1. Gas boiler burner ignition rod does not ignite
Possible reasons include: carbon residue and oil stains in the ignition rod gap are broken. Humid. Leak ; the distance between the ignition rods is incorrect, too long or short; the insulating skin of the ignition rod is damaged and short-circuited to ground; the ignition cable and the transformer are defective: the cable is disconnected, the connector is damaged. , causing a short circuit during ignition; the transformer is disconnected or appears.
Treatment measures include: cleaning, replacement with new ones, distance adjustment, changing wires and changing transformers.
2. The ignition rod of the gas boiler sparks but does not ignite.
The reasons may be: the ventilation gap of the cyclone plate is blocked by carbon deposits, this Whocauses poor ventilation; the nozzle is dirty, clogged or worn; The shock absorber adjustment angle is too small; the distance between the tip of the ignition rod and the front edge of the nozzle is inappropriate (too protruding or retracted); the solenoid valve of the first oil gun is blocked by debris (small oil gun); the oil is too viscous and does not flow easily or the filter system is clogged or the oil valve is not open, causing the oil pump to not absorb enough oil. and the oil pressure is low; the oil pump filter screen itself is blocked; the oil contains too much water (abnormal boiling noise during heating).
Treatment measures include: clean first, otherwise, replace with a new one; adjust size and test; adjust the distance (3~4mm is good, disassemble and clean (clean the parts with diesel); ); check the pipeline and oil filter, the teamment of insulation; remove the oil pump peripheral screws, carefully remove the outer cover, remove the oil filter inside and soak it with diesel, replace it with new oil and try it.
3. When the small fire of the gas boiler is normal and turns into a large fire, it goes out or flashes erratically.
The reasons may be: adjusting the air volume of the gas boiler gas boiler. the large fire damper is too large; the big fire oil valve moves slightly. The switch (the outermost group of dampers) is not set correctly (the air volume is set to be greater than that of the large fire damper); the viscosity of the oil is too high and difficult to atomize (heavy oil); the distance between the cyclone plate and the oil nozzle is inappropriate; High heat oil nozzle is worn or dirty. The heating temperature of the reserve oil tank is too highlifting; high, causing steam to prevent the fuel oil pump from delivering fuel oil smoothly; The oil in the oil boiler contains water.
Treatment measures include: gradually reducing the test; increase the heating temperature; adjust the distance (between 0 and 10 mm); clean or replace; change the oil or drain the water; .
4. The noise from the gas boiler burner increases
The reasons may be: the fuel oil circuit shut-off valve is closed or the fuel supply is insufficient, the fuel oil filter is clogged. ; the inlet oil temperature is low, the viscosity is too high, or the pump inlet oil temperature is too high; the fan motor bearing is too dirty;
Treatment methods include: checking whether the oil pipeline valve is open, whether the oil filter is working properly, cleaning the filter screen of the pump itself; heat theoil or reduce oil temperature; oil pump; replace motor or bearing; clean the fan impeller.
