the quality of the heating element is defective. In fact, there are many reasons for the slow heating of tubular heaters, and they are introduced one by one below:
1. The external power supply background will also have an impact on the heating rate, and the corresponding tubular heaters under the voltage background of 220V and 380V are different. The peak of electricity consumption is caused by insufficient power supply voltage, which will make the heating element work at low power, and the heating rate will also decrease. Therefore, in the case of long-term high temperature, the slowing down is normal, and the method of regular rest and health can be adopted, which not only guarantees the heating rate but also prolongs the service life.
2. The heating background changes, regardless of whether the heating liquid is still burning in the design of the tubular heater, the heating starting temperature must be considered, because the heating background cannot be completely consistent, so the heating time will increase with the starting temperature The change of length becomes longer or shorter.
3. In addition, long-term uninterrupted service will also slow down the heating of the heat pipe, because most of the heating pipes are heated by the internal resistance wire heating and then heat transfer. The resistance value of the resistance wire will become larger when the temperature is high for a long time. As a result, the heating slows down.
4. Generally, the variation of the heating time is proportional to the power of the tubular heater. The greater the power, the shorter the heating time, so it is necessary to select the appropriate power before using the tubular heater.
5. In the case of heating water, due to the water quality problem, the surface of the heating element is prone to rust. The large amount of rust will cause the heat rate of the heating element to decrease. Therefore, in the case of heating water, electric heating is found after the service period. Slow heating of the tube should first consider the problem of scale. Therefore, considering the heating time, when designing the tubular heater, the power should be considered as a large guarantee for the heating rate.
The above is the reason why the heating speed of the heating element we have arranged is slow. If the tubular heater you buy has this problem, you can refer to the above reasons, and hope it will be helpful to you.
