Why is the immersion heater easy to burn off?

Water tank immersion heater usually with flange / thread design mostly, because of its high thermal efficiency, easy installation characteristics, mostly used in hotel roof, bathroom tank heating, hydropower plant water circulation equipment, heating large tanks and other daily life and industrial manufacturing. A number of customers have reflected that their previous purchase from others supplier of water tank electric heating tube heat easy to break, need to replace often, very troublesome. Then today we will analyze what are the reasons why the water tank electric heating tube is easy to burn.

The main reasons for the tank immersion heater to burn out.

1. Part of the immersion heater heating area is not completely into the liquid.

If the heating tube part of the heating area is not completely into the liquid, will lead to a rapid increase in the surface temperature of the water tank electric heating tube, to a certain extent will burn the resistance wire, thus affecting the life of the water tank electric heating tube.

2. Serious scale on the surface of the heater.

The more the heating tube scale over the more likely to affect the heat conduction of the heating tube, the temperature of the heating tube surface can not be transferred to the heated liquid in a timely manner, resulting in high internal temperature of the heating tube, heat up and cold shrinkage, serious will also appear burst tube phenomenon.

3. Immersion heater power overload.

In the design of the water tank electric heating tube per meter power range is within 1Kw ~ 3Kw. Generally manufacturers will choose a reasonable power according to the customer's use of the environment, but at most will not exceed 4KW / m. If you exceed the proportional design, the generated power per meter will become larger, and the relative surface compliance will also become larger. The surface load will increase, and the surface temperature of the electric heating tube will become higher, which will cause the electric heating tube to burn out.

4. Improper material selection.

The heated liquid medium contains corrosive, but no choice of corrosion-resistant metal heating tube material. This immersion heater will be used in the liquid corrosion loopholes, resulting in short circuit, or even burned.

So there are many reasons that lead to the immersion heater burned, sometimes it is a cause, and sometimes it can be several reasons together resulting in. Therefore, experienced salesmen in the design of immersion heaters will ask customers in detail about the use of the heating tube environment, so as to avoid these causes of the tank electric heating tube vulnerable to bad reasons, to make cost-effective immersion heaters.
