1. The protection of the radiator during the heating season

Exhaust valve: When the radiator part is not hot, an exhaust valve is required. Open the gas release valve to release the gas until the gas is exhausted. When water overflows, close the bleed valve.

Anti-freezing: In winter, if the radiator stops working for a long time, pay attention to anti-freezing. If necessary, drain all the water in the radiator.

Steam protection: When using a steam heating system, protection measures should be strengthened to avoid injury.

2. Protection of radiator in non-heating season

During the non-heating season when the system is out of service, the radiator should be filled with water, and wet maintenance should be used to avoid oxygen corrosion of the radiator and valves.

When the heat medium is hot water, the oxygen content per cubic meter of hot water should be less than 0.05g. If the heating system design cannot guarantee full water protection, the water in the radiator should be emptied. Be sure not to let part of the water stay in the radiator for a long time, because the oxidation and corrosion inside the radiator will cause great damage to the radiator.

Third, the surface protection of the radiator

It is pointed out that during use, it is necessary to prevent other hard objects from violently impacting and scratching the radiator to avoid spray damage and corrosion of the outer surface. If scratches appear, they should be repaired in time to avoid local excessive oxidation and shorten the service life.

The above is the content of the radiator maintenance that Xiaobian introduced to you. I hope you can maintain it correctly after reading it. Only correct maintenance can prolong the service life of the equipment.
