The possible causes are oil supply pipeline blockage, oil pump not pumping, oil supply pipeline vacuum leakage, etc.Remove the high pressure discharge pipe to check the oil condition of the oil pump. When pumping oil normally, the oil column should be ejected outward.
Another reason why the nozzle does not spray oil is that the solenoid valve is not energized.When the oil break solenoid valve loses power, even if the oil pump is in normal operation, the high-pressure end will not supply oil to the fuel injection nozzle. Only after the controller makes the oil break solenoid valve electrified can diesel fuel be allowed to blow out, the purpose of which is to prevent the original accumulation of diesel fuel in the furnace from deflating when it meets an open fire.Under normal circumstances, the burner carries out a pre-blow air to clean the combustion chamber of residual diesel oil, and then fuel injection ignition.In the pre-blowing stage, although the oil pump motor is running, the oil cut-off solenoid valve is not energized, and the high-pressure diesel oil pumped by the oil cut-off solenoid valve cannot reach the fuel injection nozzle.
