Duct electric heater common faults and their solutions

As a kind of efficient and convenient heating equipment, pipeline electric heater is widely used in the industrial field. However, after a long time of use, pipeline electric heaters may have some failures. Understanding these common failures and their solutions can help improve the efficiency of the equipment and extend its service life. The following are some common pipeline heater failures and solutions.

1. Electric heaters fail to heat

Reason for failure::

• Power supply problem, electric heater not connected to the power supply or unstable voltage.
• The heating tube is internally disconnected or burnt out.
• Control system malfunction, such as thermostat failure.

cure::

• Check that the supply voltage is normal and ensure that the unit is powered on.
• Check that the heating tube is intact and replace it if necessary.
• Check if the control system is working properly, if there is any damage, you need to repair or replace the relevant parts.

2. Abnormal or fluctuating temperatures

Reason for failure::

• Malfunctioning thermostat, resulting in erratic temperature control.
• Poor connection of the temperature control circuit.
• Carbon or dirt accumulates on the surface of the heating tube, resulting in lower heat transfer efficiency.

cure::

• Check the thermostat and its connecting wires to ensure that the thermostat is working properly and adjusted to the proper temperature.
• Clean the surface of the heating tube and check regularly for carbon and oil deposits and other substances that affect heat transfer.
• Check the control circuits to make sure there are no poor contacts.

3. Equipment leakage

Reason for failure::

• Deteriorated or damaged insulation.
• The power cord or heating tube is in contact with the ground.
• Poor sealing of the control panel or electrical connections.

cure::

• Regularly inspect electrical wiring to ensure that all cables and connectors are in good condition.
• Check the insulation between the heating tube and the housing and replace it promptly if it is found to be aged or damaged.
• Ensure that the equipment is installed in a dry environment and that electrical components are protected from moisture.

4. Overheating of equipment

Reason for failure::

• The thermostat malfunctioned and failed to cut off the power in time.
• Poor water flow or clogged pipes causing the heater to overheat.
• Damaged heating tubes, causing heat to be concentrated in one section.

cure::

• Check the operation of the thermostat to ensure that it can accurately determine and regulate the temperature.
• Clean pipes regularly to ensure fluid circulation.
• If the heating tube is damaged or worn, it should be replaced promptly.

5. Excessive equipment vibration

Reason for failure::

• The heater is mounted precariously and is loose.
• Some parts of the equipment are damaged or unbalanced.

cure::

• Check the installation condition of the equipment to ensure that it is securely fixed.
• Regularly inspect the internal parts of the heater, especially the heating tubes and support structure, to ensure that there are no loose or damaged parts.

Although malfunctions of pipeline electric heaters are common, most of the problems can be solved in time as long as regular maintenance and inspection are carried out. Through rational use, regular cleaning and timely maintenance, you can ensure the normal operation of the equipment and improve its efficiency and service life.
