Why doesn’t the fuel burner ignite?
In the process of using a red burner, there are often times when it does not ignite. At this time, if we are not familiar with the equipment data, it can often make it difficult for us to start. In order to avoid wasting our production time, today the editor will explain why the fuel burner does not ignite?
Firstly, check whether the combustion engine is locked, that is, whether the reset button of the combustion engine program controller lights up with a red light (also known as an alarm). If it does not light up, check whether the combustion engine power supply is not inputted.
Since the motor can start normally, it indicates that the oil pump is not stuck. Use a multimeter to measure the resistance of the photosensitive tube at 1K gear.
Press the reset button for 1 second to release the action of the combustion fan, but it does not appear when an electric spark should occur, and then the alarm is locked.
The power supply is normal and the alarm is on. Press the reset button for 1 second to release it; The combustion engine does not operate and the red light goes out but quickly turns red again. This is a malfunction of the flame detection system of the combustion engine. It is because the combustion engine is not on fire, but the combustion engine program controller receives interference signals that believe the flame has formed. This is mostly caused by light leakage in the combustion chamber, damage and short circuit of the photoelectric eye, and short circuit of the photoelectric eye signal line.
Check if the oil circuit switch is open, if there is oil in the tank, if the oil circuit filter and oil pump filter are blocked, if the oil pipe is leaking, if the oil pump is damaged or worn, if the coupling is damaged or slipping, if the solenoid valve fails to open, if the oil nozzle is blocked, etc; Fuel injection can also spray flames, but then lock them in.
If there is an electric spark but no fuel injection or the fuel injection does not form a mist, then lock it. This is because the programmable controller did not detect flames. It may be caused by damage to the photoelectric eye or dirt on the viewing surface, open circuit of the photoelectric eye signal line, damage to the programmable controller, unstable flame, etc.
Generally speaking, many burners use this as a basis for self inspection. This way, if we encounter situations where the burner does not ignite, we can conduct self inspection and identify and solve the problem. If the cause cannot be found, please contact technical personnel immediately for maintenance.
