During the use of the burner, due to improper use or external factors such as mechanical wear, various system faults often occur. Today, we will popularize the burner's ignition system fault, engine flameout system fault, burner non-operation system fault, etc. Next, we, Xuanxuan Technology, will take you to understand what the burner system faults are? And how to deal with them! Under the premise that the ignition system fault is normal, the burner is operated three times continuously. If no ignition is found, it should be judged as an ignition system fault. Corresponding routine inspections must be carried out to detect the fault.
(1) Ignition system fault
Under the premise that everything is normal, the burner is operated three times continuously. If no ignition is found, it should be judged as an ignition system fault. Corresponding routine inspections must be carried out to detect the fault.
1. Gas source system fault Routinely check whether the working pressure of natural gas can be maintained normally at 3-5kpa. Too high or too low will cause the problem of non-ignition.
Solution: Adjust the natural gas pressure regulating valve and adjust the working pressure.
2. Air Inlet System Failure: 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 Failure: If the ignition transformer fails to ignite, or if the ignition electrode is dirty or incorrectly positioned, an ignition system failure 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 Failure: During normal ignition, 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 Failure: All ignition applications are transmitted by the intelligent controller. A faulty intelligent controller will prevent normal ignition.
Solution: Replace the intelligent controller.
(2) Engine flameout system failure When the burner is running normally, it suddenly goes out. This is an engine flameout system failure.
1. The gas source fluctuates, causing the flame to float and then go out.
Solution: Adjust the working pressure and restart.
2. Flame detector system failure When the flame detection probe is grounded during operation, or when it is very dirty, no normal flame can be detected, indicating that the engine has stopped.
Solution: Adjust the specific position of the probe and clean the probe surface. Restart.
3. Power circuit system failure The power supply fluctuates or is missing a phase, causing the engine to stop during the process.
Solution: Contact the welder to regularly check the power supply and wiring method.
(3) Burner non-operation system failure The burner does not operate after pressing the operation switch button for a long time
1. External interlocking system failure The external temperature or working pressure control cannot reach the operating lower limit; regularly check the temperature or working pressure preset value.
2. The internal structure of the burner has not been locked. When the standard air pressure is too high or too low, the wind pressure switch is normally closed and cannot be found, and the air inlet mechanism is in place, it will be displayed and routine inspections should be carried out step by step.
