Common troubleshooting methods for single head heating tubes:

1, Unstable resistance value

Unstable resistance value is one of the common faults of single head heating tubes. When the resistance value of a single head heating tube is unstable, it can cause other faults, such as unstable current and insufficient heating power. In addition, the instability of the resistance value can also lead to uneven heating of the heating tube, and even cause serious faults such as short circuits and open circuits in the heating tube. The main reasons for unstable resistance values are as follows:

The surface of the heating tube is contaminated

If the surface of a single head heating tube is contaminated with substances such as grease, dust, and dirt, it will affect the thermal conductivity of the heating tube and cause a change in resistance value.

Heating tube temperature too high

When a single head heating tube is in a high temperature state for a long time, it is easy to cause the internal material of the heating tube to expand and deform, leading to unstable resistance values.

Heating tube aging

As the usage time increases, the heating tube material will gradually age, and the resistance value of the heating tube will also change accordingly.

Solution:

To clean the surface of the heating tube, professional cleaning agents or clean water can be used to remove dirt and dust from the surface of the heating tube.

Properly reduce the working temperature of the heating tube to minimize the damage caused by temperature to the heating tube.

Replace the aging heating tube material.

2, Thermal damage

Single head heating tubes are prone to thermal damage due to prolonged high-temperature operation. Thermal damage refers to the failure or deformation of the internal heating components or metal tubes of a heating tube due to overheating. The main causes of thermal damage are as follows:

Excessive temperature

When the working temperature of a single head heating tube exceeds its rated temperature range, the internal components of the heating tube will be damaged due to overheating.

Overcurrent

If the rated power of the heating tube is not matched properly with a controller with excessive power, the controller will generate excessive current, which can also cause thermal damage to the heating tube.

External shocks

If the external environment causes mechanical impact or vibration to the heating tube, the connectors, metal tubes, and other components inside the heating tube are prone to damage, resulting in thermal damage to the heating tube.

Solution:

Reasonably set the working temperature of the heating tube and carefully select the rated power of the controller.

Avoid external impact and strengthen the protection of heating tubes.
