What is the working principle of electric heating pipe in the process of production?

Date:2017-12-16 Author:Yicheng network Click:

In the production process of the enterprise, more or less will use the electric heating tube, and because of the advantages of the electric heating tube, so in normal work, it can also effectively help the enterprise to improve the production effect. However, many people are often not familiar with the electric heating tubes, so they are often curious about it in their work. Today, in order to satisfy the curiosity of these people, the heat conduction oil and electric heater manufacturers will introduce the working principle and application scope of the electric heating pipe for you.

Working principle of electric heating tube

The principle of the electric heating pipe is to consume electric energy, convert the electric energy into heat, and heat the material that needs heating. In the actual process, some low temperature fluid through a pipe into the input under the pressure, and the electric heating container along specific converter, through the principle of fluid mechanics with electric heating element in the work of the high temperature heat, the heating medium heating work completed.

In the design, the electric heating pipe outlet temperature sensor ang I go, can automatically adjust the output power of electric heating tube, the output medium is always in a state of constant temperature when the heating element when the hot issues, independent overheating protection device of the heating element will immediately cut off the heating power, heating, avoid because of a coke the material caused by over temperature metamorphism, carbonation, even burn out heating element, effectively ensure the service life of the electric heating tube.

The scope of use of electric heating pipe

The electric heating tube is widely used in many industries, and it will be used more frequently in the following environments.

Hydrocarbon heating, including oil crude oil, heavy oil, fuel oil, heat oil, lubricating oil, stone wax and so on.

Process water, superheated steam, molten salt, nitrogen (air) gas, water gas and other fluids are heated up.

The quality problems of the electric heater and the improper operation of the customer may cause the leakage accident. Let's make a summary here:

Electric heating elements are allowed to work under the following conditions:

The air relative humidity is not more than 95%, no explosive and corrosive gas.

The working voltage should not be more than 1.1 times the rated value, and the outer shell should be effectively grounded.

The insulation resistance is more than 1M Omega dielectric strength: 2KV/1min.

The heating pipe should be fixed, and the effective heating area must be immersed in the liquid or metal solid, and the air burning is strictly prohibited. Found the body surface scaling or carbon, should be cleaned and then, to avoid affecting heat and shorten the service life.

When the air is heated, the components should be arranged in a uniform way, so that the components have good heat dissipation conditions, so that the flow of air can be fully heated.

Heat fusible metal or solid salt, alkali, asphalt, paraffin, should reduce the use of voltage for medium after melting, can rise to the rated voltage.

Heating nitrate should consider security measures, prevention of explosion accident.

The wiring part should be placed outside the insulation layer to avoid contact with corrosive, explosive medium and water. The lead wire should be able to withstand the temperature and heating load of the wiring part for a long time, and avoid excessive force when fastening screw.

The components should be stored in the dry place. If the insulation resistance is below 1M ohma for a long time, it can be dried in oven at 200 degrees, or the voltage is heated up until the insulation resistance is restored.

Magnesia powder outlet of the electric heating pipe, used in place to avoid contamination and water infiltration, prevent the occurrence of leakage accident.
