The cause of uneven heating of electric heating tube

- Jul 01, 2019-

The following conditions can cause the electric heating tube to not be able to balance the heat and achieve the desired effect for the following reasons:

 

First, the choice of the resistance wire: the quality of the resistance wire will directly affect the effect of the electric heating tube when in use. The non-standard resistance wire may not be seen from the appearance, but it can be found through the efficiency when used. The low-quality materials are selected, the electrical conductivity is not effective, some of the heat is good, and some of the heat is poor.

 

Second, the resistance wire gap is not uniform: after selecting a good quality resistance wire, it is necessary to carry out the process of spinning, that is, the resistance wire is elongated and wound according to the design requirements. This process tries to ensure that the gap between the resistance wires is uniform. After the power is turned on, it can ensure that the electric heating tube is evenly heated to the object. Otherwise, the temperature in the region with high density should be higher than the small density region. This process is very important.

 

Third, improper filling of magnesium oxide powder: the filling inside the electric heating tube is magnesium oxide powder, and now most factories still use manual filling, which will lead to the internal tightness when filling, the overheating will be slower. And the loose part is hotter faster. Shuanglong has adhered to the quality policy of “rigorous management, excellence, customer satisfaction as the criterion” over the years. The production scale and product quality of the main products of single-head electric heating pipes are in the forefront of the industry.
