The cause of the short circuit problem of the single-head heating tube and the installation method

Single-ended electric heating is widely used in mold electric heating process or other industrial electric heating equipment, but poor quality unmodified magnesium oxide powder will absorb moisture in the air, but the short circuit of the double wire of the single-ended electric heating tube is not caused by this. The single-head tube does not need special fixed installation and can be directly placed in the heating channel for heating. The reasons for the electric heating short circuit are as follows:

1. The excessive resistivity of iron-chromium-aluminum as the lead-out wire increases the temperature of the lead-out wire and causes an accident, and it is exposed to the air. The position of the heating zone has moved to the lead-out wire port. Teflon heat exchangers are suitable for both steam heating and hot water heating.

2. The rated voltage of the two wires causes short circuit and excessive temperature.

3. Defects in the module drilling process. The aperture of the mold hole is trumpet-shaped, which affects heat conduction, thereby affecting heat conduction and air breakdown.

4. The tube mouth is loose at the end of the lead-out wire, and the two holes for the lead-out wire are too close to us.

5. The poor quality sealing silicone resin and the ring screw at the root of the lead-out are too tight.

The installation method of the single-end electric heating pipe is as follows:

1. The traditional single-end heating pipe has no special fixed installation. It can be directly placed in the heating channel for heating, or it can be fixed with a bracket for heating.

2. Generally, the baffle-type single-end electric heating pipe needs to punch holes on the installation surface to allow the electric heating pipe to pass through, and the baffle plays the role of fixed support. The baffle-type single-end electric heating pipe has two installation methods: horizontal and vertical. The baffle mainly plays the role of protecting the wire when installed horizontally.

3. The threaded single-end electric heating pipe can be punched with a threaded hole at the location where it needs to be installed, and then the electric heating pipe can be installed at the location with a threaded fixed asset. The advantages of using through-thread are easy installation and use, more convenient replacement, good sealing effect, and good stability.
