ZZR heavy oil burner pump failure and solve gas boiler burner common faults and solutions a Burner pump fault phenomenon troubleshooting 1, turn on the power, press start, the motor does not turn (1) underpressure lock (2) Solenoid valve is not strict, the joints leak, check the lock (3) open the thermal relay (4) conditions at least one circuit does not hold (water level, pressure, temperature and program control is energized start) (1) (3) Burner pump press reset to check whether the components are damaged and the motor current (4) Check if the water level, pressure and temperature are beyond the limit. 2, Purge before starting, but not ignition ) Insufficient electric gas (2) Solenoid valve does not work (main valve, ignition valve) Automatic Fiber Laser Welding Robot Automatic Fiber Laser Welding Robot,Fiber Laser Welding Robot,Optical Fiber Automatic Robot,3000W Fiber Laser Welding Robot Herolaser , https://www.herolasermachine.com
(3) Solenoid valve burned (4) Air pressure is unstable (5) Air volume is too large (1) Check the line and repair (2) Replacement (3) Adjust the air pressure to the specified value Opening 3, Ignition, normal pressure, electric ignition (1) Ignition transformer burnout (2) Burner pump damage or loss of high voltage line (3) The gap is too large or too small, ) Electrode broken or short circuit to ground (5) spacing is not appropriate (1) renewal (2) reinstall or renew (3) readjustment (4) reinstallation or renewal (5) readjustment 4, S after the flame (1) under pressure, the pressure drop is too large, the air supply flow is too small (2) the air volume is too small, the combustion is not sufficient, thick smoke (3) the air volume is too large, Air pressure, clean the filter (2) readjustment (30 readjustment 5, take white smoke (1) air volume is too small (2) air humidity is too high (3) exhaust gas temperature is low Reduce the air volume, increase the inlet air temperature (3) Take measures to improve the exhaust gas temperature 6, the drip of the chimney (1) the ambient temperature is low (2) the small flame combustion process more (3) High hydrogen content, large amount of peroxide generated water (4) Chimney longer (5) Low exhaust gas temperature (1) Reduce the amount of air distribution (2) Reduce the height of the chimney (3) Shutdown throttle position switch signal is not fed back to the program signal Check whether the throttle valve wiring is loose or the switch is malfunctioning Troubleshooting Table:
Gas Boiler Burner Symptom Trouble Cause Remedy General Fault 7, Burner motor does not turn (1) No voltage (2) Fuse damaged (3) Motor failure (4) Control circuit interruption (5) Gas delivery interruption (7) Contactor does not move (8) Thermal relay is damaged (1) Connect the circuit (2) Replacement (3) Repair (4) Find the break point, contact or disconnect the regulator or monitor (5) Open the ball valve (6) Replacement (7) Manual reset test (8) Replacing the thermal relay Air volume is less than 8, the burner motor is running but shut down after the pre-purge combustion The motor is running but shut down after about 20 seconds (only for equipment with seal check) (1) Air pressure switch failure (2) Pressure switch contaminated, blocked tubing (3) Solenoid valve not sealed (1) Replacement (2) Cleaning (3) Removal of seal 9. Burner pump The burner motor runs but stops in pre-purge state after 10 seconds (1) The pressure switch contact is not connected to the operating position (air pressure Too small)
(2) Blower contaminated, thermal following action (3) Burner motor rotating in the wrong direction (1) Adjust the pressure switch correctly, if necessary, replace (2) Clean (3) Power pole ignition failure 10, Burner motor running , The voltage is applied to the controller terminal 16, there is no ignition, shutdown later (1) ignition electrode distance is too large (2) is contaminated (3) ignition electrode or circuit ground (4) ignition transformer failure (3) Exclusion of grounding, replacement of damaged electrode or cable (4) Replacement of ignition transformer Flame not formed 11, Motor running, ignition normal, but shutdown later Malfunction (1) The solenoid valve is not open because the solenoid valve Broken coil or broken cable
(1) replace the solenoid valve or to troubleshoot the failure of the circuit, check the voltage on the terminal 17 12, the burner oil pump with a tightness test device in the device, tight seal; burner motor running, ignition normal, but slightly After the shutdown (no fault display)
(1) Solenoid valve is not sealed (2) Insufficient gas supply (3) Filter blockage (1) Exclusion of seal condition (2) Cleaning or replacement
