The electric heating tube does not heat up after being energized

The electric heating tube does not heat up after being energized

1) The resistance wire of the electric heating tube is disconnected. Because the resistance wire is directly energized and burned out due to special reasons, or has been damaged during processing, it can not work normally after energization.

2) The connection terminal of the electric heating tube is not connected with the resistance wire or the connection is poor. During production, when installing the terminal block, it failed to connect with the resistance wire, which caused the current to be different, so it could not generate heat.

3) Abnormal power supply of the electric heating tube or power failure, causing the heating tube to fail to work.

4) The power cord plug of the heating tube is in poor contact with the heating socket, or the power cord wire is disconnected, so that no current flows through the heating tube, which prevents it from heating.

5) The set temperature of the electric heating tube control instrument is lower than the current room temperature, resulting in no output from the solid state relay or power regulator, resulting in the heating tube has been in an unstarted state, so that the heating tube cannot generate heat.

Advantages of single-head electric heating tube

1. Small diameter, 3-25MM can be achieved.
2. The length is not limited, 20-2000MM can be achieved.
3. High power, 2-5 times the power of a normal electric heating tube, which can be achieved (surface area 20 watts/square centimeter), even abroad (surface area 60 watts/square centimeter).
4. It has the characteristics of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, easy installation, long service life, non-polluting, low price, etc. At the same time, it saves electricity and is safe to use. It can be bent into various shapes, light, and easy to disassemble www.superbheater.com
