It will collapse. According to information from Sohu.com, solar water heaters have experienced inflation and deflation, and the reason is that the water tank is under pressure or negative pressure. The method is very simple, that is, the water tank itself is not under pressure, and a pipe interface should be reserved on the top of the water tank as a water channel. exhaust and air intake. If all the joints of the water tank are tight and the air cannot be discharged normally, the water tank will appear as you mentioned.
The difference between the water supply pressure of the solar booster pump and the pressure of ordinary tap water
This item can withstand the pressure of the tap water pipe by approximately 0.1 to 0.3 kg. /c㎡.
Generally speaking, the pressure of tap water pipes is about 0.1-0.3 kg/c㎡, while the design and lThe load capacity of the solar water heater output is generally between 0.2 and 0.5. kg/c㎡ enters. Therefore, the pressure that a solar water heater can withstand is generally between 0.1 and 0.5 kilograms per square meter.
1. The pressure of this booster pump is already extremely high, reaching 1.0 kg/cm². It would be better to replace it with a smaller booster pump (the lift is 12 meters, which is equivalent to the booster pump. The pressure can be reduced without loss of pressure). When the water reaches a height of 12 meters, a water column of 10 meters is equivalent to 1 atmospheric pressure);
2. the supply (at the booster pump) is 2 meters lower than the height of the water source, the pressure loss is 0.2, and there is still almost 1 kilogram of pressure, this pressure is still too high (a tap outlet with more than 0.2 kilograms is sufficient);
3. LCity tap water should generally have a pressure of 2 to 3 kilograms. For a 6-story building, it can guarantee water supply up to the top floor. If you use water on the second floor, the tap water pressure must be guaranteed. However, the solar water heater is equipped with a vent port to prevent vaporization due to excessive temperature, so it is usually located at "zero pressure". an elevated position and uses gravity to generate water pressure. , the situation you mentioned is at a low level, and a booster pump is indeed needed
4 It is difficult to use solar energy; should be transformed into a closed pipeline (losing the superheated steam exhaust function), and it should also be installed a pressure protection/steam exhaust valve, and also check whether the collecting tube can withstand the pressuretap water.
