What is the reason for the uneven temperature of tubular heater?

The uneven surface temperature of the tubular heater is caused by many reasons. First of all, we know the structure of the tubular heater. It uses a metal tube as the shell, and the spiral heating wire is evenly distributed in the center of the heater. The gap is tightly filled with the oxidation of insulation and thermal conductivity. Magnesium powder, and finally seal the nozzle with sealing glue. Then through the tubular heater structure, we can analyze the reason for the uneven temperature of the tubular heater.

Analysis of the causes of uneven tubular heater temperature:

1. The thickness of the resistance wire inside the tubular heater is uneven.

2. The filled magnesium oxide powder has impurities.

3. The thickness of the magnesium oxide powder in the gap is uneven, the amplitude of the powder feeding equipment is unstable, the uneven guide rod is used to increase the speed, and the powder leakage rate is fast or slow.

4. The position of the heating wire in the center of the tube will be affected more or less when the magnesium oxide powder is poured.

The above points are the main reasons for the uneven heating of the tubular heater. If you want to buy an tubular heater with uniform heating, you should choose a professional manufacturer, which can guarantee the quality of the product.
