Simple Operation High Capacity Electric Water Heater 7000 KW Energy Saving

7,000 KW Non Pollution And Fully Automatic Electric Heating Hot Water Boiler

Hot water boiler maintenance:
1. Hot water boilers should pay attention to the following points during operation:
(1) Do not allow the furnace smoke is burning, because it is easy to burn the coal-throwing door, look at the fire door and curved pipe brick and so on.
(2) If the fan vibration, should stop the inspection, generally for the internal impeller wear, should be replaced.
3. No water should be stored on the ground plane at the bottom of the hot water boiler to prevent wet corrosion of the base.
2. Hot water boiler situ for 2-3 weeks, should be checked once.
(1) From the upper two holes behind the hot water boiler to remove the upper ash in the two wing edgy.
(2) Open the front smoke box and rear inspection hole, if there is ash in the pipe should be removed, such as no ash, can be extended opening time, once a month, such as still no ash, can be extended to 2-3 months to open once, at the same time check whether the smoke box closed tight, pipe end whether leakage, if there should be timely welding.
(3) Properly check the fan triangle belt, in order to prevent slipping when running, reduce the wind pressure on the belt wear.
4. Leakage at the interface of valves and pipe flanges should be repaired.
3. The operation of hot water boiler every 3-6 months, should stop the furnace for comprehensive inspection and maintenance, in addition to doing the above 2 work, the following work must be carried out:
1. Remove the inside of the pot, the water-cooled wall and the scale and sludge inside the left and right container, and rinse it with clean water.
(2) Remove the soot and soot from the water wall tube and the fire surface of the pot.
(3) Check the boiler welding steel plate inside and outside corrosion phenomenon, if there is a serious defect should be repaired immediately, if the defect is not serious, can also be left to the next stop furnace repair, if found suspicious, but does not affect the safety of production, should make a record, for future reference.
(4). After the inspection, the boiler paint can be applied on the fire surface to prevent corrosion.
(5) Check that the rolling shaft of the fan is normal and the wear level of the impeller and housing.
(6) If necessary, the furnace wall and outer mask shell, moisturizing layer, etc. removed, in order to thoroughly check, if found to be seriously damaged parts, must be repaired before continue to use, at the same time, the inspection results and repair conditions, filled in the boiler operation register.
4. Hot water boiler long-term maintenance methods: there are dry and wet method two, stop furnace for more than one month, should use dry maintenance method, stop furnace less than one month can use wet maintenance method.
