During the use of low-nitrogen burners, various system failures are often caused due to improper use or mechanical wear and other external factors. Today, I will popularize the failure of the ignition device system of the burner, the failure of the engine flameout system, and the failure of the burner. System failure, etc.
1. Ignition device system failure
Under the premise that everything is normal, if the burner is operated continuously for 3 times, if no ignition is found, it should be judged as a failure of the ignition device system, and corresponding routine inspections must be taken to detect the failure.
1. Gas source system failure. Check whether the gas pressure can be maintained at 3-5kpa. If it is too high or too low, it will cause misfire.
Solution: Adjust the natural gas pressure regulating valve and adjust the working pressure.
2. Inlet system failure Check the size of the air inlet routinely. When the air inlet is slightly larger, it is very easy to show the problem that the ignition device cannot be turned on frequently.
Solution: Adjust the air intake moderately, but it cannot be completely closed.
3. The metal electrode of the ignition device or the ignition transformer system is faulty. If the ignition transformer does not ignite, or the metal electrode of the ignition device is dirty and the specific position is wrong, the ignition device system failure will be displayed.
Solution: Test whether the ignition transformer can ignite the device, clean the metal electrodes of the ignition device, and adjust the distance between the ignition device to maintain 2-3 mm.
4. When the gas valve group system is faulty, the valve group will open in time when the ignition is normal, and the sound of opening can be heard, and no flame will be created when it cannot be opened.
Solution: Routinely check the coil of the valve group and adjust the opening degree of the valve.
5. Ignition controller system failure All ignition applications are transmitted by the controller, the controller is damaged, and normal ignition cannot be performed.
Solution: replace the smart controller.
2. Engine flameout system failure When the burner is running normally and burning, it is suddenly extinguished, which is a fault in the engine flameout system.
1. After the gas source fluctuates from high to low to cause the flame to float, extinguish it.
Solution: adjust the working pressure and restart.
2. When the flame detector system is malfunctioning, the grounding device of the flame detection probe, or when it is dirty, no normal flame can be detected, indicating that the engine is off.
Solution: Adjust the specific position of the probe and clean the surface of the probe. reboot.
3. The power supply circuit system is faulty. The switching power supply fluctuates high and low or lacks phase, causing the engine to stall during the process.
Solution: Contact the welder to routinely check the switching power supply and wiring method.
3. The burner does not run and the system fails. Press the operation switch button for a long time and the burner does not run.
1. The external connection system is faulty. The external temperature or working pressure control cannot reach the lower limit of operation; routinely check the preset value of temperature or working pressure.
2. When the internal structure of the burner has not passed the standard air pressure is too high or too low, when the air pressure switch is normally closed and cannot be closed, and when the air inlet mechanism is in place, it will be displayed, and routine inspections will be gradually adopted.
