Performance characteristics of electric heater and precautions for debugging

Now the heater is a common electric heating device. The heater is small in volume, high in heating power and widely used, so we can't leave it more and more. Let me introduce the heater for us so that we can understand and choose correctly.

According to different raw materials, there are ceramic heaters, stainless steel heaters, high temperature electric heaters, casting heaters and so on.

The shell of ceramic heater is stainless steel material, and the internal heating resistance wire and the heat-resistant ceramic are outside. The advantage of this way is that ceramics can prevent corrosion, and the heater is fast and efficient, and it doesn't pollute the environment when used. The ceramic heater is not only harmless to the human body, but also has the advantages to the human body. It is a rare and rare equipment.

Stainless steel heater internal evenly scattered in the interior of the high temperature resistance wire, no filling of the layout, filled with magnesium oxide in crystalline state, when the current through the resistor wire, magnesium oxide crystallization heat outwards floated at the moment it is in high temperature condition, when the heat arrived in adhering to, then arrived at the heating the intention of.　　

High temperature electric heater in other woven strands of resistance wire strands around the outside of glass fiber reinforced refractory fiber layer, the refractory fiber layer weaving wire reinforced refractory fiber layer closely and spread along the length of the resistance wire strand of the double coated layer and the intermediate resistance wire strand formed an integral can be bent according to need fold and with the heated part close touch of direct heating of monomer, monomer according to the shape and size of heating heating objects and repeated around with flake, then a single transverse side by side with metal wire woven together, which can be directly wrapped in fabric by other high temperature electric heating body directly the use of the. 　　

The casting heater is further divided into these kinds: cast aluminum and cast copper heater: tube heating element is poured into aluminum and copper solution to form different shape heater. It is mainly used for heating and heating of plastic machinery, oven, boiling water heater, pipe and non corrosive liquid. Cast iron heater: the electric heating pipe is cast in the iron solution. It is widely used in the die casting machine, such as lock, zipper, hardware, toy and so on. Also called gooseneck nozzle heater heater, divided into two types: an electric heating tube is cast in copper, a heating pipe cast in iron. Other special requirements of the electric heat castings: according to customer needs can be customized to make various specifications of electric heat castings. Titanium heater. Titanium is used as the pipe and sheet for petrochemical, chemical and chemical fiber equipment. It can greatly improve the corrosion resistance of the equipment and extend the service life. However, because titanium is very easy to react with oxygen, hydrogen and other elements in the air to produce brittle oxides, so that the welding of the equipment is difficult to pass. Therefore, the localization of titanium equipment is very arduous.

In addition, there are also oil tank heaters, electromagnetic heaters and so on. The use of each heater is different.

Debugging attention of electric heater:

The air that needs to be heated, flowing through the interior of the air electric heater, will produce pressure loss. The greater the pressure loss, the greater the energy consumption of the fan. It should be improved and innovating from the structure of the air electric heater itself, so as to reduce the pressure loss of the air electric heater itself and minimize the pressure loss.

If the fan stops working in the use of the fan, the air electric heater should be cut off in time. When there is no positive flow of air in the shell, the air electric heater is operated for a long time, so as to avoid the early damage of the heating element.

When starting, the fan must be started first and then the power of the electric heating element is connected. The power of the electric heating element must be disconnected and the fan is stopped. The electric heater is a popular liquid heating device, which can heat the liquid in a relatively short time. If it is not properly handled in the heating process, it will encounter many failures, reduce the service life of the electric heater, and how to deal with the breakdown of the electric heater. The electric heater is used for a period of time there may be not heating phenomenon, this may be because the heating wire internal 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, so to the reconnection line.
