Diesel burner troubleshooting

In the troubleshooting of diesel burners, it should be noted that these burners use diesel as fuel and due to the presence of particles and impurities in diesel, it causes these devices to suffer from deposits and cause disturbances in The correct way to operate the device.

In the process of troubleshooting the diesel burner and fixing the problems and defects created in the boiler room burner, there are some common and diverse problems.

Why does the electric motor work in a diesel burner, but the fuel does not come out of the nozzle and as a result, the flame does not form?

1- Gasoline has run out at the source
2- There is diesel inside the source
3- The suction pipe of the pump draws air or is clogged
4- The nozzle is dirty
5- The diesel filter is dirty
6- The diesel pump is defective
7- The ventilation pipe (vent) of the diesel source is blocked
8- The coupling between the electromotor and the pump is defective
9- The pump has no pressure
10- The pump pressure adjustment valve is faulty

When troubleshooting a diesel burner, why does the electric motor work, diesel comes out of the nozzle, but it does not ignite?

1- The connection of the ignition to the relay base is disconnected
2- Spark electrodes are not adjusted
3- The electrodes are connected to the body
4- The electrodes are defective
5- The ignition transformer is defective
6- The spark cables are not connected to the electrodes
7-There is a voltage drop
8- The electric motor draws too much amperage
9- The diesel injection is deviated due to the defect of the nozzle

Why does the electric motor work, diesel comes out of the nozzle, it sparks, but the flame does not form?

1- The nozzle is not fully open
2- The connection is loose
3- The nozzle is far behind the flamethrower
4- The pump pressure is too low
5- The amount and pressure of the air is high
6- Combustion air is not enough
7- There is water inside the diesel
8- Fuel concentration is high
9- The fuel is not properly powdered
10- The spark electrodes are connected to the flame cover or nozzle or are not adjusted
11- Photocell is defective

Why does the blower motor not work in diesel burner troubleshooting?

1- The main fuses of the electric current are burnt
2- The fuses related to the burner are burnt
3- There is a problem with the electric key or the wiring
4- There is a problem with the acoustat or thermostat
5- The wiring of the motor to the relay base is disconnected
6- The electromotor capacitor is defective
7- The diesel pump is jammed
8- The fan does not move. (Stuck)
9- The electric motor is defective
10- The relay is broken

Why does the diesel pump have no pressure?

1- The rotation of the pump is the opposite
2- The pump has air
3-The coupling is defective
4- The filter or diesel filter or pump has been removed
5- The suction pipe is stuck
6- The fuel suction path draws air
7- The pump does not create the necessary vacuum for suction
8- The ventilation pipe of the diesel source is blocked

Why is the diesel pump pressure low?

1- The size of the nozzle is more than the capacity of the pump
2- The nozzle is completely worn out
3- The pump gears are worn
4-Due to the high vacuum of the pump, diesel vaporizes
5- The adjustment valve is worn out or remains open
6- The diesel filter is dirty
7- The smoothness of the pump is dirty
8- The suction path is blocked
9- The electric motor does not have enough speed
10-The lantern or diaphragm is defective

Why is the diesel pump pressure high?

1- Fuel concentration is high
2- In the two-pipe system, the return path is blocked
3- The hub of the bypass path in the single pipe system is not removed
4- The submerged piston of the pump pressure adjustment valve is stuck
