During regular burner operation, various system faults may occur due to improper use or wear and tear of machine parts. Today, we will explain various system faults that may occur during burner operation, including burner failure, ignition failure, and engine flameout failure, as well as how to address these issues.
1. Burner Failure System Failure: The burner does not operate even after pressing the start switch for an extended period.
1. External Locking System Failure: The external temperature or operating pressure control fails to reach the lower operating limit; routinely check the temperature or operating pressure settings.
2. Internal Burner Failure: This will be displayed when the air pressure is too high or too low, the air pressure switch is normally closed, and the air inlet mechanism is in place. Perform routine inspections step by step.
2. Engine Flameout System Failure: If the burner suddenly extinguishes while operating normally, this is a malfunction of the engine flameout system.
1. Fluctuations in the air supply cause the flame to float and then extinguish.
Solution: Adjust the operating pressure and restart the machine.
2. Flame Detector System Failure: During operation, the flame detection probe is grounded or dirty, and a normal flame cannot be detected, indicating an engine stall.
Solution: Adjust the probe's position and clean the probe surface. Restart the engine.
3. Power Circuit Failure: The power supply fluctuates or is missing a phase, causing the engine to stall during operation.
Solution: Contact a welder to regularly check the power supply and wiring.
III. Ignition System Failure
Under normal conditions, if the burner is operated three times continuously and no ignition is detected, it is considered an ignition system failure and appropriate routine inspections are required for troubleshooting.
1. Gas Source System Failure: Regularly check that the natural gas pressure is maintained between 3-5 kPa. Excessively high or low pressures will result in a misfire.
Solution: Adjust the natural gas pressure regulating valve and perform pressure adjustments.
2. Air Inlet System Fault: Regularly check the air inlet size. If the air inlet is slightly larger, frequent ignition misfires may occur.
Solution: Reduce the air inlet appropriately, but do not completely close it.
3. Ignition Electrode or Ignition Transformer System Fault: If the ignition transformer fails to ignite, or if the ignition electrode is dirty or incorrectly positioned, an ignition system fault may occur.
Solution: Test the ignition transformer for ignition, clean the ignition electrode, and adjust the ignition distance to maintain 2-3 mm.
4. Gas Valve System Fault: When ignition is normal, the valve opens promptly and an audible opening sound is heard. If it fails to open, no flame is generated.
Solution: Regularly check the valve coil and adjust the valve opening.
5. Ignition Controller System Fault: All ignition applications are transmitted by the intelligent controller. A faulty intelligent controller will prevent normal ignition.
Solution: Replace the intelligent controller.
