The installation depth of the heating tube is incorrect

The installation depth of the heating tube is incorrect

The shallow hole causes the heating part of the heating tube to be exposed after installation, without a good heat dissipation environment, which will cause damage to the heater and may even lead to accidents such as fires.

The hole is too deep, causing the heater to be sealed after installation and the wire to be trapped in a high usage environment. Long term use may lead to problems such as short circuits between electrodes.

Understanding the heating length of a single head heating tube and selecting the appropriate installation hole depth is of great benefit to the heating tube. High environmental humidity or inadequate sealing of heating tubes

When the air moisture around the heating tube is heavy or the sealing end of the heater lead is not tight, moisture is easy to enter the heating tube, and magnesium oxide and water will react chemically, which may cause a short circuit. And the stability of sealed magnesium oxide is very good. Before leaving the factory, the single head heating tube of the heat wave will be effectively dried and drained of moisture, and sealed with excellent sealing materials.

It should be noted that storage and use in high humidity environments can cause a decrease in insulation resistance, but after being powered on, the moisture inside the heater evaporates, and the insulation performance will gradually recover. So if it is necessary to use it in an environment with high humidity, it is recommended to start it with low voltage.

Incorrect power supply voltage and usage power

The power consumption of heating tubes also has a significant impact on their service life. For example, the resistance value of a finished heating tube is fixed. When using a voltage value of 2 times the rated voltage for power supply, the current will also increase by 2 times, and the output power will also increase by 4 times (power=voltage * current). At this point, the heating wire bears twice the current load, and the overall heating core needs to support four times the power output.

The higher the power consumption of the product, the better the required cooling environment. When the heat dissipation requirements of the heating tube are not met, high power will lead to a shortened lifespan of the heating tube, as the internal temperature of the heating tube will exceed the specifications of the heating element.
