1. There is no water in the water tank; The function of the vacuum tube is to absorb sunlight and collect heat, then use the heat to heat the water in the tube, so that hot and cold water circulates. the water in the water tank is heated. If there is no water in the water tank, the heat converted by the vacuum tube is the highest. It can reach two to three hundred degrees. If the temperature is too high, the pipe will burst.
2. The water filling time is incorrect. Generally, the water filling time should be three hours before and after sunrise or sunset. If the water is not refilled at the right time, due to this. the high temperature of the vacuum tube, it will explode when exposed to cold water.
Also, it is best to clean it. Over time, there will be too much scale in the vacuum tube and it is easy to explode.
I hope this answerwill be. be useful to you
Solar Love The pipe exploded in ten and a half days.
Small. There are many reasons why hot water pipes in solar water heaters burst. After the solar water tank is empty of water, the vacuum tube temperature is high during the day. If water is added at this time, it is easy to explode. due to the big temperature difference. The sun is very strong and it rains suddenly, which will cause the explosion. The exhaust will not be fed, but this also depends on the quality of the hot water lines to the water heater. the explosion power of the solar water heater is also very low. Considering its slight thermal efficiency, the solar water heater does not have the capacity to cause burns due to explosions.
There are 4 main reasons for tube explosion:
1. Once the solar water tank is empty of water, the temperature of the tube empty will be higher during the day if there is water. is added at this time, the tube will easily explode due to the big temperature difference, maybe the sex is the biggest.
2. When there is less water in the vacuum tube, due to the high temperature, the steam after the water boils rises to the mouth of the tube and condenses into water when it meets cold air. releases a lot of heat and the vacuum tube partially overheats, expands and bursts. But it's less likely.
3. The vacuum tube cannot be insulated due to air leakage, causing the water in the tube to freeze when there is no light, causing the vacuum tube to swell and crack ; 4. In addition, if the installation angle is incorrect, it is also easy to explode the tube;
Usage and precautions:
1. , and half a tank of water loses temperature the fastest, so try to keep the refull water tank.
2. Master the water filling time, try to fill the water in the evening or morning before the sun rises, and read the instructions carefully to master the functions of the instrument.
3. When the temperature is below 0 ℃, it is best to use the water heater water in a small amount and several times a day, relying on the water temperature to increase the pipe temperature.
Of course, the most important thing is to choose a good quality brand. Quality and after-sales service can be guaranteed! Thank you, I hope it can be adopted.
