   Electric boiler There is a knack for fire prevention accident network: electric boilers are indispensable for central heating in winter, but the wiring is hot, and there is a probability of fire accidents. How to avoid fire accidents?

1, that is, it is not easy to place flammable substances (paper products, fabric curtains and other inflammable articles) around the electric cooker which is very anxious.

2, the electric heating device has not been forgotten by the power supply plug and the power plug, and the overload of the electric heating wire or the embrittlement of the power cord of the plug has also caused a fire accident.

3, the use of electric heating furnace time, next to it should always be connected to many people, the time should not be removed power cord plug, many people do not pull the habit of power switch, but this will also promote the fire accident opportunities.

4, if sudden power failure is encountered, the power plug of the electric heater should be unplugged, so as to prevent the sudden increase of the current quantity while causing the fire accident.

In the whole process of the use of electric hot water boiler, fouling is the anxiety and discomfort ingredient that endangers the operation of porcelain pot and its service life, so that the operation of the hot-water boiler can be safely and economically developed, and it is required to miss the dirt settlement.

1, pickling passivation scale cleaning method: acid washing passivation scale cleaning method is to accept large scale sulfuric acid or sodium cyanide to wash. The pickling solution is composed of sulphuric acid adding desulphurization agent or sodium cyanide plus desulphurization agent. This kind of acid lotion can remove dirt in porcelain cooker (except for phosphate dirt), and increase the amount of hydrochloric acid.

2. Cleaning method for equipment scale. When the dirt and slag in the electric heating furnace are loose, the pig iron can be cooled and drained off after the furnace is stopped. After cleaning with purified water, scaling can be carried out with flat shovel, steel brush and hand-held pipe mill.

3, alkali cleaning scale cleaning method: alkali boiling scale cleaning method scale cleaning, the result is better than acid washing passivation scale cleaning method is poor, but after alkali boil because dirt is loose, to be related to the use of sulfuric acid to remove the dirty dirt, before pickling and passivation can also be used alkali boil method to hold a punishment. The electric porcelain pot is easy to control and the reaction force is relatively small.
