WNS gas (oil) steam boiler common faults and solutions

1. WNS gas (oil) steam boiler centrifugal pump does not start: first check whether the indicator light of the centrifugal pump is on. Whether the gate valve is open, if the indicator light is not on, check whether the power supply is normal. Are the water supply lines frozen or clogged? Determine if there is any abnormality in the feed water pump. Mainly check whether the pump flywheel is damaged.

Is there any abnormality in the electrode rod in the liquid level gauge? If the electrode of the liquid level gauge is abnormal, remove the electrode rod and check whether there is any dirt on the surface of the electrode rod. Then take certain effective measures to control body temperature and remove dirt; first turn off the power supply in the electrical cabinet, and then wipe the contact points of the relay with sandpaper.

2. The burner starts electrically but does not ignite: check whether the main gas pipeline of the WNS gas (oil) steam boiler is naturally ventilated?

Make sure that the pneumatic valve in the gas system software is sufficient, remove the gas in the burner, and then check the power switch of the burner in the electrical cabinet; the burner is turned off immediately after ignition, which may be due to the problem of the photoelectric battery. Check the photocell of the gas steam boiler, and clean it after disassembly; check whether the gap between the electric fire rod is too large or remove dirt; connect the power supply directly to the burner, and confirm whether it is started.

(1) If the burner starts, make sure that the electrical cabinet is normal;

(2) If the burner starts, make sure the burner motor and the car relay are normal.

3. Continuous starting of WNS gas (oil) steam boiler burner: Check the power switch of the burner in the electrical cabinet and determine the position of the power switch of the burner in the electrical cabinet. Secondly, press and hold the button of the burner relay to see if the burner is stopped due to a momentary change in voltage or air pressure. After connecting the power supply directly to the burner, make sure that the starting is normal. After that, check the working pressure automatic switch, check the wiring of the pressure controller, check the contact point of the ignition car relay in the electrical cabinet, and use sandpaper to control the contact point of the relay after disassembly. The process described should be carried out after the switching power supply is turned off.
