What to do if the vacuum tube is blocked by solar energy

There is an exhaust port on the solar water tank. Do not block this exhaust port. If it is a solar water heater project, simply install an exhaust valve where air blockage is likely to occur.

Once the return pipe of the solar water heater is blocked by dirty objects such as scale, the flow of water from the return pipe will be very slow. If the blockage is severe, the solar water will overflow the return pipe. solar vent when solar water is supplied.

To function normally, solar water heaters must be properly maintained. The main interview methods are as follows:

1. Remove dust frequently and keep the transparent cover clean and transparent.

2. Pay attention to protect the integrity of the transparent cover. In areas prone to hail, be aware of atmospheric changes and take precautions againsti-hail timely.

3. The absorbent coating of the heat absorbing plate has a great influence on the efficiency of the collector. If it falls, it must be repaired in time.

4. It is best to paint the solar collector housing with protective paint every 1-2 years to prevent the wooden boards from rotting or the iron plates from rusting.

5. Ensure a good seal of the solar collector shell to prevent rain or dust from entering the collector.

6. Heat-absorbing iron plates, water tanks and pipes should be flushed regularly to prevent rust from clogging the pipes.

7. Replenish water in time to avoid sunburn. For flat type solar water heaters, if the temperature of the heat absorbing plate is too high in the sun, it will easily damage the heat absorbing coating, glass, sealing materialsity and the protective layers of evacuated tube solar water heaters, if; the vacuum tube wall temperature is too high in the sun, the cold will burst.

8. In winter, when the solar water heating system cannot be used normally, drain the water to avoid freezing and cracking. It is best to cover the collector with an opaque material to prevent air drying.
