1. Burner maintenance method
Thoroughly clean the rotor cup, ignition, filter, oil pump, motor and impeller system of the gas boiler burner, add lubricant to the damper linkage; and re-test the combustion of the fuel.
2. Controller maintenance method
Inspection and inspection of electrical components, control of the line, cleaning control box ash, each control point for testing. Finally, the sealing process is carried out mainly to prevent the controller components from getting wet.
3. Water supply system maintenance method
Overhaul the water treatment device to check whether the water quality is up to standard, comprehensively clean the water treatment system, check the operation of the feed pump and the lift, and check whether the valves of each pipeline can be used flexibly. Close the valve after the water is cut off and the system is filled with water.
4. Furnace body maintenance method
Furnace maintenance mainly includes inspection of the operating environment inside and outside the furnace and the appearance of the furnace. The working environment of the boiler must be kept dry and ventilated, and it should not be in a humid environment to prevent corrosion during long-term operation.
