Under what circumstances is a solar vacuum tube prone to bursting

In summer, the weather is very hot, and the temperature inside the solar tube is very high, but there is no water. At this time, water cannot be injected, otherwise the low-temperature water will burst when it enters the vacuum tube of the high-temperature vacuum tube.

If there is a certain amount of water in the water tank in advance, no matter how many degrees, at this time in the water injection, there will be no explosion, because there is water in the tank, there will be water in the vacuum pipe, the maximum liquid water temperature under atmospheric pressure is 100, and the tap water added by the user must first enter the water tank, after the water in it, it will not blow up the pipe.

Generally it has its own protection, my family has encountered this problem before, due to the water outage, the water tank water is used up, the water is noon, the temperature is very high, the machine shows the temperature is 98 degrees, I want to replenish the water, the machine does not move, after asking the service department to say that the temperature can be replenished after the temperature drops, now I can't make up, and then I made up after about 60 degrees, so it is generally not caused by a burst pipe, because there is protection, the service department also said that if the protection does not work, the water replenishment will cause a burst when the temperature is not waterless.

No, it won't! I'm installing solar and selling!

Because: the situation that will explode is only when there is no water in solar energy and the temperature is very high, such as more than 60-80 degrees, if the water is on, the vacuum tube will explode!

Generally water in the morning and evening! The temperature is below 30 degrees!

The water will not explode in the morning and evening, and the water will not explode when there is water!

Get on the water in the morning and try not to go in the middle of the day

No, only in the case of air drying will be on the water**, if there is no water in the solar energy, it is best to choose the sun is not strong when the water will be on the water to avoid tragedies and accidents.

Solar vacuum tube, solar water heater vacuum tube is the core component of solar water heater, known as the "heart" of solar water heater, the quality of vacuum tube directly affects the service life and performance of solar water heater;

The structure of the solar vacuum tube is like an elongated thermos, with a vacuum between the inner and outer layers. The surface of the inner glass tube is coated with a spectrally selective absorption coating using a special process to maximize the absorption of solar radiation energy.

There are the following reasons why a vacuum tube bursts in solar winter ...

1. The water tank is expanded. Although the solar water heater system is currently a mature technology, the production process is still very different. If the polyurethane insulation layer of the water tank is not matured well, it will produce secondary foaming after high temperature, which can generally be judged visually, that is, whether the insulation layer of the vacuum tube plugging hole of the water tank expands, and this expansion may squeeze the vacuum tube rupture.

2. Quality problems of vacuum tubes. It involves the quality of the manufacturer's vacuum tube production process, that is, whether the stress of the glass ring seal is eliminated in the production process, if there is stress at the ring seal, it is easy to burst the nozzle annoidally, and if the pipe wall is problematic, it is easy to produce crushing rupture.
