As a common combustion equipment, suction burner needs regular maintenance to ensure its efficient and safe operation. The following is a detailed description of the necessity and specific content of its maintenance:

Ⅰ.Why do you need maintenance?

1.Performance maintenance

-Long-term use may lead to carbon accumulation in the gas channel, nozzle blockage or imbalance of air mixing ratio, which will affect combustion efficiency and increase energy consumption.

-Flame instability (such as backfire, flame off) may be caused by aging or pollution of components.

2.Safety assurance

-Carbon accumulation or leakage may cause fire or carbon monoxide poisoning risk.

-Sealing parts aging can lead to gas leakage, so regular inspection is required.

3. Extend life

-Regular cleaning and lubrication can reduce the wear of key components (such as control valves, nozzles).

II. Key Maintenance Items

1. Regular Cleaning

-Nozzle/Gas Channel:

Use a soft-bristled brush or compressed air to remove carbon deposits and oil stains (recommended monthly, more frequently if used intensively).

-Airflow Control System:

Check valve operation for smooth airflow to prevent dust buildup affecting air-fuel ratio.

2.Seal Inspection

-Test gas pipe joints with soapy water solution for leaks, replace aged seals or gaskets.

3. Ignition System Maintenance

-Clean ignition electrodes and adjust spacing to manufacturer's recommended value (typically 2-4mm) to ensure spark intensity.

4.Function Testing

-Observe flame color (normal blue, yellow indicates incomplete combustion), adjust airflow control or gas pressure accordingly.

III. Maintenance Frequency Recommendations

-Daily Inspection:

Check flame condition and listen for abnormal noises before use.

-Monthly Maintenance:

Perform basic cleaning and seal integrity inspection.

-Annual Deep Maintenance:

Disassemble key components for thorough cleaning, and have professional personnel test gas pressure parameters.

Ⅳ.Precautions

-Be sure to turn off the gas source and ensure that the equipment is cooled before maintenance.

-If serious corrosion, deformation or irreparable blockage is found, it is recommended to replace the burner instead of forcing repair.

Regular maintenance can not only reduce the failure rate, but also save about 10%~20% of gas costs.
