Discussion on the cause of explosion of electric heater

The explosion-proof electric heater is a liquid heating equipment more popular, the liquid can be heated in a relatively short period of time in the heating process if not handled properly, will encounter a lot of trouble, reduce the service life of the electrical heater, how to deal with the explosion-proof electric heater fault?

The explosion-proof electric heater used for a period of time there may be not heating phenomenon, this may be because the heating wire inside the explosion-proof electric heater is broken, treatment method is to cut off the thread or change a new line on the ground, another possibility is that the line loose cause poor contact, this kind of words can reconnection line. In the use of explosion-proof electric heater, if the electric heating tube breaks, the electric heater tube needs to be replaced. Explosion proof electric heater leakage is a common condition, we must first determine the leakage point where, if the heating pipe leakage, oven baked it, if the insulation effect is still not very good, leakage will appear if it is necessary to replace the electric heating tube. Junction box inlet or conductor insulation skin damage will appear leakage phenomenon, can dry, with insulation tape wrapped on the broken place.

Explosion proof electric heater failure to timely find the reason and solve the problem is very important, after using the explosion-proof electric heater in all problems must be handled properly, prevent the occurrence of accidents.

After a period of time, the explosion-proof electric heater will break down because of many factors. Among them, the electric heating tube appears, this phenomenon is most prominent. After the occurrence of such a phenomenon, most people will be attributed to the responsibility of explosion-proof electric heater quality failure, manufacturers in production, Jerry building. In fact, this is not entirely true. The quality problem may be. But today, what we are going to tell you is that there are many factors contributing to this phenomenon. We broadly classify the following points:

The explosion-proof electric heater has not been properly designed before it is manufactured, which involves a size and power setting. The greater the power, the size is not up to the requirements, so when in use, will increase the work load of the heater, the heater inside the heat swell, not send out good, leading to rupture of the humidity sensor probe heater, stainless steel tube, PT100 fluid sensor, solenoid valve, cast aluminum heater, heating coil.

In the production of heater, internal fillers are the basic magnesium oxide, magnesium oxide varieties, quality level is uneven, dragons and fishes jumbled together. Magnesium oxide powder to a high temperature insulation effect on the heater, if the poor quality of the magnesia powder used, so when the heater is working, will lead to internal heat gathering inside, thus breaking the phenomenon, which belongs to the quality problem of electric heater.

Another reason is that when the electric heater is heated to liquid, the surface will gradually produce a lot of scale. At first the scale of our heater also will not cause what harm, but go down for a long time, when the scale reaches a certain thickness, harm the cooling effect of the heater, the heater is not the result of the breakdown of the distance in the distant. This factor is also one of our most common.
