How to understand the knowledge of electric heating elements in metal tubes

1, Metal tube: Its function is to protect the resistance wire, improve the mechanical strength and processability of tubular components, and at the same time, metal is the best thermal conductive material, playing a role in conducting heat;

2, Rintangan wayar: Its function is to convert electrical energy into thermal energy;

3, Insulation material: Its function is to fix the center position of the resistance wire, ensuring that the metal shell is not electrified and easy to export the heat generated by the resistance wire;

4, End sealing material: Its function is to prevent moisture infiltration and ensure a certain peristaltic distance between the pipe and the lead out rod;

5, Lead out rod: Its function is to connect the power cord and leave it as a non heating component inside the tubular component.

Seterusnya, let's talk about the selection and function of insulation fillers between pipes and electric heating wires:

The materials we should choose are generally caustic magnesium, crystalline magnesium oxide, aluminium oxide, and clean quartz sand;

The purpose of selecting materials is: 1. to provide electrical insulation between the heating wire and the tube;

2. Transfer the heat emitted by the electric heating wire to the pipe;

3. Betulkan the spatial position of the electric heating wire;

The sealing materials terutamanya include epoxy resin, organic silicon sealing materials, low melting point glass, Saxon ceramic plugs, and other inorganic adhesives.

The function of the sealing material is mainly to make the insulation filling material easily absorb water and gas in the environment, ensuring that the electric heating tube has good insulation performance.
