Specific performance:Low level alarm of expansion tank.Answer：Cause of failure:The pipeline system (including heater) has not been replenished in time after oil leakage or degassing. Troubleshooting:Eliminate system defects and add oil.
(Question details) Specific performance:The temperature difference between the inlet oil and the outlet oil temperature of the boiler exceeds the given value.Answer：Cause of failure:(1) The oil supply of the heat oil circulating pump is insufficient.(2) The boiler operates overload.(3) Thermal oil metamorphism.(4) The boiler does not match the heating equipment.(5) Bad insulation effect.(6) There is gas or steam in the thermal oil. Troubleshooting:(1) Remove the faults of oil pump and pipeline.(2) Operate at normal load.(3) Change new oil.(4) Choose proper boiler.(5) Check the insulation layer and repair the loopholes.(6) Remove air or steam. ZOZEN pays much attention to boiler furnace insulation also, the inside is made of high quality insulation material, external use of stainless steel plate, which can maximumly reduce heat loss and improve the operating environment.
Question details (Performance):The steam pipe vibrates violently and has a dull impact sound.Answer: fault reason: There is air in pipeline ; automatic air vent valve is not turned on; or it is out of order. Troubleshooting: Check all the air release valves on the water supply pipe and the air release valves on the top of the boiler tube for gas storage. If the valve fails, it should be replaced immediately.
Question details (performance):The burner motor of the gas boiler is running and the ignition is normal, but it is stopped by failure. Answer: Fault reason:The solenoid valve is not opened because the solenoid valve coil is damaged or the cable is broken. Troubleshooting:Replace solenoid valve or fix circuit failure, check voltage on terminal.
